DIY sealed system

pyropetepete · 28 Aug 2012 at 20:53

I want to use some of the parts i have already to build a nice sealed system. Better than a H60/H80. I need to make something as small as possible.

Parts i got are

Akasa Viper 140mm X2 fans
Laing DDC 18w pump stock top
DT Snipper block

I have 3.5'' between my case floor to mobo. There is a 140mm fan already mounted under the case foor so offering a 2nd within the case is an option only.

I'm thinking of using a bracket on the rad to mount the pump.

Modded top on the pump, G1/4'' and looks nicer along with the performance.

So i need to sort a rad out, what size tubing to use and how to make this one simple system.

Is there a rad that has a bleed on it? My idea was could fill the system and bleed it via bleed nipple.

Any other ideas? Need to be as small as possible

Anyone?

it order to bleed air, you must replace it with something, having a little air is ok if you have a res.

Maybe a combo http://www.overclockers.co.uk/showproduct.php?prodid=WC-017-XS&groupid=962&catid=2133&subcat=

I think the latter (Bitspower DDC Mini Water Tank) might work but i was looking at something more smaller, sealed.

Perhaps a rad with the multi barb option that i could fill outside the build then drain off all the air and seal it up

I'm just a little worried that you won't be able to completely eliminate air from the system and you will have an air bubble constantly going round the system, which might well make noise, especially if it sticks inside the pump.

Maybe have a multi option rad like you were saying but have a piece of tubing coming off it and upwards, that will act as your top up point and visual level reading, but it would have to be at the highest point of the system. But I had quite a lot of air in mine when I started it up and the cpu plate atomised the air bubbles, dispersing air into the water, it was days before the res managed to sort it all out. I think with a well designed system you might get away with it.

Being as you need the bleed point to be at the high point to trap the air bubbles, maybe a Y or T piece with tubing coming off it upwards might work, rather than the rad, depends on whats going to be highest.

I was thinking i could purge the system via a 2nd pump i have on the multi barb option rad.

This will clean out any trapped air.

Once i'm happy with it i can seal it off one side then leave a tube on the other as a res for one more day to be sure it's air free then fit into the system
