Res and Pump order confusion

post #1 of 7
Thread Starter 
It's my understanding that the res should be above the pump's inlet.

I am thinking of feeding my pump from an ek res x2 using the top outlet of the res. The pump would be placed to the side of the res. Technically speaking the res is still above the pump but the water is not being fed into the pump by gravity. Would this create issue with the pump when I first turn it on? I was sort of told that I should tilt the casing so that the water is flowing into the pump when I first turn it on and once the loop is running, I can put the casing back to normal position.

You don't want to run pumps dry, so it will need some water when you go to start. If you want to tilt your case and what not, it can work. However, to save yourself a headache or two; I'd suggest putting the pump below the res, so gravity does it's job.

Unfortunately if I put the pump below the res the whole loop would be reversed. Also I have a rad at the bottom of my case (800d) and I'm using an ek 250 res. The only place I can put the pump is at the bottom hdd bay or the odd bay. I'm thinking of putting it in the odd bay but I'd have to feed the pump from the top of the res would and the pump would be below water line

Pics or diagrams? The problem might not be that bad... I was considering doing a similar thing, but I decided to just use an unused HDD cage to house the pump... Just need the rest of my parts

Water would still be carried to the pump by gravity just like it is in a siphon. Priming a pump in this orientation will be more complicated.

I'll draw out a diagram shortly. Yes, the water would be "sucked" into the pump but when turning it on for the first time, the water wont be right at the top of the pump's inlet so it'd be sucking in some air if that matters.

PC water cooling pumps don't suck, they push. Hence why you need to have a reservoir above the pump. Without gravity feeding water to your pump it will burn out very quickly.
