I searched high and low for a Cooler for my new I7 that would fit in the Cosmos S case without taking the side fan out. This one showed up somewhere, and since it was fairly cheap while appearing to be decent quality, I bought it. It didn't disappoint.
This little thing is built extremely solid. No cheap, second grade parts. The bottom has a mirror surface, it comes with its own Thermal paste, mounting brackets for just about any CPU type, is quiet, and more than gets the job done. My CPU dropped from 55 C (With stock cooler) to an unbelievably low 26-27C (Cores run about 39)! Seriously, I would suggest you buy this product.
As a side note, I chose to use Arctic Silver 5 Thermal paste, instead of the included. Cooler Master Hyper N520 Mirror Finished Copper Base Aluminum Fins 5 Heatpipes CPU Cooler - (RR-920-N520-GP)
I love this product, it looks so nice and perform way better.
Most of all it's silent and it deliver what the manifacturer promise in bringing down I7 Extreme processor to 37degrees.
Cons:
No tools to control the fan speed nor any external switch, you will have no control over the fan speed making it not friendly if your trying to overclock your processor.
Sice of this unit is an issue, make sure you have enough size, and i mean enough size. Not only in hight i'm talking about the width of the unit, it will not allow you to install other products like DDR3 Ram because of it's size. choose mother board with more RAM slots.
I will try to upload some pictures so you will get what i mean.
Nice Cooler, very Noise Level LOW LOW!! wow i like it!!, for the price is amazing!!! i have cpu Amd Phenom x2 550 Black Edition and with my original cooler my temperatures 40°C - 42°C idle and 52°C - 54°C Full Game!!
Now with my new Cooler Master Hyper N520 my temperatures in idle is the 30°C - 33°C and full game in 40°C - 44°C is very cool :D, if i had to buy other cooler again... i buy it!!!
A+++++++ Cooler Master Hyper N520
:D
im happy! excelent Shopping!!
Before I was running Intel's stock cooler on my i7-920 and was getting temps of about 45°C at idle and as high as 80°C under load. With this, I get temps around 22°C at idle and never higher than 45°C under load. It's a great cooler. It's a little tough to install (requires you to remove the mobo from the case to put a mounting bracket underneath the CPU (don't worry, already holes in the mobo for that). But after the initial pain of installing, it's well worth it, esp for the price.
First off, if you are looking to install this, i think 3dgameman shows how to install the V8 cooler, watch this video, as the two are very similar in installation, and the instructions are useless.
Speaking of which , they actually told me to install the backplate ... backwards. This aside the cooler dropped an i5-750 from idling at 38c to 28c, using AS5 compound. Make sure you do not overtighten this sink during installation, as this will cause an imbalance and increased temps, also only use a little thermal compound, too much will ALSO increase temps.
Pros:
looks, smaller than some other heatsinks i've installed in builds, very quiet,
only my noctua's have been quieter so far, but I've tended to stick to coolers I know and trust... so not much variety (fans can always be upgraded don't forget),
price/effectiveness.,
packaging,
baseplate construction.

cons:
Fans are an odd size(if you need to replace/upgrade),
almost always requires you to remove the motherboard to install it perfectly.
Some people complain about not realizing what direction the fans blow.
ugly pin connector if you're looking for an overly clean look inside a case with a window.
First off, this thing works! It's also amazingly quiet considering the push/pull fan arrangement. This cooler is HUGE! So make sure you have room in your case before you try to shoehorn everything back into the case. Installation was a snap - BUT - you have to remove your motherboard. Ignore the other reviewers comments on a horrible installation process and take you time, laying everything out you're going to need.
As mentioned by another reviewer, ditch the included thermal paste and go with Arctic Silver.
I have an AMD Phenom II X4 955 Black edition. It ran at about 40C/60C at stock speed (3.2GHz) and cooler (in an office with AC around 72F). Now it runs around 35C/51C. I have OC'd it to 3.6GHz and it runs 40C/60C again. Not bad, not great, but for $30, not bad. If you know how to take out a motherboard, installation is easy. Otherwise, here's your chance to learn. There are bigger badder coolers out there, but this one is cheap and compact.
I recently installed an i7 860 CPU in a Biostar TH55B HD motherboard. Running Prime 95 and Real Temp showed that when fully stressed (prime 95 set for maximum heat) the CPU would rise to 85C-87C with a stock fan, no overclocking. Running the same test with the CM fan installed dropped top temp to 59C.
The problem I had is that the mboard has a small resistor right under the mboard where the fan mounting bracket goes. So I had to create some insulated washers (metal washer with plastic adhesive) to raise the bracket a bit. (Don't use rubber or plastic washers - they will compress when tightening and you either won't get a good thermal contact or the washer will compress and the bracket will hit the resistor).
The fan works great and the problem was really the mboard, not the fan.
This thing is well worth its money compared to most coolers. My systems cpu hasn't been able to hit over 35 celcius. Also just to throw this in it looks pretty sweet. When you install this tho you cannot use your stock fan mount. This one comes with a completely different one. It comes with two brackets. The bigger bracket is for most amd motherboards and the small one is for most intell. Also on the smaller one its in two pieces and the already attached bolts can be adjusted. Overall I think this is an awsome product and well worth the time and effort!! - Cpu Cooler - N520 - Cpu Coolers - Heatsink'
