Pros: The fan and heat sink work great. Keeps the processor I got running cool.

Cons: There is no instructions and you may become confused installing it.
It is also very big. This may or may not fit in your case.

Other Thoughts: Great product so far.

Pros: The main reason why i bought this one is because the heatsink is HUGE. The 120mm fan pulls away a majority of the heat which is then sucked out of my case by my external fan. The blue lights are a nice touch. Overall, this is a very nice heatsink + fan especially for the low price.

Cons: Although, after about three months the fan started to have problems. It works like an old car and needs time to warm up before it will actually start to spin. The warm up time takes close to 2 minutes. Even after that, the fan seems sluggish and occasionally will makes noises as if something wasn't aligned correctly.

Other Thoughts: Like i stated in the title, this was an awesome CPU cooler until the fan died. Replacing the fan is an extreme inconvenience as i have to take out my motherboard from the case and remove the heatsink (which took forever to put in) in order to get to the screws to remove the fan.

Pros: This thing is a monster. I have yet to get the computer running yet (either memory or mobo video is bad) but this thing will def. keep my phenom II cool when i overclock it. Easy to install. Cant wait to see how cool it keeps everything. above all it is quiet, super quiet.

Cons: because of its size and my choice to run a micro atx i cannot upgrade it to the two fans since it will cover the first two dimm slots. other than that nothing. make sure it will fit in your case. my case is a coolermaster cm690 and it fits nicely.

Pros: this heat-sink is absolutely incredible!

i have a phenom x3 720 (with unlocked 4th core) 2.8 ghz overclocked to 3.8 ghz. the idle temperatures are 33 C and full load is 38 C

the cpu never goes above 40 C even after extreme overclocking.... this thing is incredible

Cons: The Fan is a little loud, but its worth the amazing cooling
the blue lights are more purple

Pros: Best cpu cooler I ever owned,running a e7400 core2duo overclocked from 2.8Ghz to 3.8Ghz and ideals at 28c never gets above 52c under load.

Cons: None

Other Thoughts: Antec 900 case barely fits-Big CPU cooler but I am sure you already realise that.

Pros: The installation provides a secure mounting to the processor chip compare to others that use a mounting system similar to the OEM heat sink. The size and weight require more than OEM style plastic snaps, The placement of the fan also provides a clean air flow over the memory modules and directs the heated air to the rear of the case for the case fan to remove.

Cons: None

Other Thoughts: I previously had an ASUS Triton 85 installed in this system and the mounting snaps came loose causing the system to power off on a thermal. Why they came unsnapped is not known, but is unacceptable.

Pros: Price was right at the time. Included fan looks nice, moves a lot of air, and is quiet. Able to overclock my Q9300 to 3.34GHz at 1.4v (It was stubborn!) with this.

Cons: None that I can think of

Other Thoughts: Bit outdated now, a year ago it was great. Can get a Scythe Mugen 2 for $36 which is the better deal if you have the case for it.

Pros: So far this baby is keeping my AMD Phenom II X3 ,that has all four cores opened and overclocked from 2.8ghz to 3.6ghz, cool and happy. When my room is at 80+ degrees F, it keeps it at a mere 43 degrees C at idle and it goes up to 50+ maybe 3 degrees more at full load. Currently it is 76 degrees F within my room and my CPU is running at a cool 28 degrees C. That is at idle. I do keep my fan running at 100% and it isn't that loud. Of course i have a Cooler Master case that has sound dampening to help with any loud noises.

Cons: No Con's so far, except it's a pain to put onto the motherboard if you've never put on anything but the stock fans before.

Other Thoughts: I suggest just a very light coating of thermal grease for the optimal conductivity and that you take your time to read the directions. All in all it's a very good cooler. It also has a very nice blue light, of which I'm picking up it's sisters this week from UPS to replace my stock fans in my case.

Pros: I got E6750 (Duo 2.66Ghz)
For comparison:
Arctic 7 Pro 92mm
Cpu Speed Idle Load
@2.66(stock) 32C 55C
@3.0 35C 60C
@3.2 36C 61C
@3.4 the temp started going up till 70C and raising.
I stopped the test as there was no point in seeing how high will the temp reach b4 PC shutdown

Hyper 212
Speed: Idle Load
@3.2 33C 54C
@3.4 34C 54C
unable to oc anymore, yet :)
All load test done with Large FTTs setting on prime95v259 for 1hour.
As you see the hyper performed a lot better and its only about ten bucks more.

Cons: Had to take out side fan from my Xcilo Full tower the 360mm and replace it with 2x120mm. I gained few deg on the 9800gtx's because of it, no biggie.

Other Thoughts: I didnt install a 2nd fan on it, will do when i get a quad core.
easy install, there is a manual but you dont really need it]
Overall im happy with the purchase.

Pros: Very well designed
Easy to install
Runs cool
Quiet-ish

Cons: Huge, make sure your case will accommodate this heatsink!
