Core i5 idle temps.
can anyone tell me their core i5 idle temps? I have seen a few reports of some i5's having more then enough thermal paste and that re applying drops the temps nicely, and probably slows the fans a bit saving a tad of battery.

Right now i have:
CPU: 31
Base 1-3: 24
GPU: 28 (I'm using intel)
heatsink B: 27 <--- not sure what this is

You are fine, that is an excellent idle temperature.
The heatsink is what presses against the CPU chip and carries heat away from it to the fan. If your paste was "bad" you would see a big temperature difference between the CPU and the heatsink. The fact that you only see 4 C means that your paste is pretty "good". 31 C is nothing - your CPU is rated by Intel up to 105 C. If you work your CPU very hard (eg gaming, ripping DVDs) you might see temperatures close to this maximum.

Re fans they normally idle at 2000 rpm, that's how Apple sets them. When your computer is working hard they will eventually rise to 3000-4000 rpm. Max IIRC is 6200 rpm.

So I wouldn't worry about paste, in your case I am pretty sure it would make no difference whatsoever to your temperatures.

Enjoy your Mac!

Heatsink B is NOT the CPU heatsink. Is it maybe Northbridge?
