temp sensors built in to the computer aren't always the most accurate, many times they can be off by 10 - 15 degrees. It also depends on which sensor. A socket sensor isn't the best. Generally the best one is the one built into the cpu but its not always accessable its not on the motherboard I have for my windows machine but was accessible in previous revisions to said motherboard.thebeephaha said:Well they read right from the temperature right from the computer's heat sensor so. Theres no reason for it to not be accurate.
