GTX 980 Overheating

[TheEpicWaffle]

Hi

I have just bought a couple of Reference 980s and both are having overheating issues.

Firstly Specs:

CPU: i5 4670K @4.2ghz

Motherboard: MSI Z87-G45 Gaming

SSD: Sandisk 512GB

PSU: Corsair CX500M

I know the power supply wont run both cards at once, there was an extra offer on the cards if you bought two so a mate is buying the second one off me.

 

So today I swapped out my old GTX760 for the 980 and thought lets see what score my shiny card gets on the heaven benchmark and almost immediately the fans ramped rut until i though I was sat in the middle of a runway and a few seconds later the screen went black and the computer went off. realising this was a overheating thing I turned the computer back on and opened MSI afterburner to see it was showing an idle temperature of about 40°C thinking this was a bit high I manually set fan speed to 80% which only cooled it down by about 2°C I then opened Project CARS and as soon as the card came out of it's low power mode the temperatures shot up to about 80°C (this was before I even got to the Main Menu)

Any Ideas

Second hand? Repaste the cards.

Defective card. Return it and save your cash for a 1070 or a RX 480. Maxwell is not worth anymore

EDIT: It's a reference card? Yeah, that's normal. Get rid of that POS PSU

80c is normal for a reference card...in fact even up to 85c is still normal....and the reason why the screen went black and the computer went off is probably because you use a cheap ass powersupply that shouldn't be used with such high-end graphics hardware.

 

Your powersupply is probably hitting it's max safe temp rating and it turn itself off to prevent from frying.

 

The nvidia card has thermal verifications and it will lower it's clockspeed in an over-heating situation, it will not shut off the computer.

1. 80°C in game fine but surely not on a loading screen for a main menu and that was just how hot I let it get before I switched it off, the temps were still rising

 

2. According to Anandtech reviews their 980 under load drew 10W less at the wall than the 760 which my power supply has powered without an issue and anyway I have since trued the card in my friends system which has a 650w corsair PSU and had the same issue.

 

3. "If the GPU temperature continues to increase despite the performance throttling, the GPU will shutdown the system to prevent damage to the graphics card." Quote from the Nvidia website, and the card clearly was thermal throttling as FPS was down at about 15 during heaven before it switched off, I didn't see the temperature so it could have been up towards the 98°C cutoff.

They are, That was the reason I bought them as it was £400 for the two, he had water blocks on them before putting the air coolers back on before sending them to me so paste was redone then but I can try that anyway
