Default Fan Controller for 5 fans

Looking for a fan controller for five of these fans https://www.newegg.ca/Product/Produc...218.1522961548


I have a NZXT Sentry 3 and it does not work, it works with every other 120mm fan I have, but not these, it just ramps them up to full and there is zero control, so, as stated above, I am looking for a controller that can work with these Deltas.
Thanks.

Do you have the PWM version of the deltas or the 3 pin? The sentry's specs say that it's supposed to work with both 3 and 4 pin fans but what you're describing (pegging fans to 100%) sounds like what my silverstone controller does to 3 pin fans.

Forgive me, not very computer savvy, but the Deltas are definitely 4 pins. The S3 works fine with the Corsair Mag Lev. fans which are also 4 pin, just not with the Deltas and I wasn't sure if it's a power issue or voltage????? I also have the S2 and they do the same thing, ramp right up, which is okay but with five of those at full I am afraid my tower might turn into a drone :)

That's weird. Do the fans have 4 wires or did somebody just slap 4 pin connectors onto 3 pin fans?

How about individual control? Can you control the fans individually off of a motherboard header?

When you say it ramps them up to 100%, is that when mixed in with other fans, or when running nothing but the deltas?

They are definitely 4 wires coming directly from the units themselves. I was warned not to attach even one directly to the motherboard, apparently these things are a bit of a beast :) I tried mixing with the Corsairs but the Deltas again went right up to 100% the corsair's were controllable.

Not sure what to say then... the specs on your current controller claim that each channel is rated up to 15A, and the deltas are supposed to max out @ 1.74A. In theory there should be no problem at all.

You can try contacting NZXT, but the real culprit would appear to be the deltas, and I'm not sure you'd get much response back from them.

Ya, I sent them an email, not expecting any results from that.
I will wait until the other 3 Deltas arrive, plug them all in, and see if that does anything different, if not I'll be rocked like a hurricane :)

The only other suggestion I can think of would be to try them on a dial type controller. It really sounds to me like the PWM isn't working on those Deltas.

That's the controller I'm using, and the symptoms you're describing are what happens with it when you plug a 3 pin non-PWM fan into it. (BTW... shoutout to this particular product... inexpensive and allows every fan my case to be controlled by a single motherboard header).

Wow too funny, I have that one, I like that I could plug in all my 120mm fans and have then run at full speed, but those were the Corsairs that ran at max 2400rpm.
when I plug in these Deltas, in most slots they don't work at all, there is one plug on that eight plug adapter that they do work, but again it maxes it out and I know that is what that adapter does, but at 4000rpm it's a bit much, hence the controller idea :)

I am super stumped on this one, can't get any replies from the guys at Toms Hardware and usually they are all over most topics.
