Filling loop, help with reservoir install

post #1 of 8
Thread Starter 
Is it okay to install bitspower reservoir this direction? Basically the liquid comes in from the bottom through a 90, up through the silver tube, then sucked out of the bottom to the mpc35x pump.

I installed the tube thinking I don't want the in and out so close together. I did not use the bitspower vortex breaker. I am filling the loop now, but have a lot of foam (could also be the swiftech hydrx additive foaming).

I drained the loop some and added more distilled water to reduce the hydrx, and also only filled reservoir 3/4. This has helped and been running a couple hours, but still seeing a bit of foam/bubbles.

Most people I see install the IN going through the top downward though the tube and then out the single (opposite) side. Is the way I've installed going to cause problems with air bubbles? I do like the top of the res sticking out as the case is not so roomy, and for easy fill and drain.

If the bubbles don't appear to be going down into the pump should I care about the foam layer?

It looks plumbed correctly,fill the res to the very top and keep it topped off thru the whole filling process.

If I fill it more the foam will overflow.

It looks like I my water in my res moves much more than I see in YouTube vids. The downtube (well uptube in my case) could be causing it, or simply be cause the pump is running at max off jumped power supply. The waterline is very wavy, much higher on the side with the tube. think I should remove it?

Fill it and put the fill port stopper in. The foam cannot get thru it and it will settle the fluid down.

Seems it was the pump running at full speed off of the power supply makes foam.

Once I got it running on the aquaero at 50% speed, everything seems normal.

the foam will dissapear in time. like what B negative said fill it up and put the port lid in

The foam is caused by the surfactants in the coolant. Think dish soap, dish soap is a really thick surfactant, pouring water into it causes bubbles. Same basic principle with surfactants in your coolant, just in a much less intense manor. More turbulence causes more bubbles, and the MCP35x is a hell of a pump. Like you saw, turn it down and wait for them to disappear. Surfactants are good for your loop, it will help prevent scaling which is particles settling on the walls of your loop and will break surface tension so if you're thinking "Why is this in the coolant?" that's why. How you're using your reservoir is completely fine, people usually wire it into the top for two reasons. One, it generally allows for an easier/shorter coolant path making less tubing and a cleaner build. Two, it mixes up the coolant in the res, so if you're using a nanofluid or like to add dyes directly to the loop it makes it easier. The way yours is wired in is actually the exact same format my reservoir SHOULD be wired in, it's perfectly safe. Sometimes plumbing it like you are can cause a "Vortex effect" but I think the design of your reservoir in of itself prevents that. Should be perfectly fine, tune the MCP35x down to 20% or lower and the RPMs will drop to 1200rpm which is the lowest the MCP35x can achieve. I'm not sure how the aquaero interacts with the MCP35x in comparison to a PWM header from a motherboard but with normal motherboard ports you only get between 20% -60% control. Anything above 60% will give you 4500RPM which is the pumps max speed, anything below 20% will give you 1200RPM. You DO NOT get a full range of control, anything between 0-20% and 60-100% will not change anything, that is assuming your aquaereo interacts in the same way the motherboard PWM port does, IDK maybe they tuned it to work well for the MCP35x.

Anyways, hope that helps.

Thanks for the help.

I have the pump connected to the aquaero 4th spot (PWM), and it does have the range you mentioned.

The issue I have is power vs. RPM is reversed, as I raise power in aquasuite, RPM's go down and vice versa. Will look for an answer, maybe I need to switch the signal wires.

Since I been messing with this watercooling build a few days straight, think I'll just play some games for a bit. smile.gif
