Gun oil is a good thing

Dad's friend sent a small bottle of gun oil. When my Toshiba r100 fan strikes again, the system prompts:
The cooling fan is invalid. And the noise is relatively high. I wanted to change an original one and asked about the repair point: the original one costs 300 yuan. Also
Let's take care of yourself, remove the fan, clean it to dust, split the heat sink and the fan, and tear the wind
The label behind the fan is loaded with 2 drops of gun oil.

Test: WriteProgramTo perform Mac operations in an endless loop. The purpose is to occupy CPU resources and enable the fan as soon as possible.
When the fan is turned on later, the noise is a little high at first, and the sound will not be heard slowly (the original sound of the r100 fan is very good.
Small ). Continue to run for 2 minutes. Kill the test program.
OK!

After six months of use, there was no prompt of "cooling fan failure", and the noise was almost invisible.

Cause analysis:
1. Toshiba's r100 fan adopts a Turbine Speed Control fan. The CPU can control the fan speed to save power.
Yes. When the fan speed is lower than the expected system speed, the system will prompt: "cooling fan failure ". And cause wind
The reason for the decrease in fan speed is nothing more than wear and dust.
2. The gun oil is indeed a good thing. I have used Vaseline, oil and other lubricants before. But these lubricants are quite attractive.
It is volatile and remains faulty after a period of use. However, since the use of gun oil, more than half a year of fan performance still makes
Satisfied.

Conclusion: military products are indeed extraordinary.
