For those with a 4850 and stock cooler who want more.

[Albyno]

Hey peeps,

Would those who already have a 4850 AND an aftermarket cooler please post with pics of ur cards (as would like to see how well they fit and how much space is taken up). And screen shots of your Idle and Load temps with the cooler your running.

Would like to know what cooler you are using what specs you are running eg. stock clocks/ overclock with stock volts/OC with more volts.

There isnt really any GOOD comparisons on the net atm for how well coolers do on these cards. Maybe we can lead the way + i want to see results before i buy :P.

Cheers Tim

I'm running a VF1000 on my 4850, bios vmod(1.24v).
I've moved my sc to the slot beneath the 4870, made for better airflow to the 4850.

Im eagearly waiting for the Thermalright release of there CF/SLI compatiable low profile heatsink.

I knew I should of tested the Thermalright HR-03GT on one of the cards before I sold it but I didn't want to mess around with all the sinks and such. That card treated my 8800GT very well, so I wouldn't be suprised if it didn't do nearly as well on the 4850.

[Albyno]

thanks Grunion good pics.

keep em coming guys. would love to see some HR03GTs and Acceleros or any other zalmans u have

[Rich_T]

Quick question guys, will all 4850 coolers work with the 4870 and vice-versa?

[jokers_greg]

why are you running a 4850+ a 4870? multiple monitors?

[Essenar]

Chances are he got the 4850 first, decided to crossfire 4870's and is using a 4850 in the meanwhile to simulate a 4850 Crossfire rig until he gets a second 4870.

[grunion]

Quick question guys, will all 4850 coolers work with the 4870 and vice-versa?

Pretty much any cooler that fits a 3850/70 will fit the 4xxx cards.

why are you running a 4850+ a 4870? multiple monitors?

I bought the 4850 to mess around with until the X2 arrived. Also wanted to see for myself if it would CF with one of my 3870X2's..nope.
Liked it so much, I bought a 4870 that I will eventually CF with an X2.
When the 4870X2 arrives, the 4850 will make its way to my secondary rig.

So close :)
I'm moved away from quadfire, not a benchmark ***** anymore.:)

[Albyno]

My HR-03 GT installed in a P182 best combo ever. another to come.
Idle temps of 32c in a 18c room. still need to test load properly but 3dmark06 only had it at 43!!!

[necrokiller]

GPU-Z temps are inaccurate. It always showed my temps to be 10C lower than they were. RealTemp, EVGA Precision and Hardware Monitor all showed the correct same numbers.

Edit: Sorry real temp is just for cpu.

[Albyno]

i was using Hardware monitor and CCC for the temp readings i gave you. both read the same within a seconds delay of eachother if not insinc.

will get a screenshot posted later have it at home. (dam work not having my pics)

[necrokiller]

Sorry I meant the guy above who posted gpu-z screens. dont know why they showed wrong readings for me. I even updated it.

Those temps are pretty good by the way.

[Albyno]

cool - ill be posting them anyway i guess. atleast shows what good air flow and fan positioning can do with a REALLY good pasive cooler

*pics added in the cooling section. - 10 min FUR run maxed out at 65c!*

Looks good
You gonna flip it and add a fan?

[Albyno]

nah keeping it that way will add another one same orentation an let the 120mm in my hdd bay blow over both.

Good job!

I'm thinking of getting the VF1000 as well...actually 2 of them for x-fire.

Can you tell me the max height RAM sinks that will fit under it?

I've already got 1 HR03GT on my 8800GTS, but b/c of the custom RAM sinks on there I don't want to take it off. I also don't know if I can fit another card in there w/ an HR03GT + fan. I see your passive setup Albyno, but I'm volt-modding, and need temps to be as cool as possible.

Psychotron: I'm liking the snapped off heatsink from your stock 4850 cooler ;) Well played

[Psychotron]

Thanks. I actually bought a spare ASUS 4850 cooler and sawed the back off for the mosfet and vrm..incase the card ever dies or something I can rma it with its original intact cooler.

[Albyno]

totaly agree Rustafur starting to wonder if its a better Heatsink the the lil ones with the Thermalright.

Jason im running at 1.2volts would consider higher if software could do it. Also the main reason i ended up going passive was cos my PCIe slot is soooo high up and i want to run crossfire so even the other way i couldnt fit a fan on both.

