TY-147 buzzing noise? - Page 2

post #11 of 16
Do you have PWM on your motherboard? Like CPU fan socket? Would be good to see what the fan does running on PWM at lower rpm.

Yes I do, CPU_FAN and the SYS_FAN2 weirdness which I'm sure if it's truly a PWM since the manual descirbes the fourth wire as "reserved"... wth.gif

I'd need to replace the Noctua with the TY, I'll post back once I've done it. smile.gif

The TY-140 is basically a 141 with a different bearing. The TY-141s ball bearing is much smoother.

That's not the only difference. They they TY-140 was first so the TY-141 is based off of the TY-140.

I assume the TY-147 has same design as TY-140 because it is same motor and bearing. TY-141/143/145/140 are ball bearings. TY-140/147 are Enhanced Hyper-Flow Bearing (EHFB).
People I know who have used both the TY-140 and TY-141 and prefer the sound of the TY-140. I've compared TY-140(EHFB) and TY-143 (ball-bearing) and I prefer the sound of TY-140.. But honestly inside a closed case I can't hear any difference.
