Played around with this idea back in 2018 but couldn't get it to work. Was recently thinking of upgrading some components and saw there are some products out there that might make it possible to fit 240mm's worth of rads into an A4-SFX and create a custom loop for both the CPU and GPU!
Basically just looking for a gut check to see if people think this crazy idea of mine will work, or if there are some obvious red flags I'm missing.
The basic idea is to use two of the Dan-designed 120mm AIO brackets to create a "Cooling and Power" sandwich block in the front of the case, isolated from the cpu/gpu zones. Using pairs of Alphacool ST20 HPE's, Noctua A12x15's, a bunch of Koolance low profile 90 fittings, and two HDPLEX 250w PSUs, it seems like there is just enough space to fit it all in. Would be using a ModUltra LOBO as the pump for the loop, so I don't need to find space for that as most other custom loops I've seen have needed to.
My main concern is fitment and heat management. There's ~4mm gap between the rad fans and the HDPLEX units, and almost-literally zero space between some of the Koolance fittings and the PSU's (if there's anything incorrect with the CAD files I'm using, or variance in the physical parts I'll be in trouble). I'm hoping that by having the 92mm fan under the PSU's/Rads that will be enough to pull the hot air out and way and I'm not just blowing furnace-hot air from the radiators at the HDPLEX's.
EDIT: Adding images which helps visualize the concept.
