I had recently purchased a XFX Radeon HD 7850 1GB Core edition graphics card. My computer is sitting on my carpeted floor.
My temperatures are idling at 36+ degrees. The benchmarks show that it should idle about 30 degrees. What are your opinions about the cause of the higher temps?
Thirty-six Celsius is perfectly acceptable, you can lower your temperatures by lowering your room ambient temperature and increasing airflow through your case. Temperatures will always fluctuate, so don't worry.
You can always manually increase fans to a higher velocity if you want, but you don't need to. Graphic cards can handle a lot of heat, so it idling at that temperature is nothing to worry over.
I'd also like to know that. My XFX Double D 7870 at 1000mhz clock and 1200mhz memory (factory defaults) hits 75c when doing Furmark bench test and when I over clock to 1100mhz and 1250mhz memory it hit 86c. Are these temperatures safe for Furmark 15 min burn in benchmark test?
