One of the reasons I started the tests was because the top rad space on the Phantom 630's isn't very large, only ~55mm.
If you want to run push - pull, you're limited to a 30mm thick rad. . . . . At least without a major mod
There is however, room enough to run 32mm, or even 38mm with a tiny mod, fans above the rad.
I was looking to find out how normal 25mm fans in P-P stacked up against a 32 or 38mm fan in push only on a fairly full thickness rad to see if that would be a workable alternative to a 30mm rad in P-P.
The P-P 25mm fans blew the big thick fans away, both on the GTX and the Monsta.
Edit To Add: I was specifically testing against the thicker fans with good listed specs for cfm and SP in the sub 3000 rpm range.
These fans offer similar noise levels to the 25mm fans and wouldn't be too hard to take on a controller, or for long periods of gaming at high speed.
Now the big fans in P-P is a whole 'nother chapter, but generally . . . .
The airflow was so much greater with 25mm fans in P-P over a single big fan, that I gave up that concept and started looking at a mod to fit a more normal sized rad with P-P fans.
Here's what I came up with:
It works perfectly without any mods to the fans themselves for the XT45, (and others of that size like the EK) and with some mods to the fan corners, it will work for the 55mm Black Ice rads.
The only difference is the spacer lengths.
Still waiting on my hardware from McMaster to arrive, so it's just with temporary hardware atm. It's also raining, so I won't get to paint the mounting plates and the XT45 until another day, but here's a little preview:
