Gigabyte GA-6VTXE RPM fan monitor

[dylant]

Hi all,
In a Gigabyte GA-6VTXE recapped and where the CPUfan header had a transistor burnt (replaced), the RPM fan monitor (CPUfan and SYSfan) don't work at all.
I think there is something wrong in the MOBO, there is anyone that know where is the RPM sensor or the circuitry for that device?

Thanks in advance.

Hi Dylant.

well, the fan header i believe is controlled by the I/O chip.... im not sure though. But one thing i do know is that the CPU temperature controller is a black thing under the CPU itself on some boards. The RPM is controlled in the BIOS depending on CPU temperature.
I had a person bring a PC to me the other day with an issue where the CPU fan would go nuts at times, sometimes at a cold temp it would go fast and directly opposite when hot, sometimes it went normal.... and that was on a recent GA-8iPE1000-G motherboard.

How did the transistor get burnt anyway? was there a fan over-current? are there burnt traces anywhere?

Is the fan working now? or is the fan still dead?

I believe that not all those programs work on all boards for example my Gigabyte GA-6VXE7+ board doesnt have any fan control software that will work with it.

Well, this is always integrated into the super IQ chip. Normaly some ITE or the like chips. I would not see this as an easy fix, unmles the problem is on the outer circuitry.

Yeah, my chip is an ITE its a mid sized one near the PCI ports i guess.
