So Ive been running the loop for around a month now and the water level started dropping a little so I filled the res a bit more but slowly but surely its still been dropping and has dropped about 1/4 of the res so far, doesn't seem to drop when computer is off only when running. I did a paper towel test on all the fitting and cant find any leaks.

I'm slightly concerned but is this just normal evaporation in loops?

Its getting into summer here which wont help very much either but shouldn't be a big factor.

Is there anything I can do? Is this normal?

Thanks

Evaporation happens. Make sure the top to your res is tight, you will see condensation on the inside of your res if it is. If not it is letting water out of the loop.

That ^ Most connections in modern loops are idiot proof (not calling you a idiot) but it is the obvious that is usually at fault like a untightened filler cap or slightly open T line filler valve. You will have to top up the water every so often even if it working perfectly. I check mine about every 3 months and normally have to add a drop.

yes there is condensation at the top of the res, that being said I have a line coming out the top as a fill point thats plugged but only with a threaded plug because I didn't think to order a proper plug but its still secure.

Thanks guys Ill guess I will just top up when needs be then.

On another note how ofter do you guys change the liquid in your loops and do you pull apart all your blocks and clean them at the same time or just re-fill?

I just fill the loop, cleaning everything is too much work. As far as changing the liquid, do it maybe once a year? If you use a biocide you shouldn't need to change the liquid at all. Maybe change tubing once it starts to degrade but the liquid shouldn't need changing.

And the tubing should not need changing for a good few years unless your doing something stupid like cooling 2 graphics cards and your cpu on 1X120 mm rad and fan. For the tubing to start to degrade prematurely it needs serious temps over a long period of time.

You will have water drop no matter how tightly you cap the res or fillport. It just happens, and the tubing that most watercoolers use is in fact permeable. But it's not at a rate worth getting alarmed over. If you have air in your rads (which you almost certainly do) then you can expect to see a marked drop in res levels when your pump is running. This is normal, and really only correctable with more work than is worthwhile, unless you have Thermochill rads (you don't).

As for everything else, I change coolant when I re-plumb my loop, which is usually concurrent with an upgrade to a new platform, or GPU. That's also a good time to flush your rads and clean out your blocks. I generally install new tubing at this time, as well. I don't think I've ever gone more than two years without such an upgrade.

That. Usually I don't clean things until something is due an upgrade, or has to be pulled out or whatever.

All I usually do is add some vinegar to the loop, let it run for a few minutes, then drain it. I haven't bothered taking apart blocks (yet).

Does anybody know if these supposedly sealed loops like the H-series coolers also lose water over time?

They probably do, at least in theory. The only sealed loops I've ever handled have had extremely stiff tubing, and I suspect that it's probably made out of a less-permeable material than the plastic used in R3603 and other popular WC tubing. I would also wager that whatever those loops are filled with isn't pure water, but is something with a heavier molecule.
