I would not get the a70 cooler over the coolermaster 212or 212+, the a70 has a iffy 1155 mounting system and has8mm heatpipes,plus it's much bigger overall.
The CM 212 has 6 mm heatpipes,comes with a extra fan bracket to do push pull.
Believe it or not the 6mm heatpipes work better then the 8s,
less pipe to heat up so it transfers heat faster from CPU to fins
Plus it will run about 5c cooler then the a70
bigger is not always better,even more so since your cooling a 95watt CPU not a 130 watt CPU.
Is this something to worry about?
1. The CAFA70 has 3 pins.
Don't know if the ASUS P8Z68-V PRO can speed regulate a 3 pin - any idea?
2. It also seems that the ASUS P8Z68-V PRO expects a 4 pin CPU fan in its POST routine (NO idea if they fixed the firmware):
both will fit, I have the Antec 300 Illusion and once had a hyper 212+ but had to temporarily switch cases.
I had to switch to a lower profile cooler and just kept it on there now.
also you can add a second fan to the hyper 212+ just like the a70..
