This kit includes the Watercool HEATKILLER IV PRO CPU Water Block and the Thermal Grizzly KryoSheet suitable for the AMD AM5 socket. Water coolers from the HEATKILLER CPU series are among the most popular and top-selling CPU water coolers. Ever since the launch of the first HEATKILLER CPU water cooler in 2001, the series has been constantly improved and optimised. The HEATKILLER IV presents the most extensive alterations, so far. The focus of innovation was the new cooling structure. Finer micro fins greatly enlarge the contact surface of cooling liquid and cooler. Flow characteristics became optimised as well. These changes increased the cooling performance by up to 3 degree C compared to the predecessor. Specifications: Material: ACETAL (top), nickel-plated copper (bottom plate), polished stainless steel (brackets), nickel-plated brass ( Easy-Mount-System) Dimensions (L x W x H): 66 x 59 x 17 mm Weight: ca. 450 g Sealing: NBR 70 Threads: 2x G1/4 inch (DIN ISO 228-1) Thread distance: 25 mm Socket compatibility AMD 939, 940, AM2, AM2+, AM3, AM3+, FM2, FM2+, AM4, AM5 The graphene thermal pads of the Thermal Grizzly KryoSheet series can be used as an excellent alternative for thermal compounds from the higher performance segment. Similar to the Carbonaut pads, they have an adaptable surface with very high thermal conductivity. Compared to Carbonaut pads, KryoSheet offers a significantly higher thermal conductivity as a high-end product.
