Which 120mm HSF for Q6600 Overclocking?

[Kaido]

Upgrading my system and looking for a good, quiet 120mm HSF for overclocking a Q6600. I was using a 120mm Sycthe Infinity previously, which was great, but I'm using that in another build. What are the best ones to look at right now? Single or dual 120mm fans are fine, just needs to cool well and be QUIET.

Also are there any that have screws or clamps instead of that stupid plastic push-pin system?

Noctua NH-U12P
Xigmatek HDT-S1283
Thermalright ULTRA-120 Extreme
Sunbeam Core Contact Freezer 4

These are all extremely large, but should be quiet if you don't run the fan at full speed.

all the good aftermarket coolers have screws and/or clamps. intel seems to be the only company who thinks that ****ing push-pins are ok for the cooler on your expensive cpu.
