I just purchased a Sparkle GTX 460 1GB for use in my rig...I've put it through some benchmarking/stresstesting, and it seems to load at 64C and idle at 49C...everywhere else I have looked, it looks as though the idle should be in mid 30's. The ambient temp is about 23C - any ideas on why the high idle but regular load temp? Thanks in advance. Edit: Forgot to add in - at idle, fan speed is at 40%. Never seen it go above 51%.
