Did a misspurchase with some fans and need to replace them. PWM controlled preferably, low rpm down towards 500 rpm, less is nice but not required. Pointless with anything above 1200rpm.

Usage will be towards a radiator. Important that they are as quiet as possible. Hence the low rpm.

The fans I got has a ticking sound at low rpm. Beige Noctua fans are not an option due to the colour.

Buy noctua industrial, run them at whatever you like. Corsair ML are pretty good.

Hmm I got a pair of Corsair ML 140 I could connect to a radiator to get sound level on. I completely forgot about that. Hopefully the 120mm version doesn't differ to much.

Noctua fans tend to have a lower low end than most other fans I tried. I built a little arduino setup to adjust the PWM down in increments to see where it would stop spinning.

They also come with the 'low-noise adapter' which is just an inline resistor to slow the fans down even further.

I run the noctua fans on my rads at about 700 RPM

Can't go wrong with Noctua. From my experience their 1st gen SSO bearing fans are actually better acoustically than SSO2 (all their black ones are SSO2), but below 1000rpm you can't hear a thing.

All their new ones are SSO2?

@TJDMHEM: The RGB is turned off if one isn't using the corsair specific hardware I hope.

Not sure, maybe they still use the old bearing in some models. Don't get me wrong, I'm not saying SSO2 bearing makes a loud fan, my NF-F12 is still very quiet at 1200rpm, but the old NF-P12 is almost completely silent.

At 1200 rpm the air flow itself against the rad will make more noise. Or should. Anyhow that is in my experience to much noise for me.

I got loads of the old ones, but oh dear that colour :P

@loonski: I was originally against Noctua's fans with their signature colour, but I might have to eat those words. The NF-A12x25 120mm pwm fan might be the best one... Costly though.

Small update. Tried some old Noctua PWM fans I got. NF-P12 120mm I think the model is. Older, perhaps part of their Redux lineup now, or discounted altogether. Two of them are pretty damn silent at 950 rpm. Damn I regret not replacing the rear case fan. I gotta take out the CPU cooler if I want to replace it now. Which I frankly might do.

Hideous colour though. I should perhaps replace some of my fans in primary build with Noctua 140mm fans.
