I read back a few pages looking for information about changing the fans on the S5's but was unable to find any information so I am starting the discussion over.

I received my 2 S5's yesterday and my parents promptly said "no" to the noise going on in the backroom from them.  So now I need to replace the fans and my thinking was just to put 2 of them on either end like the S3 and call it good.  I noticed on the controller for the S5, there are 2 4 pin slots so I figure this should be fine, but wanted to double check.  I am thinking of running out and getting these today...

and putting one on either end of each S5, but they are 3 pin connectors, should that be fine or should I find ones with 4 pin connectors (I thought 3 pin can plug into 4 pin slots?)  Also the airflow is 52.19 CFM, should that be sufficient to cool an S5?

Thanks in advance, I appreciate all feedback
They should run fine with two of those fans using the 3 pin connector, but you won't have speed control. Depending on your ambient you might have to throttle down the speed quite a bit to keep the miner cool.

Don't use the quiet editions, they really are rather week and I doubt they'll be sufficient at any sort of ambient. The AF120 performance editions are much better suited as they're moderately high pressure but still at an acceptable noise level. I use them all the time to 'silence' various miners without trashing their cooling [Without affiliate] [With affiliate]. There are also PWM versions if you think you'll need it in the future [Without affiliate] [With affiliate].
Yeah, that's why I added the caveat that speeds might have to be slowed down quite a bit. It would be interesting to see how much, but based on cooling S1s with similar specced fans I would guess you'd probably be ok running at 600-800GH/s in a 20-25C room.

Also, nice on providing links with and without the affiliate and making it apparent that the one is an affiliate link.
