I took the Accelero cooler off my 5970 because it's a crappy cooler which made the VRMs overheat, so I then put the stock cooler back on. Now the motherboard makes the "No VGA detected" series of beeps, so I put a 5850 in and connected the monitor to that so I could boot into Windows with the 5970 in the middle PCIE slot and the device manager won't detect the 5970. Yes, I did put thermal paste on all the right places on the 5970, on both the top and the bottom of the card. How could the card have died just by changing the cooler?

The 5970 fan still spins up loudly for about 2 seconds just after I do a cold boot, before going quiet again.

just bitcoin growing pains.

It is a little unclear what you have done.  I've been using 5970's for a couple of years and have had six GPUs fail out of my farm in that time (different models).

It looks like you have applied paste to the top of the GPUs, like you would with a CPU install.  Do you then attach the big, ugly heatsink?  If not, when the card starts the chips will heat very quickly and turn off (thermal trip) so you might not have killed it yet.

The back-plate is a combination of protection and heat dissipation - the HD58xx series doesn't have them.  While playing with other pieces, it's ok to leave off.

Can you confirm you have a heatsink attached/bolted to the GPUs and at least one fan running?

I would NEVER run any GPU or CPU without thermal compound and the heatsinks mounted properly, not even for a few seconds, unless it's an ancient GPU that didn't come with any cooler from the factory.

I did attach the big heatsink as well and I made sure that proper contact was made between the GPUs and the heatsink. Upon doing a cold boot, just after I push the power button to start the computer I can hear the GPU fan spin up very fast for about 2 seconds before it spins down again.




Does anyone here know if anyone will take the cooler off the card if I return it to the shop it was bought from? I'm thinking I might have to put some thermal pads between the stock heatsink and card so it looks like it hasn't been tampered with. I just don't know if the people at the shop, or if the supplier will take the cooler off and see that the thermal pads have been replaced with thermal paste making it obvious that someone has been playing around with it.

I've seen mistakes worse than that and was just checking - didn't mean to offend.  (I'm guilty of a couple really good ones over the years, especially when I was playing with electronics stuff before computers.)

The fan spinning up to max isn't necessarily a problem.  

You mention it is not being recognised in hardware/device manager.  Have you (or are you able to) plug in an extra monitor or attach a dummy plug?  Is the card detected in catalyst or afterburner?  Can you view the second/extended screen via realVNC or do you not get that far.  I think someone might have also asked what red leds come up on the back with the backing plate off.

I'll buy that Accelero cooler off you.  PM me with price.

What country do you live in?

The Accelero cooler may have killed it.
Accelero 5970 coolers have been known to damage the DVI ports and this is from properly installing the cooler using the instructions.
I was looking for something for my 5970 because the fan rattles and is really loud.
Which is another common problem with reference 5970s. 
This Accelero cooler is the only air cooler I could find but, after hearing all the problems with it I decided not to buy it.
It's a shame because the only other option is water cooling and this would cost about as much as another card.
Then again a water loop is something I have wanted to do for a while.
