XFC 7970 Core Edition - Idle temps....way too high?

post #1 of 8
Thread Starter 
After looking at reviews of other 7970s, it seems the idle temps are about half of what mine are



so 67C temp on a newly booted computer in a room where the ambient temps are about 20C - while Tomshardware has a reference 7970 GE at 37C http://www.tomshardware.com/reviews/radeon-hd-7970-ghz-edition-review-benchmark,3232-16.html

The weird thing is that i've been overclocking this card to 1100/1550 and the load temps seem in line

Heres my card after an hour and a half of burnin using Heaven



83C temp under load, which is about where Toms had his

Thoughts? I know the XFX Core Edition 7970s use their own cheapo non-reference boards but using reference coolers - but i got this card for $360CDN new which is a dirt cheap price for this card i believe

Also my case is the very roomy CoolerMaster HAF-X



The side panel fan sucks air in, while the 2 top fan pull air down



The CPU is a Venomous-X and i have 2 fans in pull/push config, with a 3rd fan helping exhaust the hot air out thru the back

The Tower itself is about half a foot from the wall. Dont judge my spackling there haha i have to sand/repaint the area, the desk is on the other side of the wall. Noise isnt too much of a concern for me as the tower is in a spare room.

I am getting ready to return my XFX Double-D 7970 because it was locked, couldn't over-clock past 1050MHz without the drivers crashing. Its a decent 7970, those dual fans help. From reviews, I hear blower vs fans, blowers tend to be a bit warmer. But mine at idle used to run high 40s, lo-50s.. at 1050MHz. I picked up two MSI Lightning 7970s instead and temps are better (shared load) also, do you have side mounted fans on the side panel?

In the pic there that giant fan on the side pulls cooler air into the case - targetting the GPU. There are 2 case fans on the top thats pulling air down to the CPU - theres 2 exhausts, both out the rear - one for the CPU and the other for the GPU

Almost thinking of returning this but other cards are considerably more expensive - i have a couple days while i can...

Op sorry no pictures loaded for me. Curious of the air flow in there. Because as silly as it sounds, I took a day to get my airflow correct, so air doesn't conflict. Its a smooth intake and exhaust, which after many position, turn fans, I managed to drop a few C.

are you running a single monitor . if you are then temps are very high for idle. also the two fans at the top can be used as outtake fans to draw hot air from the cabinet and vent them outside. since you have a huge fan at the side blowing cool air into the cabinet that should be enough. even if you don't have intake fans at the front of the cabinet if they have perforations in the cabinet with a filter they will allow cool air to be sucked in. see if this change helps reduce temps. if nothing works return the card.

Yup running one 27" 2760x1440p monitor 60hz, but soon to be upgrading to 120hz 1440p

I'm not sure this is an issue since the overclocked gpu/vrm temps seem to be fine - just for some reason idle temps are too high

any other thoughts? The shop i bought this from has no more 7970s reference versions in stock - i have til tomorrow to return/exchange it

return the card and get another HD 7970 card . even if its a bit more grab a custom cooler HD 7970 like the Gigabyte HD 7970 Windforce or Sapphire HD 7970 OC Dual X.
