@RchGrav that fan is one step below this fan a little less air a little quieter

http://www.ebay.com/itm/191443200211

which sold out in under 6 hours since I posted about it in this thread.

you pick or the one above should work. the one above is gone. hell maybe mix one of each.

I had the 3 pin version of yours it ran at 2800 or 3000 it was okay I did some testing early but it was not a pwm.

It cooled better then the noctua cools. it was noiser then the noctua

it cooled worse then the stock fan. it was quieter then the stock fan.

So if you get the pwm version cheap why not? the worse case is you will need to run the s-5 at 331 or 325 not 350.

Can you get the numbers on the existing fan by any chance?

Or .. what CFM do you think is actually required by the miner to run at stock frequency under normal environmental conditions?

I had a 3000 rpm fixed speed 3 pin delta delta it was between 2800 and 3000 rpm . quieter then the stock and kept the gear cool enough to go to freq 350. I think it is 148 cfm at 3000 rpm
