The Muffin Fan! The Muffin Fan!
Pathetic. I don't even know the right way to measure the mm size. Along the straight square edges the fan measures 60 mm square end-to-end all four sides on the Megawatt fan.
The label on the fan claims .19 amperes. Around a two watt draw. Brushless, no info therefore sleeve bearing.
How the hell can a .19 ampere (60) mm fan move any air? This too can be classified as pathetic. I chopped out the entire fan grille on both fans. Trashed.
Now what? Sikorsky grade 60 mm fans for each of the Megawatts? I've got very little room between the stacked Megawatts so a fat fan is not in the works.
Ninerbikes promised to post a raft of my images for an inside look at the Megawatt 400-watt model. There you can see why a fatter fan is improbable. Inductor, caps. transformers, and vertical ceramic resistors hog the vertical room inside.
This leaves me in the market for a "Sky Crane" grade of fan to replace the Chung King original. Brushless, ball bearings, and aggressive blade pitch rather than 10,000 RPM to move a lot of air. Db is worth zero. I could care less if the best fan is an 80 db fan. This is a battery charger not a pipe organ.
But I need help to find the best replacement fan. Everyone is paranoid about noise. I am paranoid about smoke.
It is a testament to the design of the Megawatt that those TO-247 bi-polar transistors can hold up with "virtually no heat sinking". If that Megawatt case is supposed to be an adequate heat sink, I am a penguin.
But that garbage-can fan has got to go! I need to order a pair of really really good fans. I am going to "carry on" with the heat sinking project. I don't even know if I measured those fans correctly.
Four liquid cooled heatsinks? This is a BORG cube, not the GLOMAR EXPLORER. I don't want US Customs pulling automatic weapons and flash bangs on me if I get secondaried.
I have no idea when NinerBikes is going to post that photo album. It might be a good idea to save it to disk.
Next up is a photo essay on how to solder 10-turn pot leads to the two teensy tabs on the original pot. With one hand. Meaning I have some tips and tricks up my sleeve that may make this a simple task for the timid. We'll wait and see. It costs a veritable fortune to text photo messages internationally for both sender and the recipient. And Niner cannot use WhatsApp.
