With that kind of a setup you might be able to stick a small rad at the top (maybe just liquid cool one of the CPU or GPU) and use the dial to monitor the pump pressure or liquid temp.A 120mm AIO rad doesn't fit inside the radius of the canister. The reservoir(s) are too big. The high air resistance of a rad is also not ideal for using that one fan to blow air through the whole canister. I need velocity so that the GPU fan isn't eating its own excrement.

DPete27 wrote:could you fit three of them more vertically like in the link but exits pointing up, 60 degrees apart, pointing up through a circular plate?I still need to mock up my fan box to test the Bernoulli Principle results for airflow and pressure given the limited exhaust venting. However, I wanted to check on the pressure stats for blower fans, and wow....whereas the majority of "High Pressure" axial fans top out at .635psf, a 90mm blower fan will push 2.5psf. The downside is the tradeoff of CFM and quietness for pressure. Whereas axial fans provide an overabundance of CFMs (more than can be exhausted in this setup), blower fans have comparatively high pressure, but lower CFM. The very layout of that particular blower fan is such that I don't even need to do the Bernoulli calcs. The exhaust port is approximately 2.5 square inches and almost exactly matches the total available exhaust area I can provide at the top of the extinguisher. I'm not sure if 21 CFM is enough @ 43dB though. Thoughts?

I keep bobbing back to the cooling solution from time to time though. Thus far, it looks like the unhoused centrifugal fan on the Mac Pro is about the best I've found so far (except there's no airflow/pressure stats to be found). However, it's prohibitively expensive and I can't seem to find a similar fan design anywhere. Any ideas?

Having just bought a new hammer, everything looks like a nail. 3D print it! You can pick up a cheap brushless motor to run it.
