Woohoo! My fans have arrived

[Roger24]

I received a package from Greenweld today with a 172x151x51 Comair Rotron fan, and a Japan Servo DC Centaur II 120mm fan.
I tried the Comair fan, and there was quite a breeze when I held it toward my face
I haven't tried the other fan since it came with a 3 pin connector. It's rated at DC24V 11W, is it safe to plug into the mainboard?

Well, there is no 24VDC inside your case. If you want to run it at
12VDC you should NOT plug it into your mainboard. IT will
burn out the fan header. The only safe way to use it is to
connect it to the PSU thru a standard HDD power connector.
Test it before you deploy it.
