HD4870/4850 Fan Speed Control/Increase

changing the fan speed doesnt void the warranty does it?

and what if I'd oc the card from catalyst control, would that void the warranty?

I would hope not and doubt it would since its a pretty safe OC and ATI software...

no

no

both are completely safe to do

i think if you removed the stock HSF, then it would void warranty.. at least with most vendors.

did this and it's working, thanks guys !

Thanks, I just did it right now and temps dropped to like 50 degrees!

w/ my case and running with default speeds and 50% fan speed, My card's at 49°c. It looks like the card auto-underclocks when I'm not gaming. Hopefully atitool releases something...

How high should i be able to clock the 4850 w/ 50% fan speed?

Just wanted to say my Asus card came with a program called SmartDoctor which auto-throttles the fan speed based on temperatures you decide, I think that this program would work on other cards.

The program is called SmartDoctor, you can find it on the Asus website if you poke around a bit, and it does let you set overclocks but not profiles like the ATI CCC.

You have to disable your profiles in CCC to get it to work I think, I had to click defaults on CCC and then click through the options in smartdoctor to make sure it was on the right setting.

Pretty sure you need to flash Asus bios for that.

EDIT: Sorry I'm retarded ... wow ... been A LONG time since I played with a fresh Windows install ... jeez

Thank you for the info. I now have my 4850's at 50% and I can barely hear them... 9 Fans in my case total. The GPU's Idle at 42

Using 40% mine dropped from 78°C to 44°C.

I'm having the same issue creating a profile. I'm running the 8.8 driver on an E6600@3GHz, with HD4870 on an Abit IP35-E w/4GB Wintec DDR2-800 AMP-X, WinXP Home/ XP-Pro64 (dualboot). I don't have any instability with the card and it seems to run everything fine, but cooler would definately be better. It idles at 75-77 degrees C and maxes out at 84 degrees with HDR test. Here's what I'm doing in exact order...tell me if I'm missing something. I open the CCC, unlock (by checking enable) ATI overdrive and agreeing to permission dialog box. I check stats GPU clock 500, memory 900 for verification. I then click on profile, then profile manager and type a name...say Forty. I enter the same name in the description box, check the box for all control center settings below window, followed by save and activate. I close the CCC and go to C:\Documents and Settings\All Users\Application Data\ATI\ACE...there I see an XML file named profile....NOT Forty.xml as I would imagine it to be. I right click the file, select edit to input the new values...BUT.... Below (on this page) is all that shows up in that file. What am I missing?

It's certainly unacceptable to sell a card like that, where the fan speed is by default
0 means 80 degrees Celsius. I guess everbody knows the boiling point is 100 degrees celsius... WTH!!! I'm very dissapointed by ATI.

RivatTuner 2.10 is out and solves the fan speed issues.

My 4870 when i first got it ran at 80c idle. Recently I used RivaTuner and fixed my fan speed at 50% now my idle temps are at 40c. I also managed to use RivaTuner to overclock the card a significant amount. I am currently running the core clock at 852mhz and the memory clock at 2200mhz. RivaTuner seemed to fix the cooling problems. The noise level of the card to me isn't that loud because I run all my fans at max speed.

Well you would be running the ram at 4400mhz as gddr5 is quad, are you using a stock bios?

Its quad? But the stock settings say 1800mhz and most programs show that I'm at 1100mhz. And yes stock bios.

thx worked for me also

don't know if anyone has mentioned this, but if you have a Crossfire setup the Orange lines indicates the Slave (2nd) vidcard and the Red lines indicate the Master vidcard. ppl would assume (myself included) that the "0" Feature would be the Master but i found it to be the other way around. you can set the Slave card to a lower value since it usually doesn't heat up as much as the Master (unless you've oc'd it higher than the Master, but who would do that!? ~lol~).

anyways, hope that helps.

Thanks for this thread guys, got my 4850 down from 83C to 52C (so far...got it running at 80% since the rest of my system is nearly silent it doesn't bother me to much...yet).
