The Swiftech Apogee™ SKF LT is a universal CPU waterblock featuring Swiftech's revolutionary Skived Fins "SKF" cooling engine and built-in Addressable RGB LED lighting, fully compatible with Swiftech's IRIS. The SKF cooling engine is made of 125 micron (< 5 thousandth's of an inch!) thick slotted fins! This new technology is at the very least one generation ahead of the competition and is the foundation of Swiftech’s current CPU waterblocks. With only minor effect on pressure drop, this technology yields up to a few degrees in CPU temperature which is substantial for more gamers, overclockers and enthusiasts alike.
