Hi all,

360 XPSC RX Rad in the roof, EK 250 Basic Res in the middle Swiftech MCP355 Pump..? ... getting there but..

While i'm still waiting on Swiftech for an LGA 775 bracket to be delivered for my Apogee XT i have a few issues concerning the location of my pump.

I've been told that it needs to be at the bottom of the loop however I've seen a few in the 5.25 drive bays, in a similar configuration to mine as it is now (res / rad etc) my question is how can i avoid fluid starvation on startup and how much of a pain will draining be if the pump is in the 5.25 bays?

It will be easier mounting it in the 5.25 however i can mount it at the bottom below the Hardrive caddy's.

Any help will be greatly appreciated (i will get some better pictures when this is all completed, there is a lot more to come.)

Do you have a top for your pump like the ones xspc and ek make? With them you could mount it easily under your res instead of your fan. Screwing it in the mesh holes. Otherwise I guess having the pump above the res would make it difficult to fill as you would have to lift the res to prime it, run it for a few secs and then do it over and over until its full. Also bleed it would be difficult.

Anyway hope it helps, if not someone else might know more about pumps in higher positions.

Pump location doesnt really matter once the system is filled and bled. Put the pump wherever you want and then just take the res off its clip and hold higher than the pump. Bleeding usually only takes minutes for me. Once the system is bled put the res back in the clips and you're done.

Or just bleed everything 1st and then mount everything.

Is the tube in the top of the res going to the rad or to a fill port?

^ Judging from the text I would guess that the tube into the top of the res it the one from the rad in the top.

Could you not move the res up a bit or does the cable foul the res? Ask because people say about the res being higher but surely as long as the water level in the res is higher than the pump then mavity will still do its job of making sure water is in the pump.

Thanks for the responses guys, the pump does not have a top i think i'll take the advice and put the pump where ever the tubes look best.

The res goes directly into the rad at the top, i can't move it any higher or it will kink the tubing but i think this is changing anyway as i was going to have it res > pump > cpu block > rad > res but it looks like i will get better temps going rad > cpu block.

Ideas?

If the tube goes from the res to the rad direct, how are you going to fill your loop? If that is the basic version of the EK res as you say it will only have one port at the top. Are you planning on filling via the bottom spare port or is there a T line hidden somewhere? You possibly could turn the res upside down so you'd have an extra port where it needs one, i.e. the top, but I'm not sure you'd be able to use that inner tube mounted at that end, which means that air will always go back into the rad whenever the pump is off. If that is an inner tube that is, hard to tell.
