| Active/Passive CPU cooling |
|
Definition
heatsink/grease/fan
Active slows down the processor after speeding up the fan
Passive slows down the processor before speeding up the fan
In short: when active the fan speed on your laptop will constantly work and cool your laptop. on passive it doesn't work unless the temp is too high and it's forced to cool down the PC. Exept a bit more noise, I think active is the best choice. |

update BIOS, or update software burned on ROM chip
Firmware refers to read-only memory (ROM) chips that store permanent instructions. Firmware boots up computerized or digital devices, as ROM chips are non-volatile, meaning they do not require a power source to hold their contents.
Firmware update is a software program that can be used to flash update the firmware in those devices. For example, a user could download a firmware update for their disc drive or network router to update it's capabilities or fix an issue with that device. Firmware updates are made available through the hardware manufacturer |