[Psychotron]

Grunion can you give me your 4850 bios?

Psycho, I love that aqua teen episode. LOL, they need to update, cuz Im pregnant!

[Albyno]

Grunion is that BIOS for a 4870 or 50

[deathman20]

From what it says its a 4850. But 1.3V won't be put into the card per what it says in the bios. 1.2V is max for bios modding.

are sinks really needed on the right side of the card? I've got 2 waterblocks on the way for mine, I may do like you've done with the spare coolers though

[jason4207]

I'd say YES! Those components get blisteringly hot!

I decided to throw my HR03GT on my 4850. I just used some spare HS's, and the VRM's stay around 60*C under load. Much better than the 90*C I was seeing at 1.225v, and the 100*C+ I was seeing at 1.3v on the stock cooler!

I also sinked the memory controller, the vMEM VRM's, and the chip near the vGPU mod point. The memory is responding to extra voltage now! The cooler temps make all the difference. I was stuck at 1000 before, and I'm stable at 1200 now! Also, before I was getting a black screen when I pushed the RAM at all, and now if I push it too far I just get some artifacts.

820/1200 is completely stable at 1.350v-vGPU/2.10v-vMEM under the cooling you see below. I'm sure I can bench it at much higher.

[SenojNW]

Hey folks - looking to upgrade my stock 4850 cooling as what once was a pretty quiet system has been devastated by the fan speed xml mod in order to get some decent idle temps... Thought I would try to replicate the new 'Toxic' cards and use a Zalman VF-900Cu but I'm stuck on what to do with the VRM - I can see a variety of methods here ranging from 'saw off the stock one' to various off the shelf VRM sinks.

Anyone know what the 'Toxic' cards are using in that department and whether it's available retail?

[Rustafur]

It looks like Sapphire just uses some good ol aluminum heatsinks. Id reccomend this kit from Swiftech. (link (http://www.newegg.com/Product/Product.aspx?Item=N82E16835108096)) Copper ram sinks and some aluminum sinks for your VRM's.

Oh, btw, the Sapphire 4850 Toxic is available at the Egg (Link (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102760)) :D

[Albyno]

yea im about to put the swiftech ones that you see on jasons card on mine (the copper ones) by far the best imo

[SenojNW]

Thanks folks...

The Egg don't deliver to Australia unfortunately...

Looking at the attached (found on another forum) there is quite a bit to deal with down the tail end - don't know which are VRM and which are MOSFETS but there is 12 in total that I assume I would need to heatsink.

I like the look of the Swiftech MC14's and they look like the would fit nicely over the bigger grey components nicely (14 x 14mm) but other black chips are tiny - does it matter if you bridge across a few (maybe four judging by the size? looks like you might have done this Jason?) with a single heatsink? Or if the sinks are touching does it matter?

[satansangel114]

This is my 4850 with an accelero S1 and mosfet cooler made from a moded northbridge hs. off a dead asua mb.

[Essenar]

Wow, okay guys:
I ordered the Akasa Vortexx Neo from Sidewinder. I was skeptical after my order because someone here said that they tried the Akasa Vortexx and didn't have very good success with it.

I decided to give it a shot before I gave it thumbs down and man am I happy I did.

Before you roast my temperatures with it, it's important you know that I live in South San Diego County and it's hot. Milk was a bad choice.

Here's my stock temperatures with the stock cooler at 100%:
http://img373.imageshack.us/img373/6753/stock100tg7.jpg (http://imageshack.us)

And man, at that speed it is LOUD. AC MX-2 did not make a noticeable difference.

Then with the Akasa Vortexx Neo-
http://img213.imageshack.us/img213/3527/vortexxea9.jpg (http://imageshack.us)

Not only is this cooler quiet, but it is beautiful and it exhausts the air OUT of the case. Bad air, out! Good air, stay! Uhhh or good air, go INTO heatsink, turn into BAD air and then out!

And the best part is, I didn't crush my core, I put some Zalman VGA Memory heatsinks on the mosfets and the MX-2 hasn't even settled yet, so I know the temps will get better.

Also note the light over-clock. I'll push it to 700 when I know it's not a faulty card and it's broken in a little.

