Default The cheapest fan controllers (for stir plates)

Can anyone beat this? Free shipping too.

Single controller - $2.49 - DealExtreme: $2.49 12W Variable Speed Controller for PC Cooling Fans

Triple controller - $6.65 - DealExtreme: $6.65 3-Fan Cooling Fan Variable Speed Controller for PC


I have not ordered these items, but I have ordered from this site before. It is a trustworthy site, but it can take a couple weeks for shipping because everything is straight from Hong Kong.


Also, of note, they have very cheap rare earth magnets.

heres a link from newegg.com for your first controller, a little more expensive, but it comes from the states and you'll probably get it sooner.

Newegg.com - ZALMAN FAN MATE 2 Fan Controller - Controller Panels

That's $10, after shipping, though. I think I'll just wait the extra week and get 4 of them for the same price....

Just pick up a small potentiometer at Radio Shack for $5 and use a 9 - 12 volt DC wall adapter.

Those controllers are just potentiometers anyway, and cheap ones at that. I would definitely just get one from rat shack for the same price, it will be more beefy anyway.

The RS here in my hometown no longer carry the 3watt 25 ohm rheostat in-store, from what the fat, slovenly, lazy bastard at the counter told me they must be ordered on-line. I had him check all of the other locations here in town, and none of them are carrying them. I dunno how reliable Jabba's information was, but I ended up ordering mine on-line, along with some other stuff, any order over $10 has free shipping.

Just so you know, his twin is in Louisville. I think that they only sell Cell Phones anymore. I've been in there when the Manager has given people just flat wrong information.

Anyone who wants a kit could deal with Welcome to Stir Plates.com - guy seems alright and his work looks good.

fwiw dealextreme is extremely slow to ship items, their prices are cheap but if you are in a hurry its worth it to pay an extra few dollars imho

That looks like a pot that can handle a fans mA load in a plastic box, nothing special by the looks and price of it.
There is a limit on going to cheap as it can bite you in the butt with problems I rather not add to my brew day.

Google; ECROS Technology. This will take a couple days for shipping. Their 1.5 amp output LM317 based adjustable voltage regulator in a complete parts kit. Solder it together, install in a plastic Radio Shack project box and be done.
The higher amp regulator with the larger heat sink goes for $9.95. This regulator plus shipping to the S.F. bay area cost me $15.45. I went wild with my spending on this project. Cheaper kits with only 0.5 amp output for $6.95 vs $9.95. My collection of fans draw 720 mA hence the larger 1.5 amp unit why push the limits and let the smoke out? They have wall-warts 6, 7.5 and 12 volt for $2.95 to $4.95. These power cubes grow everywhere everyone has bunch of them around the house. My stir plate will cost me a voltage regulator and a project box. Curb side 12 volt fans of 720 mA, six free. I can afford to waste some big money on a regulated power supply rated to 20 watts output i'm not wanting to fight stir magnets being tossed inside the flask going cheap with a basic pot speed controller as this fan will smoke the small Radio Shack pots. Already have a 250ml flask in the shop and a friend is giving me a 2,000ml and a 4 or 5,000ml flask also free. All he wants is some homebrew a fair trade in my book.
