Also what could be the impact putting tree videocards in parallel before CPU and visa versa.

 

You would lose pretty much nothing. The coolant is circulating too fast inside your loop.

Damn that is clean... Great work.

Testing has shown that loop order really doesn't matter, at least from a cooling performance standpoint.

Like Kinaesthetic has mentioned, due to the power / flow rate of modern pumps, gravity has little effect on performance.

Just follow the golden rule of having a reservoir before your pump so your loop never runs dry.

That being said, how you set up your loop will have an effect on how easy it is to drain and bleed air out of your loop--but you'll have to ask one of these experienced fellows for more info on that. thumb.gif

Gravity has no affect at all on a closer loop.

I hear people mention-Keep the res in front of the pump!

Its a loop, so isn't the res always in front of the pump-OR always behind it?
I am just JKing-I know what people mean.
It still really doesn't make sense?!?!?!
It wouldn't matter in a closed loop, unless you have air in the line, which isn't a good thing.
...or a leak, which is worse.
I say, just keep it topped off and you wont have a problem.
What about an AIO, or the people that are running a custom closed loop without a res?

Just my cent and a half...

The only reason a reservoir is mounted before and above the pump is to make bleeding easier. It doesn't matter if you put the reservoir somewhere else if you don't care if it is a nightmare to bleed.

I do things differently-I also pump out the water-Yes, I have run my pumps dry before.
I also pump in the water.
I have done this for all my WC builds.
I put in as much water as I can and blow in it, to push the water as far into the loop as I can.
When I cant blow it any more, I turn on my system-Yup, turn on the whole system-no leak testing, I am confident in my work. (this will come back and haunt me-lol)
...and when the water starts flowing to the point I can add more-I just shut off the PSU-this usually takes 3-4 times.
YEA BABY!!!-shock the system

Differently indeed!!!

If the loop already up & running, then of course it wouldn't matter whether the res is behind or in front of the pump. But how about new loop & you're about to fill the coolant in the loop? If the res is in front of the pump, the pump will run dry before the coolant circulated through the loop & this is bad for the pump. The idea is to make sure the pump already filled with coolant before you power it up. This is why the rule of thumb is to have res before pump.

How long you have use your pump? I asked because AFAIK a pump that have run dry even for a moment, sooner or later die.

No issues with my active plate. Where is it even leaking? At the actual connections?
