H140-x water levels decreasing but no leaks?

Nexus Radical · Aug 31, 2016

From some reason my water levels in my H-140-X are decrease at a unnoticeable rate. But they are since last time i checked the which was yesterday at 9:00PM the water levels have dropped very noticeably for what I am seeing. Still waiting on a new phone but heres what they were using paint.

Before: Red After: Blue

I also think my temps are higher but i could be being superstitious. My max CPU temps from when I've tested them have been 80*c while stressing it so what?
The only reason why i don't think a leak is plausible is because the likely leak areas are all over something which would kill a piece of hardware below them. Apart from one place which couldn't feel any water oozing from it.

Update:

I just noticed that the light inside the reservoir dims every now and then. Sometimes it stays dimmed for a bit. Nothing?

evaporation is normal and that why those can be refilled. I lose like a CUP of water a year in my system.

It also could be the air that was trapped in the radiator and is now out. That is very common.

Judging by how much i lost in less than a day im doing to lose a lot more than a cup in a year. Still normal?

iamacow :

Evaporation from a liquid cooling loop is not normal.

You are either experiencing air being purged from the radiator and displaced into the radiator or you have a leak somewhere.

How obvious should a leak be? Also the levels how changed again! Loosing this mmuch already makes me think a leak, But i cant see or feel any. If there is one its going to destroy either my M.2 SSD, SSHD or My 970 since these are on each side of the tubes.

New levels in Yellow:

wtf? This is scaring me. Im sure my heat levels are rising for my CPU too. Not to much success with my first water cooler i guess.

Likely answer to the drop?

rubix_1011 · Sep 1, 2016

While it is running, open the cap and fill as full as you can get it. Reseal the cap.

Again, this could be air that was in the radiator and is now being displaced into your reservoir. This is a good way to get rid of air since it isn't going to help the cooling loop.

rubix_1011 :

Does it matter what i fill it with. It came already full and i havent opened the cap yet.

rubix_1011 · Sep 1, 2016

Distilled water would be best. You might have to unmount the radiator from your case to allow it to be held upright in order to open the fill cap.

Unmount, orient upright.
Start PC or jump your PSU. This should allow you to see that your reservoir level is a little low.
Crack the fill cap open slowly, there might be a little hiss.
Open, slowly fill as full as possible while running. When bubbles stop, recap.

Don't freak out just yet about leaks, but be on the lookout for drops of water anywhere in your case. Also, once you top off the cooler, keep an eye on the level...it shouldn't go down much or all at this point if you have purged all the air.

Okay thanks. I will do so now with some bottled water. I guess that will do.

Dont use bottled water!!

rubix_1011 · Sep 1, 2016

Bottled/tap water does have minerals which can cause buildup, but since it is such a small amount and the fact that you're already running the loop full of coolant, that would be fine.

If you decide to ever drain and refill it, use distilled water and some form of antimicrobial to prevent growths. Other options would be to use a coolant with antimicrobial properties.

The cap is way to tight. Nothings coming off.

This thing has been a pain in my a**. Maybe if nothing comes up i can return it as defective to amazon. Because boy water levels are dropping for a reason that i wouldnt call intended.

rubix_1011 · Sep 1, 2016

Use a coin or a flat head screwdriver in the slot - it isn't intended to be finger tight, but it also isn't intended to be wrenched down, either.

If there is an actual leak, it has to be going somewhere and there should be evidence of it. When you stop the machine and the cooler shuts down, does the reservoir level stabilize and return to 'normal'?

It's difficult to tell without photos for reference.

iamacow · Sep 1, 2016

If it was leaking that much you would notice it. I'm going to go with air in the rad still. Someone at the factory didn't do a very good job of removing all the air.

Nexus Radical · Sep 1, 2016

The levels werent changing. I texted that before to see if it was just water taking up more space i the tubing. But it didn't, well it did but not by how much was missing nor close. As for the status. I've claimed a refund with amazon. The product wasn't right for me each way, i hated it and the temps weren't worth the money if it was fine. Thanks for the support though!

rubix_1011 · Sep 1, 2016

What temps were you seeing - idle and load? Stock or overclocked? Ambient room temps?

Nexus Radical · Sep 1, 2016

rubix_1011 :

stock 40*c min about 43 stable with highs of 47c. Thats idle stock. Overclocked i was getting better then i started to get 54*c idle around average

Surprisingly i refunded it today and got the money today.

rubix_1011 · Sep 1, 2016

That doesn't sound right. What is your ambient room temp?

Either way, sounds like this is no longer an issue. Pity. I have really enjoyed testing the one my son has...it did fairly well.

Nexus Radical · Sep 1, 2016

about 21c

rubix_1011 · Sep 1, 2016

Definitely does not sound right. My son's i7 2600 idles around 19C and his room temp is rather cool since it is downstairs, but nothing like that kind of discrepancy.

My apologies then...although I'm quite curious as to the actual issue. I really only recommend Swiftech and EK Predator to those looking for a closed loop cooler solution but something that actually performs like a normal watercooling loop (beginner).

rubix_1011 :

I should of probably done more research than reviews but i just brought this with the refund and another system fan:
https://www.amazon.co.uk/gp/product/B01GE0SUXI/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

It was on the 2016 editors choice for water CPU cooling. So i thought cant be bad. Did i make a good choice, May it grant great cooling? I only realised that my case can support 2 x 120.

rubix_1011 · Sep 2, 2016

I would have stuck with the Swiftech or got a replacement.

Those AIO coolers are essentially all the same - the pumps and radiators are essentially the same from one brand/model to another. Very low flow rate and pressure and aluminum rads.
