I've been getting around to overclocking my CPU which I've had for almost 2 years. Before I started I wanted to make sure that my temperature readings were accurate. I googled around and eventually ran into this thread http://www.overclock.net/t/1128821/amd-temp-information-and-guide, and it made me concerned that my readings in speedfan weren't accurate.
To see if that thread was correct I downloaded multiple temp monitoring programs and then ran prime 95 for few minutes and then let my computer idle for a few minutes.

As you can see HWMonitor, SpeedFan, and CoreTemp all read the same value for Core Temp both in prime95 and idle, which oddly contradicts the much linked to overclock.net thread because it says that the CoreTemp is innacurate in determining idle temperatures. AMD Overdrive's Core Temp value seems to match the TMPIN2 value in HWMonitor and the Temp3 Value in SpeedFan respectively. This happens in both idle and load conditions.
Turning on and off programs so that only one is open at a time doesn't seem to cause the temperatures to change values wildly. I've seen some people say that having multiple temperature monitoring programs can cause misreadings, but I'm not having this issue.
So the question is, Which core temperature reading is correct: AMD's or the 3 programs I used? After numerous searches, it seems that no one has the real answer.
