Got myself AntMiner S5 a month ago. I was surprised how bad cooling solution it has. Loud fan, bad heatsink design and a lot of air not even going through the heatsinks. After a month of playing with it and some 3D printing this is what my small rig currently looks like (just ordered the second S5):

It's hashing 1.35-1.4Th/s (clocked at 425MHz), temps of the miner are about 42°C higher than ambient while hashing at that rate. 34°C higher than ambient at default clock. Which means I don't need to fear of hot summer anymore.
