8800 ultra overheating problem

May 12, 2014 at 13:25:17
Specs: Windows 7 Ultimate 64bit, x9770 / 8gb ddr3
Hi all i installed HWMonitor and i noticed that my video card runs around 74c while doing mundane tasks like playing videos or being on the internet.

However when im playing a game it can go up to 90c and eventually it will crash the program and i have to manually close it.

Any fixes to this issue? Thanks

What is the computer name and model number?

For starters clean:
Case vents.
CPU heat-sink (without removal).
Video card heat sink if applicable.

Above not so easy if a laptop. Check temperatures afterwards and see if this improves things.

Always pop back and let us know the outcome - thanks

computer is custom built desktop.

Everything is brand new except the video card.

The video card is clean.

If temp reading are accurate and are causing the problems then either the fan is not adequate or it's not freely spinning or its air flow is partially blocked.

You also may have too many fans or fans configured incorrectly.
On cases with top mounted power supplies, use one rear exhaust fan 120mm and the power supply's fan to remove excess heat from the case. As an option, you can use one front fan blowing inward so the air blows over the hard drives and towards the graphics card. Never use side fans since they disrupt the proper flow of air through the system (in low in the front, up through the components, and out high in the rear.
If your case uses the bottom mounted power supply, reverse the power supply so it draws air from the case rather than below the case. Use one 120mm rear fan high up in the case set to exhaust. As an option, you can use a top exhaust fan 120mm or larger if needed and possible with your case and a front intake fan set low in the front. Never use a side fan as explained above.

Consider replacing the really old hot running graphics card with a cooler running modern graphics card like the GTX 750 or GTX 750 Ti of better if stronger graphics are needed and budget allows.

i already have 2 case funs running. I have a feeling that something is wrong with the video card. Maybe its too old. There is not that much dust in the fan.

"i already have 2 case funs running". Where are those two fans mounted and what size are they?

Do you have a bottom mounted power supply?

What size category is your case? Full, mid, slim, mini, micro?

I'm not sure of the size but i have one behind where the hard drives are set and one in the back next to the i/o shield.

I have a bottom mounted power supply.

My case is midsize.

If only the graphics card is running hot, then it is probably the card. Consider replacing it. If other numbers are hot as well, you need to exhaust the warm air better. Inverting the bottom power supply does remove some additional internal air and may help. If there is a top fan port, you can add a fan there blowing out which will remove the heat better since the hot air will always rise. If there is no top fan port, you can get a rear fan of the same size but higher CFM's to move more air but also watch the DB's to make sure it does not get too noisy and make sure that the rear fan is blowing out.

Is this it?


Have you pulled the cover off and cleaned it out? Even though the fan is spinning some dust might have gotten in the bearings or bushings and could be slowing it down. In that case it's best to replace the fan.

it looks exactly the same but made by evga

Unless it's always been running hot you've got to assume there's a problem with its air flow--either a failing fan or something blocking it.

"I have a bottom mounted power supply"

One of the problems with the bottom mount design is that the heat from the PSU rises. And what generally sits directly above it? Yup, the graphics card.

"Moving the power supply to the bottom of the case has several negative effects. First, it takes the power supply’ fan away from the top, so that another fan has to be used to remove case heat, adding noise. Second, it makes cable management more difficult, often times with the ATX12V cable not reaching its motherboard connector. Third, as the power supply casing warms up, it heats the graphics cards."


"i already have 2 case funs running"

I assume the front fan is an intake (blowing cool air into the case) & the rear is an exhaust (sucking warm air out of the case)? If not, that is how they should be configured.
