Most importantly is that the way this is done is widely published. They simply convert the temperature they sense at that specific clock cycle into a hexadecimal number and provide that number to the chipset. It should also be noted that there is nothing secret, magical or proprietary about these sensors. If you really NEED the 5☌ the sensors may be off to keep your computer stable, then you have other issues, like inadequate case cooling. But they do need to be calibrated individually for the most accuracy and that's not happening except in critical medical/scientific devices.īut they don't have to be that precise either. That said, they still are accurate to within ±5% (typically well within ☓%) which is pretty darn good. The main problem is, these sensors cost less than a penny each and are not very high-tech. We need to know the temps when our systems are working hard, not when barely coasting.Īll the software based monitoring programs must monitor the same hardware based sensors. Click to expand.This is true but they are as accurate as you are going to get at that point in time! The problem is, those temps displayed in the BIOS Setup Menu are not that helpful because running the BIOS Setup Menu is probably the least demanding task we can ask of our computers.
