Where does these values come from ?
My qs are as follows;
1. how does the motherboard calculates the rpm of fan(s) 2. the votages are given like this +5V, +12V etc and these start from zero thats wht i think. but the motherboard show from -3.22V to +5 V. my qs is if the negative side increases does it have some kinda of effect on the overall voltage? (voltage diff is increasing but max +5V remains same) bye |

(voltage diff is increasing but max +5V remains same) bye forget the negative voltage values - it's mostly incorrect metered only the positive voltage values are correctly metered |

Hi "Aamir"
1. how does the motherboard calculates the rpm of fan(s) Fans with 3 wires have what is called a Tachogenerator on them, chips on the motherboard use this signal to report RPM from the motor. 2. the votages are given like this +5V, +12V etc and these start from zero thats wht i think. but the motherboard show from -3.22V to +5 V. my qs is if the negative side increases does it have some kinda of effect on the overall voltage? (voltage diff is increasing but max +5V remains same) Any unwelcome voltage change spells trouble. -- (º·.?(?*·.? ?.·*?)?.·º) «.·°·. Steve .·°·.» (?.·º(?.·?* *?·.?)º·.?) |
