Thermalright TL-B12 Extrem - Fan Noise

The blade design seems copied from the Nidec Gentle Typhoon low-speed version (minus the notches towards the hub the GT has). Unfortunately, this one seems to lack smooth commutation, which the Nidec has. I¬ sure if the non-Extrem version is different with that. It also seems to have more vibration. Out of the box, all of the corners have black rubber, but I just put on the red corner because that&how it looks in a lot of the promo imagery, and I think it looks more distinctive that way. It comes with a set of red and white corners in the box.
