Radeon 4800 HD overheating (pictures)

[Fods]

mine keeps overheating when playing games (Crysis, Bad Company 2).
it take a while before it resets the computer.
I get a black screen and the monitor detects No Signal.

i was wondering if other people have been having problems with this card and how they handled it.

As you can see in the pictures i've added a fan near the graphics card to blow air away from the fan. (which as extended

the pictures don't have the door on but obviously i have the door on usually

any experience or ideas on what i could do.

ive turned on "ATI Overdrive" in the ATI Catalyst Control Center and put the fans up to 100%.

ive thought if i would need to buy a new heatsink for the graphics card?

how would i log the temperature when the computer crashes?

Get your self a copy of GPU-Z or MSI Afterburner and log some results and post back.

I don't know how to log temperatures when the computer crashes, but I do think that airflow in your case must be quite poor. Your cables are very messy which can have adverse affects on temps. Do you have any intake fans?

leave the side off and see if it crashes

This tbh. And your case is very dusty as well. Have you taken your card out and checked that it's heatsink is not clogged up with dust?

gpu-z and afterburner and rivatuner etc can all be set to record the results to a log file and then after your reboot you can check the temp just before it crashed.

ive installed GPU-Z and i will post the log on the next crash.

i didnt think there was much dirt in the computer but i gave it another once other. and cleared the GPU heatsink.

Any difference? If it still crashes as said above, leave the side off.

You could grow potatoes in the dust in hard drive cage!

LOL! that made me chuckle.

It looks like it could be the VRMs that are overheating looking at the cooling, but its hard to tell with those pics. Any chance of taking out the card and show us the cooler?
