Winfast px6600GT TDH Extreme fan problem

[imported_Iceberg]

I've searched all over for problems regarding this, but can't seem to find anything. Basically, it seems that my Winfast px6600GT TDH Extreme's fan slows to almost a halt, of course raising gpu temp quite a bit (I ran Half-Life 2 to see if the fan would kick in, thinking that the fan might auto-throttle, but it didn't, and the moment I saw some artifacts I exited and checked the temp of the card, which was around 76C, after which I immediately shut down). As I am writing this the fan continues to slow down, and I occasionally give it a quick flick with a finger to get it spinning again, but nothing seems to remedy.

The computer restarted twice a few seconds after booting to windows after I ran the HL2 test, and I have experienced a few other random reboots after playing Splinter Cell 2 (upon exiting the game). I'm afraid I have a defective card, but I just want to make sure it isn't something else in this brand new build. Btw, nothing is overclocked. Also all other fans are working well. I also suspect a low +12V, which Asus probe monitors at 11.776; other voltages seem ok (VCore at 1.6 - seems ok?).

Specs listed below:

ASUS A8N-SLI Deluxe
AMD FX-53
1gb crucial ram (2x512 dimms)
WD Raptor WD740GD via SATA
OCZ ModStream 520w psu
Sony DRU-710A

Shouldn't be too much hardware for a 520w to tackle, really thinking it's a defective video card...

I think its your video card. My +12V is lower than yours (11.71 according to Asus), I have a Leadtek 6600GT TDH non Extreme and yesterday I was playing HL2 running in 1024X768 with no artifacts or issues and afterward, the winfox software told me the highest it got was 76 degrees celcius. Before that it was higher in temps until I got a 120mm front case fan which has kept temps under 80 degrees since. Judging by the other components in your system, I'd say the video card is the issue.

Grrr... Next day after system build - can't even work in windows for 5 minutes without the thing auto-rebooting... I hope this issue is all due to the bad video card, I'm going to call Leadtek later today and see what they have to say. Thanks for the reply 2x... I am not using the packaged Winfast drivers or software, just Nvidia reference drivers, but that shouldn't matter, right?

I am using the official 66.93 drivers from the Nvidia site. Winfox is their system/card monitoring program that is just a plus but not necessary.
