7970 Manufacturer's specs for max temp?

post #1 of 12
Thread Starter 
I've been trying to figure out the maximum safe temp for my XFX 7970 Double D Black Edition. The posts I see about 7970 temps are people saying things like “I like to keep mine under X temp” or “You’ll be safe it you keep it under X-ish temp” but as far as I can tell these numbers aren’t really based on facts from the manufacturer, so they’re really just guesses.
Does anyone know the manufacturer’s official maximum temp for XFX 7970s or any other 7970?

Thanks!

AMD announced on Facebook that the maximum temperature is 85*C on the core, unknown on the VRM's. But Tahiti losses overclockability past 70*C, this will un stabilize your overclock

Keep it under 85C and you'll be fine. TJMAX for the 7970 is about 90-95C but anything over 85C is pretty hot water.

Great, thanks.
With my fans on auto it will go above 90 well before the fans ramp up to 100%. Kinda strange. I'm kind of looking for an excuse to use a different hsf anyway!

I wouldn't set it to Auto if it gets that hot. I'd manually set it to about 70% and see what stress testing and gaming is like then. But keep it under 85 (80 preferably).

Download MSI AfterBurner, it will let you set a custom fan curve, so when it hits 75*C for example, it will ramp up to 100% etc

XFX is known for applying alot of TIM to the GPU. It may be the problem, but it'll void your warranty if you remove the cooler, as there are "Warranty void if removed" stickers in the screws.

All AIBs put on too much tim. The stickers are for countries outside of North America where the Modder's Warranty does not apply. XFX are actually not the first company to do this. Powercolor was first with their hidden warranty voiding serial number sticker on their 6990. That one was devious. If you went to put on a waterblock or remove the cooler, you had to remove the serial number sticker to get to the screws. Then bam, you tore the serial sticker and it's double sided, inside it say warranty void. Haha, lol. Not nice.

My PowerColor has the screws revealed, does this normally apply to 7xxx too?

I don't think they did it with the 7xxx. MSI does it with the 7xxx like XFX. But in most cases if you contact support and have a valid reason they will allow you to replace the tim w/o issue.
