What is it?

Introducing my Fan Speed Regulator PCB – a compact solution designed to seamlessly integrate between your fan and Rambo board, empowering users with the ability to easily adjust fan speed of 5V heatsink cooling fan. It is meant for a MK2/2.5/S but technically it can be used with any printer that has a 5V fan.

Why did you make it?

After upgrading to an MK2.5S kit from Aliexpress, I encountered a Sunon 4010 fan with excellent maglev bearings. While durable, it proved to be noisier than expected, overshadowing the benefits of my previous silent upgrades... Determined to strike a balance between performance and noise, I created this PCB. Now, you can enjoy the advantages of a superior and cost-effective fan while having the flexibility to tailor its noise level to match the whisper-quiet profile of a Noctua fan.
