Question Sanity check... I can power D5 water pumps with SATA power, right?

[fcar1999ta]

Pretty simple... I am pretty sure I can, but I figured I would come on here to confirm. I am building an external radiator cooling loop, which will require multiple water pumps. My mobo has one pump header, which does not have enough power for more than one pump. So, I am planning to use a PWM splitter to control the pumps, and SATA power to power them. This will work, right?

Well, you have no option other than to use SATA for power and PWM for speed control, since EK-Loop D5 motor only has SATA and fan PWM header cables.

Lol. I assumed that they ran off of the header since the header can support 36W. Can you tell I haven't opened any of the boxes yet?

I assumed that they ran off of the header since the header can support 36W.

While the 4-pin PWM pump header can support 36W, the product image shows the fan header having only 2 wires: RPM feedback and PWM signal. No wires for +12V and ground for powering it.

So, you jumped the gun? 🤔
