Upgraded Banggood mini Tesla Coil with Fan

In this short video I show you a change that I made to my Tesla Coil.. I realized that the heats were very hot and so I decided to add a fan, since the PCB was designed to host one.. not having found a fan so small at 24V, I solved the problem by adding a voltage regulator LM7812.. in this way the coil can be safely powered at 24V.

I know that this is kinda dated now, and I’m really surprised to see that I’m the first “like” after all this time because a quick search doesn’t yield any similar fan-based upgrades! Ironically, I made the very same upgrade as the board was very accommodating for it! 👍 Now, the 12v fans that I had in my “box o’ parts” were a bit larger, which is a shame as I had maybe a dozen (or very close to it) 5v fans. So, I tried a couple of things to attach the fan above the heat sinks with the goal of the fan being sturdily attached, rather than having it loose and maybe falling off.
Now, my “solution,” which in retrospect could have been cleaner, DID work well. I ultimately bent the last blades of the aluminum ever so slightly bilaterally to allow two screws to be secured through the fan’s screw holes and utilizing an extra nut to maintain tension around the screw from the slightly bent aluminum. I then used a long zip-tie to go around this setup to further add tension to everything. Next, I attached two temperature sensors via two different multimeters (a Fluke 17B+ and a Brymen BM786) to each the heat sink and fan. I fired the coil up at 16.5v for 30-minutes and was frankly amazed that neither temperature went above 80°F - Yes! Fahrenheit! - And, yes! Operating for a sustained 30-minutes! It was actually leaning more towards 70°F the majority of the test! 😮 The solution certainly felt sturdy enough, it did the job, and surprisingly did it all quite well! It just wasn’t the prettiest solution, albeit it doesn’t look “bad” either. The bends and slightly scraped paint was just not very aesthetically pleasing, not to mention the zip-tie. So…
How did you secure your fan to the unit? It looks very clean! I would guess hot glue, but for whatever reason hot glue was not being my friend during this particular project as I had to reapply it more than once. I also thought that the instructions should have said to glue down the coil earlier to allow for better distribution of hot glue all the way around the base of the coil. Either way, it’s working and a large fan is keeping it all very cool. I now think that using a large fan may even be beneficial as it would require a bit more power to run, thereby reducing the energy being wasted as heat, because it’s simply being utilized as electrical energy! 😃
Please reply with what worked for you and if you had any similar experiences to share during your installation as we used almost identical parts. I guess that’s “by design,” but still. Anyways, much thanks! ✌️

Hi, sorry for the long wait! I glued this small fan with a glue that in Italy where you live is called "Super Attack" - not the best solution but very effective and without bending the heatsink fins... Thank you very much! =)
