Cheap enough to replace, but I have a feeling these won't last for 5 years+ like the ball and fluid dynamic bearing fans.
Ball bearings get louder and louder as they wear out as well...but ball bearing fans are generally louder at low rpm, I think.
Papst fans seem to be of good quality, maybe I should order a few... don't got money now but maybe in the future (iany isn't going to be happy )
