## Description

Review: Effective and very low profile for rack builds - Perfect for 1RU Rack PC Build with Core-i7 7700K and Supermicro X11SSV-Q motherboard. Definitely a bit louder on boot but once the CPU temperature has stableized it's quiet and quiet enough even for my home music studio use. I haven't really pushed it to large multitrack recordings yet where CPU sits at 100% but I'm assuming I won't have to push the system that hard for the recording work I do which is limited.
Review: Perfect replacement - A good low profile cpu side exhaust cooler. Great for a 1U rack mount. Well built
