Using two NF-P12s, the Havik is more efficient than the Frio and Archon but remains in a league below the Venomous X and Ultra Extreme despite their similar designs and dimensions.
With NF-P14s, it is comparable to the Archon. Unfortunately, the other two Thermalright heatsinks do not support 140mm fans, giving the Havik an advantage when it comes to quieter operation.
Again, the Havik proves to be more efficient than the Archon but not as good as the ageing Venomous X or TRUE.
In passive mode, the Havik still coped with the overclocked i7 despite the hot weather. Admittedly, I was not comfortable with the high temperatures. Without fans, it lagged behind all the other high end coolers.
