Swiftech introduced a limited-edition variant of its Apogee SKF series CPU water blocks, the Apogee SKF-TR4, which is designed for AMD Ryzen Threadripper HEDT processors. The blocks come with an elongation for better coverage of the large Ryzen Threadripper integrated heatspreader (IHS). The copper blocks are longer than the original SKF Heirloom series blocks, and feature more micro-fins, translating into 30 percent more surface-area for heat-dissipation to the coolant. The blocks also feature a coolant fitting positioning such that the inlets and outlets are directly above the two active dies of the Threadripper multi-chip module (MCM). The factory-fitted retention module only supports AMD socket TR4/SP3r2 motherboards. The block is priced at USD $107.95.
