Reservoir Bleeding Question

Hey guys! I have been looking on the forums for quite a while and never registered to ask questions because it always seems like you guys always answer them :D I will be finishing up my water cooling setup this week, but i just got a question that i cant get off my mind. Exactly how does the bleeding work inside the reservoir? Does the water come in the reservoir and let the air bleed from the top of the reservoir? and if so, is there some tweaking i have to do in order to let the air out? I'm confused :confused:

First off, :welcome: to XS!!! :D

If you leave about an inch of air in the top of your reservoir the air will bleed it'self out.
What res do you have?

Hi V3lcro. Welcome to the forums. :welcome:

All I did to bleed the air out of the system is run the sys (leak test) and prob 30min into it, I turned my rad over, back and forth slowly and all the air will come out.

As far as I know, air is always going to be at the top. So If your rad is standing upright, and your in/output is at the top, you might have air near the input. By turning your rad upside down, the air is going to the "bottom" of the rad, then turning it back the other way, the air will move to the output.

If that makes sense?

A reservoir isn't really anything magical. Common sense says that if you mix air and water inside a container, they'll separate afterwards, with the air floating to the top.

All a reservoir does is accept the incoming water/air mixture a chance to separate. The air doesn't actually have to "escape" the reservoir, it just has to stay near the top, so the pump doesn't suck it back into the system again. Of course, if enough air stays in the reservoir, the outlet for the coolant might not be underwater anymore, the pump will start sucking air back into the system. At that point, stop the pump, and add some more coolant, then repeat. Continue until there's no more air moving through the system.

Depending on the layout of your system, it's possible that air will get stuck somewhere in the middle, which can lead to anything from extra noise to poor cooling, so you'll want to get rid of it. If the system can't push the air out itself, your best bet is to start tilting the case in all directions to make it easier for the air to escape.

for quick moves, you could topple ur casing slightly sideways to allow trapped air bubbles to go to reservior .. make sure u have the pump running at its peak speed so the loop water can push the air bubbles..

careful if ur setup is not fully secured on the casing ...

Thanks for the welcome guys, appreciate it! I have the EK-RES150 Rev.2 Multi-Option Reservoir. So basically in the initial leak testing i must make sure that there is no air at all mixing inside of the actual radiator or else it would of course not be good for the computer and the water cooling parts? Also just wanted to make sure at the top of the reservoir there is a little screw i could turn to let out certain amounts of air or is that for something else?

Here are some pictures of how everything looks so far

My computer:
Intel Core 2 Quad Q6600
Dfi Lanparty LT X48 Motherboard
Silverstone TJ07 with side window
Nvidia 9800GTX
PC power and cooling 750W silencer power supply
G Skill DDR2-1000 2X2 ram

Watercooling Parts:
Swiftech MCP-655-B Pump
Swiftech MCW30 chipset waterblock
D-Tek Fusion CPU Waterblock
Masterkleer 1/2" 13 feet of tubing
Swiftech MCR320 QB-K Radiator
EK-150 Reservoir

Easily said: air pockets decrease performance as they take space, which should be taken by water molecules that pick up heat and move it elsewhere.

I'm not aware of a little screw in EK's reservoirs, do you mean the top plug? You can use it for anything really, a different loop setup or to add fluid. It's not necessary to leave it open for letting out air: The air doesn't escape from your loop, it only moves to the reservoir, making the water level drop.

Thanks for the responses guys! I was just wondering also, would it be fine to tilt the case (with everything secured of course) every certain amount of time (say about every 30 minutes while the system is going for a leak test) to make sure that all the air is getting to the reservoir just to make sure most, if not all the air bubbles are out of the radiator?

That will be fine, as long as no air could possibly get into the pump.

Yeah, that's okay. Air tends to get stuck in rads so if your rad isn't mounted to your case, pick it up and give it a few shakes. You'll know it when bubbles come out; the pump will get louder and make a distinctive sound as the bubbles run through.

Thanks guys so much for the replies again! I will make sure to do that. I have one more question that actually crossed my mind as well today as i was on the topic of reservoirs, would i fill the distilled water into the reservoir which would then go into the pump and into the radiator, and so forth? Sorry if its a dumb question :confused:

that's what i did ... since i already fasten all the tubes ...
if u're unsure ... u could try checking this guide ... http://www.watercoolinguk.co.uk/catalog/dangerden.php
