This is a nice little budget cooler. I installed it and instantly got a 20 degree drop in idle temperatures. It works as advertised.

This cooler took me a long time to install since my bags were mislabeled. You can't just remove the old heatsink/fan and plop it down. You'll have to remove the back plate already on your motherboard. If you're not comfortable doing this, it might not be the product for you.

This CPU cooler is best installed when you're building the system. It will be a MAJOR pain in the @$$ to install afterwards since you have to remove EVERYTHING and pull the motherboard out of the case.

My best advice would be to watch an install video on Youtube so you can get an idea of what it will be like in your setup. Once I did that and threw away the instructions. This will also give you an idea of the actual size of it. It's way bigger than the pictures make it look.

My setup:

Silverstone GD05 (If you have this case and an optical drive, DO NOT BUY IT, you will most likely lose the drive bay)
Asus F1A75-M PRO
G.Skill Ripjaws memory

Pros:
* Keeps your CPU cooler than a stock cooler
* Cheap
* Quiet
* Heatsink design clears performance ram heatsink (Ripjaws etc.)
* Supports wide range of CPU/Motherboard combos
* Fits HTPC case
* Supports a larger fan if you need it

Cons:
* The instructions blow chunks, bags were mislabeled.
* This thing is bigger than it looks
* Need to remove the back plate to install

This CPU cooler fits perfectly in my mid size case(NZXT Guardian 921). It was actually a little bit larger than I thought it would be but it looks pretty mean sitting back there illuminated by the light produced by my fan. This thing works very well for my i-7 2600k processor, cooling it down very efficiently. I am not sure it will do well when it comes to overclocking though. Most people recommend liquid cooling for those situations. Very happy with my purchase!

I feel like I have had this cooler long enough to talk bout how it has performed for the last year. I have had my CPU overclocked to about 4Ghz/sec for the last 8 months or so, running high end games and other programs for writing music. I have no problem keeping my CPU cool and I even have a mid size case that doesn't have a huge amount of airflow. This cooler was cheap and still keeps my CPU at perfectly healthy operating temperatures. I still highly recommend this cooler!

I finally ran into cooling issues about a month ago. After around an hour or more of playing some games, i started getting blue screen crashes from high system temperatures. I was overclocking both my CPU and GPU SLI system. So this cooler does have a threshold. if you aren't trying to overclock everything like I am, I still would say this is a good cooler. I recently switched to a Thermaltake water 2.0 pro for my cooling needs. Its quite amazing how big the temperature differences are. Again, it took quite a lot of overclocking to finally overtake this coolers threshold.

I built a HTPC (Home Theater PC) and am running Plex, Servio, Handbrake, VLC, and various game emulators. With the stock AMD CPU Heatsink/Fan was really annoying. I cleaned the old heatsink goo off using the Antec two step removal process and then installed the new heatsink. Note: If you have an AMD FM1 the plate you need that goes under the motherboard is in the INTEL bag. The install went well and it will take a third hand to help you stabilize the cantilevered heatsink when doing the install. The install is all pictures so if you can read and follow pictures, it is easy. I had enough room in my case to rotate it away from the RAM so the RAM slots are clear and so are all of the card slots.

Idle, my temps are about 50F and when all CPUs are cranking running handbrake or transcoding a video for 15 minutes I see temps around 93F max, however even at max CPU the fan is barely audible. With the AMD cool-n-quiet at idle the fan barely spins, in fact it stops/spins/stops/spins. I am not sure why but and going to look at modifying this in the BIOS and see if I can keep the fan either spinning or not spinning, but not starting/stoppping.

If you need a low-profile quiet cooler, this should work out fairly well.

I recently purchased this from Amazon for use in a SIlverstone GD07 home theater pc case. That case has a 138mm CPU heatsink/fan height limit, which severely limits what you can use as must coolers (most are 150mm or taller). The cooler/fan arrived in great shape, but the instructions really slowed down what should have been a 5 minute install. Tiny pictures and not much text, and the hardware that was supposed to be separated into bags by type (Intel LGA 2011 vs AMD) had parts co-mingled. All that aside, once you have everything figured out the install is a breeze. Coolermaster also added some decent TIM paste in a tube that has worked well so far. The 120mm fan is pretty quiet, and is the 4pin that connects directly to the motherboard. The heatsink has a cut away so it can be directly above RAM to help cool everything down.
One good thing about this heatsink is you can rotate how it installs on to the motherboard. Because of how my HTPC case is designed, the original config would prevent using a Blu-ray drive, so I rotated the heatsink 180 degrees. Problem solved. In summary, great cooler with a decent 120mm fan that will work in a variety of cases and is adjustable.
