T-line/bleeding question

Patrick_ · Jun 7, 2005

Well, my watercooling setup has been running well for a few days now. Idle 27C, Full load 29.5C. I'm very pleased.

Now, I have a question though. When the top of my t-line (where I fill) is not plugged, and I turn on the pump, the water in the tube on the top of the t-line falls. When I turn the pump back off, it rises.

Now, when the t is plugged, the water falls only a little bit. My question is, should I plug the T when the pump is on or off? Which do you think will be better?

If you are doine bleeding the system close the T-Line.

as it was said before if your done bleeding you can plug it. Don't worry about it pretty much normal

I've never left my T-line open for long-term bleeding. I don't see the need and it just invites coolant spills which are a pain to clean up. I do a pretty good job of tilting the case around to get the major air bubbles out before a final coolant top-off then put the t-line cap on with the pump running.

That answers my question, plugging the -line with the pump running. I've already had it capped, but I capped it with the pump off, and was wondering if I should do it otherwise. I thought I should because when the pump is running, more water gets in to the loop, so I should cap it with it running.

Thanks!

I normally put the cap on when the pump is running more out of convenience than anything else. I'm not going to turn off the pump and/or computer just to put a cap on a T-line. It should not make a difference if the pump is on or off. My main concern is preventing a coolant spill. BTDT and the cleanup wasn't fun. I guess keeping the coolant from getting contaminated is a worthy secondary goal.
