I recently installed a Kraken x31 and Kraken G10 to provide liquid cooling to my Radeon HD 7870. I have installed the driver for the cooler and made sure the bracket is well seated. I can boot normally and all use the display outputs on the GPU. The temperatures are looking excellent with an idle 24 degrees Celsius.

My problem occurs when the GPU attempts to run with any degree of stress. I will start a high-demand game or Furmark and hear a short buzz from my computer right as all display stops working. What could be causing this?

Specs: Intel i5 4670K 3.4 GHz cpu
Radeon HD 7870 2 GB gpu
32 GB G.Skill Ares RAM 2400 mhz ram
Asus z97-Pro Gamer motherboard
Samsung 850 EVO 1 TB ssd
Corsair CS550M psu

might need to play around with the tension on the screws. When I did my G10/7870, it was fine on idle too as it's barely any heat, but as soon as I would ramp it up, blue screen or drivers stopped working. I had one side torqued too much and was almost bending the bracket.

Your old heatsink might have cooled the VRM's too and the G10 isn't doing it at all. On my 7870, the vrm's are in a good enough position to be got by the cooling ram fan, so I'm good, but every brand of 7870 is different in where they choose to place things.

I would honestly think you do not have a powerful enough PSU to power both of those coolers under load so it shuts down, the kraken 10 under full load can pull up to 400watts. which is a huge amount. and your PSU I am not sure can handle it, so once the cooler has to kick in and start working the wattage goes up psu cant compensate and results in shutdown of graphics/computer.

The Kraken G10 is only a bracket, there is only one water cooler, the G31 and I doubt any water cooler pulls 400w. Where did you see that kind of funny number?

Not the exact card but using for reference Here
And yes I realize both cards have two different power draws, Sorry pretty tired and answering questions all night, still hope it helps.

Yep the sound some times means as said by the previous poster to your query.
That you have applied to much pressure to the water cooling block attached to your 7870 graphics card.
Or as said you have not tightened the screws down in the right manner to create even pressure on each corner point of the water cooling block on the graphics card.

You can damage, a Gpu chip very easy permanently by doing one or the other so have to be very careful indeed.
