Thermalright today rolled out the Silver Arrow IB-E Extreme Rev. B CPU cooler. Thermalright has made changes to the design to make sure the fin-stack is slightly offset from the base in directions that free up headroom near the memory area and topmost expansion slot of a typical mainstream-desktop motherboard, giving you easy access to the memory and M.2 slots closest to the CPU socket.

Heat drawn from a heavier mirror-finished nickel-plated copper base is conveyed to the fin-stacks by eight 6 mm-thick heat pipes. The lavish use of heavy copper used in this heatsink make it tip the scales at 850 g, without fans. With both its fans installed, the Silver Arrow IB-E Extreme Rev. B can handle thermal loads of up to 320W. Each of the two included TY-143 140 mm fans spin between 600 to 2,500 RPM, pushing 31.4 to 130 CFM of air, with a noise output ranging between 21 to 45 dBA. Thermalright has updated the CPU socket support to include AM4 and LGA2066, besides LGA115x and LGA2011(v3). The heatsink measures 155 mm x 130 mm x 163 mm (LxWxH). The company didn't reveal pricing.
