Summary: Fit really well on my Gigabyte z68xp-ud3. The only real negative I can think of is the mounting system. Yes it made mounting the cooler extremely easy, but I'd rather have screws holding down the plate than a little plastic bracket push pin.
Pros: Silent Very easy to install Good cooling (45 degree under load, stock setting) Great value
Cons: Stock Intel brackets, though easy to install, are not as stable, break easily, and hard to confirm sometimes if they are installed correctly.
Summary: All in all I am pretty happy with this cooler. Just built a new rig 45 days ago. Goals were: Reliable (most important), fast, good bang for the buck, 16 gb RAM, silent and all able to run on a 500 watts PSU.
Pros: Silent. Good cooling. Thermaltek brand. Long warranty. Affordable. Relatively small. Fits well on a p8p67 system with 16 gb of ram (using all 4 dimms).
Cons: Not that much better in cooling than stock fan - However, WAY less noisy than stock.
Summary: It keeps my i7 870 bellow 35 at all times
Pros: -Works well -Not so big -VERY easy to assemble -great for first-timers -cools well for what it costs
Cons: -only OK cooling, don't expect to do any CRAZY OCs with this fan. I'd recommend it to someone who wants either swappable CPUs, or running a MILD OC. -the included thermal paste.... just get arctic 5 already
