This is a very nice fan!There are several versions of it (1600RPM, 1800RPM, maybe some more).Beware of Aliexpress clones of this fan! They are not true 12mm, I suspect they are using a 12mm frame with a regular set of blades from a 15mm fan so the blades are protruding quite a bit making the required clearance much larger.That being said, the OG versions of this fan also have some disadvantages, namely motor hum and motor/bearing temperatures, so better have a replacement one at hand.
