SHL Evercool 60mm 6cm 60 x 60 x 10 12 Volt PC case Fan (PWM)

Got this for my QNAP TS210 NAS when QNAP tech support said they couldnt help with a fan failure and recommended that I buy a new NAS instead! Rubbish support. This fan is better than the original and works perfectly.

Good fan but flimsy construction

Started making noises suggesting imminent failure after just a month or two. Ordered a second one to replace with, and same thing happened. Unfortunately it seems to be the only PWM fan at 60x60x10 mm on Amazon. Good functionality, but terrible quality.
