video card fans randomly ramping up to full blast

[tviceman]

My MSI twin frozr II gtx465 has started behaving strangely over the past two or three days. It doesn't matter what I am doing, be it at the desktop, on firefox, or in a game, about once an hour the fans on the video card will suddenly ramp up to maximum speed for anywhere from a fraction of a second to a few seconds, then ramp back down to my user defined settings.

I've been in MSI afterburner when this happened, and temperatures are showing to be very normal, and the afterburner program is NOT recording the ramp up of fan speed when it occurs.

Does this happen with anyone else's video card? After this started, updated my video card drivers to the latest beta versions but it's still happening.

If fan speed is getting louder its because your GPU is getting warmer.

You should cehck your GPU temps,

Use GPU-Z to do that....

The last time that was happening to me I had to clean and re-seat the heatsink, all the exhaust channels were blocked by dust.. Both the cards exhibited idle temperatures higher by 10C than the original ones though.

Edit: If Afterburner isn't reporting the fan speed change, maybe is not reporting correctly the temperature also.

Uninstall video drivers,afterburner and ANY other gpu related monitoring software.

Reinstall just the video drivers, see if its happens again.
I think there is a program conflict.

Or mabe you just have the gtx560 upgrade bug and you need a excuse to upgrade? j/k

Seriously, it should work.
