Adding a Drain Line to Exciting Loop

Avathar77 · 28 Jun 2011 at 01:45

So this is my current loop now
Res/Pump-> CPU block -> Top RAD -> GPU block -> Front RAD -> Res/Pump

I was thinking of adding a Drain line for the convenience, Using a "Y fitting" bitween the Res/Pump and CPU Block, and having a Ball valve at the end.

Would this be ok?
Will it effect the pressure or performance of the loop?

What about a QDC? (quick disconnect)

It will not affect the loop flow.

But you need to turn the fans round on your rad

I have 2 sets of QDCs connected to the GPU as I may remove the GPU more often.
Are you saying I can use QDCs to make the loop drain?

Which RAD? Top or the bottom? I am guessing Top? Is it because fans are pushing "hot" air through the Top RAD?

Ye the top rad

have the fans at the back blowing out and the one at the bottom as well. Rads need to suck air from out side your case for best temps

Reason for not doing the top rads like that is because I dont have dust filters for the big boy fan. I have to clean the front dust filters every 3-4 weeks!
How ever I might just try it

Currently my Highest CPU temp is 28 Idle and below 50 @ load(with P95/IBT/gaming in BFBC2) and GPU temp is 30C Idle and never goes above 40C @ full load(furmark/BFBC2) all this while room temp is around 23C
All RAD fans running around 900RPM.

But this is not the case since yesterday

My room temp alone is 28C and CPU idle is 36C! GPU idle is 37C.
Haven't tried gaming yet :eek:

A few people run a Y or T fitting to be able to drain loops. I expect that there would be some turbulence in the water round the fitting but shouldn't affect the flow anywhere near enough for it to be a problem.

As for the fans, it would be better to run them so it pulls cool air into the case but if your case works better as an exhaust and your temperatures are ok leave them as they are. Remember if you are watercooling your cpu and gpu that your two big heat sources have been removed from inside the case.
