Powering The Pump

[Bashful Husky]

I have an EK Pump/Res combo and from what I can tell If I plug it into a pump header it will be running at 100% all the time. However, I don't want that much noise or to put the unneeded strain on the pump. Can I plug the pump into the CPU fan or case fan header to have RPM control?

Ek has 3 different pump-res combos!!!

d5 abd ddc use molex for power and fan header for pwm control/tacho reading, there is a small one as well, looks like a ddc, it was rated for around 12 watts/1amp and it can be connected to most of fan headers on your motherboard, as long as they are capable of providing enough current. I have a simmilar pump but a chinese bykski, it is running from the cpu header, however you must set it up in such a way that the upper temp of the cpu has to be below actual cpu temp under very heavy load

for example your cpu runs 78c under stress test with 70%  thus the pwm signal must go to 100% at around 85c 

And keep the fan curve as flat as possible

I have a dual XTOP D5 from EKWB.  I run it at 100% all the time.  It's silent.  You won't introduce any more stress on the pump as it's designed for a lifetime of 100% usage.  That is unless you have air running through it constantly which would also explain lots of noise.
