Thermalright IFX-14 CPU and Back-side Heatpipe Cooler Review
 

The Thermalright IFX-14 uses eight heatpipes to move heat from the base plate to the cooling fins, and these pipes are larger and more numerous than on many of the other big coolers on the market. Overall it is larger than any other cooler I have had a chance to use, including some titans like the Tuniq Tower 120 and Zalman CNPS 9700, which we will see compared side-by-side in this review.
