Got you. So in the absence of being able to switch the fan off, your advice is to get a fan with a really low RPM capability. Looking at the data on this site, though, I would expect the Phantek at 600 and the Noctua at 350 to be similar in audidlbe performance, with the former moving more air?

And you're saying that the benefit of the Noctua is that it can run as slow as 350rpm vs the 600 in the Phantek? That is a good point if I am understanding you correctly.

Can you control at what point it goes down to 350?

Because as I write above, I want to be able to do three things:

1. Turn them off
2. Run at 600rpm
3. Run at full

Depending on what I am doing. The system will be ok with no fans, but just want to turn them on when playing a game or editing photos or video.

As far as I know the relevant headers works when you pair them with voltage controlled fans... Yes, modern motherboards do allow control of 3-pin fans as well as 4-pin PWM fans. However the issue is how much control. For example PWM fans usually can be controlled for the whole of their speed range....

If you have not got them yet I would suggest you consider the Noctua NF-A14 PWM as a replacement. Whether the OP can replace those Phanteks, there should be no need of PWM fans, with that motherboard. Something cheap and good sounding like the Prolimatech Vortex (either Blue or Red), or the Antec T...

So all your questions are just hypothetical ones?

Well, its all pre-ordered, just waiting for it to arrive!! Had to do some research before deciding pwn fans are what I want...

Not yet, these Phanteks are still out of stock everywhere, I cannot find them!

What is the easiest way to achieve this? Even if you could, under motherboard control, keep the fans turned off under idle or low system stress conditions the adaptive nature of the Haswell processor would cause issues without active CPU cooling. For example Asus have at least one motherboard where...

I have the Asrock Z97 Extreme 6 and using Phanteks XP PWM 140mm fans. What I would like to do, depending on what I am doing is: 1. Have fans off 2. Have fans run at 600rpm; and 3. Have fans on full What is the easiest way to achieve this? To confirm, I have 4 case fans in my system only. My PSU and ...

Looks like PWM wont work very well on my board as I only have 3 headers and have 4 fans.

So I am now thinking I'd like a hardware fan controller. Lamptron look good but they need loads of power as they are aimed at the gamer market. Can anyone recommend a controller?

Thanks all. My preference is for internal since I've found external annoying for a while now and part my justification for a larger case this time around is to fit everything neatly in it (it being the powerful computer as opposed to the HTPC etc), so that power settings option looks good. What abou...

Thanks guys, this is very helpful

I want to use a moving disk for backup and ssd for everyday stuff. Is there a way to turn off a HD with software? If not, what is the hardware solution?

Can anyone tell me if this programme allows that the fans are completely off until a certain temperature is reached?

I'm building a passive (but powerful, i7 4770S) system, but would like the ability for the fans to come on during, say, video rendering or playing games.

Thanks
