Let me tell you a little bit of my set up. The case Im using is NZXT manta. Ek waterblock with i7700k. Evga 1080 hydrocopper. I have 2x 240 rad. Front rad is pulling air in and top rad is pushing air out. No over clock what so ever. With the top of case close Im hitting 67° max, with it open its getting 55° max. A friend of mine is saying the front should be a exhaust too, so I don't take in hot air. My cpu temp checking with bios is saying 5-10° hotter then GPU, is this normal? Now my front intake fan is a case fan and not a SP fan. Don't know if this will make a BIG difference?
