quick question about my setup

[sascwatch]

While doing a quick dusting of my computer today I noticed that my coolant levels looked low (like 5mm) from the top of my EK multi-option re. So I decided to top it off, but when I unscrewed the top off of the res the coolant levels returned to near normal levels as if the system was pressurized and was preventing the coolant from returning to the res. The computer was off when i tried this aswell.

I have read about different ways coolant level can drop, such as a leaking fitting, evaporation, and a very slight amount seeps through the tubing over time.


My loop consists of an HK 3.0 CPU block, EK EVGA x58 motherboard and mosfet watercooling kit, TFC 360 rad, mcp655 pump, EK multi-option res, primochill primoflex tubing, bitspower and TFC compression fittings.

My system runs for about 4-8 hours a day.



How much coolant should I lose over lets say a 3 month period, which is when I topped my res off last, due to normal evaporation and what not?

And, is it normal for the system to have some (very little) pressure in it when it is first shut down?

I also noticed that when I first turn my system on the coolant levels in the res drop a bit, maybe close to 1cm. Might there still be a bit of air in my rad?

your're correct that when level drops when pump runs, air within loop somewhere

this why to have rez @ highest point in loop

for liquid is heavy then air

I barely loose any after system was bleeded properly. If any air still trapped inside radiator or block and may get pushed trough and will show as lower level of coolant.

It's normal that coolant level drops what you start pump if you have some air in res or somewhere else.
