Does anyone know where the mobo sensor is located on this mobo? Speedfan and Everest show high temp want to locate a fan.
 
Well if it's anything like the 680i, which it most likely is, then the Mobo Temp is taken directly off the IT8718F chip which is supposedly up near the DIMM slots. Now, I haven't tested this, so it may be completly wrong. But at least I did read it somewhere. I think it was on Lavalys forums, I'll see if I can find that old bookmark.

Nothing really conclusive I'm afraid, but at least it's a place to start.

Acording to this review, the IT8718F is located near the bottom just to the left of the SATA Ports.

Thanks, bottom link is for the Striker Extreme. Appreciate the effort.:)
 
Yes, I know about the bottom link, but there is precious little on this anywhere on the net it seems. I think I was more or less just illustrating that it's definitely not in the same place depending on whether the board is reference or not.

Regardless, nowadays(or at least in this generation) the mobo temp sensor seems invariably to be an embedded diode junction within the ITE chip which allows monitoring.
Now, to me this begs the question, "if it's embedded, how much internal electronics heat is it picking up in addition to ambient internal case temp".

btw. where's my damn CPU. Geeese it's taking a long time.

lol.
 
Hehe, I was just busting your chops after our PM tag yesterday. I'm totally fine with the shipping from my American friends.

Anyhow, you motivated me to find the temp sensor on this board, and I had some interesting results.
I took my can of compressed air and blew it on all the chips of my 680i. Interestingly enough, when I got to the Winbond chip directly to the right of the battery, the mobo temps dropped from 35 to 27DegC. So I went to the sensor section of Everest and sure enough, there it was. Winbond W83627DHG IO/system monitor chip. Then I typed 680i/winbond into google and came up with all kinds of stuff.

So I guess the board doesn't have an ITE monitor chip.

Your 780i has the same Winbond I/O chip btw. So, dime to a dollar that's where your Mobo sensor is as well.

I have the Winbond chip, but a fan directly on it does not change temp. My mobo sensor must be somewhere else. I have moved a fan all over can not find it.
 
Have you tried Everest? What does it say?

This is a very interesting problem. Both boards should be the same. Perhaps it was because I was using extremely cold compressed air? Give that a try. Regardless, if a simple change in case ambient is enough to effect the sensor, you'd think a fan blowing directly on it would do something. Maybe you're right, and the sensor is somewhere else on the 780i.
 
How high is the temp? If it's very high it's probably just reading from nowhere.

It was reading 70c in Everest and Speedfan. I am now running mixed prime at 445x9 with 1.4 vcore, all other voltages auto. Mobo temp reading 52c
