Question 1

can each fan be controlled individually with this?

Accepted Answer

No, there is only one connection to the control pin on the motherboard. All fans connected to this have the same control input settings.

Question 2

Would it be OK to plug different size fans all together? Mainly 120mm and 140mm fans.

Accepted Answer

Yeah that should be fine , this hub has all 4 pin headers and it’s powered by 24 pin sata, fan size shouldn’t affect power draw

Question 3

Nothing seems to list the exact type of SATA power connector and it doesn't indicate it comes with one so I was wondering if anyone could point me in the right direction?
It took me awhile to find anything even remorely close to it but there are a few options and I'd like some clarification if possible.
Would a 'SATA 15pin to 6pin PCI Express Card Power Cable' work or should I be looking at something with a different pin count?

Accepted Answer

The EnLabs PWMHUB10S 10 Ports 4-Pin PWM Fan Hub uses a SATA 15-pin power connector. You should be looking for a SATA 15-pin power cable, not a 6-pin PCI Express Card Power Cable.

Question 4

I understand only the "CPU" port has feedback to the motherboard regarding fan speed over PWM. I thought fans 1-9 would run at the speed set from the motherboard too though, is that not the case?

I am seeing fans 1-9 run at 100% speed, while the "CPU" output appears properly regulated via PWM.
I am using all PWM (4-pin) fans.

Accepted Answer

Weird... I have 2 of these in 2 systems, and fan speed off the fan hub (all 4-pin PWM fans) controlled as expected. I do plug the fan hub into just a chassis fan header, not a CPU fan header, and I have the fan curve set for that chassis fan header for both systems. Not looking at HWinfo or anything, my fans connected to the fan hub definitely are not running full 100%. I'm sure you have, but may I suggest just making sure if you have this plugged into the CPU fan header, the fan curve you're setting in the bios or wherever is actually for the CPU fan header?
