Recently completed a SG-05 build, specification as follows:
DFI P55-T36
i5 750
4Gb Corsair XMS3 DDR3 1600
Scythe Big Shuriken
Silverstone Sugo SG-05
Sapphire 5770 Vapour-X
500Gb WD Caviar Blue
Originally I'd assembled it with the stock Intel cooler to establish a baseline for noise and temperature while I waited on my Scythe cooler.
As you can see from the last picture the Scythe is a tight fit, I would have liked to have orientate it so the case fan would blow down between the fins but turning it 90 degrees wasn't possible as the heatpipes would extend out past the edge of the case. It became readily apparent that leaving the power supply in it's original orientation wasn't advisable as the heat from the Scythe and the GFX card was cooking it, flipped the power supply over so it was drawing cool air in from top of the case, much better. The next thing I noted was that the Scythe was blowing very hot air down and although keeping the CPU nice and cool, it was overheating the VRM's which have no heatsinks on this board. Reversed the fan on the Scythe and shimmed it up as reversed the blades would sometimes contact the heatsink itself.
With these few changes, temperatures are nice and cool, spent considerable time running IBT, Prime, Furmark etc with everything at stock speeds for now to establish a cool baseline temperature.
A couple of notes regarding noise, the Vapour-X card is as silent as can be, with Furmark running for hours most I could get the temperature up to was about 69C and never even noticed if fan speed changed it was that quiet.
The Scythe has a low bass like hum to it, only really noticeable when you have your ear up to it, psu fan has a higher pitched sound to it but again you need to be very close to hear this. Overall it is not 'silent', at least not to the standard I normally aim for with regular builds but it was not unpleasant to have the thing sitting very close to me.
Hope this information is useful.
Please forgive the pictures as I'm hopeless at photography.
