Rad Box airflow

[Delirious]

Im building an external rad box that will sit under my lian-li case.

Is putting the rad at the bottom of the box with the fans sucking air through it and out goin to hurt airflow?

There will be an 1.5 inches of clearance on the bottom and 1 inch of clearance between the bottom of the case and top of the box.

Should i just make it like everyone elses, radiator on side fan on the other?

The biggest issue is that you're essentially creating a vacuum cleaner

haha, yah i thought about that. My room is kinda dusty no matter how clean i keep it I have to clean the front filters on my case every 2 weeks.

I guess ill just do it the 'traditional' way :shrug:

If the air is exhausting out the bottom it shouldn't be a big deal. But I've had a setup with rad on case bottom before that really did require constant attention to keep the filters clear

I clean the filters on my rad box about once a week with the vacum cleaner...
I find that if there is dust in the air... it get's sucked up.

Works as an air filter too huh? :P

My mountain mods case has so many fans i swear i purifies my air :P

Hmmm... Using a bottom->top airflow, you would take advantage of the convection effect from heating the air as it passes through the rad. Not sure it would help much, anyway...

but have fun cleaning the filters.. unless you make them removable...

I built my airflow chamber with some noise reduction elements in mind. The noise has to bounce around before it can get out of the box and into my ears. This works really well at muffling the fan noise (which is three 120mm fans). Nothing revolutionary or original but it works well for me. Airflow is good - no issues at all.

Ideally I should have some 1" thick fiberglass board lining the interior of the chamber to further absorb noise. This was recommended by a friend who is an internationally recognized expert in acoustical engineering (he owns/operates a big international company in acoustical engineering). Unfortunately I was only able to find 1/2" thick fibreglass ceiling tiles. The thicker the fibreglass board the better for absorbing the low frequency noise. 2" thick was actually recommended but that’s getting insane.

These pics are from the earlier parts of construction. I do have a filter installed in front of the intake port at the bottom-front. It gets loaded with dust regularly but I made it easily removable and cleanable so its no problem. Once every few months I take some compressed air and blow out the entire airflow chamber (including the 2 heater cores I use in there) as the dust does build up inside.

I went with a side mounted intake and exhaust, still isnt fun cleaning the filters though.

It looks like bigger is better!
