What are these high temperatures?

Hello,

I recently build a new pc. The problem is that some temperatures are to 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?
Link

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


(Sorry for bad english. It isn´t my first language.)

Sounds like motherboard temps, but cross reference your CPU temps with another program like core temp.

I would be concerned with those temps too. What kind of case cooling do you have?

I have 1 system fan on the side of the pc.

Just one fan on the side? That could be your problem.

Do you not have a fan at the back, pulling air away from the motherboard/cpu and sending it out the back and away from the computer?

The back of the Fractial Design Core 1000 is too small, another fan wil not fit. :(

It looks like indeed, but it is to small, i already tried it.

The case came indeed with one fan on the front. but i moved the front fan to the side because it gives better temperatures. If i let the fan in the front, the temperatures would be much higher,

Too small for what size fan? if a 120mm won't fit, try a ~90mm etc.

Someone has to make a product for that space. I would also get another fan for the front. (whatever size it takes)

TMPIN0 is a faulty reading. There is no sensor there on MSI sandy bridge boards. I have a p67 chipset, saw my reading at 126C, wasn't getting crashes, but was concerned anyway. I replaced the TIM on the chipset -- no change. Did some more research, and found on a forum (MSI tech support I believe) where MSI said to basically ignore it.

What's going on is the hardware monitor is trying to calculate what the reading should be because there's no sensor.

It looks to me the case should have come with a pre installed intake fan on the front. If you don't have that, then you might want to ask back at the shop you bought it from.

In all, you should have 3 fans, 2 Intakes and 1 exhaust. Bear in Mind the power supply fan also plays a role in there.

Under load TMPIN0 is rising, so i think it is reading something. Did your TMPIN0 temperatures vary? (idle load)

Yes.

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 1.168v.

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

TMPIN0 sensor doesn't exist on your board. How can a hardware monitor read something that isn't there?

Contact MSI's technical support if you need clarification.

1) 1.68V is WAY too much for your CPU.
2) 1.6Ghz is the idle state for SB processors.
3) That sensor doesn't exist on MSI SB boards.

The reading is false. It doesn't matter that it's going up and down, HW monitor can't take a reading from a sensor that doesn't exists. I know, because I researched this same thing earlier this year. If you searched google, or contacted MSI's support, you'd get a definitive answer, since you're unwilling to believe me.

Is your CPU downclocking under load? Does your PC crash? If no and no, it's a non-issue.

Actually i forgot to type a 1. The standard voltage for my cpu is around 1.168.

I disabled all powersaving features in the bios. So the CPU shouldn´t clock back. As i write before: The cpu did clock back during load. It was when i was playing Unreal Tournament and Furmark. And it only happens when the TMPIN0 temperature was getting in the 100-120C range.
This i simply observed...

I contacted MSI support.

A high TMPIN0 temp reading isn't a "problem" because there's no sensor. It's a faulty reading you just need to ignore. I have an MSI P67 board, and it shoots up to 126C under load. It doesn't matter because the hardware monitor I'm using is wrong.

Return your BIOS settings back to what they should be, ignore TMPIN0, and use your computer as normal. If you still have issues, work through those one at a time. I have a feeling you've caused some of your current issues messing with settings.

I cant´t simply ignore it because when the temperature of TMPIN0 gets too high, my processor downclocks, even under load. That is a big problem.
I gonna try it with basic bios settings. Is your processor downclocking when the temperature of TMPIN0 exeeds 100C?

Since HWMonitor has no control over anything, something else in the system thinks something is too hot.

Something is probably too hot.

No, my processor never downclocks under load, my PC never crashes, and my TMPIN0 setting is usually pegged at 126C while gaming. It's a false reading.

You have something else going on.
