Default Stir plate fan speed controller???

I have a 12v power supply, my fan is 12v and I got a 10ohm potentiometer. I am doubting my choice in 10 ohm... Is that high enough or should I get a rheostat that goes up to 100 ohm? I wanna do this the cheapest most efficient way possible... Suggestions from the experienced people would be appreciated

Consider a 12v led dimmer module. These can be found on eBay for buttons (~$2-$3) and use PWM - very effective for motor speed control.

EDIT: Link -

Realised this afterwards and edited my post - moments too late it would seem !

It's all good, how would I fit this in a project box? I may need to get a larger box possible if it goes in straight up

There is just a single board inside these with some wires to the knob on the front - the box they come in exaggerates the size of them greatly. See the thread below for shots of the internals: but pay no attention to the modifications they are making - they do not apply in this circumstance. Since the knob is connected via wires this should give you flexibility in how to squeeze it into another box.

Fantastic sir! So just cut the board off or just run the board in the box? I'm new to this type of electrical work. I'm very able to do most other stuff... Sorry for all the noob questions

I disassembled mine and took some photos for you.

This is the complete unit. The knob literally pulls off and there is a nut underneath to undo that holds the workings underneath in place. There are also 4 screws on the face of the device to remove.


This reveals the internals - and the knob should now also be free of the front cover of the device. Now the external green wire terminal just pull out again - literally just pull out and the board itself is held by two screws that need removed.



What you are left with is the actual parts you need that are at the bottom of this image and a knob as well. Everything else has little purpose. To mount the knob, all you have to do is drill a hole in your box to accept the it and use the nut taken off earlier to secure it in place.
