Summary: I am an engineer, so I have high standards even for low priced products like this. The heatsink design itself is excellent, the fan is decent quality, and the mounting mechanism is very good for the price. It is not designed to be removed and replaced so it does not have to be sophisticated. I cannot speak to the actual cooling capacity because I did not test it in a lab environment, but this is the fan system I would recommend.
Summary: This item did not do what I thought it would. I would not say that for a normal PSU that this would not preform wonderfully, but I would say that for something 4.5 ghz or more, this will not do that trick.
Summary: I purchased this in about 2006/2007 and have went through multiple processors. To this day, I am still using that very same cooler in my current build, which is a Phenom II x4 945. It's a bit cheaper than it was back when I bought it (around $35), but for the use I've gotten out of it these last 8 years or so easily have a value of at least 4x as much.
Pros: Price Performance Lifespan Aesthetic It has it all
Summary: This is probably ok for any dual core or non phenom chips but when it comes to 125W or anything close to that get something else.
Pros: Very quiet, Seems like it's made well
Cons: Won't keep my 125W Phenom 9850 cool even with better than stock thermal paste. Idles at 45C and under load goes up to 82C and hits the thermal shutdown of the CPU. No copper at all, It's all aluminum which is inferior for heat transfer/dispersion.
