I've said I know it, but it wasn't designed with a fan on it, and I said it could be used to cool the motherboard the same way the Beetle does.
Germans know something about how to cool an engine only with air, see that Beetles in the desert in WW2... I heard there you could change two Jeeps for a Beetle...
 
Any proud German there?
 
About the photo, I'll tell you my father had one in white, although it's very very difficult to see one of those, at least here. I haven't seen one in 20 years :), is there any in the Moon?

BTW, the shielding is for RF interference you know, not a cooling device of any kind.


Hmm... wondered why I was picking up radio 1 on my internal hard disk drive... :)

Try moving the Amiga, perhaps you can tune up some Tv program...

It must be difficult to run an Amiga there, with temperatures between 387º Fahrenheit (-233 ºC) by night, and 253º Fahrenheit (123ºC) by day...

@retrofan,

I can see what you're getting at.  If the fan was inside the shielding as well, and you had strategic holes drilled into the shielding, then potentially yes the cooling would be improved I think because the air flow would be more concentrated over all of the components.

If you didn't drill any ventilation holes then no the cooling would not be improved because the hot air would stay inside the shielding.

Painting the shielding black is a good idea though.  I have tried to convince my partner that for maximum efficiency we should paint all our radiators in the house black, but she's having none of it.  Apparently the radiators would no longer be asthetically pleasing to the eye.  So as long as it looks good, right? :lol:

In practice though I'm not sure by how much the heating system efficiency would be improved by painting the radiators black.  I would like to try it, and generally my partner is very patient with my crazy experiments, but she draws the line there I'm afraid!!!

AH

I have a Beetle and I have Amigas, they are unrelated!

Remove the shielding and throw it away, it's useless.

I was thinking that if I don't modify it all putting tape and painting all black, the next time I will open the sheilding at least I will paint it black inside the sheilding...

When you'll have the engine mounted piece by piece by you we can begin to talk. Air cooled refrigeration is related to any Amiga with a fan on it and PC's although you can't see it. Even water cooling is related to PC's... didn't you think where do they taked the idea? YES, they were cars ! This is my Beetle (Big photo, isn't it?... change your screen size:roflmao:)

Obviously, a sealed duct air exchange system like in a Beetle is good for cooling.  The plain shielding in a 1200 is not.  If you converted it into a sealed wind tunnel and pulled cool air through it, sure, that'd work.  However, you're better off just worrying about the chips that get hot and are likely to burn out and heatsink/fan them directly, the temperatures in a computer are nothing like the temperatures in a car's engine.  The vents in the top of your 1200 do allow heat out.

Well, Ok, that's an opinion...:), I've never said I'm against heatsink/internal fans... and the heat out can be conduced by the sealed sheilding with the proper output for it.
 
I'm working hard to convince people... :hammer:. By now I've one on the list. Any other, ple:)se?

Get yourself a nice '040@40mhz and trust it to your draft-tunnel experiment without its own fan and let me know how long it lasts.

Why do you believe I'm taking so much effort to convince someone to try it before :roflmao:?
 
And the fan is the main thing: you can leave as many fans over any components as you want from outside the sheilding, sealing the rest of it and leaving an output for the air.
 
BTW the last time I saw your Amiga it had the accelerator outside the sheilding, have you changed something? I was thinking in things inside it like the Indivision...

A fan will do more good directly cooling a heatsink attached to your hot chip(s) than it will drawing air through a space that really doesn't get all that hot anyway, unless you've got it crammed full of PPC and BVision stuff.  Sure, throw a nice jet-engine server-type cooling fan on the side of your 1200 for a nice noisy gimmick.

Judging by your car, you seem to enjoy attaching unnecessary things. ;)

Some people call things as unnecessary, others have Amigas and Showroom Beetles... but I like rusty Beetles too :lol:
 
Any other to join the list :rtfm:  ?
