Draining loop - Page 2

post #11 of 16
Holy tubing Batman! I would adjust the loop order as Andrew suggested. Again it doesn't really matter what order they go in, the water only varies by a few °C as it goes through the loop (no 4 in my sig).

Reduced tubing length will not only make your rig look neater but it will also improve flow rates slightly, which in turn will improve temps.

As for a drain port there are several options already covered. One that hasn't been mentioned is to put a QDC between the GPU and the front rad. When you come to drain simply disconnect and use a spare QDC fitting to drain. A bit of an expensive option but neat and effective.

Bad idea. It is too easy to run your pump dry doing this which can destroy the pump in seconds. If you must do this keep a very close eye on the level in the res and be prepared to shut the pump off before it runs out of water.

A pump will be able to run for several minutes without coolant in it at all...plus the last amout that enters the pump stays in the pump so it still is lubricated. You seriously think spinning it dry for 10 seconds at the most will ruin a pump?

Probably not in 10 seconds but who knows? Either way they are not designed to run dry. From Laing's DDC manual:

Even if it does not destroy the pump the first time, it may well cause some damage. Do it often enough and you will have a broken pump. Might be worth the risk to you but I wouldn't recommend anyone try it.

I am working on a build myslef, and I let you know if you want to when it gets done. But what i have come up with for me, is I am putting some quick disconnects in, and the way I am doing it, it will end up seperating my loop in to 4 sections when I disconnect. 1 will be the res, one will be the rads, one will be the pump, and one will be the blocks, and this is with 4 QDC in a loop. well then I got 2 extra QDC ends, that way when I have the items out of the system I can put one on each end of the section and tip over and drain out the water away from the MB or Case. But you would have to do that, just put 1 QDC in your loop and then use the 2 ends to open the line and hold one side if the hose up, and the other in a bucket. just an idea you could think over and make it work out some how.

PS the reason i am breaking my system into the 4 sections is because my MB sets high and horizonal in the case. so it makes it easier for me. because a drain port will not get even about 50% the water out. this way I can just dump the effected section and work.

I didn't know about the Qdc. I got a bitspower t atm. Ill use the t for a few months then ditch it when i change my tubing color and put new fittings.


How much shorter can i make the tubing length?

I know i have extra by the res. That's so i channel the reward out and fill it up.

Thanks
