4850: How Hot is Too Hot?

post #1 of 18
Thread Starter 
I'm getting a temp of 99C under FurMark. It may go even higher, since I shut it off before it hit 100. Haven't tried anything else yet. My fan speed is at 65% (~6150 RPM). Can I get away with not buying an aftermarket cooler? I plan on playing CSS, Diablo, and Spore (when it arrives).

that is way too hot if you already had ramp that fan up to 65% I would look into this asap as it seems like a serious issue with your gpu

The normal temps for a 4850 with fan speed 40-50% on idle is 45-50c and like 65-low 70s on load so something is definately wrong with your card.

I set my fan speed to 45%... and my temps are great (IMHO). 42c idle/ 63c load (after 24 hours of GPU2)

You have issues...RMA or Figure out for sure you are running your fan at 65%...

Graphics cards can handle WAY more than CPUs. They can easily manage 100*c

Like others have said, ramp the fan speed till you're under 90c. It can run at or around 100c, but I would try and keep it below 90.

But that's bad for the durability of the card


You can ramp up the fan speed or get an aftermarket cooler

Is that side mount fine above the GPU?
Is it intake or exhaust fan?

For 4850 you would want it to blow air right on to the GPU due to how/where the 4850 pulls air from... If that fan above the gpu is exhaust fan then you are creating a low pressure area where the 4850 is trying to get its fresh air from basically starving it of fresh cool air...

So the fan on the GPU is pulling cool air in, not pushing hot air out? I figured it was pushing hot air out, so I put the GPU case fan on exhaust.

I just ran the CSS Video Stress Test (1680x1050, all High) and CPUID had this to say:



Those numbers include before, during, and after the test. So I'm willing to bet that FurMark was pushing my 4850 way harder than any game will be able to. After seeing these results, I'm not going to RMA (or return to Best Buy ).

So, I'll turn the GPU case fan around. I should probably replace the broken front intake fan on my case, too .

Get an Accelero..

Cut off part of the stock heatsink for the VRAM on the right, and stick the rest of the RAM Sinks on, and you're good to go. I don't go over 52 load, and I have it OC'd to 700, 1120.

Yea, FurMark pushes cards WAY beyond any game I've seen. Aftermarket cooling isn't necessary unless you want to vmod or push your card farther (or want quiet).
