Still, it isn't L8/E8/E9/Modu87+ level however. Good thing is they don't tend to speed up too much under load.
Most of the time, they all use Globe fans.
Same with the Rosewill units; so the fan speed & noise is about the same between all of them. Though, those with stamped grills are a tad louder in my experience.
Still, it's better than some other units on the market.
