HP gear had best-in-class specs and stability.? As parts inevitably change characteristics with temperature, the high airflow made the best of it by minimizing hotspots.? If you are always going to operate at 20C and maybe accept pushing the edges of the specs, you can go with less flow.
I have a load bank which had a fan louder than anything else I own. However, I rarely if ever need to run at full power.? I found a size compatible fan which is temperature controlled with an external sensor and mounted the sensor on the main heatsink.? The unit is far quieter but at high load the fan picks up speed a lot to keep things cool.? Some newer fans have blade designs meant to keep turbulence noise much lower.

My bet is they were all working from the same, kinda horrible, environmental specs, e.g. 55 ambient temperature. That, more often than not combined with linear PSU, calls for Real Fans[tm] ????
