Yup those deltas wont work on the controler, but you can connect them directly to the PSU and have them working 100% rpm which is what you want at the end. And that way if pool goes down or internet goes down your device wont be fried...
Sorry for my question, but how can I connect this fan directly to PSU ?
Shadow,
Sorry to hear the 3.9 amp fan you chose did not work. I bought all of my fans initially for my S4's. I assumed they would be fine as well for SP20's and S5's. It appears now I could be mistaken. I paid more attention to CFM and RPM rather than amps or watts.
I hope your rig is not ruined.
Does anyone here have specifications for the watts and/or amps for fans with the S5?I'm not sure about the fan someone else recommended that does not have quite the RPM's the BITMAIN fan installed in the S5. Bitmain's fan could easily go up to 4,000 RPM's. The one someone recommended was 3700 RPM's maximum.
The only fan I'm aware of at the moment to offer greater than 4000 RPM's with a lower amperage than the Delco 1212 series fans is the following:

CONNECTING STRAIGHT TO PSU:First, you may need to get a
4-Pin Molex Male to 6-Pin PCI-E Female Power Adapter Cable if your PSU did not come with this cable included. Some people are using server grade PSU's with custom made breakout boards that more than likely did not include the cable I mentioned previously. Here is a link to several choices of that cable:

4 pin molex to 4 pin fan connector if your PSU did not come with this cable included. Here is a link to several choices of that cable:

If anything, it's the fan that could be harmed by not having enough amperage supplied from the rig instead of the reverse.
I honestly belive your S5 only needs to be shut off for a while [Maybe after doing evening a hard reset] then turn it back on to see if it begins to hash.
Let me know how it turns out.
PS - IF someone knows the specs on how much amperage is provided by the rig for the fan(s), please let us know?Sorry i don't know the actual stats some one told me once but now i can't recall then but i do remeber don't go over 2 amps if he didn't keep trying to make it work , turning it off, unplug etc then doing a hardware reset should fix it .
fans have to be below 2 amps for the S5 these work just fine on them i use them on my S5's
I have OC with two of these fans on one S5 with no temps over 60 c so i know they work well . Sense i don't like OC i usually dont much but i run two S5 once @ 400 for two days. HW error were low enough and no temps ever went over 60 C but most of the time or all of the time i keep my S5 at 350 unless something goes a mess then il OC them just to get back on track . that's if speeds drop for no reason etc and a reboot won't fix it. if this helps it doesn't have to be a PCEI cable most fan come with the right converter plug or molex and even G-blade does it just plug it in using one of the Sata plugs from the PSU that has the 4 pin molex on one end all ATX psu come with that unless you buy oem, the fan all most all ways comes with the right converter plug .
with the fans I use he needs two and do it push pull which make better sense then have one and stand them up it does lower temp 3 to 4 degree or more standing them up using a box fan didn't work for me it made the S5 temps go up and work harder .
Phillip made a post to some else about noise so i tried it and it work well for me on 4 S5 , i have 9 miner in my house atm I'm about to my limit i want ever .
but its little bit nosier. I have yet to try two
