ATI Radeon HD 5770 Cooling Problems

Hi everyone,

I'm having problems cooling my ATI Radeon HD 5770 and I think it's because the case is inadequately cooled because for some f*cked up reason my case only has one fan even though it was advertised as a gaming PC. Anyway I used Linux to crank the case fan up to max speed (4500rpm) and the GPU fan to 95% and then stressed the GPU at only 60%. Then I watch the temperature climb to 100C before I shut it down.

Here's a picture of the inside of my case:

If I put my hand under the card I can feel it blowing out warm air but it's not super hot which makes me think perhaps the stalk cooler is defective. Does anyone have any suggestions as to how I could improve the cooling on this case or does anyone know of a good aftermarket cooler for the hd 5770?

Thanks,
Mark

Try getting some compressed air and blowing the crap out of your gpu. Poor ventilation could be the culprit but you will want to be sure it isnt a dirty heat sink or something easy and cheap before buying a new case.
Also try operating it with the side of the case off. If your problem completely goes away then ventilation is the issue. If not then you know Theres an issue with the card itself then you can blow some compressed air in there and.maybe even try reapplying thermal compound

I would like to make sure it's the case and not the cooler before I buy a new $70 case

^^ try my suggestions Then report back primarily taking the side of.the case off to see if it is a ventilation issue and immediately rule out whether its the case or gpu

Then its the card. Now you can rest easy that it isnt the case.
Try blowing the dust out and if that doesnt work you may need to try to reapply the thermal compound

Op needs to clean it before he reseats the cooler with thernal compound before he goes and buys a 45 dollar fan
OP ; try the cleaning first and lets see Whats the deal after

Oh I totally agree with you 100%. I thought you made that clear to the OP before I linked OP to the type of fan's he was asking about.

Nah he has tried taking the case door off to no avail so we know it isnt a ventilation issue.
Besides, that card is reference and exhausts the hot air outside and.is perfect for his situation. Theres a side vent that will provide enough flow for his gpu

Also in that picture it looks like op has a mount for a front intake fan.which.would be a good idea to install as well as try and get rid of that worthless cone on your cpu heatsink if its doable.
With a front intake and that side vent you should have plenty of flow.over your system
