Oh gosh, now I understand! When you placed the metal side against the capacitor, it shorted it out!
Yes, there’s space there, and I’m using it because, in that position, the fan will draw cool outside air through the lower-right vent and push it upward toward the hot area. The air will then escape through the upper vents, while also pushing warm air toward the upper-left side and keeping it circulating.
I’m looking for very small fans so I can take advantage of the new battery’s capacity and fit at least two blower fans. Once my battery pack arrives, I’ll give it a try.
Glad it’s still booting! Check whether the fan was damaged. If it wasn’t, there’s a chance the capacitor is still working. Test it with a multimeter to confirm whether it’s damaged—from the photo, it doesn’t look like it is. It’s not that difficult to replace, but it looks like it’s still working and hasn’t blown.
Exactly! I’m looking for tiny fans used in 3D glasses, with very low power consumption. I found the BSB01503HA3-00 (15 × 15 × 4 mm, DC 3 V) and the SENKAYS 2006 blower (20 × 20 × 6 mm, DC 5 V) - I’m using the latter one.
The BSB is 0.5 mm smaller and runs on 3 V. If it works, it should put less strain on the power supply than a 5 V fan, but I need to install the new battery pack and use batteries with a high current rating. Obviously, I’ll need to build a small board to step down the voltage from 5 V to 3 V and connect both fans to it.
Anyway, once I’ve installed everything, I’ll post photos for everyone. My new battery pack arrives next week.
Hi t8923n! I now understand the problem you ran into, and I’ve fixed it. The original rear cover is slightly recessed rather than completely flat, creating a 0.02 mm difference. That’s why you noticed the gap.
Depending on the printing material, tightening the screws closes that gap, which is what happened in my case. However, if the screws aren’t tightened, the gap remains.
I’ve made a new .stl file to correct this, and this time I’ve even included a .step file for those lucky enough to have a CNC machine at home!
Thanks for giving my brain a little workout, and for your help. Problem solved!
Yes, it would! Especially since I use Anycubic instead of Bambu! And that’s why this old guy uses LimeWire!
Seriously, everyone, I made this for you as a contribution to the community. You’re welcome to share the .stl and .step files anywhere, as long as you credit me as their creator. Just as I credited the person behind the original idea, all I ask is that you keep the proper attribution. Even better… improve it, build on it, and share your versions too! Enjoy!
Well I dont have a printables account but I second what Wander_Menezes has said anyone can download those files and put them anywhere as long as they give attribution so anyone could put it on printables, thingiverse or others.
Yes! Looking at the graph, the temperature stays between 38 and 43 °C most of the time, with a few peaks near 54 °C. The fan kicks in at certain points and runs at around 5,000 RPM.
It gives you more control over cooling, especially if you configure when it turns on and how fast it runs. In this graph, it seems to work mostly in an on/off mode. You’ve gained control, predictability, saving energy, gain thermal balance and gain thermal recovery… simply because you’re circulating the air.
Enjoy!
，在你的提示下，我安装到了原本放4g模块的地方，出风口对着aio扩展板。忘记了拍摄照片，后面优化了补上。谢谢老兄的创意
