Question How accurate are motherboard temp and voltage sensors?

[80251]

I'm guessing the CPU on-board sensors are probably pretty accurate but how accurate are motherboard temp and voltage sensors? I'm guessing manufacturers don't test each and every motherboard temp.&voltage sensor before issuing a QC approval?

Most sensors are +/- 5%. Use them as a gross gauge. They are good for comparisons to themselves over time. If you need more accuracy, then you need to look at higher cost sensors.
