=== Temperature monitor IC's on new motherboards ===
Could be this small squared IC's with 8 pins, one near CELL, and another near RSX

TI0A 411B (near RSX) - http://i.imgur.com/hRk8EBv.jpg (not visible in the photo but it has the "texas instrument" logo)

=== Temperatures commonly seen ===
Note: PS3 manual explicitly states:
 Ambient :: Operating temperature 5°C - 35°C (41°F - 95°F)"

'''notes:'''
* Read out is done with multiman or temperature readout homebrew and notated here in degrees celcius
*The values inside multiman (or other apps not specifics for temperature tests) are meassuring the processing/graphics load of this app. Comparisons between different apps (or versions of the same app) are not accurate
* Depending of the internal design of each model, from a "fresh" start the time needed to stabilish the temperature can vary around 1 hour. Comparisons between not-stable temperatures are not accurate
* When in a stable temperature, there is always a fixed difference between CELL and RSX, for slim series is around +-2ºC (this depends of each model and how close are one of the other, also depends of the temperature of the whole motherboard/console, included metal parts and plastic case)

=== Overheat warning ===
[[:File:Ps3-overheat-msg.jpg|Photo]] of the overheat warning message using "notification window" (at topright corner in main XMB )

'''The text''' is loaded from path: '''dev_flash/vsh/resource/system_plugin.rco/Text/<language>.xml''' (localized for all languages). Example from '''English.xml''' extracted from the .rco with rcomage:
{{Boxcode|code=<syntaxhighlight lang="xml">
<TextLang>
	.
	..
	...
	<Text name="msg_error_console_hot_pls_restart">The system has become hot. Please turn off the system and wait a while before turning it on again.</Text>
</TextLang>
</syntaxhighlight>}}

'''The icon''' (a caution white circle with an admiration mark inside) displayed at left inside the notification window... is loaded from '''dev_flash/vsh/resource/system_plugin.rco/Images/tex_notification_caution.png''' (the conversion to .png is made by rcomage, is not really a .png inside the .rco container... images inside .rco's doesnt uses file extensions)

All the other images inside system_plugin.rco with names starting with '''tex_notification_*''' are icons intended to be displayed inside notification window (13 images in total)

'''The frame''' of the notification window itself (a grey square with a darkest grey border that is scaled accordingly with the text displayed)... is loaded from the same .rco and is named '''tex_notification.png'''... this image can be replaced by using a [[PlayStation 3 Theme (P3T)|Theme]]

Note how the text (msg_error_console_hot_pls_restart) and the icon (tex_notification_caution), are refered by his names in the code below
