I recently built a Dragonburner v8. Because I print a lot of PLA, I wanted maximum hotend cooling and decided to compare a few different fans.
To do the comparison, I installed the fan, set the voltage, and then ran a MPC tune to determine the steady state consumption (at 208C, part cooling fans off). I used a Revo with a HF ObXidian nozzle installed. Here are the results:
The Honeybadger 3010 was the best performer, however on my setup it created a very loud howling noise, so I chose to run the Sunon instead. This seems to depend on the exact geometry of your shroud / heat break. The GDSTime was also balanced worse than the others, creating quite a bit of vibration. The Delta 2510 was mounted with an adapter found in the Dragonburner repository.
This test is not perfect, as the goal is to cool the heatbreak, not heater core, so smaller fans are likely unfairly penalized. However, I think the relative ordering is probably still correct.
