Yeah, I could see why you think that. I might make some and run different tests, such as max amp draw, max temp and other things of the sort.
The only reason I want to try them is that Iāve seen them work miracles on different types of motors

Thereās no aerodynamics here. The mass circulating through cooling air is perfectly round and not very good at moving air through the motor, just spinning it in circles. A fan on one side creates a massive low pressure differential and draws a lot of air through. Moving air for cooling is literally what every industrial motor does and anything that involves cooling ever.

Iām already boredā¦ I run mostly direct-drive, thermal-pasted, statorated motors, twirly fans are bullshit to me, I stated it aboveā¦ itās my personal opinionā¦

Agree, twirly fan on a direct drive with minimal vents does not much extra, but a large 80mm squirrel cage fan on a 200+kv motor spinning at a few thousand RPMs is going to draw a significant CFM directly through the stator and magnet gaps, where it is needed the most.

pengyā¦ letās try and answer @JoelM 's ???
he asked āwhatās too hot?ā
and I answeredā¦ āwhen itās too hot to handle comfortably itās too HOTā
do you think that is a fair assessment?
could you perhaps offer the lad numerical aids to answer his question, as to stay at least on the perfiery of topicā¦???

I think too hot to handle comfortably is a good assessment.
Although I frequently run my motors hot enough to not be able to hold them for more than a few seconds. I think long answer is, depends on what temperature of magnet wire insulation was used, what rating the magnets are before they suffer permanent demagnetization due to heat, etc etc.
Usually motor windings are rated to 180C and up, N42 magnets or equivalent can tolerate up to 80C or more before damage occurs, both of which is way too hot for any person to hold in their hand, yet perfectly okay to run up to those levels.

Re: temperature limits
The magnets will start to degrade around 60-70c, and start to permanently lose their magnetism around 75-85c.
The stator can usually handle 120-180c depending on what type of enamel is on the wire.
The stator will always be hotter than the can, because A, the heat is generated there, and B, ther is less airflow to cool it.
TLDR, if you canāt hold your hand on the motor for ten seconds without discomfort, youāre getting somewhat near the danger zone.

So I want to create a board. I am not sure what enclosure to use. I want something that is sleek, sexy, and beautiful. Also what motors, etc do you use. This will be my first build but I want it to look good. Any help is welcome, I plan on using a evolve deck or is someone has a cheaper option for a very similar deck that would be great. What do you think the total cost will be?

Welcome!
If you plan to use an Evolve deck, eboardsperu.com
has an enclosure for it, if not there are many enclosure options for many decks.
Popular deck choices are the Jet spud/Tayto, but the decks are rare now, and Landyachtz evo.

damn, as a first time builder this is super offputting. what the fuck happened? he says connection failureā¦ but that sounds super general. +1 on how to avoid this sort of thing (or should I just āexpectā this as part of esk8ing, as someone else suggests!!!)
Not sure what happened here. All I can say is that the focbox unity he uses is being used by thousands of other without problems. All lacroix boards, kaly boards and bioboards uses them. As well as many on the forums.
