If we want to briefly return to enjoying fun builds in this case, I completed my 3xNoctua AA12x25 build!
Step 1 was acquiring another TX240, this time in the standard configuration. Got that and two more Noctua's from Highflow.nl in the Netherlands. Shipping to Canada was expensive but super fast. Only took 3 or 4 days.
I then proceeded to sand down the fans in order to have them fit on top of the radiator. Probably took off 3mm, all on the intake side. Fan hub protrudes front the frame but does not rub on the radiator at all - no mods required to the radiator.
Then it was time to drain the loop...again lol. The drain port only gets so much out so I have this fun cup strategy I have come to love.
Then built it all up for some open case tests, including the side radiator.
With the case open and both radiators installed, I ran some tests. REMEMBER this is with the case entirely open so can't be directly compared to the closed case tests for the final config. I have found that closing the case usually pushes everything about 4C higher, so keep that in mind when comparing between the before/after thermals.
Heaven 4.0 for 30 minutes, with average values from the last 10 minutes of the test (note, this is the method for all future values you'll see too)
So I decided that this new top radiator setup would let me eliminate the side radiator entirely. This would net me a system that is much less complicated, much easier to service, quieter (fewer fans in total and an elimination of the side fans operating with only a ~2mm gap), eliminate the small GPU side panel bulge my radiator was causing, and let me see that nice EK GPU block.
So I tore the loop apart again and rebuilt without the side radiator. Final photos are below! You'll note that I'm not using the radiator bracket at all as that allows for another ~1mm or so of clearance and the radiator is wide enough to support itself on the side struts without the bracket.
Thermal results using same methodology as above, but this time with the case FULLY CLOSED:
NF-A12x25 fans are just so quiet and efficient, even though they're running at higher RPM than any of the fans were in any of my previous setups. For similar systems (3080 and 5600x), I don't think I can recommend the side radiator anymore.
It still requires sanding fans (unless you can find a thinner GPU block than I did) and even then still might cause a bulge in the side panel if you actually leave enough gap for half-decent airflow. I also think that that small airspace on the GPU side makes the fans much louder than they otherwise would be.
So at the end of the day, if you're going to go through the hassle of finding a TX240, sanding fans, and forcing a radiator into the side chamber to cool a 3080 and 5600x....don't lol. Sand 2 full size Noctua's instead!
Happy to answer any questions guys!
