You can control fan speed via FSD in the settings, at 70% the fans aren't too loud and provide decent cooling, I also taped up the fan shroud and placed some card over the majority of the GPU heat sink and taped that up too to provide a better vacuum. Switching the CPU heatsink for the copper pipe one allowed me to install a 60mm Fan on top of the extended portion of the GPU heatsink, once the case is back together I'll punch some holes in the top of the case so it pulls cool air in at the front of the heatsinks. At the moment with the console idling it runs at about 38-40oC overall, I think this will improve when the case is back together. Will check temps when playing too, just sorting out installing a 3.5" hdd in place of the dvd drive at the moment and getting all my ISO2GOD sorted. Thinking of superglueing a dvd bezel to the front and drilling some holes in it to allow a little more air in through the front and make it look less ugly.
