Overview
The PS2 has a thermal sensor IC in proximity to the EE (or EE+GS, depending on the revision).
On consoles with a Dragon MechaCon (SCPH-5XXXX and later), the thermal sensor is connected to the MechaCon and the temperature can be read from software. On earlier consoles, the thermal sensor is connected to the SysCon and the temperature can (currently) not be read from software. GH-001 and GH-003 use a thermostat instead of a temperature sensor.
LM56
Thermostat, 2 digital outputs for 2 configurable temperature thresholds, used in conjunction with NJM062V op-amp Used on GH-001 and GH-003. (What about GH-008?)
LM74
SPI/Microwire temperature sensor, 13 bit, 8-pin SOIC-8 Used on GH-004, GH-005, GH-006, GH-007, GH-010, GH-012, GH-013, GH-014 (What about GH-008?)
LM70
SPI/Microwire temperature sensor, 11 bit, 8-pin VSSOP-8 Used on GH-015, GH-016, GH-017, GH-019, GH-022
LM71
SPI/Microwire temperature sensor, 14 bit, 5-pin SOT-23 Used on GH-023, GH-026, GH-029, GH-035
PS2 hardware in PS3
COK-001 has unpopulated pads for a thermal sensor next to EE+GS. COK-002 doesn't have any temperature monitoring capabilities next to GS.
