Xpg hurricane mag fans you can reverse direction blade spins at push of a button

[Mcnumpty2323]

Saw these earlier
Change direction fan blade spins
By pushing a button on them
So goes from clockwise rotation to counter clockwise rotation
And vice versa
In effect can be both an intake or exhaust fan
At push of a button

In my head doesn't seem right
Intake the concave shape of a fan "scoops" air in
If you spins it the other direction
Surely convex won't move as much air?

Looks like the fan blades are slightly different from usual
Maybe that's to help with that?
Be interesting to see actual reviews for these
Including airflow tests

Surely convex won't move as much air?

Correct, there will have had to be some airflow, static pressure or noise compromises to simply make it spin the other way and still work.

So what's the use case for the gimmick?

Doubt it'll be strong enough to blast the dust filters clear.

Will still be interesting
To see actual reviews to see
How much compromise

Could be useful
If you're building in a new case
And want to try different airflow scenarios
Without having to flip fans over
Which isn't always easy to do
Depending on the build
Or buy ones that are specifically intake or exhaust
Plus they're magnetically daisy chainable too
And rgb as expected nowadays

Wow, very clever:

It tells you the specs of normal operation and reverse operation in the bottom right of the video, seems reversing them does reduce airflow slightly and is louder, but not by any massive difference, real world reviews would be good, I bet Lian Li are laying some big brown smelly eggs........no need for specific reverse flow fans........
