Dual Rad Config Advice

So I got an AZZA Fusion 4000 for free and I want to make it my folding rig. Max size rads that fit up top are a 360 and a 480. I need to figure out a good combination to decrease the amount of tubing needed so I thought about Swiftech's Stackable rads. They are EOL so I figured I could pick one up cheap (they are only $47 on Swiftech's website). I want this one because it is a more affordable radiator and it has 4 ports to accomplish what I want.

So here is the config I'm thinking of. The bottom rad is the MCR320-QP-STACK and the top can either be a 360 or 480.



Here you can see that I just used 2 BP plugs to plug up the ports I don't want to use.


I'm not sure which way the water should flow for max cooling or how the fans should be oriented. In my head this should work. Just like you would do with most GPU blocks right?

Thanks in advance for the input.


Forgot to say there is a 120mm fan at the back end of where these go. It can be inlet or outlet. Not sure what would be better.
 
Wait... you are planning on mounting fans to the radiators themselves right?

Im not sure I understand your fan question. Can you link us to the case you plan on using?

The best thing about the stackable rads is you dont HAVE to stack them unless you want to, but at least you have the option.

Edit: I just reread your post about the fans, I misunderstood lol.

I would say you should be pulling air through these and out of your case. Mostly for dust. Believe it or not, pulling in the cold air from your ambient, vs removing warm air through your case is minimal temp difference.
 
I did link the case but here it is again: http://azzatek.com/csaz-4000-gallery.html


Yes the top rad will have push or pull under it
The bottom rad will have both push/pull
The back fan can pull air in or pull it out. I'm not sure which way to orient the fans.


So what your saying is that I should have the bottom rad push/pull up and the rear fan should push air out but what about the top rad? Push up and out?
 
Argh, I really wish that there were better internal pics of the case.

Sorry I missed the link, I am at work and only skimming these posts for now.

As for the rear fan, I would slap a filter on it and have it push cool air into the radiator "sandwich"

Im searching google for better pictures of the mounting location for the radiators that you plan to use, then I can give a better idea for your application.
 
Ok, so I saw better pics of the "Rad Box" design on the top. Assuming that you arent planning on using the drive bay, or the PSU connection up top. I would say that you have all air moving from bottom to top.

So the bottom radiator has push/pull fans moving air into the top area, the rear fan moving cool air into the top of the case, and the top radiator should have fans mounted to the top pulling air out.

When fans are setup as "Pull" they cool slightly better as it sucks the air through all the fins where as push sometimes pushes air out of the cracks, but the difference is marginal. Not to mention it is easier to mount the radiator when screwing in to the fans as opposed to the radiators.

Also, since these stackable radiators are the QP version, there are I believe 16fpi which means you can use medium/slow fans, which will be nice when it comes to noise levels.
 
Well you can't fit fans on top of the case under the top panel so the top rad has to be push up and out.
 
I wasnt meaning under the top panel. Im refering to the way you have the fans mounted now, just attach the radiator to the fans.

I think where we are confusing each other is the orientation and termonology of push vs pull.

If the fans are on top of the radiator and moving air through the radiator by "pulling" it from the side that has no fans, that is refered to as a "pull"

If the fans are mounted to one side of the radiator and are moving air TO the side with no fans, that is refered to as "push"

Where they are mounted in the case makes no difference to push or pull. Its all in reference to the radiator.

Here is what I mean by "pull"

Ok. You can't see it but those top fans are on the bottom of a rad. I guess I could change the orientation of it and do push pull on it as well. IDK why I didn't think of that :confused:
 
Ok, I didnt realize there was a radiator on top of those fans. You have the perfect case to do push/pull on both radiators. Are the fans moving air in to the case right now or blowing air out?

Ive never seen this case before, and its quite user friendly when it comes to water cooling! nice score!
 
As of right now all fans are going up and out. The rear fan is blowing air out of the case.

I currently have some cheap Yate Loons on there but I was thinking of switching to Aerocool Sharks.
 
Dont under estimate the Yate Loons. I run Yate Loon and they are the best bang for the buck. Very few fans can touch them in terms of price/noise/performance.

I would make the rear fan an intake instead of an exhaust, this way it isnt stealing any air from the radiator below it before the air gets to the upper radiator. The difference is probably not even measureable, but it cant hurt to turn it around.
 
Ok. I have a shark fan there which moves way more air so I think that will help out alot.

Thank you for all your help!


Now.... if only I could find a MCR320-QP-Stack lol.
 
What is the part number for the Yate Loon you have? There are 3 models. I would recommend the Medium speed fan (it has an M in the part number) if you have the L letter in the code, then i would upgrade. Especially if you arent doing push/pull on both radiators.

I know these are a bit more than you quoted on the stackable Swiftech, but these do meet your needs, as long as they dont break your budget. The way I see it, you really only need one of these, not 2 in order to do your setup.

I have an XSPC and Swiftech radiator in my setup and the temps are WAY WAY low... so dont worry about mixing and matching radiator brands .
 
The only other rads I noticed that have that design are the ones I already linked to you.

The Yate Loon fans you have are the High RPM 2200 RPM version... they move over 80cfm of air, but are pretty loud. If you dont mind the noise once you add 9 of them, then go with the yate loons... if not, then get the medium 1650 rpm versions. If you go with a low flow optimized radiator, you can go with the 1200 RPM Yates which will be almost completely silent.
 
Everyone says they whould be loud but they are really quiet. I tested the 18 i bought all together and they were super silent. Well I mean they were way more quite than my Xigmatec fans on one build and the Aerocool Sharks on another.
 
Do them in parallel instead of series. It should reduce restriction and increase performance in that configuration. :)
 
Do they have to be the same size for parallel? I was planing on using a 480 for the top rad.
