Is using an external fan needed with a Mac Plus?

[trag]

trag, LOL, I LOVE that! I had seen that picture on the net before ... now I know it was you! It's like some kind of Wizard of Oz Mac.

I gave some nice fellow permission to use the pictures in an article on heat disposal that he wrote for (IIRC) IBM's website. You may have seen them there. Unfortunately, I can't remember who the fellow was. I don't really need to know. It's just kind of disheartening to have a friendly exchange with someone and then a few years later you have no idea who it was....

David, it would be VERY helpful if you could open your Plus, remove the analog board and shoot some photos for us. Seeing the numbers on the analog board is what we're mainly after, although I wouldn't mind seeing the flyback and other components used on your board.
You can see my analog board photos here.

I really need to get back to this. I have been busy with other things. I will take it apart and shoot those pictures as soon as I can.

It's worth a try ... however, it does not sound as efficient. The entire configuration was designed to maximize convection, i.e. the hottest components located near the top to draw cool air up. Forcing air down through the Mac would actually send hot air down into the case.

I added a fan to my iMac 350MHz and it was blowing on the logic board(the other side where the HD and disk drive are located) and it worked just fine. I added an ATX drive cable expander to the existing ATX cable inside and it worked just fine. Not sure if the older macs have the regular ATX connections but its worth a try.

Macintosh Repair and Upgrade Secrets is a MUST have for the Vintage Mac user and fairly easy to come by these days.

Has anyone read this book?

Chilton's Guide to Macintosh Repair & Maintenance (1986, 212 pages)

No one has a copy of the Chilton's Guide?

I am interested in knowing how it compares to what Larry Pina wrote. If I were back in the states, I would check it out at my local library in a heartbeat, but I can't do that from Japan.

So if any of you know of this book, do tell!

Thanks.

Isn't Chilton the guide typically associated with automobile repair? I remember using one at the library many years ago to diagnose a problem with our family's 1985 Honda Accord so we could explain it to a mechanic who was looking at buying the car (which we opted to replace instead of repair due to its age).

Back in early 1984, I haven't the faintest idea if they also covered automobiles. But here is an actual auction for the "Macintosh" book I am talking about:

I have a Kensington System Saver Mac and the fan is pretty quiet. Most times I wouldn't notice it running. When I first got the unit I had a bit of bearing noise at first but after lubing it that quietened down. I don't know if it has the original fan or not. If yours is unpleasantly noisy then I'd probably shop for a replacement fan.
