Looking at geting ths Antminer S3 or S5.

Sure S5 is your choice.

To reduce the noise you can buy 2 less noisy fans. Many of people here prefer Delta fans, but you are not limited here with this vendor; you can compare a characteristics of Delta fans here to start - look for fans like AFB1212HHE-TP02, AFB1212VHEX01 (a little more noisy).

Also do not forget that S5 cooling probably need to be modified. New S5s sometimes content little radiators from "external" side of PCB, where the little copper plates are placed. These are the right place for BM1384 chips to dissipate heat from.

The plates marked with little red circles (the picture is not mine) are without radiators.

With such little radiators the hashing blade became cooler, so the controller reduces fan's speed, which lead to noise reduction. You are free choosing the radiators, but their base dimension should no exceed the dimension of that copper plate. For the safety reason.

Do you have an ebay link for these heatsinks / radiators? I would be interested in these. My S5s fans have their ar$es on fire since summer started.
