" Let's test the Frio Extreme, a huge CPU cooler from Thermaltake. It has two twin heatsinks, six heatpipes, and two 140 mm fans. We have already tested three members of this family of CPU coolers: the Frio, the Frio OCK, and the Frio Advanced. The first two are excellent coolers, but we were very disappointed with the Frio Advanced. The Frio Extreme that we are testing now seems to be the most aggressive family member. "
