They run with that open-built extremely loud full speed fan and still are over 50C.
Even the SP20's at Fan speed 50 are more quiet than these things.
I will use a new cheaper mod tonight-we'll see if it works. ~$20-24/miner.
Lowes in my area is completely out of pan M4-0.7 35-45mm screws. had to buy hex.
I surmise that S5 modders scooped them all up, LOL.
i think im going to probably pick a couple of these up.

they seem to flow alot of air and are a tad quieter..
probably not as quiet as the fans on the s3, but as long as they dont whine im ok.
It's my opinion that a fan with lower CFM than 4,000 RPM's should not be used on these rigs. They do run very warm with one fan. I presently have temperatures of 62 C on Chain #1 and 62 C on Chain #2 with the single fan at 3,840 RPM. The Ambient temperature is 74 F. The true purpose of getting a second fan should be for proper cooling of the unit. One should not be concerned as much about the noise as they should about proper cooling of the rig during the hotter months of the year.
Yes, a fan with 4,000+ RPM's will cost more but it's worth it in my opinion. Proper cooling and longevity of the rig is more important than the noise level to me. My opinion; that's all. Please don't take it personal.

The location matters too. I don't care how loud mine are because they are in my garage and can not be heard in the house. Now if it was in my house I would have to reconsider my options.
