Can anyone tell me HOW I would connect this 280mm x 280mm x 80mm fan to 230 Volts?

a bit off topic:
had crackling/cracking(eng is my 2rd language, sorry) noise somewhere between 750watt and 1100watt, all inside the dps-2000bb....
will check again asap

Good tip. Just playing with the different setting to see the potential, I will reduce the voltage for the S7. Only getting this more for the Avalon.
Just curious - What ambient temperature were those guys running that they burn their boards? My garage is currently 65 degrees right now so I'm not as concern for a short test. What hash rate would I get at the lower voltage and that freq you mention?

some were under 50f
maybe 4600 vs 4730
I sent a PM to Finsky and waiting on a response but figured I would ask here.
I was sent the 4k set-up, purchased my own fans and set it up and the PSUs made crackling sounds. I assumed with the c19-c20 power plug from PSU that it would work with my 240v PDU (just like the 2880 set-up I currently have from finsky). I looked at the power cord and saw a small sticker that says 120v 15 amp, so I am thinking I have to buy a separate power cord c19-c20 rated for 240v 30 amps for both PSUs to work with the PDU but I am afraid that the crackling might have fried the PSUs utilizing the 120v plugs.
Please let me know your thoughts. thanks!
You have a different issue. The power cords are good.
The wires can handle 240 volts.
Need photos of the setup.
Need to know if you crossed the pcie cables as you can put them in backwards.
Do you power on with no pcie cables . Just the fans and no miners?
Just the fans, no miners. Is that the issue? I had to buy the fans separate and was going to try a few ways to set it up before attaching the miners.
I have some Sunon fans that made some crackling noise too, when I overvolted too much, like 12.9v.
But apart from the noise, they have been working fine for a few hours until I reduced the voltage for other tests.
Then, I swapped them for other fans.
My Ultrakaze fans were working fine on the same pack of PSUs.

@ nhando. You should save 3-5 percent per gh so 26/27 is how much it will reduce watts per gh on my model
On your model it should be 30/31 or so per gh of hash
Wow, so for the 130 GH dropped, I save 30*130 or 390Watts? That sounds too good to be true? My math might be wrong but if I do 5% off of 1500Watts at the wall is only 75 watts. so it's more like almost 2 watts per GH saved?
Sorry tiny iPad sucks.
30/31 is 95 or 96 percent so if you run at 4730 and you use .31 watts a gh
You should run at 4600 .30 watts a gh
So .31 x 4730 =
Vs .30 x 4600 =

I do not know what is wrong.

Do you have the Wattaged used with this underclocking and lower freq? Sounds like a good trade off for longer longevity with not much lower hash. Probably a reasonable amount of electricity saved via lower wattage too.

You are the MAN Phillip. Pictures are worth a thousand words as they say. I thought that was just a screw, didn't even know it's a Trimming / adjustable thing. WOOHOO. 12.55V now. Will connect the Avalon to this Board later this week. Right now it's busy warming up the house. Yes, I just starting doing the NiceHash casino on Kano pool. It's paying off for me with the current luck while I work on finishing up the 400AMP upgrade.
Update - Now that I'm over volting it to give it more juice, they seem to react much better to the 731M frequency then when at just 12-12.2V. Testing this for a few hours and see how stable this is as I'm surely over stressing my 2x2KW PSU at this load.

The batch eight should be under clocked based on the burn up complaints
If I kept the batch eight I would run at freq 687 and 11.85 volts

What do you mean trim it? Remove the switch and cut something? or remove the switch adjust it like Kilo's example?
trim pot is a little screw turning it is trimming it.
the board has a trim pot
Power on off> S_________M < volts meter
l l
l l
l l
Trim- pot > > T_________S < volts up or down
on trim pot think of it like a clock face :
turn clockwise for higher volts
counter clockwise for lower volts
turn it say l to - as mine is a flat blade
so the example I give is 90 degree turn clockwise from 12 noon to 3 o'clock
here i am maxed I set trim pot up and switch to high I am at 12.83 volts
I am running at nicehash and being paid .0051 a th

After seeing DMwardjr's Youtube video about respecting Electricity and that guy getting fried by high voltage, I have a fear of even touching power cords.... Haha. Only tried and true for me, especially after Phillip did another 1 saying, open the PSU at your own risk,,,,,,,,,,,,,,,.DEAD Meat. So I will only do what is considered tried, true, rinse, rather and repeat solution. No wild cowboy moves for me. Still have 2 kids to take care of. =)
P.S Thanks for the heads, up. Going to the Garage now to fiddle w the Voltage thing.
Update - The switch only have 2 position on my 4K board. Maybe I have a bad unit? Pulling it up shows 12.11V and pulling it down gets me 12.26-27. There is nothing in the middle or any other settings. I even tried taking out the nut / washer to make sure it was causing it to be stuck. Even tried pulling to the left and right. No dice =(

trim the potentiometer to the right to add some offset to voltage adjust.
switch in low position is overvolt, high position is undervolt.
middle position do nothing when you have it.
Finksy probably delivers the board with potentiometer set to a minimal offset to avoid trouble.
I'm delivering them set in medium position to get more offset (+/- 0.4V)

Does anyone see an issue with powering the radiator fans with an IBM 2000W BB PSU? I'm going to take the plunge to try it out. I need to know before I purchase 8 of them on Amazon to install in one door of my mining closet.
Any help would be appreciated. I personally don't see an issue powering them with the IBM 2000W BB PSU. I just want to make sure. One of you may know something I don't...
I would think the way to wire it up is similar to the way Kilo wired up his 180mm fan for the 3 x IBM 2880's.

It isn't an issue, I am running some fans from a 2000 the same way. Just splice the power and ground into a PCIe connector and BAM
