Here is a good way to look at heat issue. And Power issues. After your system has been running M2TW for a few hours or when M2 achieves lock up re-boot and go into the SETUP bios dependent on your bios the key to hit to enter setup may be deferent mine is Delete key. In setup toggle around till you see “Power” or Power management yours may be different due to the differences in bios features on a given main board. What you are looking for under this menu is “Hardware Monitor” (again this may be called something else). Scroll down to that hit enter and you should see in real time everything your system is doing concerning heat and voltages.

Note: The only problem is how quickly you can open this the longer you take the cooler the system is going to become because there is no load on the system. Ideally the best is to have a hardware monitor you can launch from desktop like ones provided with your main board. But if your quick enough (10min or less) you should get some good results viewing this information in the SETUP bios.

Dependent upon what chip your running and the type of cooling you have these results will vary.

Mine running M2TW with a P4 CPU Asus main board. My system has 4 case fans two-70mm and two-30mm fans for optimal cooling. Have heat sink and fan on CPU which is a LGA775 chipset meaning my CPU has no pins that plug into the main board. It is a cool operating CPU because of it’s design, and a fan on Video card. I believe in cooling brothers. A cool system is a happy system. And powering it an 800watt power supply.

CPU 46 degrees C
MB temp 30 degrees C
CPU fan 3100 RPM
Chassis Fans 1350 RPM
Vcore voltage should not be lower than 1.0V; 1.2 to 1.5 is good if you notice low voltages occurring on the 5V and 12V lines you need a bigger power supply. This too can cause lockups when voltages are incorrect (to low for the system to operate properly).

CPU 46 C is like 145 degrees F
If your CPU is AMD or Celeron they may be a little hotter but you do not want this to be 90 to 114 degrees C that’s like 200+ degrees F. Many CPU’s will start to crumble at that heat. Even though I have never seen mine go above 86C or around 185F and that’s when I forget to turn the air conditioner on in the room I have my PC in.

Main boards around 30 to 50C is normal if your main board is any hotter your going to start effecting the way memory runs. Good heat sinks on memory sticks are necessary.

CPU fan speeds 2000 RPM or lower means your CPU is going to heat up even more and no case fans will eventually destroy the processor or shorten it’s life span. Also make sure the fan is mounted properly to the CPU sometime just by moving the System around can cause the fan to come a little lose it really needs to sit snugly to the CPU or heat sink. With no case fans all you start doing is blowing around hot air. Case fans pull in cooler air thus expelling the hotter air. Over clocking the CPU and running a system without cooling means your killing your computer even faster one day at a time.

These are just over all specs were as running liquid cooling your CPU should never be over 15 to 25C under any load. If it is there is something wrong with the circulation or radiator in the liquid cooling system or water is low.

Check your systems make sure your lockups are not heat related. Or even voltage related. Please post your findings here so others can see and compare the results to their systems.

Rock on my brothers and may your systems always run cool.
