Project: External Acrylic Radbox
- Thread starter fornowagain
- Start date
Given the choice of push or pull I'd choose pull. Fans impart not only forward but rotational momentum to the air. Placing the fan in pull helps reduce the rotational element across the radiator matrix, improving flow. I'm careful to seal the fan edges to keep the pressure up, I want the air flowing over the core not the sides. Its a technical vanity, in practise there's not much in it. One improvement would be a shroud to move the fan away from the core and remove the dead spot directly behind the fan motor. I've tried lots of configurations in the past, even 6 fans on a PA120.3 for overkill and tbh its not needed, the open PA design works well with a single high pressure fan (per 120). What's more important is the choice of fan for the application. It can get quite involved.

I mentioned the cpc quick release at the start, its not apparent what the do. Here's a pic (wallpaper not my choice btw) of the radbox connected to my PC. They are brilliant connectors, a drop of fluid loss and hardly any flow restriction. Just click the button and they separate and seal.

Very nice job, great for when/if you ever change your case etc as all external and definately going to cool whatever it needs to!
A custom case next to that would look sweet

Very nice indeed. I am planning to do something similar with black opaque acrylic. I was thinking of mounting the fans on the top and back though for a pull system. I was thinking it might be slightly quieter this way, also I can use more fans than rad space (i.e. 6 or 8 fans for a 120.2 and 120.3), so can turn them at a lower speed, or higher speed if I am benching

Can you tell me what PSU that is?

Nice job
I like thoses quick connectors, been toying with getting some to replace the Zalman ones I've got.
The Koolance ones look the business
The Eheim ones are the budget choice
and now these CPC ones offer the best flow.

How much spillage do you get with those connectors? I've just spent the last hour (while I should have been working; oops 
) looking at the CPC website, and they seem to think the connectors you've used are both valved; but not spillage free?
