Alarming Temp Readings In HWMonitor & Core Temp

[AbhieSpeaks]

Guys,

I recently built a APU based rig. Config is:

CPU - AMD A8 3870k (Not OCed)
MB - MSI A75 MA G55
PSU - Seasonic 430w
GPU - Sapphire 6670 DDR5 1GB
Cabinet - NZXT 210 Source Elite (Only Using Default Fans)
Cooler - CM Hyper 212 EVO
RAM - 2x4GB GSkill Sniper 1600MHz

The temp readings after only 5 mins are as per the screenshot of HWMonitor.

Please advice on what I need to do. What might be the possible reasons?
I removed the heatsink, cleared the thermal paste, cleaned, reapplied the compound after following a tutorial on best way to apply thermal compound.
Earlier I was able to complete few games for few hours before shutting down but now I can't even do that. Please help.

CPU temp? Alarming?

I think he means the TMPinx ones ,there 96c .

OP, I don't know on AMD MB but HWmonitor has a cpuin field on P8Z77 which has to be reporting wrong (max temps show higher the longer system is up an running .

Not familiar with were those sensors are on your MB .

Some temps are near 100*C, other are 6*C, yeah something is alarming lol.

Well i think those high temps are the motherboard, if you have a temperature sensor open the case up and see what temps the chipset heatsinks etc are at, if you don't have a sensor use your finger. Report back with findings/burnt finger :thumbsup:

To be honest all your temps look off. Could be a problem with the sensors.

What does this mean?

How can I confirm if the sensors are broke. Where can I find those.

System was shutting down after 2-3 hours automatically but after checking the heatsink and reapplying the shut down happens in the 1st 15 mins. Thats what I meant. What can I do here.

Temp across the board, heatsink etc are COLD yes not even warm. I guess there is some issue as all the temps mentioned are idle state temps. What could be the issue?

I meant the TMPIN0, TMPIN1, TMPIN2 readings. They go further that 100C sometimes.

So from what I've read, here's the situation (please correct me if I am mistaken):

- You had some automatic shutdown issues (which we are assuming is due to overheating).
- You checked HW Monitor and the temperature readings are on the fritz.
- You reapplied the heatsink but the CPU now shuts down even earlier.

Assuming this is the case, I'd personally go through the motions again to eliminate some variables. First, do what Max said and check the chipset temperatures. First degree burns are not necessary but please indicate to us if the chipset heatsinks were extra hot. If they are fine, I would download another temperature monitoring software (RealTemp or CoreTemp works fine) to make sure the issue is not the temperature software. If the core temp readings are indeed what they are, I'd go into the BIOS and ensure that all settings are at their default values. I'd then shutdown the computer for an hour or so to let the heatsink cool down, then I'd boot it up and let it idle while monitoring the temps to see if the issue is due to any kind of background apps you're running. If the temperature starts creeping up again, I would see what's running in the background that might be loading the chip. If everything looks normal, I'd start suspecting the chip is defective. If it doesn't shutdown on itself again, run a game and monitor the temperatures as you are playing. Hopefully this would give you an idea of what is causing the temperature spikes.

Of course, there are odd ball situations that I might not know of. For example, I have never dealt with running both Llano and a discrete GPU so there could possibly be an issue there as well.

I'll follow the mentioned procedure and report back after I get back home from office after say 6 hours. I touched each component earlier today but believe me everything was COLD no even warm. I'll try to find a temp monitor and note individual temps for each component. Can you suggest best places to take readings from the MB, CPU etc?

There is a possibility your chip doesn't like the way you are applying the thermal paste. There is also the possibility you have a bad chip, but that would be quite ....... rare.
