Pros: It works, and it's fairly inexpensive. Quiet, too.

Cons: Way underpowered for a Prescott P4. The idle temp hovers in the mid-30s at first, but as dust and time set in, it under performs and starts to need attention. Also the fan started to make noise for a while.

Overall Review: A good cooler for the price, but why buy an average after-market cooler?
