Anyone also thinking the Scythe Slip stream 1200 Pwm is quieter than the NF-F12?
Perhaps I wasn't clear: at least up to 800rpm I prefer the Slipstream, sound-wise.
But the SS isn't an overall better fan than the F12: the Noctua is better built, it is likely more reiiable, it has less samples variance, it has a far stronger support all over the world.
With reference to these facts, the only advantage the SS has is that it's usually far cheaper (here in Italy it costs about the half).
So, whether the SS costs about the same, whether you have to order that fan abroad (and your support will be abroad, in case), IMHO the Noctua is a safer option, even if probably sligthly inferior sound-wise.
Have I been more clearly understandable, now?
At the same speed/temp rise
Check some relevant SPCR reviews: Scythe Slipstream PWMNoctua NF-F12 PWM
Yes, totally. Thank you very much. I've read those reviews, but I asked for opinion because I wasn't still sure which one to go for. I'm going to wait for the NF-F12 for $30 to be available again
Thanks to everybody. I'll post the results once I have my new fans spinning
I'm testing the NF-S12A FLX at 730rpm with the ULNA adapter, and the NF-A14 FLX at 770 rpm using both adapters in serie in order to get the lowest rpm. And I must say I'm disappointed..
I started running them at full speed, and the NF-A14 produced a high whirring and droning noise. (Which is said in the spcr review about this fan)
1020rpm with the LNA adapter: the droning noise disappeared and the whirring noise was lower, but it was still there catching my attention,
900rpm with the ULNA adapter, the whirring noise didn't wore off, it was there, but also lower than before.
Finally, connecting both adapters together the fan is running at 770~ rpm, the whirring noise seems to have disappeared, but it has something that annoyes me, I don't know what it is. But if I put my ear 10 inches away of the front of the case, I can still hear the whirring noise. Maybe that's what is irritating my ear.
On the other hand, the NF-S12A made a humming noise at 1200rpm, but it wasn't as high as the NF-A14 noise at full speed
The noise gradually lowered until 730rpm (with the the ULNA adapter) where it has totally disappeared.
Having read all those reviews about how quiet these noctuas were, all I was specting to hear at 750rpm was turbulence noise/air moving. Maybe, indeed, the NF-A14 sounds like this, or maybe I've came across with a defective sample, I don't know
I tried to explain it the best I could. I hope it's understandable
