4850 overheating issues

[LoveDuckie]

Hey,

Recently when i'm in games, i'd have automatic fan speed control enabled. Most recently i've been playing Tom Clancy's Rainbow Six Vegas.

That's a massive card stresser, and so it seems when the card gets a high temp, fan speeds increase. Now this is okay if it didn't go up and down like a yo-yo repeatedly.

It never used to do this, and yet after trying older drivers it's still got the same issue.

I know the 4850 is meant to run at high temps under load (80c) but mine as recently been going at 100 and with furmark it's maxes absolutely at 110c, which to me is shocking (and this is with 100% fan speed)

Idle on desktop it's about 63c with 50%.

ATi-Tool shows no artifacts and major distortions, but that temp is bizarre (also this was after doing it for 15 mins).

I also haven't had a system hang.

That's my furmark page ^

So what does everyone think, RMA time?

PS: I did get it from OcUK

PSS: Hello! (I haven't introduced myself yet, sorry!)

Mine idles at 54 degrees on desktop and about 60 in-game (with the fan set at 50%)

Stock cooling?

If so, then yes I think i'll call up OcUK on monday and see what the verdict is.

Try using manual fan control.

I use manual for mine, for desktop use i have it set to 35%, where it idles around 75-77 (which is fine for just general desktop use, i.e broswing the web etc... ), and then when i go to game, i up it to about 55% and it goes to around 80% which is fine, thats also on the stock reference cooler.

Is that standard clock speeds iswell?

Why does the 4850 get hotter than the 4870 or X2? I know some versions don't like the HIS Ice models.

Because for some misguided reason the manufacturers set the fan speeds too low !

Yeah doesn't affect the clocks, just unlock the Overdrive by clicking on the key, and then you can change the fan speed with the slider.

And added a single slot cooler for such powerful technology I would imagine.

That's just a guess though.

No, In fairness it's about the best and most efficient single slot cooler around and could only be marginally improved by venting some of the hot exhaust through the mounting plate (bit tight with current I/O adapters though)

it's Just the fan temp/speed curve has not been given 5 minutes thought !
