Windows 7: Nvidia driver 'pegs' fan 100%. 620 GT

Nvidia driver 'pegs' fan 100%. 620 GT

gang how do I stop this annoyance? have a EVGA Geforce 620 GT card in a DC7900. card is nice and quiet like my evga 630 gt in an identical system, UNTIL windows fully loads up and the NVIDIA driver kicks in. fan goes bonkers - wide-open and its not pleasant. remove the driver... all is well.

how to get a grip on this? is it just THIS particular rev of the Geforce package [latest/greatest]? if I start randomly backrevving will I find one that works properly?
Again, I have the sibling card, 630 version in an IDENTICAL DC7900... no issues. works great

i'm stumped.
it also disappears my buitlin ADI audio device but I think I can manage that by stick-handling the bios. we'll see. the evga 630 card is smarter and steps around the ADI device; not ON it.

thx

Hi zapp22,

I suppose you could install a program such as MSI Afterburner and use it to set a custom fan profile for the GPU. You can also tick a tab to get the Afterburner to start with Windows.

Have you checked the temps on the 620 GT? Usually fans only ramp up to 100% if the card is roasting hot but I can't imagine it being hot as soon as Windows starts.

I did that but, as others in other posts/threads have noted, no matter what I tweak, the result is the same. MSI-A reports the nominal spin as being 65% of max - I cannot vouch for that but apparently that metric 'stuck' in the minds of others also who have tried to ratchet down the volume a bit.
What's so irritating is that the fan loafs along quietly under every other circumstance EXCEPT when the Nvidia drivers kick in. I doubt that the reference spec really nitpicks the choice of heatsink & fan so it is somehow electrically possible to get this under control. how? I dunno yet.

like I said, i have a EVGA 630GT card also - no problemo with that one. it loafs noiselessly until you put it to heavy lifting

I assume you are using the latest Nvidia drivers? Have you tried uninstalling and using some older ones?

Could poor case air flow be part of the problem.

I'm thinking that the real issue is that the fan itself is noisy - if it would rotate at something like 30% it would have a tone that isn't so noticeable - probably the fan isnt going to have a long life. when I put a finger on the top edge of the card it has a real noticeable vibe to it. maybe its just unfortunatel mold so that it is out of balance, or maybe bearings.

the case is spotless, and as said before is identical to the one i have the sister 630 card in.

You should not feel that vibration in your video card. The only thing that moves on the video card is the fan.

I have used MSI Afterburner for a good while now and I advise you to go into the settings then click the Fan tab and set your own Fan curve. Then make sure you've checked the box at the top above the fan curve that says "Enable user defined software automatic fan control", this should then set the fan speed to whatever you want versus temperature.

I had to enable it because the default NVIDIA driver Fan curve didn't increase the fan speed much compared to temperature rise. I figured the fans were easier replaced and cheaper than the whole card.
