What are these high temperatures?

Question

Hello,
I recently build a new pc. The problem is that some temperatures are t0o high. I am worried.
Temperatures after playing Unreal Tournament 3 for 25 minutes with a room temperature of 21 Celsius.
Temperatures after playing Unreal Tournament 3 for 20 minutes with a room temparture of 27 Celsius.
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.
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

Ok, i flashed the bios.
I saw that the system temperature(TMPIN2) was now 30C instead of 60. (chipset temps)
But TMPIN0 was just the same.
So i thought to run a few bad-scenario tests. i tested with a closed case without casefans with a room temperature of 19C.
I only tested with furmark because only when i use my graphiccard, TMPIN0 and TMPIN2 would raise to high temps.
Furmark only uses one CPU core.
This were the results:
As you can see TMPIN0/T1 reaches 120C, and my CPU downclocks again.
I located the sensor for TMPIN0, i think. I removed the sidepanel and placed a system fan directly under the videocard on the fintek chip. left tot the board.
The temperature dropped from 70C to 60C under furmark load. Other places and the results were less.
I also contacted MSI support. And they say that usually there is a temp sensor located close to the wintek chip. He also refered to the new betabios and said that the temps stayed that high, i should rma my board. And he closed my question thread.
quite stupid to place a sensor close to a pcie 16x slot, where people usually put hot gpu's. And the strange thing is that the temp of TMPIN0/T1 goes a lot higher than the graphic-card.
I touched almost the whole motherboard, but nothing is hot. and the hot air can't be hotter than 82.5C(GPU temp) So why does TMPIN0/T1 raise that much? 
I am going to order new casefans. Hoping they make a diference.
When i have the casefans and it is summer (30C). I think the casefans doesn't do much help then. I had more pc''s, they could easily get into a case without casefans especially at a room temperature of 19C at full load with hot graphic-card.
Why whould a CPU downclocks when a sensor under the PCIE slot get too hot? Why o WHY?!?!? it has nothing to do with the CPU itself! Even with IntelBurnTest the cpu stays below 60C and won't downclock.
It has to be a false reading, nothing gets too hot. Very annoying. I think the sensor is broken or something, when it reach a certain temperature it just keeps raising. it even kept raising  like 10 seconds after i quit furmark, and stayed for 20 seconds on 116/120C. it was 110 when i quit furmark. And if it is so important for msi to drop the cpu speed if TMPIN0/T1 Goes over 100C then lists this sensor to the bios temps and in msi controlcenter because they show not this temperature as of right now.
And i am not alone in this, atleast 2 more people have exact the same problem as me.

What temps are you seeing in control center?
and this:
They reporting the same temps as in HWmonitor and hwinfo. Actually Control Center only reports 2 temps: CPU temp and system temp.

Apparently this is a known issue and a beta me7 bios has been released.

1.Fix System Temp issue
Also, I got a response about the cpu compatibiltiy. All new boards shipments of that mobo are shipped with 2.1 and will apparently work with the sb cpu. (Like the z77 apparently, this chipset, the sb cpu and me 8 can co-exist w/o problem) That being said, flash to the .139 which is me7 then if the problem doesn't go away, hold your breath and try 2.1. We can give you a file to flash back to me7 if you need to do so.
About 2.1, i can't find nothing in the changelog about a fix for system-temperature. And i read that people couldn't boot anymore after they updated to ME8, they need an Ivy Bridge to boot. Well if that happens i can't flash back to ME7 since i don't have a Ivy Bridge. And the new beta bios has more fixes than 2.1
And xmad, after all these temp issues i feel like your avatar.
