Recently bought a Noctua NHL9i, admittedly I did not do the appropriate research ahead of time before buying the fan, and turned out the cpu cooler didn't fit on my cpu, it being a AMD FX 8300. So, at that point i wanted to get some usage out of the fan for the time being, and noticed it was the same size as the case fan that came with the system. So, i took out the stock fan and put in the Noctua. When i was behind the tower while it was running the other day, i noticed the Noctua wasn't running, so i opened it and took a look at it. Turns out the Noctua only spins while the system is booting, and then it refuses to spin. The stock fan requires 1.6 watts on a 3 pin psu to run and the Noctua needs 2.52 on a 4 pin. Any suggestions on what to do to either fix the Noctua for use as a case fan, or anything else?
