CHUD Nap Reset Question

in Current Mac Hardware edited January 2014
Saw an article about setting the Nap preference on for Dual G4 to let them run cooler (and less fan activity) by checking the box in Hardware system pref.

Now I find it unchecked after a restart. Anyone know how to make this survive rebooting?

    I've read that toggling this option for extended periods can be very BAD to your system.

    There's probably good reason why Apple hides this option from the average user.

    It does make the Dual G4 run cooler. But it has also resulted in 2 hard system freezes in about 5 hours. I think you are right. Back to the high temps and noisy fans. Thanks.

    I don't see any differences between enabling the Nap and disabling it.

    PowerPC G4 7455 v3.2 here DP 1.25 FW800. Anyway, I replaced the stock old Delta fan to Panasonic Panaflo L1A tho.

    There is a report/discussion about it here:

    About half the people reporting said they had hard freezes. The other half said no problems.
