we use the word "adjustable" as a replacement for PWM

good link for the review! smile.gif

If you want PWM adjustability, Sunbeam makes an option that'll make any 3 pin fan speed adjust via Motherboard PWM signal. It'll also allow a good 30W per channel. I ordered one from egg the other day, so I could include it as an option to consider for pump noise control also.

They also have a larger model with even more channels, but I don't need that much power.

I haven't started any testing on mine yet, but I'm happy with my old sunbeam controller, it's been running strong for several years now and still kicking.

What is the difference between PWM adjustable and adjustable?(by a fan controller)

Thanks, Sir Overkill.

PWM = adjustable through your board's BIOS or software, these fans have 4 wires and 4 pins that connect directly to your motherboard

Other fans need to be connected to a fan controller so you can adjust their speed

Any ideas how to controll these excalibur's then?
They are pretty loud and I haven't got my fan controller yet. Where in bios? or what software? any ideas anyone?

Thanks, Sir Overkill.

Just plug those excaliburs to your motherboard's fan sockets.
Then go to your bios and look for the setting which says something like "fan control" Or "smartfan" i dont know exactly as i havent used your brand of motherboard.

Yeah, PWM is just something you can tie to be thermally throttled depending on CPU temperature is all.

A basic fan controller is by far a more simple and easy to use method. I also found from a splitting hairs noise perspective that voltage control is ever so slightly better.

As far as the Excaliburs vs GT in CFM/Noise ratio...the GTs were far superior. A good 10dbA on the radiator.

So does that mean the excalibur can't do over 30cfm? Also what about static pressure? which fan is best?

Thanks, Sir Overkill.

That test shows the fans pushing through a radiator, which requires static pressure. Thus, the static pressure of the fans is being shown on these graphs already through their CFM/DBa ratios.

Just get the GentleTyphoons.
