I bought this ASUS card about two weeks ago after my previous card (NVIDIA GTX 480) died on me. Temperatures are monitored via GPU Tweak, I haven't overclocked anything, and all settings are set to factory standards.
When the PC boots, the temperature can be anything between 34 to 40 °C, and over the course of the day, it keeps on randomly rising and dropping. The few applications I run all day are Firefox (lots of different Youtube tabs), VLCplayer, and MS Word. When I play BF3 or World of Warcraft (usually for two hours or so), the maximum temperature never climbs higher than 55°C (with all details set to highest). Is this normal?
Here are my specs:
i7 930 @ 2.80
BeQuiet 530 PSU
1TB Hitachi HDD
HAF 922 case (standard top, back. front fan setup)
The default speed is 20. Today, I changed the setting to user defined via GPU Tweak (40 as base, then 50, then 70, then 100).
At a fan speed of 40, the temperature can still rise to 45+ °C even when I'm only running VLCplayer or a few Firefox Youtube tabs. Doesn't raising the default fan speed to 55 as base value use up a lot more power?
Another weird thing is that, if I reset everything to default via GPU Tweak (fan speed of 20), the temperature sometimes goes back down to 34 to 39 within a minute or so.
