Ok when gaming, my video card severely overheats. I mean within 5 minutes it reaches 100°C. It sits at 55°C at idle or when doing things like surfing the internet. ALso, when I alt-tab out of the game to check the temp, I can see the temp slowly dropping but as soon as I go back to the game, the temp goes back up. It happens with all games.
Recently, I had an 8800gt fry. I was playing Battlestations Pacific and didnt think to check temps because I have never ever had a temp problem before. Then I started getting artifacts and bam, the computer shuts off. I smell something burning so I open the case and check. I pull out the video card and it was hot, so hot i burned my fingers on it. I took the card to a friends house and put it in his comp but no joy, it was fried so I installed a 7800gt that I had laying around.
Im really at a loss here. It only overheats when gaming and when you alt-tab out, the temp starts dropping to normal levels but if you go back to the game, the temp starts to rise again.
The system ( warning its old) :
ASUS A8N32-SLI-Deluxe Mobo
Athlon 64 X2 4800+ @2400mhz
2gigs of RAM GSkill PC3200
PNY 7800GT 256meg using nvidia 181.72 drivers
O/S is Windows 7 and I formatted and put XP Pro SP3 on and the problem persisted.
Power Supply is an Antec Truepower 2.0 430watt
Using ASUS PROBE, the voltages that are showing while a game is running are
+3.3 : 3.33v
+5: 4.95v
+12: 11.97v
Oh I also took the side off of the case and sat it near an AC floor duct and set a fan near it to blow the cool air into the case and it still overheated. I also took off the heatsink from the vid card and slapped on some Arctic Silver and then reinstalled the heat sink. The case and fans are dust free. Once a week I use canned air to blow out the dust.
I hope someone has an idea. Im kinda thinking the mobo is on its way out but I was hoping it would wait til July when I can build a new system.
Anywho, thanks for any help/advice you guys can give.
Usual culprit is fan speed but assuming your compy doesn't load special profiles for your card in just your system, there's no reason fan speed would vary between systems. In any case, I suggest you set your future cards to run fan speeds as high as they can in the future, and log the temps while you're full screened in a game; then slowly back them down till they get above a comfortable temperature for you to have in your system. If for some reason you're getting high temps with no side panel, AC blowing, and max fan speeds you have a serious issue on hand (and I'd doubt its the psu since with voltage irregularities that high the rest of your system should have noticeable changes in performance/temps if not an auto-shutdown to preserve the parts).
