Computer fan speed controller. any wants?

banditpowdercoat · #1 02-08-2010, 02:40 PM

I am placing an electronics order to make some 12v computer fan variable temp/speed controllers. I am wondering if there would be interest? As it sits, you would have to supply a power supply and the fans. The controller will be housed in a plastic box with tangs to be able to screw to the inside of stands, or canopy's, with a temperature adjust dial. Instead of just a ON/OFF style controller, this will vary the fan speed. As temp increases, so will fan speed. Should be able to control up to 25W+/- 5w worth of fan's.

Wondering if there is much interest? Price would be $25-35 range

I got enough supplies for 10 controllers on order

No one want's quieter, automatic cooling fan's?

Other than the fan & power supply, and of course your controller, is there anything else needed to make a setup?

Would the controller work for multiple fans, or just one (assuming they are using the same on/off/speed as the controller is set at)?

I have a heat problem in my tank cover and this might be what I was looking for.

If it becomes popular, I will probibaly have complete setups with fan, controler and power supply, like Icecaps 4" fan, only with adjustable temp, and with a better price.

For now, the controller will have terminals on it that you can connect a 12v supply of your choice, and up to 25-30W of fan's Alot of 4" fans are 6-10W. So, depending on fan's used, will depend on the number can be used per controller. I am looking into higher wattage capabilities, but I need to see if there is going to be a market. But also, for the price I will be offering these for, it will be well within the reach of most all enthusiasts to even mount 2 in a canopy. Appears price will be in the low end of my estimate scale.

Any more questions, or idea's, fire away!

Dan:
What is the temp range that this can be adjusted to/from?
Thanks

I havn't checked the full range yet, but I will and post temps. It will have a fairly large temp range. Should be able to cover all temps required

Also, the range of temps will vary slightly depending on load of fans attached to the controller.

I like the idea of temp flexibility.
I'll need to work out how to jimmy a fan or three in my tank cover, its kinda cramped. If you can put together the controller for $ what you figure, I'll take one.
Let me know when you've got a working set up.

OK, Update, I have the prototype working on 2 fans in my sump cabinet. Working great. Warm sensor up, fan speeds up, cool it down, fan slows down. My sump pretty much remains constant temp. These would be more benificial in automating Canopy fan's and as I do not yet have a canopy Adjust the Rheostat for the temperature. Takes a little fiddling to get temp setting right because Rheostat is not a set temp for a certain position. It's dependent on the load connected. Change any of the fan's, Add or remove some and the setting will require changing.

Heres a pic of what it will look like. 2 screws on the right for the incoming 12Vdc power supply, and the other 2 for the fan's

First batch of 10 will be at a Introductory Price of $15 ea + shipping

All parts used are RoHS compliant

Cool, Dan - You didn't say it would come with a Laptop!
