Observations whilst swapping CPU cooler for aio.

Hi all, Just finished swapping CPU cooler ( be quiet dark rock advanced ) for an aio ( Nzxt kraken x62 ) plus a Hoover out and spring clean ( late) , made a few observations whilst doing this! To start the x62 from initial set up use has realy reduced temps well, I think?( + really cool looking) Previously at 4.4ghz temps were going heigh 90's during bench/stress testing,( stopped test at this point). Now have 4.694ghz with temps maxing at 82 during bench/stress testing, only thing stopping me going heigher is from my second observation, I have the corsair carbide 600c but because of it's inverted layout radiator has to go on the base drawing air in, this is fine but warm air is then going onto the underside of the GPU ( all fans are 140mm) so, I have two fans drawing air in at the bottom two on the front as inlet and one lower rear outlet , fine! But no exhaust above GPU, this is causing top of case to get quite warm ( hot ) the psu is at the top rear and although the top front inlet blows over the top of GPU there is also the three cooling fans on the GPU itself pointing up! Which I now have to have maxing to keep GPU under 60deg testing temp 54deg. "I could mod the back and fit another fan there but it would negate use of the bay's there, can't put one topside ( psu and drive bays there) nor the one side, only options I see is putting one in the door towards the rear�� or change the case but it does offer the piece of mind that if the aio leaks it is at least at the bottom of the board!. Another point Nzxt say to connect pump to CPU fan header but Asus say to connect water pump to water pump header on mobo ??? Have connected to CPU fan header at the minute as not sure if correct. Also should turn pump another quarter turn to the left,.65475sorry for rubbish photo.

Second one first, yes connect the pump to the CPU fan header as you did.

The description you gave of the quandary about the case cooling is the exact reason I went with the Obsidian series (in addition to the case being a bit bigger). But I wound up using a double thick radiator AIO that has push-pull fans in series instead of side by side blow like you have. You could probably go that way in your case too, allowing you to push the air out the back of the case instead of pulling the air into the bottom of the case, warming it up with the CPU heat, and then spreading that on the other components. It would probably cost you less to buy that new cooler than to buy a bigger case with better cooling characteristics. I'm not sure if Nzxt makes one in that configuration, I know Corsair does.
