ATI Sapphire Radeon HD6850 safe temps?

post #1 of 11
Thread Starter 
Hey,

I am currently running my Sapphire HD6850 on a stock cooler and at 850/1100 with stock voltage. In games like Crysis my gpu gets up to 76C max. Is this a safe temperature to stay at for a few hours while playing games?

Note: I also set a custom fan profile and at 80 percent fan speed the temp gets up to 71C max. Would running the gpu fan at a constant 100 percent while playing Crysis damage hardware or reduce lifespan at all?

Thanks in advance smile.gif

1) yes, 76 C is absolutely a safe temperature for your GPU
2) no, not at all, but you can probably set it lower for less noise.

My fan profile looks like:

I have the normal Sapphire 6850, running 950/1220 w/ stock voltage, fan 45%, max temps in furmark 80'C. \o/
I could also undervolt it on stock clocks to 0.975v fully stable.

Is it possible to do this without ruining the warranty? I have some thermal compound that came with my Mugen 2.

Thanks for the replys everyone smile.gif

Oh and bespreDELL i'm pretty sure its the top one.

Oh and another question, with a stock cooling system, if I run the card at 850/1100 (stock is 775/1000) and the temps do not exceed 75C while gaming is this a perfectly safe/stable card?

Stable is being able to run some stress-tests, benches, and demanding games without a driver crash to desktop or artifacts. You'll have to test it yourself to see where you can and cannot go on your particular chip. I can get mine close to 1100 core without a driver crash, although I get artifacts over 1040ish. I can do 950 core without adding extra volts, and I use 900 core for everyday gaming usage. 75C is a very typical high load temp for modern gpu's, nothing to worry about.

Email someone at sapphiretech and ask them, just be sure to save the email response. Usually they don't mind if you change the TIM, but I would definitely ask. I heard some companies are now putting tamper seals on the screws so you can't even take off the shroud without voiding warranty.

of the VGA fan ?
No, it has some reserve for spinning constantly. For about 50.000+ Hours )))
Good luck in 24\7 gaming )))

But 71C with 80% fan speed is a high value. It can be achieved with thermal compound changing.BUT, if you don't have much experience you can do worst and the result will be higher temperature ((
BUT, if you are satisfied with the noise level, you can live it as it wokrs now. Your temps are very well ))))
