Which cooler for HD 4850?

[NewbieOneKenobi]

Can someone recommend something that has actually worked on the card, other than Accelero S1 rev. 2? Say, Zerotherm CU92? Auras Fridge? Something from Zalman? Are all-copper coolers necessarily better than Accelero?

I'm asking because I'm not really on current terms, I generally buy stuff on internet auctions and just grab the best bargain, so I'd like to have some different options from Accelero S1 rev. 2 just in case. ;)

ac accelero twin turbo. cheap, quiet and cool.
with some as5 you should get a nice drop in temps.

Yep, got one of those..

Absolutely quiet, keeping the card at 40-50°C via Bios mod at 740/1100MHZ.

Really great cooler..

But beware, great is also the size.. It takes 2 slots alone, making the card a 3 slot card!

Thanks, guys! :) Hmmm... Wouldn't I be better off with Accelero S1 rev. 2 and a custom fan or two (I'm thinking 92 to 120, to avoid the noise of 80 mm)? I'm on sick leave now, so I can monitor online auctions and sometimes I get a new Scythe or Thermaltake fan for $2-3, even the 92 or 120 mm ones, so it's less than the difference in prices between S1 rev. 2 and Twin Turbo. What would you suggest in this case?

[bLack0ut]

I have the Accelero S1 rev.2 running behind my monitor caseless, and its close to silent. If it was running in a case, it WOULD be silent -.-.

The Akasa Vortexx Neo. Quiet, cool, comes with the fan already, cheap @ $30.

It's what I had on my 4850 before I returned the 4850 but when I get one again, I'm throwing it on it.

Okay, guys, just to let you know, I've decided to buy Accelero S1 rev. 2. I found a very good price, three quarters of the normal one. I've also been able to get some Scythe and Thermaltake fans for a low price. ;) Thanks. :)

[WonderingSoul]

Those Akasa's are impossible to find. They have been OOS at sidewinder for weeks and weeks now and no other US retailer has them.

[Mr.Guvernment]

i was going to get thw Acc twin turbo, but myself am getting the HR-03 :)

[NewbieOneKenobi]

Guys, just as a side-topic, does Accelero come with fan holes where screws will go in or with some brackets like on CPU coolers?

It's instock now @ Sidewinder :eek:

Remember that any cooler that isn't a full coverage one is gonna require you putting sinks on the RAM and on the chokes, as they get pretty hot. Needless to say when I had RAMsinks on my chokes, they still weren't cooling them properly.

Just bought one.

I knew you would ;) I'm real tempted to as well, but I have to stop spending $ :bang head

See updated post, I bought two :santa::beer:

[ghost_recon88]

Well then sell one to me at a discount :santa::beer:

Problem is, if I buy one...well then I have to buy 2 so one card doesn't feel bad :(

[Alien432]

For $30 bucks for a quiet cooler and runs cooler... It's worth it. I might just buy one to try it out. Ghost if I don't like it I will sell to you !

[ScottinIndy]

I ordered one of the Akasa coolers as well, If I can get a decent temp drop I will be happy, However the main goal is to get some silence compared to the stock 4850 cooler.

[ScottinIndy]

Well the Akasa cooler arrived and is installed, Nice and quiet first off, With stock cooler I was getting idle temps of 52°, Load temps around 71-72°. With the new cooler idle temp is currently 36° and load temps are right around 50-52°. I used AS5 on the core and I have pretty decent airflow in my Rocketfish case with 4 medium speed Yate Loon 120's installed.
All in all, First impression is very favorable, As I said previously any temp drop is a bonus, I was mainly looking for a quieter solution to the stock card and that has been acheived.

[Essenar]

Yeah I really love the acoustics of the Akasa. I went with Zalman BGA ramsinks. $10 at Fry's and I know I could've gotten cheaper stuff online, but they were blue, matched the video card and I was desperate so I drove out to get them.

[NewbieOneKenobi]

Guys. I've gone from 104-105C to 62 C in idle passive. I could do more if I:

1. Removed the preapplied paste, used something else, say a grain of AS5 (not sure, really if at all and if the difference would be more than minimal)

2. Put more effort in applying heatsinks properly, such as trimming the one that comes in the way of the heatpipe, or maybe even used something different from the pre-applied tape-sort-of. Not sure since this stuff actually looked good. That it doesn't stick oh-so-well is a different point.

I'm putting a fan on when it arrives and when I can get some bolts or come up with a different way of mounting (I'm entirely capable of hanging fans on cords to avoid vibration...)

