I suppose you have them in a proper colder environment?
What I can say about these cards is that they are pretty good with cooling and noise up to a certain temperature.
Past that point they fail badly while others (blower type) keep going safely.

They could be very good gaming cards, I believe. Cool and silent, exactly what you want in your gaming PC.

Yes. They are bad for high density mining but ok when properly cooled. Again, new they tend to be lower cost. If I could get a reference card at the same price I would pick the reference. As a single gaming card they work well and are quieter.

i have 2 x 7950 xfx with 2 fans, 1st that happened is that 1 fan on 1 card died, soon after 2nd died too, i bought accelero extreme and replaced cooler on that one. 1 week later , 1 fan on my other card also died, i got pissed coz i couldnt find another accelero 7970 in shops, so i sent it in service with warranty. both cards are about 3months old, and fan was at fixed 80% power.

long story short, avoid xfx cards if u dont want to buy them new coolers.

cheers

I don't agree. I have four that I mined with. Only one had bad fans, I did the online RMA and they sent fans (I did not send in card) within 9 days. These cards cost me less to buy then most, so they paid off more quickly. XFX warranty service is not super fast, but they came through for me.

Ok, so I successfully installed the new fan with a thin layer of artic silver on GPU, after cleaning it thoroughly of previous thermal paste. The fan works great only one issue, my card resets when it gets to about 70C now. Previously, I ran it at 20 intensity, and now I can only run it continuously at 11. Any ideas why this is happening? I read the artic silver has a break in time, is this what is causing the gpu to reset?? Any ideas how to fix issue?

What happens when you run at higher intensity?

You get much higher Hashrates, but it also couses more heat.
I havent seen much power draw increase with a higher intensity so it is worth to set it as high as possible, but beware, you cant really use your computer at 20...

It may also be that the cooler hasn't been secured tightly enough and it overheats because it cannot get rid of all the heat.
The cooler should be perfectly flat on the GPU. Also, the memory patches should also make contact to the cooler. They definately need proper cooling and will cause issues like you described when this is not the case.

This. It sounds like the cooler isn't quite seated properly.

Yes, Arctic Silver does have a break-in time, just like most other high performance thermal pastes.
However, that should only be good for 1 or 2 degrees celcius and usually takes about a week. It really should get some thermal cycles (couple hours on, couple hours off) during that time for optimum efficiency.

The card may have gotten a shock of static discharge while you were handling it. If you were on socks walking over carpet, it may have happened.
This often does not kill a piece of hardware instantly, but can cause it to be a little unstable at full load.

So I had the same problem with my XFX 7950( 3months old). I contacted XFX support and they offered to send me a replacement fan to do myself or send it in for them to do it. If I f-up doing myself, warranty is voided. They stated its easy, just need phillips and thermal paste. Im pretty good with tinkering in electronics. Any advice on which route to take? Can I seriously f-up this unit by just replacing the cooler? Any advice would be appreciated.

It's pretty hard to screw up a HSF install. I have been building PCs for 16+ years, though, so I'm a bit biased. Thermal paste + a screwdriver set is usually all you need, along with some isopropyl alcohol to clean off the contact surfaces. Google HSF install and I'm sure you'll find plenty examples of how they are done (it may not be on a GPU, but the concept/method is the same as a CPU).

Hello
I repaired a 7850, it only cost me U$D 20, and now is super silent, and extremely cool.
I used Arctic F8 Fans.

This is a late reply, but my advice to anyone having this problem would be to figure out a way to fix it yourself. I went the RMA route with an MSI card and ended up being down a graphics card for 6 months. Process was ridiculously slow and the first replacement they sent me was DOA.

Good luck with sale, I'm sure someone can use it.

I can second this. Had many fans fail on XFX 5870s. The RMA process is a nightmare and in the end the supplier refused to give back the cards and refunded only 40% of the original price. :S

They had only fan failures otherwise working ok. For the last few I managed to order fans, but it was a pain to get the proper ones.

Decided to auction it - seems a waste - it can still mine - maybe someone can use it

Update:

Refund came through from amazon so now I'm left with a semi working card - XFX state they don't offer manufacturers warranty (cos they sell them so cheap) and besides I have already been refunded - any ideas what to do with this card that still works with one fan?

I think the fan is failing because is the one just above the GPU and very close to radiator.
Probably due to intense heat the cheap plastic is getting softer, the axle is then not stiff enough and starts to wobble accelerating the damage.

It seems to be somehow better now that I undervolted the card (less heat).

Yes

Same issues for me, same card.
The fan near the VGA connector got almost stuck (while the other even now is still OK).
I had to lube it and for a while seemed OK but soon enough it started to wobble and got stuck again.
At a close inspection I noticed the axle was seriously eroded.

The only thing I can do is lube it periodically (and yeah, I ordered a replacement).

Yeah same fan - near the VGA connector - so you still mine with it running at a higher temp?

[EDIT] XFX support got back to me saying I should raise it with the re-seller - I told them my emails were ignored and asked whether the manufacturers guarantee will cover me - will update
