How do you choose what heat sink is best for your system? Are you looking for something to simply give you slightly better temperatures? Maybe you're looking for something to let you increase the level of performance you can get by overclocking your processor? Or maybe you're just looking for a little peace of mind after seeing the temperatures your stock cooling solution delivers? What level of noise are you willing to put up with? How much are you willing to spend? These questions are all things to consider when looking to buy an after-market heat sink for your system. Sure you can go balls out with air cooling and buy the largest and loudest combination of 38mm thick heat pipes, high CFM fans, and a massive copper and aluminum behemoth if all you are worried about is the end result being the coolest temperatures possible. The people at the other end of the spectrum just want a good, solid cooling solution that delivers solid results with a modest cost. Will the SilenX Effizio Extreme meet the requirements of an overclocker or the person that just wants a good solid cooling solution at a modest price?The Effizio is a tower design heat sink that uses a total of five direct contact heat pipes that carry the load up to the large fin array to be dispersed by the airflow from one of SilenX's low-noise fans. With a modest asking price of under $40, the question is how will the Effizio perform against the competition with price tags that are admittedly substantially higher, but have proven performance track records? The only way to find out is to put it through its paces and come up with a performance profile for it! Let's see if this cooler provides a big bang for buck.
