VERY LOW CPU TEMPERATURE

[John Leonard]

I have an A4-5300 CPU, which is pretty old yeah. I applied new thermal compound and changed its PSU to a new one. However, I left a few mins ago with this PC on while view a live gameplay from Dota 2. I did this just to test whether or not I will still experience unwanted shutdowns. Sadly, when I came back the PC was turned off so I was thinking there's probably still a problem.

 

Upon checking the CPU temperature, I'm REMARKABLY alarmed and awed with the idle temperature that boils down to as low as 8 °C. I attached a screenshot of the desktop with the running game of DotA 2 but why am I getting 22 °C max temp? My ambient temperature sure is not that low. I'm from the Philippines and I don't even have an AC here in my room.

 

CURRENTLY, the motherboard is not inside the case, it's just on top of my table with no other fans on it except the heat-sink fan.

 

Is my CPU dying?

 

@Kierax Sir, it's me again. I hope you can help me.. This is a spare unit of mine, just want to know what really is happening.

Could be your sensors are going wonky, my old motherboard always said it was running at 230 C while cpu was sitting at 28 C.

Yeah, probably. I also tried to tap the heatsink fan and surprisingly, it's not really hot. I'm just wondering why it still surprises me with unwanted shutdown though.

I think that's an inaccurate reading. Notice in HWinfo, your CPU Package temperatures are 52.3–74.9°C, that sounds much more likely.

Apparently this is not an uncommon issue with third-party temperature monitoring utilities and AMD CPUs:

Does HWMonitor say your CPU/APU temp is 70C when idling but your CPU socket feels cool to the touch? Is Core Temp only reading 10C but it's not possible because your room is 28C? The reason is that these and other 3rd party programs are not interpreting the AMD TCTL signal correctly, although they seem to work fine for Intel CPUs.

I'd say that the motherboard is the issue for both the inaccurate temps and the random shutdowns, the mbo of mine that had inaccurate temps was a older asus lga775 motherboard that would not perform a restart of any kind and that took 6 tries to get windows to install and had a variety of other quirks that led to it's swift replacement. I don't miss that board besides the fact it was my first computer.

Good read, thanks. I've tried three programs to see the temp, idle/ loaded. All three can't even reach the ambient/ room temperature and yea upon touching it's not really hot. So I would like to know more why I still get unwanted shutdowns.. What could possibly be causing all this, Sir?

try a heavy workload (say a aida64 benchmark or 3dmark)

perhaps that could make your cpu go to 100%. if its not, then you (possibly) really have a problem.

Did this also happen with your old power supply?

 

PCs shutting down at inappropriate times often involve the power supply, but it's hard to be sure at this point. Your wording makes it sound like you left the PC for some time and came back to find it had shut itself down? Maybe it's trying to go into Sleep mode, crashing, and then shutting down. If you intentionally order it to Sleep from the Start menu, what happens? Does it go to sleep and wake up properly?

 

I don't think its unusual for the CPU heatsink to feel somewhat cool… in fact it probably should feel cool if it's dissipating heat efficiently. I don't think it's possible to reduce a CPU's core temperature below ambient using air cooling, but even so, a low temperature shouldn't have anything to do with the problem you're describing.
