Tom’s Programs — IT8718F Information

Just a little information about environmental controller part the ITE it8718f super i/o controller.

It can monitor the tachometer of 5 fans. Each fan Uses a 16 bit binary counter.

Each counter counts at 22.5 kHz. When a FAN_TAC pulse arrives, bits 15-8 are copied

to an eight bit register and bits 7-0 are copied to another eight bit register,

then the counter is reset and starts counting at 22.5 kHz again.

As a programmer I can make an equation like 1350000/(((bits 15-8 register*256)+bits 7-0 register)*2) to get the fan rpm. The 1350000 is 22.5khz * 60 so I get rpm and not revolutions per second. The *2 is because my fans have two pulses per revolution.

ITE named the inputs FAN_TAC1, FAN_TAC2, FAN_TAC3, FAN_TAC4, and FAN_TAC5.

It can monitor 3 temperatures. The temperature values are 8 bit two’s-complement -55c to +125c. Because ite chose to store these temperatures as two’s-complement, as a programmer I can just assign the register to a signed byte variable then print the variable to the screen

and it will handle the + and — ok.

ITE named the inputs TMPIN1, TMPIN2, and TMPIN3.

It can control the speed of 3 fans with pulse width modulation (pwm).

ITE named the outputs FAN_CTL1, FAN_CTL2, FAN_CTL3.

The 3 fan controllers in the it8718f can each be in one of 3 modes.

On/off mode. The fan will be off (stopped) or on (running full speed).

Smart guardian software mode. The fan speed will be determined by the PWM value entered into a register in it8718f by a software program. The pwm value is stored in bits 6-0 of a register. This is 0 for stopped and 127 for full speed.

Smart guardian Automatic mode. The fan speed will be determined by the values in the it8718f registers.

off temperature, At temperatures below this value the fan pwm value will be 0.

start temperature, At this temperature the fan will start with the start pwm value.

start PWM value, At start temperature this is the pwm value the fan will be running at.

slope PWM value, At temperatures above start temperature, for each degree increase in

temperature, pwm value will increase by slope PWM value. This is an 7 bit value. 4 bits for

the whole number part and 3 bits for the fractional part. this can be from 0 0/8 to 15 7/8.

The fractional part is bits 2-0 of a register.The whole number part is bits 5-3 of a register

and bit 7 of another register.

Direct-down control, Direct decreasing mode. As temperature decreases the pwm value will decrease by the slope pwm value for each degree decrease. Slow decreasing mode. As temperature decreases the pwm value will not decrease until the temperature has decreased the value of temperature interval. Then it will decrease by the slope pwm value.

temperature interval, In Slow decreasing mode this is the value temperature has to decrease before pwm value will decrease by slope pwm value. This is a 5 bit value, bits 4-0 of a register.

TMPIN1, TMPIN2, or TMPIN3, Each fan controller can use any of the TEMPIN’s to control it’s fan speed.

My ga-p35-ds3L motherboard uses these values.

off temperature 0

start temperature 20

start PWM value 35

slope PWM value 2.000

Direct-down control Slow decreasing mode

temperature interval 3

These are just my personal observations. Tom.

Tmpin3 what is

In fact, there are only four companies on the mainstream motherboard market: ITE Tech, Nuvoton, Microchip Technology and Fintek. Manufacturers of branded products IBM, HP, Dell, FSC, as a rule, use proprietary developments in motherboard circuitry and do not publish specifications for the controllers used. The circuitry of the motherboard assumes the presence of measurement circuits that are produced using analog-to-digital converters that convert the measured parameter into digital values, after which they can be transferred to another computing device on the board for further processing. The measurements made on the motherboard are mainly related to three groups of parameters: fan speed, temperature and voltage. The rotation speed of the fans used to cool the blocks and individual parts of the motherboard is usually controlled using tachometers built into the fan — usually a Hall sensor is used for this. nine0003

Question about iron temperature monitoring with hwmonitor. Topic started by thunder Start date The situation is as follows. People, tell me what these sensors show asus p8z77 v deluxe? Breed is blocked. Last edit: Reacts: thunder and WebWare Team. Brib said a:. This is not the current, what alarmed! This is the maximum allowable, it is clearly visible on the screen. Let’s think purely logically: at a temperature of more than C, the nose would certainly suggest that it smells like a burnt compound. nine0003

And since there is no such thing, then everywhere in the grid people are concerned about a similar «problem» and everywhere they say that these are phantom readings. And I argue like this: hwmonitor is a «combine» program. It was written as universal and intended for as many motherboards as possible. And somewhere these sensors are, but somewhere they are not, for example, Pro and Mini versions. Well, nothing in the PC can heat up to degrees!

The «hottest» places are vidyukha, CPU and PSU. There are coolers and protection everywhere. nine0 and, if it is not cheap, it will turn off the thermal protection, and the vidyuha will simply burn out.

When mining, they heat up according to the sensors up to and this is the limit for them. Further — blacken and charred. You learn right away! Reactions: ozi , thunder and valerian Codeby Dark Russian RU. Top bottom.

Thoughts I. Added: In fact, nichrome does not go to any sensor of the tmzin2 bridge-Does not go. In fact, in the diagram, this line connects the southerner and the myo controller — that’s it !! It doesn’t go close to any northern bridges at all. On page 6, after wiping our eyes, we find that it’s not a mistake for the southerner — I accidentally looked at the left edge of the page where the southerner is indicated there is just a diagram — but to the m2cpud line tmpin2 on ag8 thermda — all Bingo. On one page we see the power supply to the tmpin2 line, on the other we see its input to the myo. nine0003

I dug out, as I understood TMPIN2 is the north bridge, and TMPIN3 is the south, or TMPIN3 is some kind of phantom, and the south bridge is TMPIN1.

Question about iron temperature monitoring with hwmonitor

Important information. I ran a stability test in my native AMD overdrive and saw a temperature of 93 degrees, my Aida64 panic does not show anything, in HWinfo32 it also shows 93 degrees from the temperature3 sensor, I googled nothing really found, except that this is data from a non-existent sensor, maybe who can tell here? Thanks in advance. If the data in AIDA64 is idle, then the processor heats up.

Dear visitor!

I have mat. The program for controlling the speed of coolers shows a heating of 80 degrees. In principle, this does not affect the operation of the board in any way .. I found out about your problem before choosing for my purchase. Why did the choice fall on my board, because there is an ultradureyl cooling system. nine0003

I dug out, as I understood TMPIN2 is the north bridge, and TMPIN3 is the south, or TMPIN3 is some kind of phantom, and the south bridge is TMPIN1.
