Something wrong with water loop layout?

post #1 of 9
Thread Starter 
Hey guys, I just moved my water cooling from a smaller case to my new 650D. My old setup was:

Raystorm
Swiftech Extreme 240mm rad
D5 Pump
XSPC D5 Tank res top

In the new case I added an XSPC EX120mm and also changed the res into this bay res: http://www.pccasegear.com/index.php?main_page=product_info&cPath=207_160_299&products_id=20409

I have the loop setup like this: Pump/res > 240mm rad > CPU block > 120mm rad
But with this new loop it seems like the pump isnt working properly, or there might be a lot of air trapped somewhere, because it idles at 50-60 and can't handle the CPU while its loading.

I have tried turning the computer around etc to try and get some of the air out but that hasnt helped

Can you guys see anything wrong with the way my loop is setup or any ideas I could try?







Thanks for any help smile.gif

First thing I'd try is remounting the block.
What thermal paste did you use and how dig you
Apply it?

Thanks a lot for the reply smile.gif

I used Arctic Mx4 and I just put a small pea grain in the middle of the CPU

I just tried remounting it but still no change unfortunately frown.gif


Also something else Ive noticed, after leaving the pump running for a while, only a small stream of water is going from the res into the CPU block, but the bay res is completely full. Though when the pump is off, that tube becomes filled up

Would that mean air is trapped in the rad?

Heres a bad pic of what Im talking about:

how much coolant have you used?

youve got a big a$$ air bubble.. one is in the 120 (hose bottom fed)
and prolly one in the CPU block. because the water is down-feeding and the air
cannot go down, it wants to go up... your gunna have to burp the pump in
lil bursts while tilting the case to chase the air out.

Is the inlet and outlet of the pump/res the right way?

Yeh the top is the outlet and bottom is inlet

I have switched them around and that made it work, and temps are decent now

But there seems to be another huge air buble thats developed in the tubing

I have tried running it without the inlet cover to try and get some of the air out, but the pump is spitting too much water so the bubble isnt leaving

I've heard a single drop of dish soap will help break up bubbles in your loop.

honestly, id drop the 120 out, revamp your hose routing and this will verify
the system for now (since you are having issues) less is more.
if you can raise your bayres to highest in drive bays.
RES/PUMP>CPU>RAD>RES/PUMP
thiswill fill the CPU block and push air into the rad. the rad can then push it
into the res. simple case tipping to burp the big air into res.

in your install RES/PUMP>RAD>CPU>RES/PUMP the air cannot escape
without laying the case on the side (res removed to keep pump submerged)
and veryting agle to chase the pockets out..

Ok so Ive switched the inlets and outlets on the pump and that seemed to make it work and the computer and run fine

But there is still a huge air bubble in the loop which I cant get out, so I probably will take out the 120mm today and see how that goes
