GPU overheating ? need solution

Hello, my GPU is overheating and crashes my PC. HMonitor software shows the cpu temp rising to 105c before shutting down. It also shows that the PSU is putting out 2.6v on the 12v rail. I had replaced the previous PSU because it showed 3.66v and the GPU was doing the same thing then. All fans are working including the PSU. Not sure what the 2.6v means but I assume that it should be somewhere close to 12v. It looks like the other PSU was not bad. Any ideas on what I can check nest?

More about overheating solution
  1. We need to know the specifics of your computer. What GPU, CPU, motherboard, power supply and so forth. Thanks.
  2. Yes more specifics needed. Please add your case your using to the list above. Also let us know if the CPU and/or the GPU are overclocked.

    Can you see what your CPU temps are prior to the GPU heating up may help determine if you have a system wide cooling issue or if its just the GPU.
  3. I would recommend cooling the GPU down. That should solve the heat issue.
  4. I would definitely check your CPU settings in BIOS to ensure they are at factory specifications and still getting that hot. If they are, you might have a bad seal with the thermal paste or something, and you could try cleaning it and reapplying some thermal paste. Definitely make sure the CPU fan is clear of dust and the case is getting decent air flow. 105C is too hot for any CPU, even the new Intel's have a limit of 100C before they limit themselves. You could also try forcing the CPU to a lower speed, to see if it can help lower heat to diagnose any issue.

    Usually low voltage doesn't overheat a CPU, so while your PSU is showing low voltage, that wouldn't heat it up like that. Now, 2.6v, if it happens to be the CPU voltage somehow, is probably way the hell too high, depending on what CPU you have, which would definitely heat the sucker up to 105C easy. That's why I recommend checking your BIOS against what your CPU's manufacturer specs are.
  5. Also, since you say GPU and CPU. Some GPUs do regularly get pretty dang hot like that, I know my Radeon 4870X2 idled at like 90C before they updated the drivers. Still, you could try lowering the speed of the video card too and forcing fans to max to increase cooling. Like the others said, your system setup would be really helpful.
  6. Sorry for the limited and incorrect info in my post. What I meant to say was the gpu was overheating. I have sinced removed it and am using the onboard graphics and it is running fine except the Hmonitor still says the voltage is +2.67v on the 12v side. I guess the graphics card is bad.? Anyway here is the info from the Hmonitor.

    Theis was with the graphics card removed. The card was an HIS but don't remember the number.
  7. I put the graphics card back in and got some more info. The PC ran for about 10mins and then shut-off when the Gpu temp reached 106C. Here is the card data.

  8. If the fan on the graphics card inst dead then all I can think to do is remove the heat sink on the GPU and reapply the thermal paste.

    Or get a new graphics card.

    Funny that you should mention getting a new graphics card. Today I took the old gpu out and took it with me to microcenter to get a new gpu. Picked up a low priced G-Force card and brought it home. Decided to install the old card just to see if it still knocked the PC off in 10 mins. If you can believe this, it's been on for 2 hrs and the temp on the gpu is steady between 54-56c. Go figure. The PSU is still showing 2.54v with no shutdowns. Any ideas?
  10. Spoke too soon. Died after 2+ hrs. Just discovered that the new gpu requires 350w psu and mine is 300w. Not sure this old sys is worth anymore of my time and money.
  11. I have purchased a GeForce 8400GS but just realized that the gpu requires 350w vs the 300w I have in my machine. It says it needs 18a and the psu says it will output 19. Only have 1 HD and 2 Optical drives running on it now, San I sneak by or will I court disaster?
  12. It's like a 12 watt card, won't have to sneak by, should be completely unnoticed

    I think you are good.
    The 8400GS is powered only by the pci-e slot, and a 300w psu should be sufficient.
    Here is one link to the psu requirements which suggests 300W.

    In the event that your 300w psu is a really crappy one, the worst that wwill happenn is that it won't work, or you will get visual artifacts.
    But no harm will be done.

    Great! Tks delluser1
  15. What GPU did you pickup? A Nvidia GTX 650 should work with a 300 watt PSU. For example: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125445

    That an original Athlon 3500 from 2004? If so then Im with you about not wasting time and money on it, at least not using it as a gaming machine.

    tks to you too geofelt! That link gives a fuzzy feeling since I don't have any real knowledge of this stuff. You guys have enlightened me so much on this form that I'm thinking about going down to the Nuc Plant and asking if I can change out the rods next time. :)
