It's amazing how far people will go to avoid admitting they made a simple, no-big-deal, mistake. And instead of doing so, they just dig themselves in deeper.
No, you didn't specifically say "all fans in the world". You just implied that by saying, said, "
fan motor mount brackets are always to the... ...exhaust side." You didn't say "most" brackets. You just said brackets. You didn't say "usually", you said "always".
This isn't a casual chat down at the corner pub. This is a technical discussion. We need to be technically correct when providing technical help to those seeking it.
Then, when I showed how your blanket statement was false, to include providing a link to a
PC case fan that demonstrated you were incorrect, you still assert you were right - "unless" the product is marketed as a reverse fan. LOL.
What if the fan is no longer in the packaging - as seen
here? Does your method work then? Nope!
Perhaps you are not aware that the products marketed as "PC case fans" are not used exclusively on computers. They are in fact, simple "box fans", the same used in many other electronics, but packaged in containers that say case fan on them. So you are correct to say that ceiling and window fans lack relevancy here in a computer tech site, but then you didn't specify "PC" case fans. And, of course, I also included a PC case fan to illustrate my point.
I did not put words on your keyboard. You made a blanket, "
absolute statement". And like all blanket statements, it was wrong. And yes, I fully understand the irony of that blanket statement too.
The technical truth is that
most case fans are designed so the air flows out the mount side of the fan's housing. However, since some do not, it is best to verify first. This is most easily done by looking for rotation and airflow direction arrows embossed on the housing. Or, if no arrows, by powering up the fan and feeling for air flow.
It was a simple mistake, Zack. No big deal. We "all" make them occasionally. We're "all" human. Or "most" of us are anyway!
