Pros: Well made, but simple, which keeps the price down. Nice and quiet when fan runs <= 2k RPM.

Installation was a breeze for my Ivy Bridge CPU. The instructions are easy to understand. For socket 1155, it uses the 4 push pin method. Just make sure the heads of the pins are rotated opposite the arrows printed on the heads during installation. The arrows are there to tell you how to take the heatsink off.

Cons: none

Other Thoughts: On my Intel DZ77BH-55K mobo, my Intel 3770 CPU with Arctic Silver heat sink compound idles at 38 deg. C with the fan at ~1k RPM. Under the Passmark stress test, the CPU got up to 60 deg. C and held steady, even with the fan still blowing at only 1k RPM. I'm happy about this, as 60 deg. C is well within the spec of the CPU (which can safely handle up to 85 deg. C). I'd rather have the machine quiet than super cool, though my mobo lets me adjust the fans so I could make it cooler at the cost of fan noise.

Pros: Easy to install for AMD

Cons: None

Other Thoughts: Went from a stock AMD cooler on my Phenom2 975.
Lowered the idle temps by almost 10c!
Very happy with this purchase.

Pros: Quiet, efficient, inexpensive.

Cons: If you install on AMD and orient it to blow towards the back of case, be aware before you lock lever that the heatsink is centered on the processor. It can be locked down shifted off center too much. I didn't notice this, and ran it for 2 days before noticing it. No harm done. I think they need some kind of a centering indentation in the bottom of the aluminum grooves.

Other Thoughts: Running Prime 95 temps not over 51C AT 75F ambient. Llano 3870 no OC.

Pros: keeps my girlfriends computer cool on an amd phenom x4 945 idles at 28c and full load at 46c not overclocked

Cons: the extra bracket for the optional 2nd fan was broken when i received it

Other Thoughts: it works

Pros: Okay, I wrote the review below, and maybe it was a bit premature. It seems, that after having a day plus to settle and perhaps the paste to dry up some, this thing is working even better than I had hoped.

I have been watching TV and doing school work at the same time, plus have 3 other windows open and my CPU hasn't gone over 34C, and it's been at least an hour of streaming cable TV...!

Excellent heatsink for the money!!

Cons: None so far.

Other Thoughts: Excellent heatsink for the money.

Pros: I'll preface this by saying I'm not an OC'er and use my machine mostly for editing and watching video, and streaming video. While typing this and watching seinfeld , and with three tabs open, I'm averaging about 37C and I cannot hear the fan at all...!

No fan noise is a big plus because it drives me crazy, and I don't hear this one whatsoever.

Cons: Directions stink, but it's not so bad. Only took about 5 minutes to install.

Other Thoughts: My system consists of:
Phenom II X4 830
16GB RAM
Sapphire 2GB Video card
1TB HDD (7200)
Corsair PS
Win7X64

Pros: I've had this in a fresh build for almost a month now, and it keeps my CPU cool.

Smaller than the 212Plus

Good Price.

Cons: The installation was a little sketchy, as the pins didn't want to work with me very easily, but it wasn't a dealbreaker.

Pros: great airflow, not to loud

Cons: mounting hardware is a little flimsy for amd's

Pros: Quiet, seems study, easy installation, works incredibly well.

Cons: None

Other Thoughts: Took my old rig with a socket 775 P4 3.0 GHz overclocked to 3.46 GHz from running 45°C idle and up to 58°C, to 27°C idle and 35°C under load.

I worried about all the mention of finicky 775 installation and minimal instructions.... but found it to be amazingly easy and straight-forward. Installation from opening the box to turning my rig on was no more than 10 minutes.

Pros: does a very good job for the price point get a second cooler master 92mm pwm fan and your golden.

Cons: none
