Pros: Easy installation, super quiet, MUST HAVE

Cons: Sharp fins but that's it

Other Thoughts: I recently bought this not even 2 days ago, lightening fast shipping came here in one day. Cooled my CPU from 50C to the late 20s mid 30s. I recommend this fan for gamers.

Pros: No LED and PWM. Sometimes yoiu just want a cooler that doesn't glow in the dark.

Cons: They don't make their 120 and 135 PWM versions without LEDs.

Other Thoughts: I've used a number of these coolers for 775, 1156, and 1155 builds. Never had an issue with installation or chip cooling. They are large, so make sure you have enough room in your case. You may have to remove the side or top panel cooling chute to get clearance. I usually do that anyway and put in an 80mm fan, when I have room, just to get a little more air on the fins.

Pros: Keeps my processor cool, cool, cool. Looks great too.

Cons: Will make you bleed.

I swore after reading many others' accounts of injury due to the sharp edges of this heat sink that I was much too coordinated to have to worry about cutting my knuckles on this component.

I was wrong. This heatsink is essentially 100 copper razor blades welded together. On the upside, I feel a much closer bond to my rig after shedding blood in its construction.

I'd buy this again, but please handle with care!

Pros: Great CPU fan, keeps everything cool for a great price

Cons: None Yet

Other Thoughts: When installing this CPU fan, there is a tension rod that you have to screw down. It will be very tight and I thought I was going to break my CPU. I went ahead anyway and nothing bad has happened. Make sure to use plenty of thermal grease, as always.

Pros: cools well , looks great

Cons: a little hard to install, but with patience it is worth the trouble.

Pros: 1. Lowered my 42.GHz OC'd i5-760 load temperature from 73C~75C to 64~68C
2. Stable and quiet (usually)
3. Has its own thermal paste
4. Affordable price imo

Cons: 1. Hard to install - likely to get cut while fastening the clip screws
2. On full load when temp goes over 60C, it becomes pretty loud. With another loud GTX 480 fan and room temp being 75F or more these days, speechless.

Pros: It keeps my CPU cool, and the fan is not loud as some people claim it to be.

Cons: When Unpackaging, I obtained different componets, for example:
Clip Support
Clip Support Fixing Bolts
Clip
I have a Z77 Asus Sabretooth with thermal armor, so the clip support was a bit tricky to install because it has a lever slot, so I had to install in a way that it could fit into my motherboard.

Other Thoughts: Good fan.
