Noctua has 3 pin or 4 pin fans?

[PeteRoy]

Can anyone please tell me if Noctua coolers use fans with 3 or 4 pins?

Also, do you know what good coolers come with 4 pin fans?

Thank you.

4 pin as in pwm ? or 4 pin molex

 

[PeteRoy]

4 pin as pwm yes

The NH-U12P HSF comes with the Noctua NF-P12, and those fans come in 3 pin with a 4 pin adapter. I'm not familiar with any other of their heatsinks, but from what I've seen, most HSF's come with the same 3 pin w/ a 4 pin adapter.

the post mentions the scythe slip stream which i hear to be a decent fan outside of the sleeve bearing, so you can just stick that on a cooler that doesn't always come with one (e.g. TRUE). If anything you can always get a 4 pin adapter for the fan on the heatsink.

Hi, i'm new here, here is the link about Noctua:

Hope this helps.

Why expensive coolers like these come with 3 pin fan and not the PWM 4 pin?

I don't get it.

Just had to return this fan - Box says 3 - 4 pin adaptor BUT - It is a 4 pin Molex !

The fan itself is only 3 pin- Try the Silent Eagle or Akasa Apache

ahh mistaken . sorry, i guess you have to buy pwms as they are

Just curious, what are you hoping to gain by using PWM over a standard 3-pin?

I don't know much about that

But why not have PWM? If I buy a fan that costs 100$ I think want to get every piece of technology available.

an extra fan slot on your motherboard

Having just purchased a PWM fan to use on my P7P55 motherboard's CPU fan header (only PWM controlled, no VDC control through software/BIOS), I understand why PWM isn't the greatest thing. PWM has a high pitched squeal/whine associated with the fan control circuitry. The SPCR forums are full of posts saying that PWM fans exhibit this behavior. I ended up plugging in a low rpm quiet fan into the CPU header for my exhaust fan and plugging my fancy new higher rpm PWM fan into the chassis header on my motherboard to get DC control of the CPU fan so that it would ramp up with temperature.