One gripe about the Vortexx is its use of a 3-pin connector, but to be honest I don't like using in-house VGA programs for the fan speed. A 3-pin means I can control it with a fan controller, but I suppose some people would like to set the fan speed based on temp. But you have to know, this cooler is SUPER quiet at 100% so even at idle temps, the fan speed is more than adequate. It's quieter than my Yate Loons.

[SenojNW]

Evening folks! :beer:

Nice work Essenar...

Been meaning to get back with how I went. The new Zalman VF900 is in - and a couple of 800rpm Scythe fans to help out. Some piccies to follow (pls excuse the cheesy Intel stock cooler in the background - have'nt got to that yet...)

http://i532.photobucket.com/albums/ee323/SenojNW/4850_1.jpg
http://i532.photobucket.com/albums/ee323/SenojNW/4850_2.jpg

There is one other fan out of view attached to the side panel of my Antec 300 case that pushes fresh air in onto the VF900. Rigged up an alu bracket for the other to give the VRM's and MOSFET's a bl*w job... I have the standard Antec 300 fans at the top pulling all the hot air out the top of the case - cool air in at the bottom - hot air out the top...

Setup now has me idling at ~32C with the VF900 on max revs and ~37C on 'silent' - under load it peaks out at about 56C regardless of fan speed. Much better than my previous 64C at idle and 89C under load with the stock cooler...

Some overclocking questions though - I've just used CCC Overdrive for a small overclock to 650/1050 - core speed I have taken to 675 OK, but if I go much higher than 1050 with the memory I start to get artefacts running the Crysis benchmark (I've been using this to test). The Sapphire Toxic is clocked at 675/1100 out of the box and my setup is essentially the same now?

Any ideas?

Voltage most likely. You can use ATI Tray Tools to increase voltage with software, but it's not much.

[deathman20]

I can clock my memory up to 1100Mhz on my setup, but really 1075 is the sweet spot for me sadly. Im not sure if it is just a tempature issue or not but 1100Mhz works most of the time with some slight artifacting here and there in certain games. So far my *spot* for clocks on both my cards in CF is 680/1075, single card I can get up to 700/1100 without issues either card. Benchmarking I can hit 700/1100 as well no issues.

Crysis is a good tool for benchmarking. I've seen most of my errors in that game. But as well just recently I found out that Rainbow Vega's 2 actually shows the same signs as well to a lesser degree but its there. I'm guessing because V-Sync is enabled in that is why I don't see it nearly as much since the GPU isn't under massive load. GRID doesn't really show anything for me at all it just crashes when unstable.

[SenojNW]

Deathman - is this with voltage mods or just through CCC? Essenar - I have'nt been able to get ATI Tray Tools to work with the 4850...

So it sounds like 675/1050 that I have been able to get to isn't too far from the mark...

[satansangel114]

SenojNW-Yoy can edit core voltage with the ccc xml. profile, helped to get mine stable @ 700mhz



For this, you will need an HD 4850 (4870 should work as well), and you will need CCC installed. I use the latest "HD 4800 series hotfix" from AMD themselves.

To do this, you simply need to Enable ATI Overdrive, and save a profile. Name it anything you'd like.

Then, go to the following directory:
"C:\Documents and Settings\*USERNAME*\Local Settings\Application Data\ATI\ACE" - for XP/XP x64
"C:\Users\*USERNAME*\AppData\Local\ATI\ACE" - for Vista x86/x64

Open your saved profile XML file in a text editor (i.e. Notepad), and find this line:
<Feature name="CoreVoltageTarget_0">

You want to edit the value of "Want_2" for that. It seems to work in 0.003v increments. The Want_2 value is in millivolts, so 1123 = 1.123v.

My card could not get to 700 MHz core clock (the limit in CCC) with stock volts (1.123v for mine), but it worked fine using 1.158v.

This was discovered actually when using Auto-Tune got me a higher OC, and I noticed that it adjusted the voltage after finding that CCC profiles store voltages. I saved a profile for stock, and OC'd, and I noticed that the Core Voltages were different. Auto-Tune found "1.158v" for me.

Also, this was probably already posted here, but recently bretware of Guru3D discovered that you can also force fan speeds of 4800 series cards in the profiles. For example, I have mine set to 50%:

Code:
<Feature name="FanSpeedProtocol_0">
<Property name="FanSpeedProtocolProperty" value="Percent" />
</Feature>
<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="50" />
</Feature>__________________

I was under the impression that AMD tuned these cards specifically for higher heat capacity and lower noise hence the incredibly low default fan speeds.

