CPU temps

I recently got an Zalman Aero flower cooler and an Akasa fan controller. When i turn the fan onto MAX its only goes at 2640Rpm from a lowest speed of 1500Rpm. And wether it is on max rpm or lowest there seems to be no difference in temperature reading on AI Booster. Is using a software program the most efficient way of measuring hardware temperature?. I got some Probes i can stick on various things within the pc but if i put my finger above the heatplate on the zalman it is COLD were the pc says its at 34 degrees C.

i am using Nvidia Ntune to check the temps and i used a program called PRIME 95 to stress test it and it was on for a while and the temp didnt go above 40. i am prob doing something wrong.
