Bad GPU temp sensors? And cooling mod

post #1 of 3
Thread Starter 
Alright, I have a Nvidea GeForce 9800GT by pny, the card has always ran hot (60-90c), and it even overheated once and we got a new one through warranty. I do not quite remember all the temps from before. But on the second card I got, the one tiny little fan used to cool it started to die, pny has never done anything good, so I took matters into my own hands and just replaced the fan. I used an old fan I had lying around, but it does connect to a 4 pin molex now instead of the card itself. The card ran fine for a while, and I just left it, stopped checking temps and everything. Recently I checked the temps and it would IDLE at 80-90c and under load I saw it hit 115c. the moment It hit, I shut the computer down. Now I don't know for sure, but shouldn't 115c break the card? This card has ALWAYS run hot, which leads me to believe it could be a bad temp sensor. Do you think that could be possible?

I took the card out and took it apart. Took the plastic piece covering the whole card off (that's a lot of 'Tooks'!), then took the heatsink off of that. I Dremeled a nice square hole right above the heatsink and stuck another heatsink on top of that with thermal paste and everything. I then added 2 more fans, one on the end, blowing air into the intake, and another ontop of the heatsink blowing towards it. I also added a pci slot fan to blow all the air put out by the small fan out of the case. The card now idles at 60, and I've only seen it get near 100c. Either way this is extremely hot, and I'm really wondering if it could be bad sensors or if this card is just HOT AS HELL. Any thoughts?

If you'd like the see the card I can post some pics

I used to have a single slot 8800 and it would get to 90C before winding the fans up. All I did was flash an overclock BIOS (that I made) with custom fan profile. I got my temps down to 60C max and a 24% overclock. Not too bad for just a BIOS mod.