Ooh found an article

"All of the Radeon HD 4800-series cards we've tested have produced some relatively high GPU temperatures, and this early X2 card is no exception. When we asked AMD about this issue in relation to the 4850 and 4870 cards now shipping, they told us the products are qualified at even higher temperatures (over 100°C) and tuned for low noise levels. In other words, these temperatures are more or less by design and not necessarily a problem. "

Yes mine was stock volts. 1.123V for mine (according to CCC profile) was what I was using for 675/1075. I nudged it up to 1.15V via bios settings (not sure what actual is still) and at 680/1075, plan on to push it further of course just all in due time.

Always find it intresting that they rather have it run really hot, than cooler. For me cooler is better just because it doesn't heat up the case even more.

[SenojNW]

Thanks guys - would prefer not to muck around with voltages yet - 675/1050 on stock voltages is fine for now. With the temps - in terms of temps in your case I don't think running the GPU cooler makes any difference - it's still producing the same 'amount' of heat in your case - the aftermarket coolers we have installed are just better at getting it away from the GPU... I just didn't like those temps and wanted it lower - just cos... :)

Might be the same amount of heat but its not as much concentrated heat. Thats the kicker. Hotter the area the hotter the components around it will get, if its cooler it will be cooler temps in teh case since it will be more "hot air" around and out of the case.

So yes it is good to get a better cooler.

[satansangel114]

I agree, with the stock cooler and fan at 50% still got hot enough the clear side panel on my case warped in the spot the hot air was hitting it.:eek:

no longer a problem with the S1, in fact case temps droped by 8C ful load.

[Essenar]

I have the best of both worlds. I have a cooler that gets the heat away from my GPU, and it then sends the heat straight out of my case into the air outside my case. :D

[radium]

Well I tried to run COD4 max res and my computer locked up about 15 minutes in. The thing was probably pushing 100+ temps because it was idling at 80 when I rebooted. I did the fan trick and it worked very well but the thing is so damn loud, I may look into one of those aftermarket coolers.

[SenojNW]

you're at the point I was a couple of weeks ago radium... turning the fan up works but it's so damn noisy... just jump on in and get rid of that nasty stock cooler... :)

[SenojNW]

OK - happy... my 4850 is now on a stable overclock of 675/1070 with no artefacts in the Crysis benchmark - getting ~45FPS on 1280 x 1024, DX9, 32bit

Depending on how many fans you have in case but at least in mine, with no holes in the side panel, 45% wasn't bad for idle temps, it was audiable bearly over my case fans. 55% is definatly heard, 65% sounds the same as 55% to me expecially in gaming mode, 80% is ouch, 100% stick my head in a vice.

I'm getting the thermalright T-Rad2 as soon as its released.

[radium]

Edit: Yeah I just made a profile for a 50% manual fan upgrade for when I play games, then when the computer is idling, or I'm browsing the internet I cut it down to 30% with another profile.

Allright I'm leaning towards the zalman vf1000 but I have a couple of concerns for you guys who already put em on.

1. What did you use to compensate for the lack of heatsinks for the MOSFET cooling? (Buy new ones? Hack up the old heatsink)

2. I've heard that the fan on the zalman doesn't fit the fan port of the 4850

3. I've heard sticking the HS's was a complete PITA with the stuff they gave you

I'll answer those questions based on the Akasa Vortexx Neo, so you can have other options.

1. I went to Fry's and bought Zalman's memory heatsinks. They're like 10 bucks, it comes with 8, you'll have 2 left over or 4 left over depending on how you spread them. You can fit 4 over the large mosfets if they're neck to neck with the capacitors, barely NOT touching. Then another 2 on the smaller mosfets. Or you can split 2 on the top 4 and 2 on the small ones. I recommend AGAINST chopping up the stock heatsink. Visiontek is lenient about their warranty when it comes to the heatsink. Just put the stock one back on and you're fine.

2. That's correct. Most of these heatsinks use a 3-pin fan cable so you can attach it to the motherboard or a fan controller. A lot of people like to use third party software to control their video-cards, it's far more compatible to use a 3-pin. They come with a 3-pin to molex adapter or you can attach it to a fan port on the motherboard, turn off smart fan control in your BIOS and use software to control the speed. My Akasa at 100% is dead silent so none of that matters to me.

