https://www.anandtech.com/show/14120/thermalright-silver-arrow-ibe-extreme-rev-b-two-140mm-fans-8-heat-pipes-320-w hermalright 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. hermalright 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. I like the color of the fans but I feel they could have stepped up and added a little RGB.
