Is there such a thing.....

[Phrik]

.....of a fan controller that uses PWM information to automatically re-adjust fan speed of other non-PWM (3-pin) fans ?

So basically, a 4-pin PWM fan header from motherboard goes to this fan controller, let's say receives instruction to run fan at 50%, the controller then translates this as giving the usual non-PWM or 3-pin fans only 50% voltage to run with.

Such a thing exists ?

I got loads of different 3-pin fans, and I don't want to waste money on buying new PWM fans, and I don't want to buy another fan controller that still requires manual adjustment. I'd much prefer it hidden, automated, and no software to handle with.

Cheers

PWM fan hub. I have one in my phanteks case. It connects to a sata power connector and uses 1 4pin to 4pin cable to connect to either the CPU fan header or the primary 4pin chassis fan header. I believe is uses voltage regulation to adjust the speed of the other fans in the system. I have some 6 or so fans connected as of right now. As for a controller I'm not so sure.

Not specifically a controller, it was the only word I could think of But I'll check in phanteks website...

Ooooh does sounds like it.... thanks !

Hmmmm couldn't find a reseller in NL >.>

Anyone else has a suggestion for a different product/brand, or maybe reseller within EU ?

Is anyone using that Phateks pwm hub? I've read that it only winds up delivering variable voltage between 10.x to 12v, which doesn't sound helpful at all.

For anyone that has it, do your 3-pin fans spin down low enough (350-600 rpm)?

The Rheosmart is what I usually recommend, unfortunately, it seems to be discontinued.

As for low speed fan control, it really depends on your fan. A 1000 RPM fan can get down to the 500 RPM range, while a 2000 RPM fan will struggle to spin at 700 RPM. Most fans require a minimum of ~5 V (~40%) to keep spinning, thus their minimum RPM would be 40% of their maximum RPM. The voltage and RPM of the fan is linearly related. 10v is ~83%, so only a fan with a maximum RPM of 750 can run at 600 RPM at 10v.

The NZXT Grid+ might be a good alternative. It's not PWM controlled, but it is USB controlled.

Mine do. The F140SP spin down to about 500rom no problems. I haven't checked the voltage.

In other builds with PWM fans I get rpm ranges of 300-1300rpm, 500-1300rpm andd 550-2500rpm with Thermalright TY-14x series fans.

Bleeeh, after a few weeks of finding a good deal in EU, I end up buying from the Amazon US to be shipped to EU. 20 USD and 7 USD for freight, is far more cheaper than 20-30 EUR and 10+ EUR shipping within EU...

...But I hope this works !

It works perfectly, the PWM signal from the motherboard automatically adjusts my 3-pin fans. This saves me buying 4 new PWM fans when my current 3-pin fans work amazing and are quiet if controlled properly.

Thanks everyone !

Thanks for letting us know it works. Always good the know when a plan comes together.
