GPU Reaches 70-75 Celsius and stops my PC.

[Benjamin324]

I was having a PSU problem, even in standby my PC just crashed so I replacled it with a new Corsair CX750M.But now If I don't turn my GPU Fan speed around 65-70% it will reach 70 celsius and a bit above 70 and will crash my PC like Black Screen,fans go up 100% for few seconds then I must manualy restart my PC.Any solutions?

turn the fan speeds up on the gpu or add more exhaust fans to your case.
make sure you balance the amount of intakes though. having 1 or 2 more exhaust then intake is okay but more is not.

Seems like you have a cooling problem, It's likely that the air ventilation inside your case is poor, have you tried cleaning the GPU and other components?

Please list what your setup's components are.

MOBO:ASUS P5K-VM
GPU:Sapphire Radeon HD 6790
CPU:Intel core 2 Duo E8400 3.0 Ghz
Case:Thermaltake armor revo gene
PSU:Corsair CX 750M

I have one 200mm intake fan and 2 Exhaust fans one 200mm and one 120mm

 

[Benjamin324]

Forgot to say that the intake Fan is connected directly to the PSU and the 2 exhaust fans are connected to the Motherboard.

Yep,I cleaned my components just yesterday using compressed air.

if they can be pwn controlled, go into your bios and set them to full speed.

 

[leet1337]

Based on my knowledge, which is quite limited, the only conclusion that I can make is that your PC has poor air intake and outlet.

Personally I would purchase additional fans, they are quite cheap, and practice regular cleaning of my components (Blowing your inside with a hairdryer,etc.)

 

[Benjamin324]

So guys any recommandation of fans I can purchase?
And one more thing should I connect them directly to the PSU or just to the Mobo?

70-75C under load or idle?

 

[Benjamin324]

Under load, and sorry how can I remove this solution thing I just wanted to reply?

 

[RazerZ]

Don't worry I unselected it.

That temperature range is normal for the GPU being under load. If it really is causing a problem I would suggest to replace the card's thermal paste since you cleaned out the fans/ heatsink.

I was thinking of it cause my GPU is allready 3 years old and never did that,but the bigger problem is I live in a small town and harder to get the thermal paste so I must order It any sugestions what should I buy?

The Problem is not from GPU Temp ..

 

[RazerZ]

A tube of Arctic Silver 5 should work great.

 

[Benjamin324]

Yep just tested my GPU now in Furmark when GPU got 69 Celsius the screen began to blur out and after a few secs my Monitor went black and PC crashed as always.
The strange thing is like I said before when I set my GPU's fan to 65-70% percent it just runs fine.

Are both 6 and 8 pin cables connected to the GPU? Do you have the latest drivers for it?

Yep both 6pin connected to the GPU.The latest Omega driver now released from AMD.

So any sugestions what could it be?

 

[RazerZ]

Hmm your card might have false readings... temps in the 70s should be normal under load. It's good to replace the thermal paste in any case because the paste that comes with the card is usually poorly/over applied.

Can you send me some tips how much thermal paste to apply on it or a video demonstration?
