Following up on our initial Clarkdale review, we decided to take a closer look at which kind of speeds to expect from using various cooling methods on the Intel Core i5 processor. Thus we have tested maximum load stable speeds with the box cooler, a custom air setup, a liquid solution and phase change cooling.As our lab in Copenhagen had no good H55 board other than the reference Intel platform, testing was done using the P55-based Asus Maximus III Formula, also cancelling out the possible use of the i5’s integrated on-die GPU.