However, the "fun" I had when mounting an Accelero S1 rev. 2 on this Gigabyte card, the less than perfect reason (as described above) and even the difference in prices (normal card + Accelero) suggests that if you haven't bought your 4850 yet, then your best option is to buy a passive version and put a fan on that (picking the best passive solution you can find and the exact fan you like)... Or just buy a Palit version or something else with a good two-slot cooler (not omitting heatsink coverage of RAM and voltage regulators).

What's the best thing, though? I'm rid of the wretched reference fan. Byyyyyye.

Note: The reference cooler, if you can remove it without destroying it, could be put to some better use. I had to damage one screw to pull it off because my screwdriver wasn't a great match with the screws' heads, but since all the other screws went away peacefully, I'm guessing this one was screwed in harder. You may have the exact matching screwdriver or your screws might be more civilised. I'm not sure how many of you know already, but the reference cooler uses thick "tape" as the adhesive, at least on my Gigabyte, but it's probably the same with every vendor. I am guessing that if one simply removed the reference cooler, then removed all that "tape" (it's a thick layer of a gellyish substance looking like chewing gum) and the original paste from the GPU as well, then used a tiny grain of AS5 everywhere and screwed the cooler back on, the temps would fall by a couple of degrees, maybe even more. Since it holds on screws, it doesn't need tape - unless there's something good about this strange adhesive that I don't know.

One more thing, the GPU surface is perfectly polished, better than most heatsink bases. Might be worth a decent heatsink with a mirror base.

Unfortunately, my computer is still not silent because of the "Silent Force" Tagan PSU. Those dual 80 mm fans aren't as silent as they were supposed to be, or even used to be. Guess if you want real silence, you can't go below 12 cm and you might even want 14 cm. Well, everything in time. I'll probably open the PSU at least to put some rubber under the fans and maybe oil them or replace, though that's probably hardly worth the hassle compared to auctioning off the near-new PSU and buying a new one with a bigger fan. Well, my hearing's probably being oversensitive because of all the caffeine and lack of sleep anyway. ;)

And I should have used an orb cooler instead of a tower one for the CPU. Then it'd whip the back of the GPU for some 10-15C idle and reduce the accumulation of heat.

The Palit dual-slot cooler is very nice, this cooler keeps the temps under 55C while Folding 24/7.

[NewbieOneKenobi]

Nice. It did look capable. I once had a Palit 7600 GT. No complaints, although the card died on me within a year. As I remember the temps, it was a bit under 50C in idle, don't remember stress temps. But I'm talking about the standard version of that card, not Sonic. I loved playing melodies on the fins of that heatsink. :D

xigmatecs acclero s1 knoock off with DPT and includes 2 fan is on sale for 3 dollars AMIR... check out hte cyberdeals forum. Supposedly to be even better than the acelero


nm see you have your new cooler already.

Yeah, I'm a little nervous that there aren't any heatsinks on the memory/fets, but there is direct airflow from the fan and it doesn't seem like they're getting that hot to the touch.

[Alien432]

Well the Akasa cooler arrived and installed but it is worse in temp than the stock cooler, temps are the same or even higher. Very disappointing in performance but quieter. It's almost the exact same design as stock cooler but stock cooler seems more solid. Akasa is pretty blue color but a cheaper in quality. I think the problem is in the design as surface levle for cpu the same as memory chips where as stock cooler the cpu area floats allowing a closer contact. Fortunately I ordered the Twin turbo and installed it and got a much better performance and solid cooler. I did notice in GPUz the temps for MEMIO are 8 to 10C higher on twin turbo. Does anyone know why that maybe and is it a problem for me or just the difference because of GPU cooler design?

The bad thing is it crashes when it reaches 75C. I remember seeing someone in this forum say it would do just that when the cooler weren't the stock one. Any idea how to prevent this? The stock cooler would let the card exceed 100C in heat and yet the system wouldn't crash.

[NewbieOneKenobi]

More info. My fans have arrived today. After casually laying an upward-blowing simple 12 cm Xilence on the bottom of my case, I have 40C on the GPU now. And I have a presumably better Thermaltake Thunderblade here. I can replace the previous one with it, or I can even use both, with presumably a better result when I strap them right under the fins properly (I think I'm just going to use some cord and no screws or wires). Alternatively, I have 2 Scythe 92 mm White fans and two 10 cm Kaze Jyu. Those are likely to be even better in terms of power and silence.
