MASTERAIR MA621PDesigned for AMD Ryzen™ Threadripper™DUAL TOWER HEATSINKS & FANSThe dual twin tower heatsink has a combination of 2 sets of heatsink towers with 2 sets of MasterFan MF120R RGB. The uniquely designed heatsink allows bigger and more spread out surface area, while the MF120R RGB fans give added air pressure from the outside and inside the heatsink to generate massive cooling performance.MORE IS BETTERAdd up to 3 fans to accelerate the air pressure and removal of heat with the 'Push and Pull'. One fan is placed at the front to pull cool air in, the second fanis placed inbetween the heatsinks, with the option to add third to maximize the heat pass-through.2X MASTERFAN MF120R RGBThe MasterFan MF120R RGB operates quietly even at high speeds. It is designed with a combination of jet engine and helicopter blades for the static air pressure you need without sacrificing airflow.EXCLUSIVE FOR AMD TR4Exact fitting base for the TR4-SP3 ensures the AMD Threadripper CPU has optimal surface contact and thus optimal heat transfer. The base also includes the Continuous Direct Contact Technology 2.0 (CDC 2.0), to have direct integration with heatpipes.MORE HEATPIPESMasterAir MA621P has 6 x heatpipes for fast transfer of heat, to make sure the CPU is running at optimal performance. Combined with the twin tower and dual fan design, you can even maximum TDP for the extreme overclockers.RGB LED ILLUMINATION(CONTROLLER INCLUDED)A wired RGB LED controller is included to personalize the RGB lighting anytime you want (no software needed). Switch it up depending on your mood, the possibilities are not limitless.QUICK AND EASY INSTALLATIONTool-free mounting kit makes installation a breeze. Exclusive for AMD TR4.
