Thermal Monitor 2 (TM2) is a throttling control method used on
LGA 775
LGA 775 (land grid array 775), also known as Socket T, is an Intel desktop CPU socket. Unlike PGA CPU sockets, such as its predecessor Socket 478, LGA 775 has no socket holes; instead, it has 775 protruding pins which touch contact points on th ...

Idle generally refers to idleness, a lack of motion or energy.
Idle or ''idling'', may also refer to:

* Idle (engine), engine running without load
** Idle speed
* Idle (CPU), CPU non-utilisation or low-priority mode
** Synchronous ...
