In many systems (certainly my Compaq Presario S5160UK) this chip is a winbond chip soldered onto, and an integral part of, the motherboard. I had believed that every way of determining system "temperatures" in software worked by reading the lower level software outputs of chips which actually measured the voltages of of certain diodes on the CPU, GPU, HDD and others, and performed the ADC function on them.
the other problem that the fan now is making lot of noise (i think normally the computer regulates the power of the fan regards the temperature).I have been reading a few posts where users have written that speccy gives more reliable measurements of "temperature" than speedfan. i think that the computer shuts down because it does not have the signal that the fan is working, i tried to wire the 3rd wire of then fan in the motherboard like it was but nothing changes (i think i should also wire the gnd so as the 3rd wire signal works? but the gnd now is with the external charger), or may be this is caused from another thing. I tried powering the fan from a phone charger with 5V, when I monitor the CPU voltage with speccy it seems that is good ( average 36°, but when not powering the fan the temperature keep rising until the laptop shutdown), but after few minutes the laptop keep beeping -discontinuous beep- for a while and then the it shuts down. "Depends, you have the gear, we cannot see", i'm sorry, i did not understand this. I removed that thirst wire from the plug just for testing, normally there are 3 wires in that connector. I have a condor laptop (nomad n14) with this mother board: “hannstar j 94v-0 e89382”, which has the fan stopped working, I get the fan off the motherboard and it worked fine, so I tried to measure the voltage that the motherboard is giving to the fan and I found that it is null (0 v), I searched the net and I found that this may be caused due to bios problem, so I removed the battery and the CMOS battery and clicked on the power button about 15 secs, and then putted the battery again, when I enter F2 options I find that the time has changed (I suppose that the bios is reseted, but the laptop did not take too much time to boot up, I red that it should take some time to boot up after BIOS reset, and the options in the F2 menu does not have bios reset option), but the fan is still not working, I tried to power the fan from the USB output, when I put both 5v and gnd from USB port it does not work, but when I put just the 5V from the USB port and the gnd from the normal fan motherboard connectors the fan works, but the Hard disk stops.
