I have read a rumor that Apple changed the design of the Mac Plus power supply at some point. When users began to install 4MB of RAM in the Plus, the power supply would overheat. Apple examined the issue and installed a better power supply in later Mac Plus units. Mac Plus computers with the second type of power supply were not as likely to overheat.
Is there any truth to this rumor? If there is, when did the change in power supply occur? My Plus has a date of 1988 on it.

It could be Mac128 has had success without active cooling because his Mac Plus was manufactured later in the production run. Perhaps only the earlier Mac Plus computers with the inferior power supplies require active cooling to prevent overheating.
