Faulty 7970 Fan?

post #1 of 7
Thread Starter 
I have 2 7970's and one of them has an issue with one or both of the fans. (Each card is a dual fan design).

OK, Here is the issue. The card in question will present an electrical sound from one or both fans when the speed is between 55 to 67 %.

I have taken a look at removing the fans and shroud but you need to remove the whole cooler, then use specialist tools to open the shroud.

I have had this card for 10 days short of a year.

If I RMA, I will have to buy another card as powercolor and the retailer will not supply a replacement of the same card version because it's discontinued. The only card I would be able to afford is this:
http://www.ebuyer.com/480139-radeon-hd-7970-3gb-gddr5-pci-e-2xdvi-hdmi-dp-oc-w-11197-03-40g

The question is, will this card work with my current 7970?
The sapphire card runs at 950MHz (1000MHz Boost) and my current card/s runs at 925MHz, on the core.

Also, how long is my warranty and how do UK customers RMA via powercolor? I've heard from people that EU get no warranty cover by powercolor.

Here are my current cards:

Thanks for the help!

if i were you i would just go custom cooling. watercool just one gpu for now if you want (one on the first pcie slot). replace that broken fan . . .

i saw your earlier thread where you inquired about watercooling these 7970s.

This is not a viable option for me. Sorry.


This fan will not work.

Any card from 79xx series will work with your current card. ANY. Be it Powercolor, Gigabyte, Asus, etc. If you want them to be at the same stock speeds, why not simply overclock the lower clocked one? Is easy as hell. Better yet, overclock both your cards to higher stable clocks and enjoy wink.gif

there is an option to synchronize multi-gpus in Trixx and AB. I never used it but, like i said, i never experienced any of the problems you are concerned about. Also, i am not sure if CCC has one. it might.



if ever you use it, i'd suggest try it first with both gpus at their stock settings. these apps might conflict with games i read.

What about the difference in VRAM timings?
