Watercooling loop advice

[velis]

I want to build me a completely silent system. I figured since my main rig is right next to the wall leading to utility room that I'd best drill a hole into this wall and move the bulky / noisy stuff to the other side. The UPS is already "on the other side", now I'm aiming for WC components.

So far my WC setups have been a Zalman's Reserator and a custom EKWB loop stuffed completely into a Silverstone GD05 --> This one was really nice since the case is extremely small yet I cooled both the CPU & a Radeon 5870 with the loop.

Here's the pic of proposed setup. Stationary, I'm not planning on ever moving main rig.

The complete height difference is 1.5m (5 feet). It's quite different from my previous setups so I'm not sure what components fit where in order for me to be able to fill, drain & operate the loop with least issues.

I worry that pump / res combos such as this one are able to push water only: do I need the pump running when I start the draining procedure so that it pushes the water far enough that gravity can then do the rest of the job?
Or is it enough to just open the valve at lowest point in the loop and water will just drain by itself?

Also, the height difference might be an issue as well: so far max height I experienced was some 20 cm. Now I'm moving to 150! Will the pressure difference cause any leaking issues if I don't use extra caution with fittings?

Are there any problems that I have not detected with this setup?

just some points
all my pumps and rads and 2nd power supply [turned on with a 12v relay powered by the system psu] are under the floor
but my bay res is in the system , hightest point of the loop for filling and air bleeding

I like D5 pumps
not seeing the res not sure if it runs dry that you will catch it in time , maybe a flow meter that has a auto shut down

or my choice would be to mount the res on the cpu/system side higher than pump [12-16" ??] up on the wall or custom stand [use stand alone pump on rad side]
not sure if pump will have enough water but use 1/2" tube for res to pump feed

also I use quick disconnects so the cpu/system can be taken out of the loop without draining all of it.
and I have spare QD to open the fixed ones to drain/fill which ever part of my loop I need to.
btw I use a wet shop vac to drain the loop takes 10 seconds [held by hand close to a open quick disconnect and open res fill port

also any remote power connections eg power to the pump I use a rad fan with it , with its rpm output to a fan controller with a alarm
feature if there is a dis connection the alarm go's off, some pumps have rpm monitoring but I'm not sure it it sets off an alarm at 0 rpm


also a rad with a air bleed might help as air does not like going down in a loop.

it pushes the water far enough that gravity can then do the rest of the job?
closed loop so height is not a problem in your case , push up = pull down
good luck
