Picking The Right Cooler For Haswell
After hearing about 5 GHz overclocks from pre-production fourth-generation Core processors (that's Haswell, for fans of code names), enthusiasts were despondent to hear that retail parts would be far less friendly. Angelini even went so far as to poll folks with hundreds of retail processors for his launch coverage in The Core i7-4770K Review: Haswell Is Faster; Desktop Enthusiasts Yawn. The consensus was that stability at 4.5 and 4.6 GHz on air was extremely rare, that most enthusiasts should expect to top out at 4.3 GHz or less using 1.2 V, and that heat is the most likely culprit.
Before we get into the details, let's have a quick look at the nine air coolers we'll be testing in today's round-up.
