ATI 4870 Heat problem

[Diabolical]

Since the x850 and up, that is a normal temp. You should worry if it goes over 100. Also you can set game profiles in the ccc. I have different settings and different fan speeds for each game. Once the profiles are set you can right click on the ati icon and select a profile. or set a hotkey combination.

I'm running a radeon hd 4870x2 and a 4850 in crossfirex mode.

well all i wanted is my fan to work with faster speed when the temp is getting higher  


i followed those steps using Rivatuner and it helped alot :

Part 1 and part 3 in my case .. part 1 and part 2 in ur case and i guess part 4 is useful for u as well since ur card is x2 and teh crossifre mode  . u wull find useful information

i managed on part 3 to do the method 1 .. method 2 didnt work for me .. now my fan works faster when heat goes high .. my idle temp now is 58 C with 39 % fans peed which is nice and better and the sound of fan is not rly loud

I even made a test with FurMark program (its GPU Burner )  and i made xtreme burning mode test and high temp was 83 C and my fan reached 60%

anyway i guess im satisfied with the card heat right now

You could turn off manual fan control in your ccc and then use rivatuner for fan control. Remember not to use any options except the fan options or it will conflict with your ccc settings.

You could also use ATI Tray Tools or ATI Tool for the fan control. (also don't use any otions except fan control)

End of the day tho, I recommend seting profiles for your games with a set fan speed. Fluctuating temperatures are just as troublesome as high ones.

Do u have the regular 4870 or the x2?  On my x2 it has a masssive metal heat sink that makes a sound that's hardly audible even at 100%. Like a silencer on a gun. The 4850 does make a bit of a noise, but my speakers easily drown it out.

Well i never used the manual fan control on CCC just for testing though but yeah im aware that i shouldn't use 2 tools to control the fan and i have regular 4870  512 mb DDR5

if its not giving you any errors, why are you even try-ing to modify fan speed manualy?

as of default everything works auto, when card reaches more temperature (more load), fan speed will rise (for a new card like that, 99% this feature must be there)

the only thing you can do is make a better cooling system, for start you can open up your PC box, and this will only make fan speed go lower, decreasing noise, which is the only thing you should care for. The card wont run faster on lower temperature, and increasing it's lifetime from 10 years to 15 years has no sense (and you're also decreasing life time of the vent)

well i noticed my fan is not goign any higher fan speed no matter what the temp. is ( in auto mode ) so i had to get that working .. i tried to make it through CCC but it ended with failure .. so i made it through Rivatuner and i disagree with u .. lower temperature gives better performance for video cards and for CPU as well and who gives a shit about lifetime of something .. u change ur whole pc in matter of few years

I still say you should do away with the 3rd party apps. Just set profiles for each game: (http://www.londonbass.com/forum%20pics/random/ccc.png)

For each game follow these rules:

If the game has it's own anti-aliasing options, set the ccc to "use application settings", if not set it to max in the ccc.

If the game has it's own anisiotropic filtering options, set the ccc to "use application settings", if not set it to max in the ccc.

Set Catalyst AI to "Advanced" if it crashes, set it to "Standard", if it still crashes set it to "Disabled"

Set the fan speed to whatever gives you a comforable temperature for that particular game.

Save these settings as a profile named after the game you are playing.

dude, there is no differance in performance if GPU / CPU runs on -50 C or 60-80 C on same clock speed

id love to see some screen(s) showing better performance becouse of temperature

There is better performance based on temperature. But the only way you'd ever notice is if you had a game that pushed the card to it's extreme limit. Also the card in question is designed for heat levels that the original poster is complainaing about. So no he won't see a diff regardless of temperature in this scenario.

extreme limit?
when card will start to burn, fan will start to spin, i cant see any logic why temperature will help? if card specifications is 80 C as normal, why 60 or lower should help? maybe card starts to set auto lower clock speed on too big temperature, but this is an over-heating problem/protection which will probably be shown with a message or errors, and i don't see how some tweaks in CCC or any program can help against that. on all auto it will make 100% fan speed before that will happen

If it doesn't overheat you can overclock it, witch means better performance.

i think 30% is good for both temp and noise level. 70℃ is normal for 4870
