How Hot Does your 8800 GT OC Run?

[laezyre]

I have a stock MSI 8800 GT factory overclocked card with the big double-finned heat sink and copper pipes. It runs at about 65 C during hours of Crysis play, while my E8400 cpu runs at about 45 C with a vendetta cooler. I've removed the decorative stock plastic sheild over the heatsink for better air flow. This did not change anything.

Does anyone know the thermal specs of this gpu? I was wondering if this is inline with other overclocked 8800 GT cards.

from what I understand, that's amazing for a GT. Be glad you got one with a non-reference cooler.

Hell, that's about on par with my reference-cooled GTS overclocked.

The stock ( no OC ) 8800 GT with the stock cooler on it can touch 85-90 C in full load, so on 65 C is quite cool. Also, never compare temperatures between a GPU and a CPU, since GPUs can take much higher temperatures then CPUs.

I've got the same card. Mine idles at 34C and I haven't seen it break 60C under load yet. Glad I got it.

It's interesting that the gpu's run warmer than the cpu's. They are made by a similar process and have similar heat intolerances I presume. Are we to expect the gpu's to fail sooner? After all, we probably all expect to replace them more often.

Has anyone else taken off the plastic casing that comes with the card? I was wondering if it had a function like directing airflow.

It's possible that they run on higher voltages, though that's a shot in the dark. edit: NVM, it runs around 1.0 volts./

I took off the stock cover on my BFG to put on a Zalman VF900. With the stocker and stock fan speed, temps got over 100*C during Crysis at stock clock settings. If I ramped up the fan to 70-80%, it'd never get above 80*C, but it was damn loud.

I got the VF900, and now it idles around 40*C and loads around 60*C with the fan on medium and overclocked to 720 core.