3. Couldn't tell you as far as the VF1000 goes, but I can tell you mine was smooth. :) It came with rubber spacers already installed on the copper side, and it came with fat little thumb screw thingies for the back of the PCB, along with little plastic spacers. I simply slapped on my Zalman VGA heatsinks, slapped on some thermal paste, took off the plastic cover, put on my heatsink and bam, done deal. 40c idle from 53c idle, 54c load from 70c load. (That's with the stock fan at 100% too, mind you)

could any of you tell me the distance from hole to hole near the mosfets on this card? in inches or mm would be great, I'm thinking of going with one of these, just not sure it'll be long enough http://www.sidewindercomputers.com/miso.html

Thanks

Allright well you're a convincing salesman essenar. Placed an order for a zalman vf1000, arcticlean, and 8 zalman GPU heatsinks. I'll post pics of temps and installation when they come ^_^

Can't wait to stop using the stupid profiles, although with 8.8 catalyst hopefully they'll fix it for the stock users.

Easiest fix is flashing the bios with a decent fan profile that works for your temperatures.

3. I've heard sticking the HS's was a complete PITA with the stuff they gave you

Nope. They are good quality. You just have to hold each sink down for about 30secs for the adhesive to stick properly.

And cleaning the area really well before sticking it. That is a must otherwise it won't stick as well.

[radium]

Yeah I've heard rave reviews about ArctiClean so I bought some with the new HS

Ahh forgot about that.
Yeah as deathman said.

Thanks folks...

The Egg don't deliver to Australia unfortunately...

Looking at the attached (found on another forum) there is quite a bit to deal with down the tail end - don't know which are VRM and which are MOSFETS but there is 12 in total that I assume I would need to heatsink.

I like the look of the Swiftech MC14's and they look like the would fit nicely over the bigger grey components nicely (14 x 14mm) but other black chips are tiny - does it matter if you bridge across a few (maybe four judging by the size? looks like you might have done this Jason?) with a single heatsink? Or if the sinks are touching does it matter?

I used 4 HS's for the 4 grey blocks (MOSFETs?), and 4 HS's for the 8 small black chips (VRMs?).

Yes, they are touching. It doesn't matter as long as nothing conductive bridges any of the IC legs. I used 4 strips of thermal tape on the 8 VRMs such that the tape would never go over the IC legs. My thermal tape is conductive, so I had to be careful.

I initially tried to use some of the Swiftech MOSFET heatsinks and tried them on the four grey chips and 8 black MOSFETS - they don't stick! Don't go near them!

Got some of the Zalman blue one (see my pics above) and they stick great and stay cool - highly recommended... Mine are touching (see above) and it causes no problems...

The sticky pad from the swiftech's may have 'absorbed' the greasy film that was left on the MOSFETs. I've experienced this, and can confirm it based on the fact that I used the same thermal tape, and it wouldn't stick the 1st time, but after replacing the tape w/ fresh stuff it stuck just fine. I had also scrubbed the crap out of the RAM surfaces w/ rubbing alcohol before I started, but it wasn't good enough. I've started using goo-gone and then alcohol, and have had better results.

[SenojNW]

I gave all the surfaces a good clean with ArctiClean and rubbing alcohol before trying the first time - maybe I just got a bad batch of the Swiftechs... Either way the Zalmans did the job...

I thought that Arctic Clean was for cleaning up TIM? I've never used it so I could be wrong.

The stuff on the RAM sinks is a whole other animal.

ArctiClean comes with 2 bottles. One is TM remover which is pretty much goo-gone (it will take off thermal compounds and dissolves the thermal tape as well) and the other is a Surface Purifier. I'm using Swiffy BGA sinks
Sekisui 5760 Thermal Tape and it's holding right tight.:)

ditched the 80mm fans to get 120s. and it made a big differance.

44 load? Damn, think I should put a 120mm SanAce on my HR-03.

At 44C load that puppy as screaming for a volt mod.

44C :)

Thanks death.:beer:

Yeah, Celsius, is what I meant. 44C under load is not bad at all.

[deathman20]

Hehe. Yeah I knew. I typically after I get aftermarket heatsinks 40-48C under load is typically what I achieve.

[satansangel114]

going for the bios mod next, then maby a volt mod.:santa:
