Total Noob Question - Blowback from res (and design)

zeegy · 17 Sep 2015 at 15:23

Hi all,

Sorry for the newb questions, but this is my first WC build since probably my AMD Duron days after getting scared off due to a cracked block.

The diagram is the right way round before you ask, I am using a lian li v1000 chassis which has the motherboard inverted.

I have ordered all of the parts that I believe I need and I think I am ready to progress with the build.

After some investigation I read that it was advised that a drainage tap was added, so I have decided to add that into my design for easy maintenance and kit changes. As I have a place to hide it, it makes sense right?

Am I stupid here, but during the filling process (and bleeding the system) isn’t there a very high risk of coolant creeping back down the hoses and exiting via the fill-port of the reservoir? I see so many systems where the pump and res are near the bottom of the case… therefore, why does this not happen?

Anyone?

the way youve got your layout will be fine m8 when your filling the pump pushes level down ive never had it come back up pipes and out of fill hole also if you havnt got one already id consider a fluid temp gauge so you can keep an eye on what your loops doing

inline temp gauge has been installed.

I have been having some blowback surprisingly. but only 10ml or so at a time.

I am redoing my loop, i cannot see the res very well, and I bought opaque hoses. there's no real way i can be sure the system is running ok (fail)

Therefore, i will be re-doing the pipework with clear tubes.

Would i be better off reversing the loop so that the fluid flows down rather than up?

I have my loop flowing down first time I've had it this way and was surprised how much easier it was to bleed didn't tAke long at all hope that helps

I suspected that this would be the case, thanks for the info - I'll be sure to try that.

no problem m8 i got the idea off mayhems to run it this way round from the sticky about mayhems stuff If you turn the top ad around so the ports face the front and go from bottom rad, GPU, CPU top rad, res, pump -> Back to bottom rad, youll find you use less tubing and it will cool the same. Having a rad inbetween the gpu and cpu will make no difference in temps especially once your system reacheas equilibrium. Youll allso find its easier to bleed air out of the system and if any thing you may find a slight (abit only .05 to 1c) improvement due to better air removal.

Alex,

Just wanted to follow up and thank you for your advice, clear tubing arrived and i reversed direction of the loop, going down first.

This bled so much easier on my small res I cannot express the difference. I am now in the leak-testing phase.

hi yes i couldnt believe how quick it bled the air out so simple after years of shaking case around for ages to shift it all
