Swiftech introduces PWM speed controlled version of the Helix 120x25mm fan

[grouchon]

The Helix 120mm PWM fan features the same great performance characteristics optimized for liquid cooling applications (high static pressure and low noise) as the Helix 120, and it also includes PWM speed control.

The advantage of PWM (Pulse Width Modulation) is well known for its energy efficiency, but the more immediate benefit for everyday use is that you can connect this fan to your motherboard 4-pin CPU_Fan header thus directly linking the fan speed to the CPU temperature. Fan speed is then automatically managed by the motherboard based on your preferred settings (please consult your motherboard user manual for adjustment settings).

Swiftech also offers a PWM splitter cable to connect multiple fans, and thus share the PWM signal from a single 4-pin motherboard connector, which allows all the fans to work in concert depending on CPU speed.

always good to see a fan at the noise operating level of the AP-15.

however, I was thinking.
at 1800 rpm and 55 CFM, doesn't it just makes it a AP-15 replacement?

is it possible to push it further, to keep the same noise ratio, and get better CFM? Just wondering where the limitations are. At the current specs, the COST will be the primary concern about this fan, cheaper than AP-15 will be great.

but if the fan is BETTER than the AP-15 in everyway, then you can charge, 'whatever you want', and people will still be ordering it. hehe.

It has the static pressure of the ap 14 on a radiator.

thanks for the chart..
also proving my point in a way, the PQ curve of the AP-15 is just quite good.
I am eagerly waiting for either corsair or swiftech to do something that will make it obsolete. the first that does.. will dominant the 120mm fan market immediately.

been waitting for some white/ good performance fans to replace my loud/no performance nzxt fans, hope 10 of these wont break my pocket

Nice Gabe. Now a PWM fan header multi PWM output for us. Should have the capability for 12 fans, 4 channels, with adjustments for each channel. Might want 50% on fan bank 1, 60% bank two etc.

Nice looking and capable fans.
