I was thinking about ways to push this beyond the 2.4-2.5Th reported by other users.
One way could be to use a bigger fan and adapter to funnel more air CFMs into the pod.
For example a 120mm or 140 mm fan can push 2-3x air through the heatsinks, while still staying fairly quiet (<25db).
I've seen some s9 space heater designs (skip to page 9) that are replacing the stock 120mm fan with 140mm fan to allow the machine to run quietly without compromising on cooling.

Would like to know from others here, if this makes sense and is worth a try.

That is what I have done.  I created an adapter to go up to a 92mm fan as the airflow increases from 55.5 m³/h for the 80mm up to 78.9 m³/h for the 92mm.  The 120mm could easily be done, just trying to keep these somewhat small, but the airflow would increase up to 102.1 m³/h.  I do have a 140mm fan I could experiment with, but the pressure drops.  Almost everything I 3D print is for mining purposes.

Nice one!! i used a high CFM Acial fan, it is in some of my postings, i will share my results of my testing just needed to do one more … but those 80mm fans made a lot i can tell full speed kept the heatsinks on 37 Degree Celsius and i was running at 725Mhz 3.2-3.4 T and power was strangely flat to about 140W the issue i saw was more on the asic was not keeping up the frequency. but i can tell got interesting results I will post them.
