Thermometer Locations

[supanatral]

I have iStat installed on my mac book pro and it has the tempature readings on it but I don't know what half of them are. There's a thermometer in the following locations:

CPU A
GPU
GPU Heatsink
Heatsink A
Heatsink B
Enclosure Bottom

Could anyone let me know what these are actually reading?

I'm not totally sure about this, but.
The CPU A is measuring the full Intel Processor (both cores).
The GPU is measuring the the Graphics Processor itself.
The GPU heat sink is measuring the heat sink for the Graphics Processor.
Heat sink A is measuring the heat sink were the fans blow the air through one side of the screens.
Heat sink B is the same at A but on the other side of the screen.
Enclosure bottom is measuring as far as you can go to the bottom (under the motherboard) the piece of metal that sits on our lap.
