those mini blower fans can go to hell. I got around it before by opening up the chassis a bit till I got good air flow on a zippo lighter with a normal fan
but for a dryer IDK
those fans are like pumps that push air through high pressure drop things. But they sound intolerable. You need to remove air flow obstructions.
What is the purpose of that grate?
Because you need to look at it from the standpoint of a plastics manufacturer:
1) do the vents really need to be like that or is it because its easier to make in a mold? Perhaps otherwise it would need to be made out of better plastic.
2) do the vents really need to be like that or is it because it would require reinforcement of some kind (structural)
3) did anyone even think about why those vents are there or is it because they wanted it to look cool (chassis are a MASSIVE marketing hype). I had this product I used to work on with a trendy chassis and it made any redesign a fucking nightmare. the 'industrial' version, they put the same shit in a normal box and it worked the same and passed EMC no problem and you can add stuff. awful design work on that. The "appealing" one leaked so much EMC and had such dodgy thermal behavior and cable routing you wanted to tear your hair out even if you had to open it. It was a flimsy mitered metal clam shell thingy. fuck it.
4) does it need to be a small amount of odd holes or maybe a mesh would work, but again thats a extra part you need to screw on. unacceptable for bottom line
5) crazy intake ducts like a engine. for high performance engineered air flow the future is
NOW people
be skeptical . It is designed with ALOT of work to make it look a certain way, but it often leads to insane shit, like blower fans that run 24/7... their often not more clever then you, apart from the fact people might click it easier if it looks like some space office shit.
my guess: their going for the high tech 'book' look at bottom dollar. expect nonsense
