Hi there,
Just built a new system and installed some RGB fans. The fans all connect to a hub which is powered by a molex cable. Just wondering if there is any way that I can reduce the fan speed? Maybe an adapter that would connect them to the motherboard?
Thanks

Not all the Fans' 6 pin connectors are the same, even if you find just the fan controller by itself, you'll need to ensure it's compatible with your fans 6 pin connectors: Help with RGB fans.

There's only a molex cable. But there is another slot in the hub that says DC above it

There are multiple fan splitters or Hubs with sensor extension that runs to the motherboard fan header and would allow you to control all fans connected to it speed. (but not individually)
There are also some molex to 4x3pin or 4x4 pin fan or more splitters down volted to 5V or 7 V or mixed voltages, I just bought one the 5V splitter to run quieter 3x60 mm top fans and a blower PSU helper fan for Small Form Factor custom system = whisper quiet result and no need for a resistor based solution.
take a look at this : 4-Pin Molex to 4 x 3-Pin Fan Connector Cable (Power 4 Fans from 1 Molex with motherboard Fan sensor feedback) >> https://www.ebay.com/itm/ModTek-4-Pin-Molex-to-4-x-3-Pin-Fan-Connector-Cable-Power-4-Fans-from-1-Mole/302716770931?epid=1030637020&hash=item467b535a73:g:VLgAAOSwsaZa4Ezs

The hub came with the fans, not the case

get some NZXT or other brand FAN HUB with slider manually adjustable speed (sata or molex powered), or a fan hub with motherboard sensor you connect to one of the motherboard fan headers allowing you to control all the fans hooked to the header speed wise through your motherboard software (all the fans will run at the same proportional speed)

I've looked for different fan hubs but can't find any with my fans connection. They have thin 6 pin headers

Yes I know they're RGB and I've been looking for a controller for them but can't find one that would fit the fans headers

They're only cheap ones, I'm a student and couldn't spend much on them.

Is there anywhere I can buy just the controller? Because this comes with fans as well
