I built my system just last month in January. Its only been a month and the coolant in the reservoir keeps emptying up every week. I refill the reservoir but in just a week the coolant reaches 3/4 from the top and starts making this hisss sound and I have to refill it. The sound is like a turbo in a car engine when the turbo kicks in it makes this hisss noise. This has the same hiss noise maybe it could be just air since its empty.
I have the CPU overclocked to 4.7ghzs and running my graphics card in the same loop. I don't run the PC 24/7 I run it for 12 hours then turn it off at night. I usually just play FPS games and GTA plus some video editing. Though I don't see any visible leaks anywhere and I was wondering if it normal for the coolant to empty this fast every week. If there is a problem please let me know the steps I should take to fix this issue thanks.

CPU: Intel Core i7 3930K @ 4.7ghzs

RAD: XSPS RX360
Tube: XSPC Flextube 3/8 - 5/8
Fitt: Bitspower 3/8 - 5/8

That's what I am wondering where all the coolant is going. I tired my best to bleed all the air out of the system. Even though my tubing is black I am not able to see any bubbles but if you run the system long enough in the start it will eventually bleed all the air out.

it's either you got a slow leak somewhere or you did a very bad job at bleeding the loop, take the side of the case off and look for any liquid, and also put your ear close to the rad and tip the case about and listen for air moving

Well this is quite weird....
Are you sure there is no leak? There must be a leak, i haven't lost any water i believe for 4 months.
Have you bleed the system, so if you shake it there is no air rush?

I tired my best at bleeding the system. After that I let it run for almost 2 days so all the air was gone. But I will try your suggestion and see thanks.

I shook the system and there was some rush in the reservoir mind you the system was on. Should I try it with the system off?

Sounds to me like you had a giant mass of air still trapped in your loop after filling and closing it off. The "turbo" noise is the sound of little bits of that air mass going through the pump. Can you notice micro-bubbles in your loop, especially right after the noise?

Yeah there are really small micro-bubbles in the loop. How can I fix the problem since I can't see through the tubes because they're black tubing.

Here is what I would suggest - only put power to your pump, nothing else (just in case something comes loose while doing the next step). Then, while the loop only is running, tip your case side to side, front to back. And I mean tip it, like right onto it's side, front. Hell, even roll it right over, upside down. You'll start to get a feel for where the air stuck, and from there you can decide which way of tipping/vibrating the case is helping to dislodge the air. Can I take a stab that your rad is the highest point of your loop in your case? Is there anyway you could run the loop on it's side, with the res upright as the highest point in the loop? If you leave it like that for a bit, the air will work itself out. You may hear a few bubbles pass through the pump now and then for a couple weeks after setting up the loop, but it would be so minor, not like what you are experiencing here.

Thank You for the help and I try those again after filling it up. Even though when I first set it up I did a lot of tipping side to side still I'll do it again. Yes the rad is at the top but the res is just below it. In order to make the res upright I would have to stand the case on its back where I plug in the power cord. Okay thanks again back to bleeding I guess.

One thing you could keep in mind once you get it filled and air free - when it comes time to do loop maintenance, and you need to drain the loop, see exactly how much fluid it took to fill the loop, and write that amount down or something so you know how much fluid to put back in when you go to fill it up. If you go to fill it up again, and the same amount of fluid isn't fitting, that means there is some air trapped somewhere in the loop still. So if you drain a liter from your (air-free) loop, you should be able to fill it all the way up again with a liter.

All right thanks. Though I know it takes 1.5 liters of coolant to fully fill the rad and reservoir thought since there is air I might be wrong.

I'm not sure about the res/pump combo you have but with my xspc res/ddc pump the inlet sits just above the pump and thus when air came into the res it got sucked right back into the pump, I had to use a cut down bit of tube to through the fill port putting it inbetween the inlet and pump so air wouldn't go right back into the pump
