Summary: I have been carefull with it and mine is still in mint condition after years of use. This thing was big when it came out. These days there are lots of coolers that are this size and much bigger.
Pros: I love this thing. I have been using it for many years. I have it on its 4th CPU and I plan on putting it on a 5th one in the future. I have added a fan to it. Very nice to have the option to attach a fan to any of the 4 sides. Right now it is on an AMD 955 Black Edition with about a 20% overclock.
Summary: This cooler has kept my AMD Athlon 64 X2 6000+ running ROCK SOLID since 2008 even though I'm a heavy gamer & SketchUp user. Temp stays between 43C and 50C, and I live in Texas, and the wife won't put the AC above 80.
Pros: Mathematically maximized surface area, more space for airflow than most heat sinks, flow lines up with most case air patterns; installation not a big deal with a little care and following instructions; nice looks for modders
Cons: Pretty tall, fins are easily bent if you aren't careful
Summary: The idle and load temps of this passive cooler are only a few degrees lower than the stock cooler. However, considering it's silent, it's perfect for an HTPC (provided your HTPC case is large enough to accommodate it) CPU - E6700 at stock settings.
Pros: I was looking for a passive CPU cooler to put in my HTPC to reduce the noise pollution (sometimes I could hear the stock cooler over the music / videos) generated by the stock cooler. This baby serves me perfectly. All copper, and the interface already has a mirror finish to maximize it's cooling...
Cons: Installing it is a touch of a hassle; you need to remove the MB from your case to install the bottom attachment plate. The installation instructions are easy to follow, though.
Summary: I dont even know how people get their hands cut from this thing, must be noob or something in installing heatsinks(no offense). I have a Thermaltake Xaser VI and I have no problems installing. It does not interfere with anything in my case or other parts on the motherboard.
Pros: Looks nice, really quiet. You dont need to worry about that extra loud noise from the heatsink because there is no fan. Really easy to install and not as big as most people say it was. You can easily put a 80mm fan on this butterfly in any color you want.
Cons: wish it would keep the cpu cooler but thats what u get with no fan. You might want a good thermal paste because it might get warm if you have junky paste on.
Summary: There were not many reviews at the time of purchase. Should have gone with a Zalman, would have paid slightly more but worth it. Also, it comes pretty close to my ram on my mAtx board making installation difficult, I was anticipating that though.
Pros: Works slightly better than the stock cooler with my AMD 5400+ Brisbane. 3 eggs because it does run quiet enough for me (when the mobo hi-temp alarm isn't going off), and seems like solid construction.
Cons: Fails to keep my CPU under 65° while 3D gaming and intense processing. Even bought arctic silver thermal grease thinking that would solve it, didn't. Perhaps the airflow is not good enough in my case. I've tried several different air flow patterns with little difference.
Huge, sharp, not very effective and counter productive

Summary: I would just stick with a stock cooler that's far cheaper...this caused me more problems than its worth.
Pros: Keeps the processor fairly cool.
Cons: Huge, not very effective; have to worry about cables getting caught in the heat sink because it's so open. I had to tape fan cables down to the side of the case just so they wouldn't get caught and I have a massive Thermaltake Armor case that stands about 4 feet tall and is about the size of a se...
Summary: I am probably going to buy another one of these for a new system that I want to keep quiet. As long as you have some air flow in the case it works well with 65w and lower processors. The more you stress the processor the more air you'll need.
Pros: Keeps my 65w 4800+ cool enough during normal use. I really like the fact that it doesn't make a sound :)
Cons: I am not fond of the butterfly design. Wear a glove while handling it. I got cut by one of the fins on mine because I was careless during the install.
