Radiator cabinet = quiet ?

post #1 of 6
Thread Starter 
Hi all, any thoughts on this design ? A couple of 200mm fans in front and an open rear. Waste of time ?

Well, for starters, I cannot exactly see where the air will be coming in or going out. I don't see any kind of circulation at all.

I reread your post.


Being open in the rear may or may not be counter-intuitive to your wanting a silenced box.

Hey, thanks for the reply. You make a good point. How about this ? Would the 2 intake and 2 exhaust 200mm fans be silent ?

(P.S. I'm thinking of lining the inner cabinet with some sort of acoustic foam)

While I've no experience in building a radiator cabinet, my limited research and intuition led me to come up with the following design for my radiator cabinet for a build I am in the planning stages of. My Corsair Carbide Air540 will sit atop the cabinet.

Cabinet is solid sides and top and open on the underside. Raised about 2 or 3 inches on feet.

360mm x 360mm HEPA air filter slides in on runners from the back of the cabinet sealing the bottom of the cabinet. Can be slid back out for cleaning. Above that will be a 1080 RAD with 9x 120mm fans in pull configuration. Sealed compartment for pump with access hatch. Above the rad and fans will be a series of baffles treated with sound absorption material like the inside of a speaker. Leading to a vent slot at the back of the box for exhaust.

ie. no need for additional intake or exhaust fans except those on the rad itself. Intake is under the cabinet at floor level which reduces directional sound from the rad fans pulling air in, as does the HEPA and RAD fins themselves. The air from the rad fans has nowhere to go but out the rear vent slot via the internal treated baffles which cut down on the amount of sound escaping the cabinet via the exhaust.

I'll try and do up a simple sketchup model if you are having trouble visualising.

I get the overall idea, thanks for the reply. I am having trouble visualizing the exhaust chamber as well as the pump/res placement.

Like I said, the proximity of the fans to the floor intake, the HEPA filter and the actual fins of the RAD should mitigate the sound of the intake. The exhaust via the acoustically treated channel formed by the baffles works on the principle that the sound waves from the fans have to bounce/reflect significantly more times to get from the rad to the vent slot. Every reflection/bounce against the treated surfaces reduces the energy of the sound wave and be the time it reaches the exhaust vent it has been attenuated enough as to be inaudible or nearly so.
