Installation
Neptwin mounting system uses universal backplate, which needs to be assembled before installation. Once the backplate is assembled using four standoffs and holders, it's positioned on the back of the motherboard. Four spacers are placed on the standoffs. On top of them two mounting brackets are placed and secured with nuts. Note that coolers using this mounting system can be installed both vertically and horizontally, depending on how holding brackets are installed.
With brackets installed, apply thermal compound, put the heatsink on the CPU and secure it with a holding bar. In Neptwin's case it's quite hard to do since heatsink is very wide and holding bar fits between the two towers. A long and thin screwdriver is required for installation. Fans are mounted using steel clips. Optionally, anti-vibrational pads can be installed on the fans to reduce possible vibrations. With fans installed, Neptwin covers all memory slots so there's absolutely no way to use DIMM memory modules with tall heatspreaders.
