Taming 120mm deltas.

[Scout]

Is there a externally powered PWM controller that can handle three 120mm deltas ? I have tried in the past with voltage control just too many amps.

this is the only kind of fan controller i know of that will handle high amps and wattage per channel. i ran a bunch of sunon high power 120mm and 80mm fans off of one like it (much older). check out alphacools gear. they have a big selection of quality fan gear.

The variable speed Deltas accept PWM just like any PWM fan, but beware that some on the market are designed to be used in mini split HVAC systems and will not work with the PWM used for computer fans.

If I split the 4pin connector and run the Power and Ground to molex and PWM/tach to the motherboard this would give me control without the amp draw on the Mobo?

That's pretty much the way to do it, but I would leave the ground connected to the motherboard as well.

This might also work and is powered directly from the PSU by a SATA cable:https://www.newegg.com/Product/Prod...pwm_fan_controller-_-9SIACJF6HF8769-_-Product

Only thing is there is no info about the amps it can handle and has the drawback of not being able to individually control the fans connected to it. All fans will get the same pwm signal but being that all three of the Deltas are the sam model that may not be an issue.

Alright so I had the same search way back when I was building my Ryzen system. Luckily the Crosshair VI provides two 3A fan ports to power these fans.

I used this NZXT Sentry Mesh Fan Controller and its great, it can be a bit touchy at the lower voltages, but it will give all 5 channels nearly 30W a piece.

I saw products like that and I have something similar coming I will report my success. I have always questioned the power delivery ablity of Sata connectors though. We will see.
