What are these high temperatures?

[snowcake]

Hello,

I recently build a new pc. The problem is that some temperatures are too high. I am worried.

Temperatures after playing Unreal Tournament 3 for 25 minutes with a room temperature of 26 Celsius.




Temperatures after playing Unreal Tournament 3 for 20 minutes with a room temparture of 32 Celsius. (Normally it is never that warm in my room.)




There are 2 temperatures sensors which are bothering me. In Hwmonitor they are called TMPIN0 and TMPIN2. The bios system temperature is equal as TMPIN2. After some research i think it is the northbridge.

But what is TMPIN0? AIDA64 says it is the CPU. But that doesn't seem right because the temperature of TMPIN0 is higher than the CPU-cores and CPU-package.
The bios says the CPU temperature is equal as the CPU-cores and CPU-package which are displayed in HWmonitor and AIDA64.

When i going to stress my CPU, then the TMPIN0 temperature is not rising.
But when i stress my GPU, then the TMPIN0 temperature is rising. The TMPIN2(nortbridge?) is also rising since the northbridge is located close to the graphics-card.


Is 70 Degrees Celsius for the northbridge too high?
I found the “Maximium Case Temperature” for the Intel H61 Chipset: 111 Celsius.

But what is the “Maximium Case Temperature”? Has it to do something with Tcase?


I also found the Tcase and Tjmax for the Z68 chipset. The TCase for the set is 104°C and the Tjmax is 108°C. Link
As much as i can find, The H61 and Z68 are both 65 nm and have a max TDP of 6.1W. They are the same series. Is this also the case with the Tcase and Tjmax?

But what is TMPIN0 for a sensor?
My bios is showing only 2 temperatures: The cpu and the System Temperature. (Nortbridge Intel H61)

Should i be worried about the temperatures?


My system:
Intel pentium G860 Boxed
MSI-H61MA-E35 (B3) Intel H61 chipset
8GB ram, 2 dimms
Seageate Barracuda 7200 1TB
Fractial Design Core 1000
Antel vp350P
AMD Radeon HD4850

Try to use HWiNFO64/32, maybe it can idfentify those temps.

It can't be northbridge, because it's integrated in your CPU.

Since it comes from motherboard sensors, it's either southbridge or VRM MOSFETs. Most likely VRM.

I made a thread like this before with the exact same question. It seems that it is some kind of bug of false reading. HW Monitor always shows my TMPIN 1 and TMPIN 2 reaching 100+ Celsius after gaming. It doesn't really mean anything, that's what the other guys here said when I made that thread.

What she said.

HWMonitor doesn't play nice with other monitoring software. In my case, it was Asus' Probe. I'll bet you have some similar MSI software (probably came with your motherboard) running in the background. Turning it off will get you squared away.

I have played Unreal Tournament for about 10 minutes With a room temperature of 25 Celsius.
I did that because i wanted to feel how hot the heatsink of the chipset was. While i played, the temperatures rises. When the temperatures where high enough: 96 Celsius for TMPIN0 and 95 Celsius for TMPIN2 (the bios says it is system temperature and i think it is the chipset) in hwmonitor. I put of the sidepanel of the case. There is a fan connected to the sidepanel, but i let it connected to the mainboard.
Well, the Heatsink from the chipset doesn't feel like 95 degrees celsius. I can just touch it.


But now it happpens....

Because the sidepanel-fan can't do a proper airflow to the inner case anymore, the temperature of TMPIN0 is rising to 120 degrees! As you can see it here in the picture below. TMPIN2 stays at 95 degrees... And suddenly my processor downclocks to 1600mhz instead of 3ghz. The vcore is also dropping to 0.952 V instead of 1.68 V. For the information: I disabled all energy-saving settings in the bios.









The processor downclocking has nothing to do with TMPIN2 because i had more times these temperatures on TMPIN2 and the processor didn't downclock then. I had once TMPIN0 on 100 celsius and the processor didn't downclock, but it did downclock if the temperature of TMPIN0 exeeds 100/104 degrees celsius. Just as now.

But why downclocks the processor if the temperature is so high on TMPIN0? And what is TMPIN0? The cpu-cores and cpu-package and intel PCH are all under 60 degrees celsius.
The tcase of my processor is 69.1C and the Tj. Max is according to Core Temp 102C. So it is well below these temperatures...

What is even more strange, is that the temperatures for TMPIN0 is not shown in the bios and MSI Controlcenter. The bios and MSI controlcenter shows only two temperatures: CPU temp and System-temp which is equal to TMPIN2.

By the way... All monitorings programs are wrong about the +12v +5v.

But the crazy thing is this: The temperature of TMPIN0 is only rising if i stress my GPU. But when i stress the cpu then the TMPIN0 temperature is not rising at all, it stays the same as idle. But when TMPIN0 exeeds 100/104 Celsius my processor is getting downclocked to 1600mhz instead of 3ghz en the vcore is dropping to 0,952v instead of 1.68v.

What does this mean??? Why is TMPIN0 linked with my processor? Faulty motherboard?
