Silverstone SG04 case is a superb, very compact but capable of hosting a micro ATX board and a good size SLI graphics cards. The trouble is that all this technology packed in a compact space it heats. It gets very hot, so that the case get very hot to the touch and the PC stops short, engaged in thermal protection. Not wanting to give up this case I replaced the two 120mm front by two Coolink SWiF2-120P. More crashes, air circulation is sufficient to cool the interior of the PC, and fans are currently less noise than 120 mm fitted as standard, even at full load. To see if the bearings held in the term but for now these fans are more and enchanting.
