Nvidia fan speed question

I have an EVGA 9800GTX+ running the latest 185.85 drivers on Vista Home Premium 64bit. However the fan speed never seems to changes and always stays on a low speed, even when I'm playing games and the GPU temperature rises from 32c at idol to 65c within mintues of loading up the game.

My question is should the fan speed be automatically controlled to run faster as the temperature rises?

The fan runs quite loud in BIOS until Windows boot up then goes to slowest fan speed. Are there any BIOS settings that'll let the BIOS control the fan speed instead of Windows? (Motherboard is Asus P5Q Pro).

I've installed Nvidia nTune so I can set the speed manually, but this software doesn't seem to work well at all as it won't let me save a device rule in the device profile and seems to activate a profile policy without meeting the rules criteria (I set a profile to run GPU Cooling at 100% when GPU temperature was higher than 60c, activated the rule when the temperature was around 35c and it immediately set the fan running at 100%!).

Any help much appreciated. Thanks.
 
hi,

u can use evga precision to control the fan speed if ur having trouble, u can save up to 10 profiles and u can select them easily.

sorry i do not no of a program that can control it automatically withe these drivers

The reason the fan is not spinning up is that it doesn't need to.

60*C is nothing i used to run on of my 8800gtxs at 90*C 24/7.
GUPs are designed to work well above those temepratures, you really have nothing to gain from upping the fan speed other than more noise!
GPUs are generally setup to throttle back at 105*C and shut down at about 120*C. So you can see you are well within the thermal design. Just leave it as it is, less hassle that way. Unless you've set it manually, the fan speed will increase as and when needed andther is far less noise if you just leave it to its own devices.

Dunno about a 9800, but on a GTX260, the fan on auto won't start to increase in speed until the GPU reaches just over 70 degrees.
