PWM Pump help

[Malek988]

Hi guys tomorrow the loops is complete... would have been today but when connecting all the tubing i realised i needed more 90 or 45 degree fittings

Anyhoo My pump has a molex for power which ive gathered but there is also a fan connection.... silly question but does need plugged into a fan header on the board?? All my fans are controlled by grid v2 and cam so i have nothing plugged in to the fan headers currently.... and when I'm filling the loop nothing will be plugged to the motherboard so what speed is pump going to run at??

Thanks in advance.

You can control it in the grid also mate, with the pump speed my advice would be tied to CPU but with large flat ranges not curved.

If you had say a curve up with temp targets you’ll find it a bit annoying as it revs up when say you open an app and the CPU spikes in temperature momentarily. Flat ranges mean that won’t happen, you will probably find the flow is adequate with about 35-40% power, keep that flat and stick an increase in at about 60c if required which will stop the jump on and off.

When filling it will run annoyingly slow if it’s older generation, get one of the 24pin jumper blocks here and that should solve the issue and allow full speed while filling - that or use a paper clip to jumper the fan also works but less clean/safe of course.

Good luck...

Thanks for the advice, used that very jumper! filled no problem... Grid however the software cam is terrible so many problems, i will be looking for something else to control my fans, but ill keep it in mind for connecting the pump to.
