GPU Temp Question!

[Laytonoid]

Hi there! I have a Asus ROG MARS 760. This card has two 760's on a single PCB. Its kind of like a GTX 690 kind of card. 1 of the GPU's runs at 79C max. The first one runs at 90C sometimes! Never above that though. This card has a max operating temp of 125C and can run at 105C for 10k hours. This info is provided by Asus so who knows if its just some marketing scheme. Question is.. would 90C damage my GPU in any way? I have a fan speed of 65% on load. Let me know what you think.

I think 90C is way too hot. I'd up the fan speed.

You should only get that sort of temp if you're stress testing it eg Furmark, Kombustor. Even 79C is getting up there. Especially when you consider the reputation Asus has for having good gpu coolers.

You haven't upped voltages or anything have you?

i7 is right,90c+ is far too hot!
Time to make a custom fan profile with a program like EVGA Precision X or MSI Afterburner. I personally like Afterburner,Precision X has a ridiculously large GUI that you cant do much with.

Well its suppose to run at 105C for 10k hours.. so even if I played a game for 5 hours a day at that temp.. It wouldn't break til then.. so shouldn't be ok for 90C? How fast is to fast for fans? will they break?

90C under full load is not too bad, but id watch that very very closely. anything over 80 is a bit concerning, but while operating is safe at 90C i wouldnt want it hanging around that for more than a minute at a time. if thats at idle, then imagine how hot it is under stress load. If that IS under a huge load, i wouldnt worry all too much, but tdo what you can to increase cooling (make sure fans hit 100% at lower temps to prevent it).

..the silicon is rated to withstand that amount of heat without breaking down,its not a temp you want to maintain.

For comparison;I dont like my GPU's going over 75c

 

[Laytonoid]

The GTX MARS is suppose to be able to go over 20C of normal GTX cards. Whatever that is.

No..Silicon is silicon is silicon.
Marketing hype might say one degree while another company says a higher degree,but in the end its all silicon.

Can you post a link to that 'run at 105C for 10k hours'?

They are probably talking about core temp - which is about 25C higher than case/package temp.

Maybe your measurements are core temps too. The we can all relax.

Can you provide screenshots so we can see temps, fan rpm and voltages, etc?

I used precision X and also MSI afterburner to check temps. Idk how to attach a screenshot on here. But theres the website.. its the stuff off the asus site. idk where it is on the asus site. But yeah, operating temp of 105 for 10k hours. So thats like 5 years of playing everyday for 4 or 5 hours at 105C.

a 12-phase power design and comes with Japanese-made black metallic capacitors that should offer 20%-better temperature endurance for a lifespan.

So the caps can withstand 125c temps for 10k hours...Good thing the caps wont ever hit that temp before the Core does(and then cooks itself)

That link - http://www.guru3d.com/articles_pages/asus_geforce_gtx_760_mars_review,9.html

shows stress testing only at 75C max on the gpu but 82C on the vrm

ASs we've said, you shouldn't get anywhere near that while gaming. Idle will be a touch above room temp.
