Thermaltake BigTyp 14 Pro CPU Cooler Review
 

The Thermaltake promotional material claims the BigTyp 14 Pro is "completely silent", which just isn't true at any speed with the included fan. Despite this, I was quite pleased with the performance and noise level at the lowest speed setting. When I switched the stock fan out for a 92mm fan mounted under the cooling fins (blowing upward) things got even better.
