This bundle includes the Eisbaer Pro Aurora CPU AIO and the Thermal Grizzly 1700 Contact Frame. The Alphacool Eisbaer Pro Aurora CPU AIO water cooler is a special development for processors with particularly large CPU cores. These include the AMD Threadripper and Epyc processors as well as the Intel CPUs for the LGA 3647 and LGA 4189 sockets. With the Alphacool LGA 4677 Mounting Bracket (item no.: 13764) this cooler is also compatible with the Intel socket LGA 4677. Compatibility: AMD: AM4 / AM5 / SP3 / SP6 / sTR5 / sWRX8 / TR4 Intel: LGA 1700 / LGA 2011 / LGA 2011-3 / LGA 2066 / LGA 3647 / LGA 4189 (optional) / LGA 4677 (optional) / LGA 1851 Technical data Radiator L x W x H: 390 x 120 x 30 mm Material cooling fins, pre-chambers & cooling channels: copper Material thread: Brass Material outer casing: Stainless steel Connections: 2x G1/4" The Thermal Grizzly CPU Contact Frame Intel 1700 LT is a mounting aid for Intel mainboards with the LGA1700 socket. The contact frame replaces the standard ILM of the mainboard and improves the cooling performance of the CPU cooler through optimized contact pressure. The "Lite" version of the frame is manufactured using injection molding. The standard Integrated Loading Mechanism (ILM) has contact points located in the centre of the elongated CPU. Due to the resulting uneven contact pressure of the processor into the socket, the surface of the Integrated Heat Spreader (IHS) curves concavely. As a result, the base plate of the CPU cooler rests primarily on the edges of the IHS, so that the thermal "hotspot" in the middle of the CPU is not optimally covered. Removing the mainboard's Integrated Loading Mechanism (ILM) may invalidate the mainboard manufacturer's warranty!
