Mac Plus fan installation


Active member

My Mac Plus works well (recapped etc...) but come very hot after some time of use (I have 4 mb ram and also a bluescsi powered by the Mac).

I like the MacChimney, if anybody has a developed drawing i will give a try just for see !

I have buy 12 Vdc 40x40 and 50x50 mm fans for install in the top right rear small clipped panel (will use of course the one which fit best at this place).

If someone has installation picture and a way to fix them without modifying the case (holes drilling etc are not options !) ?
Also where can I take de 12 Vdc power (~ 0.5 W) and be sure not to overload the power supply ?

Thanks, regards.

Macintosh Repair & Upgrade Secrets has a section on installing a fan non-destructively. I would start there.
