A NAND is a non-volatile flash memory type. As the ambient temperature rises, the slope of the CPU fan RPM line becomes increasingly steep.
So he …
The CPU fan hits it's top speed of just over 1500RPM when the ambient temperature gets to 39° C, but other than that the results are very straight-forward. With a linear trendline applied in Excel, we find that the average slope for the CPU fan is 13.263x, while the GPU fan slope is 6.9622x.
This eventually leads to slightly higher temperature values than those that would be reached under OS idling, which just adds to the impression that BIOS temperature values are just a hint to whether your computer has a good CPU temp.Therefore, if you haven’t cleaned it recently, there is a huge chance you have a ball of dust in your heatsink.
In other words, this temperature should only be a reference.Intel XTU is a very robust, great performance-tuning software that allows for serious overclocking, but more importantly, monitoring and stress testing a whole system, including CPU.

Of course, that works only if you have an Intel processor, otherwise you have to look for a different solution.Another downside of the Intel XTU is its stress testing that isn’t as efficient as some other tools (Prime95 or AIDA64) that are going to be mentioned later.
The reason is simple: a compressor blows the dust into the air and if you would do it inside of your house, you would just move the dust from the heatsink to your furniture, which is something you don’t want to do.From the scientific point of view, ambient room temperature is considered to be between 20°C/68°F and 26°C/79°F, with an average of 23°C/73°F. Ambient vs room temperature. Just like at idle, the CPU and GPU temperature slopes are very linear. Ok.
Ambient temperature: Store at the surrounding temperature. Since there are no official values, the only way to find the maximum temps is by searching the forums and reading about the other people’s experiences in this matter.After that very difficult step of finding out the answer to the question: “How hot should my CPU be?”, we are going to the next phase and that is how to monitor your CPU temperatures.If you are not that much into computers, there is a big chance you have no clue on how to check your CPU temp. A given component at a given load emits a constant Q at steady state and if you do the math on something that is completely passively cooled that operates 10 degrees above ambient at 25C, it only needs to operates at 8.3 degrees above ambient at 45C.On average, for every 1° C increase in ambient temperature, we saw the following increase in CPU/GPU temperature and fan speeds: This is less than our idle results, and is likely due to the dynamic fan throttling attempting to keep the CPU and GPU at a lower temperature. By applying a trendline with Excel (shown as black lines on the graph), we found that the slope for the CPU is actually 1.0469x, while the slope for the GPU is 1.0824x. Surprisingly, even with CPU and GPU fan throttling enabled, our results are very linear. With a linear trendline applied in Excel, we find that the average slope for the CPU fan is 30.691x (ignoring the points after 39° C) while the GPU fan slope is 6.4766x. Unfortunately, BIOS temperature reading has its limitations: it shows only the idle temperature and not the ones under heavy load. Because of that, it may be a solution to your problem – of course, only if you are absolutely sure that there is no faulty hardware in your configuration.

TJuction temperature won’t turn off your computer right away, it will first try to lower the temperature by reducing the power that reaches the CPU (throttle) and if that doesn’t succeed, it will turn off the processor to prevent any further damage.
