Two Antminer S3+ or one Antminer S2?

Hi!

Which would you recommend? Two Antminer s3+ or one antminer s2?

Two antminer s3+ w/power supply will cost me $600 (canada)

One antminer s2 will cost me $550. the S2 has built in PSU.

The thing is I have free electricity for the next 4 years. So the S2 is a little bit more cost efficient.

But I live in a small college dorm. I want to minimize sound as much as possible.

I will be about 4m away from them.

So it comes down to which set up will produce the least sound? Two antminer s3+ w/ 800 watt PSU? or one antminer s2??

Thanks
