Question x3 molex fan connectors daisy-chained. Looking for a fan speed control solution.

[tomachas]

Hi,

I have an Aerocool Hexform case with x3 preinstalled fans. They are daisy-chained Molex connectors. What is the cheapest solution for fan control?
Convert? If so, would one converter to 4=pin do a job? My motherboard is ASUS PRIME B650M-A WIIFI II. Ideally, I would settle for a few pounds solution if not, I would buy a set of new 120mm fans for around £15 and I am done.

Many thanks!

I looked up the cases and it's price. It's a 17USD case, so the fans are bound to be powered only by molex which are pretty much bottom of the barrel. This is a good read;

[SOLVED] - How to control Molex fans speed?

My 3 Molex chassis fans are "daisy chained" and connected directly to the PSU, making them run at 12v, full speed and very loud all the time... my Asus Prime B450M-A has a CHA_FAN2 empty connector right over the CPU_FAN connector, if i get a Molex to 3-pin cable can i connect them all on the...

You'd be best off with a cheap DC or PWM fan pack akin to this;

You can get a rheostat controller for Molex fans, but some of them don't respond as you might expect with the reduced voltage.

I would also suggest looking into new fans. Something PWM/PST or a fan hub alongside.
