MacBook Pro 13 - iStat claims 0 temperature for Heatsink A

[omgitscro]

Ever since buying my MacBook Pro 13, 2.26GHz, Heatsink A has been reading a constant 0˚C in iStat menus. Is this universal, or will I need a replacement? I have only modified the amount of RAM so far, I bought 4GB of RAM from Crucial on Newegg, and I have been using Macs for close to 5 years now. Thanks!

EDIT: I just installed the iStat Pro widget, and it doesn't even list Heatsink A as a temperature sensor. I'm going to assume that iStat menus is incorrect in listing it as an option, and that it doesn't exist on any MBP 13.

this is what istat pro shows in my mbp 13''.

Does the 13" MBP have two heatsinks?

My macbook has a pretty busted fan system, and it used to say that my Heatsink A (which is near the CPU i think) was up in the 120+!

Then one day it dropped to 0, then disappeared..

Maybe a faulty temperature sensor....?

Bad fan in my airbook caused the same reading.

could be....


do you live in the arctic?

Technically 0 degrees Celsius still has heat. : )

Kelvin is the only real measurement of heat. Since 0 on the kelvin scale represents "Absolute Zero" or zero vibration of molecules.

I am pretty sure the MBP 13 only has 1 fan so 1 heatsink.

It would be impossible for a sensor to ever "measure" 0K because the sensor would have had to have been AT 0K to begin with, or else it would release heat into its 0K environment. ;P

Thanks for the replies, everyone. I'm pretty sure it's just weird naming on Apple's part, and there is no such thing as a "Heatsink A."

Mine only shows B so maybe it says 0 for A as there isn't one
