Been a bit quiet on this for a while, a bit of progress has been made though, ive bought a Scythe Kaze Server fan controller,

This is an awesome controller and while the PC is not under any load the fans are off, when the temps rise (you can set these) the fans will spin quicker as the heat rises or spin at a speed you set, this means a quiet pc!
Ive also decided to watercool the CPU and possibly the GPU (not a full cover block) ive bought various bits of MM and ill re-use the pump from my last build, a couple more bits to get and ill be ready to carry on.
