Macintosh II Family: Fan Regulator Voids Warranty



I have heard of a small device that can be installed inside the Macintosh
II power supply, with a remote temperature sensor mounted near the hard
drive. The function of this device is to regulate fan speed based on
internal temperature so that fan noise would be greatly decreased.

Does installation of such a device void Apple's warranty?

Installing such a device definitely voids the warranty.

We strongly discourage installing such a device because of, among other
reasons, the differences in temperature within the housing versus where
the device's temperature pickup is located. This would be compounded by
the quantity and locations of NuBus cards, RAM, and whether there is a
hard disk drive or multiple floppy drives installed.
