Can anyone offer any advice as to what else I can check before I admit defeat & bin my second GPU in 3 days.

Summary:
fitted a Kraken G10 & H55 AIO to my MSI 290. When I tried to boot up there was no signal.
My original thoughts were i'd overtightened the cooler & damaged the core.

Brought a second hand 290, tested the card first to ensure all was well (it was), so removed the reference cooler & installed the Kraken.
Booted up & ran fine. Done a little desktop work 2-3 hours, GPU idle temps around 30-32c.
Then tried to run a couple of benchmark tests to see how the card was under load.
First run crashed after a couple of mins with a black screen & load temps of 48c

Rebooted machine & tried again, this time benchmark crashed & since then I have had no signal from GPU.

Things I've checked.

Reseated GPU several times
Checked cooler fitting.
Checked all cables, including new cables from PSU to GPU
Checked DVI cable, swopped & checked with HDMI cable
Swopped PCI-e slot

Machine works fine with onboard so I'm guessing the card is dead.
But what I can't work out is why, temps were good (sub 50c)

Any suggestions would be appreciated as I'm at a bit of a loss.
 
No i didn't manage to get temps for VRMs, however the card felt cool to touch after the second crash, cooler than when the original card was running on air.

The Kraken has a 92mm fan blowing over card as well so I would have thought temps would be ok
as I've not read of anyone having major problems with temps, certianly not after only a few mins of running at load.

I've been building PC's for over 25 years so like to think I know enough not to kill two GPU's so quickly,
& installing a bracket & cooler isn't rocket science so can't see how I would get it wrong twice.

Yep the bracket has a 92mm fan on it to cool the VRM's. I haven't attached any heatsinks to them.
Looking at the NZXT website, they seem to think the fan is more than enough to keep the card cool.
