Insanely low temps, are these even possible?

Hi all
Recently upgraded from the stock AMD heatsink (the one without heatpipes) - and I am running a Propus (AMD Athlon x4 640 at 3ghz)

I currently have it undervolted from 1.4v down to 1.3v - and I upgraded from the AMD heatsink to this Cooler Master Hyper 212 Evo.

Here is my idle temperature. What the hell.

Is that low of a temperature even possible?

Here's what's scarier. After around 3 minutes of priming (something that would previous send my old heatsink skyrocketing into the late 50's early 60's, this one does it at 17 degrees centigrade.

Are these temps even possible or is something seriously wrong here? I am using the included grey thermal paste that comes with the cooler, my AS5 hasn't arrived yet!
 
Well, is your room below 5 degrees centigrade? If a cup of water on your desk is freezing, then the temperature might be right. If your room is at a more usual 20 degrees or so, then "Piriform Speccy" is clearly wrong.
 
My rooms ambient temperature isn't 5 degrees, but the air around the intake could possibly be, it is cold outside!
 
Running completely fanless, No fans on other than the GPU fan and the PSU fan along with my windows closed!
Priming for about 15 minutes, results in a temp of 48 degrees centigrade as reported by core temp! This is fantastic!
 
It's reading the wrong sensor or reading it incorrectly, common on amd chips. Use hwmonitor and your real temp will be one of the tmpin values under system.
 
Okay, which of these temps should I trust?

If Speccy along with Core temp are both reading the wrong temperature, it begs the question, what temperature are they reading?

AMD are notoriously bad for incorrect readings on the core temps. My AMD under-reads by about 20°c.

My chip is a Phenom II X4 B60. (Propus)

Download the trial version of Aida64. I did and it identified my CPU temp as "TMPIN2" as shown in Open Hardware Monitor.

As pgi947 says, CPUTIN seems more likely to be your actual CPU temp.
 
Okay fair enough but what the hell is Core #0,1,2,3 then if not the CPU temp?

I'll be glad to upgrade to the 3570k just for accurate temperatures!

They're the core temps, it's just that they massively under-read.

I use Open Hardware Monitor and it allows you to set an offset for the temp readings. I've just added the difference between my CPU and cores so that the core temp reading is roughly the same. (I've set my offset to +19)

That makes sense I guess, seems like a really dumb thing to do honestly. Either way, I applied an offset that makes the core temps roughly equal to the correct reading in Hardware monitor - and highest it goes while priming is 43 degrees centigrade, which I still think is pretty good!

Thanks everyone!

There's clearly something wrong here, those temps are absolutely NOT! correct. I can say this with extreme confidence because of the temps shown for your SSD, compare them to mine:

Every SSD in the world registers incorrectly with HWMonitor, it's a bug which has yet to be fixed, as you can see the reading of my SSD shows 128c, and I guarantee it's not! :p
