i was wondering if the athlon 2's are known for a messed up temp sensor? mine will tell me it's running at like 16 celcius. thanks

I have a Regor 240 and I don't think it's a faulty sensor. Although it says around 19 centigrade at idle and like 40-50 at load (BfBC2). Stock fan and heatsink etc..

So it's possible for it to idle that low? From what it says it's idling at or below room temp....

What can I say? It could be faulty sensor but it's not being used much and it's below room temperature?
Remember that it has a 2500rpm fan and heat-transfer grease too!

It can not idle below room temps. just not going to happen. Well with phase change it can :) 

Many CPU sensors are very inaccurate at idle since they are deigned more then anything to be the trigger point for over heat protection.

I would not worry about it, My i5 idles @ 14c in a 20 c room according to my board sensors(600rmp fan), but the Intel sensors say in the mid 20's.

Your board also has a sensor you can check with something like HWmon. On my gigabyte board, my AMD X4 BE 955 temps are within 2 degrees from cpu sensor to board sensor. very well calibrated

OK so with HWmonitor, there's TMPIN0, and TMPIN2. What do those mean?

temp sensor can be off 4-5 degrees , most likely if it is below room temp at idle

Those are board sensors. Most times there is a Case sensor and a CPU socket temp.

Easy way to see what is the cpu socket temp is to just run HWmon then fire up prime95. The cpu temp rise fast and the other will not rise so fast.

Some boards also have a sensor near the chipset those temps raise as well, but not as fast.

In some cases you can even have a sensor that is not connected to anything show up(the chips used have multiple inputs and not all board makers use them all). Those will show strange temperatures like 88, 128, 256, ect all the time. Those can be ignored if you have them.

Any time.....
Did you hackintosh an AMD system(your avatar)?

Speaking of that, where did my signature go(yes, your avatar reminded me)....hmm better get that re fixed.

EDIT, ahh better :)
