Prolonging the Mac's life

Post by retrogamac » Fri Feb 01, 2019 7:07 pm

Temperature-controlled cooling is a real killer for old hardware.
People do not notice when the fan dies.
When they notice the fried electronics it is too late.

For this reason and for generally prolonging the life of the hardware I prefer fans run at full speed.

I have made photos from my work inside the cramped power supply.
But I am not sure whether it is desirable to post photos.
The work with high voltages is not recommended for unskilled people, which should not be encouraged to do such things.
If you are skilled, you won't need instructions how to connect the fan to 12V anyway.

I did that and noticed that the fan is quite weak for my taste.
It is better than before, when it an airflow was noticeable only barely.

what do you mean by (fried electronics) ..?
I do not understand.

for the cooling me I multiply the fan and I connect them in 5v or place of the 12v as these possible. for decreased noise.
there is also the laptop fan with the heatsink aluminum and copper, but we must choose the model that will go well with the macintosh

What I mean is this typical situation:
PC with temperature controlled fan. Fan getting old or defective. Turns slower and slower, finally stopping.
User does notice nothing. Only thinks "that is a nice quiet computer!"
PC without cooling runs until overheated electronics finally break down.

Especially early 2000's hardware was getting really hot, when they cranked up the CPU frequency super high... right before they begin selling dual cores. Those were the only years that I saw with my own eyes some laptops (not mine!) heat sink plastic MELTING. I never saw that before and today we do not see that anymore, because laptop CPU's now have many cores and generally speaking, lower frequency. It was common back in 2002-2006 to see CPU's as hot as 70'c which is considered impossible nowadays since the motherboards will automatically shut down when reaching 55'c.
