Ionic Wind PC Cooling

Due to popular request we have built this miniaturized ion cooler as a second step in its evaluation. We chose to use an external design for several reasons, all of which mitigate concerns from people on our initial prototype. One of the biggest concerns was with regards to the air moving through the computer possibly having a imbalanced electrical charge or alternately producing to much ozone and possibly damaging components in the system. By mounting the unit at the rear of the case with it sucking air out of the case we are able to still achieve beneficial results and address these issues. The rig overall is basically the same as in the initial tests with one change that we used a more standard PC case with a normal 2 fan push pull type arrangement.

The Power Source:

We picked up this high power ion generator from for about 30.00. This is a far cry better cost than the disassembly of an ionic air cleaner for the components. This unit is a 12V native unit so we can run it off the internal power supply with out any major issues. This unit puts out several thousands of volts. it can hurt or even kill you. do not do this project unless you have a firm grasp of electronics.

The Project Housing:

So attempting to address other complaints with the original ion cooler we will be taking a more direct scrounges approach to save some money. We chose to use the clear plastic part of a case for cd’s that we had laying around for this project.

120mm Case Fan:

Once again trying to do this project on the cheep we will be using this case fan that we just had layout around. We will be only using the outer frame for mounting the cooler to the case as well as so we have some bling lighting for it.

The Guitar String:

We chose to use an easily available part for the emitter wire in this project. We picked up a replacement high E steel guitar string (.008) for 60 cents at our local music shop.

The Grounding Rod:

For the grounding rod we needed something strong and very straight. We didn’t want to try to straighten out a copper wire and mess with that whole process. So we picked up some copper plated steel wire (14GA) from our local hobby store that worked out really well. Also another alternative would be brazing or gas welding rods.

The Hot Glue Gun:

This is the most important part of this projects assembly. We will be using hot glue for all of our structural support and electrical insulation as well. Its important to use a high temperature hot glue as its more durable as well as stronger bonding to plastics and has a higher electrical insulating property than the low temp alternatives.

Step one in our construction process is to cut the fan out of the fans mounting bracket. This is easily done with some wire snips. If your want to keep the lighting ring functional on the fans bracket make sure to leave some leads to work with. Also save the connection to the Molex connector to the power supply and the wire length for later on in the build.

Next up is to take our cd case and cut the top off of it. This can easily be done with a sharp razor. But use caution in doing this step as plastic can be tricky and slip or crack with out warning.

I am in many respects the text book example of someone who shouldn’t be successful. I was an outcast in my grade school years, and a poor performer in school, unable to fit the standard mold. Fortunately I found small opportunities that I took advantage of, and coupled with hard work they have guided me to where I am today. I spend my time running several businesses I own, developing new products and sharing what I have accomplished with those that deserve opportunities that they wouldn't get any other way. InventGeek has been a step on a path that has helped bring me success and confidence by the simple act of doing. I encourage our readers to do what they can to better themselves a little each day, because overtime it's amazing what you can do!

    I was looking at your project and thinking it might be applied to water cooling.

    I also had a few other ideas about materials that might make it work better and be easier to build.

    I have included a link where I reference your work as well as my ideas if you are interested.
