I had posted this on Toms Hardware without any results so I'm hoping somebody here can help me again:
Okay so I bought this fan hub controller:
http://www.phanteks.com/PH-PWHUB_02.html
And my motherboard is this:
https://www.gigabyte.com/us/Motherboard/GA-Z270P-D3-rev-10#kf
MB has all four pin connectors.
I have the white fan plug from the hub going to SYS Case Fan 1. The case is a Phanteks P400a with 3 fans at the front that are only 3 pin connectors.
Using Hardware Monitor the fans are always at 1400rpm, no matter how freezing or boiling things get. This is causing my evga RTX 2080 to start sounding like a jet engine again before I got the new case. I feel like I'm back to step one ~rips out hair~
Anybody know why it isn't changing the fans based on the temp curves I've set in the BIOS?
Thanks
Edit: Maybe replace the front three fans with high quality 4 pin noctua ones? Which I was planning to do anyway... but one step at a time I just wanted to get the hub working first so I can have six fans total
Well ok. You probably shouldn't buy anything until you figure out how to run what you have.
Did you read the fan controller manual, read it again, read it a third time, and feel that you fully understand it?
http://www.phanteks.com/assets/manuals/PH-PWHUB_02.pdf Did you read the motherboard manual, section 1-7 regarding header pins and section 2-2 Smart Fan 5 Settings?
https://www.gigabyte.com/...support#support-manual I'm going to guess that this is your case fans:
http://www.phanteks.com/PH-F120SP-LED.html It is a THREE PIN fan, it has GROUND, TACH and VOLTAGE. Speed control is done by CHANGING THE VOLTAGE. If they are running at a straight 1400rpm, it is because they are are getting a fixed 12V and running at their max speed.
When that fan is connected to the motherboard header directly, the bios fan control needs to be in VOLTAGE MODE for that header. It will then follow whatever control scheme you select, controlling speed by reducing voltage.
According to the fan controller manual, it can take either PWM or variable voltage control signals into the INPUT port. It translates the signal for both types of fans, which are plugged into FAN 1 plus the correct headers on the controller. It requires separate 12V power from a SATA cable.
If your controller is hooked up correctly per the manual and you are getting a fixed full speed from the fans, chances are that is what it is set to do in the MB bios and you need to tweak those settings.
