High temp with x-flow radiator

[Ticonderoga]

I’m running the following system at 4.1 ghz :


Intel I7 970

Asus rampage extreme III

Zotac GTX680

Custom watercooling with a HW-Labs black ice GTS 360 Xflow radiator, EK GPU acetal block, XSPC Delta V3 CPU block and Phobya DC12-400 pump+ EK-Reservoir Combo DCP 4.0.

The cpu reaches temps of 65-67 under load and the gpu around 55-56. Problem is that my old Antec 620 was able to cool my cpu better than my current setup. I tried reseating the cpu block and applying new thermal paste, but no difference.
So I think the problem might be with the fans and radiator. It is a high fin density rad and I am using 3 yate loon D12SL-12 fans. Will changing fans give me any noticable difference in temps?

both gpu and cpu on and only 1 rad? That might be the problem, I am too running only 1 360 rad to cool 680 and 3570 and my cpu temperatures are same / worse than on air.

I am not certain but I'd say adding another rad in there would help, otherwise what you go is what you is normal.

Seen as my temps are not that good I just put fans on off and 800rpm if cpu reaches more than 55c. The rig is dead quiet.
