AMD a8-5600k temperature reading

Edit: one of the fans faces GPU now
Alright this is really driving me kinda nuts, I recently upgraded from a Pentium Dual Core 3ghz to

AMD A8-5600K 3.6ghz Quadcore
Gigabyte F2A75M D3H
4GB DDR3 RAM
PowerColor HD7750 1GB
1.75 TB HDDs

Cooling info:
Aerocool Vs9, running stock heatsink, 3 intake 120mm fans(1x facing CPU side, 1x GPU, 1x front facing HDDs) and 1 exhaust 120mm fan at the back

And everything's basically fine except the temperature monitoring for the processor(A8-5600k), in the BIOS it's like 23 C even if 'System Temperature' was 36 C, is that even realistic? and in Windows 7 64bit I can't tell which temp it is using HWInfo64, HWmonitor, Gigabyte's easytune 6 and coretemp.

In HWinfo64 it kinda claims the CPU is 3-8 degrees

Then in Gigabyte's easy tune CPU is 20C so I traced it, and if you look in the picture, atleast according to Gigabyte it's Temperature 3, 16-21 C but that's kinda unrealistic as it also stays at 20+C even under full load.

Then finally in HWMonitor there's a 'Package' under AMD A8-5600K that says it's around 49-57 C but I'm still not sure which one is it.

What is that "package" anyway?

In fact one time Hwmonitor said 255 C was the max, but maybe that was because I was runinng 3 other temp monitors and it conflicted.(On the rest of the instances in this original post, I made sure to run one at a time).

I ran a Blend Test in Prime95 and both the TMPIN2('which is the same value as the 16-21C in Easytune and HWinfo64) and the A8-5600K 'Package' are changing and maxing at 22 C and 57 C respectively.

So all in all
SpeedFan, BIOS, HWinfo64 and ET6 all display 16-23 C or something,
HWMonitor and Speccy display the 49-57's

Which should I trust or what should I use?

Run the program one by one so they don't conflict. Also, AMD seems to break their temperature sensors more often than not, so be aware that strange readings are to be expected.

I made sure to do that on each of them, even trying more than one each day now
 
The TMPIN temps are pulled from your motherboard.

AMD's FM2 processors only have one temperature sensor on them, that is labeled the Package temperature. This temperature isn't as accurate as having a sensor on every core, but it is more accurate than using the motherboard sensor.
 
My A8 -5600K does the same thing. I use the ASRock AXTU program and GPU-z witch are very close and only show one temp. The individual cores do not read correctly.

Mine ran 56c under prime with the stock cooler @ 4Ghz So your package temp with HWMonitor 57c would be correct. But just use Gigabyte monitoring software
 
It's a general issue with the AMD Bulldozer CPUs. The package temp. is the temp. of the HS on the CPU. Sadly you can't read the core temps. :(

Yup, and this is the reason why people rarely clock above 65 degrees on AMD CPU's compared to the much higher temp allowance for Intel.

Someone suggested using GPU-Z and viewing the HD7560D temp and that it seems to give an accurate temperature reading for the entire chip. I tried it and it shows 44 C right now, different from Package and the temperature 3 16-21C previously reported. Do you think this could be correct? given I base the a8-5600k APU temp on its GPU using this?

You can't trust any temps. readings on AMD CPUs/APUs. As long as the HS temp. not exeed 65C you are good! :)

I've seen these kinds before but the problem is philippines Summer is dangerous to CPUs, so yeah I need to be able to accurately tell when I'm nearing 74C for me to determine if I need to use my tight budget on a heatsink or something
 
These CPUs are very aggressive with throttling, if it gets to hot it will throttle itself so you don't have to worry too much. In fact, all of the FM2 processors I've used start to throttle way before 74°C.

Alright given that, how do I detect these effectively? Playing games in Summer might get bothersome if it keeps throttling and thereby affecting performance, even when just normal internet use, having it suddenly slow down isn't cool
 
I use OCCT's Linpack test, it heats the processor up more than anything. Let it run for an hour or two and then look at the graphs it generates. The CPU speed graph will tell you if the processor is throttling, basically if the graph is switching back and forth between different speeds very quickly it is throttling, if it is staying at a pretty constant speed then it is not throttling.
 
I'm using HWInfo as well and these are my basis.

AMD specified max core temp is 74c
 
Hey we are living on the same country so we got the same weather. :) Try running IBT and see if it comes near those temps I posted.

hmmm alright. I have heard the temps get more accurate as they get hotter so maybe you just got yours hot enough to go that level so to speak. I'll try, I'm even tempted to disable my cooling just to see it do that
