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 simple thermostat instead of a temperature sensor.

Texas Instruments LM20
Analog output temperature sensor, 5-pin SOT-323/SC-70, SMD-code: T2B. Analog output connected to Dragon-MechaCon, which probably has an internal DAC for this. Some boards that use the LM20 also have alternate solder pads and wiring for a LM71.
Used on GH-051, GH-052, GH-061, GH-062
Seiko S-58LM20A
Analog output temperature sensor, 4-pin SC-82AB, SMD-code: DRE. Analog output connected to Dragon-MechaCon, which probably has an internal DAC for this. Drop-in replacement for Texas Instruments LM20 that can be mounted on the same footprint with 1 pin less (which is NC on Texas Instruments LM20).

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.
