I'm fairly new to the watercooling scene, having converted my PAL8045 system to watercooling (specs below in sig) back in January of this year.

I have an inverted "T" fill tube for my closed loops system. It's about 18" long (hey, this Supermicro 760A case is HUGE).

The funny thing is, I'm loosing about 1 1/2" of level in the fill tube every four days or so. I have NO leaks that I can find, none whatsoever. Every single connection is secured with a screw clamp.

I'm using the 1/2" ID Silicone tubing from Dangerden.. is it actually somewhat porous??

I'm very positive I don't have latent air pockets in my system, as I was very thorough to fill it underwater, and invert/twist/rotate the entire system components to evacuate all air bubbles.

And my temps are great: 32C max at full load.

So - where is the water going???
