possible mistake in reapplication of thermal paste

i reapplied some thermal paste to my macbook and i think i did it somewhat successfully (writing this on my MB right now). i did this because the temperatures for my cpu core's were consistently above 80 and got up to 90-100+ when doing very computationally intensive tasks.

now that i have it booted back up, when i launch 'Temperature Monitor' it says that cpu core 1and cpu core 2 are 'disconnected'. i am assuming something happened and i may have somehow disconnected the temperature diodes or soemthing. is this fixable? what should i look for when trying to see if it is a hardware thing?

note that i CAN see 'CPU A' in temperature monitor and it reads ~47 degrees. more than anything, i just don't want my computer to overheat due to a lack of knowledge that the cpu is hot and the fan not kicking on.

is it enough that "CPU A" is being read for the fans to turn on?

UPDATE: a simple restart let me start seeing the core temps. i will not delete this question, however, since others may possibly be searching for the same thing and come upon this post. for what it is worth, my computer idled at ~75C and got up to 85-90C when i was playing diablo 3. Now it idles at ~45C and doesn't get up above 60C when i play diablo 3!

You may just want to reset the PRAM or make sure that all the temperature sensor cables are properly seated. In some cases all that is needed is a reboot.
