first time watercooling bad pixelation

[NIBSWORLD]

Hi Guys
Im looking for some help
this is the first time im using a watercooling kit
http://www.overclockers.co.uk/showproduct.php?prodid=WC-042-OE&tool=5
i have it set up to go from reservoir/pump , radiator , cpu ,gpu back to reservoir
im using a Radeon 7990
when i run ungine heaven i get temps about 50c but after playing battlefield 4 for about an hour my system is blowing out really hot air from the top of my case "coolermaster cosmos II" and im getting bad pixelation on the screen i have a push pull config on the rad im just wondering if i need to reset the block on the gpu or try ang get a thicker radiator but the case wont fit anything thicker than im using so i might have to get the corsair 900d if the rad is the problem
any help would be great
Thanks

PIxelation isnt good mate so Id be worried you have fit the block right but in my book that rad isnt big enough for your whole rig

Like Tom said, that thin 360mm rad will struggle to keep a CPU and 2 GPUs cool at the best of times, so you couldn't expect good temps in the first place.

Pixelation certainly isn't a good sign, and might indicate that something hasn't been done properly mounting the block. I'd consider reseating the GPU block, and ensuring that no paste or pads have got on anything they shouldn't have.

Cheers for the reply's
what rad will do the job i think i can only use 360 any suggestion
i stripped the machine down the othere night and re fitted the water block on the 7990 temps have come down abit but still getting extremely hot after an hour or so on battlefield 4
i ran ungine heaven last night for an hour and it only got to max at 52c

hope i can get this problem sorted cause i realy like the way my system looks now dont want to go back on air

any help would be great
Thanks NIBSWORLD
