PCH Temperature?

Afternoon all

Just been having a look round my new Gigabyte Z77X-D3H bios and i came across this under the PC health status "pch temperature 56c" I have never seen this before on my other boards but the 56c it was reporting on did make me wonder what the hell is it? My CPU temp according to the bios was 26c and the motherboard temp was showing 30c. On my desktop core temp was showing my CPU at 26c stock speed at idle and my 7850 was at 28c.

Any idea what this pch temperature is?

Cheers guys

Not sure - Have same problem myself, was getting a PCH 60c temp warning, but no high tmps on CPU. Motherboard was a little high, but nothing terrible. Any ideas? Looks like equivalent of Southbridge.

Hi, Has anyone found any more info on this. Checking with EasyTune6 on my Gigabyte GA-Z77X-UD3H motherboard the temp is 59-69 deg but the defaul warning threshold is 40 deg. I raised a ticket with Gigabyte yesterday but no reply yet. Will update this when I do.

Dont trust easytune temps m8 theyre complete garbage, download HWinfo or another temp program.

According to easytune atm my CPU is 3 degrees. In HW info i have 2 PCH temps, i dunno what it means but one is same as my system temp bout 25 degs and the other is 43.5 degs min/max/average seems a bit wierd that it doesnt change at all. I dont trust sensors that dont change temp.

Hi BluD, Many thanks for the info. Gigabyte came back and told me to update the BIOS but didn't answer my question as to what the temo range for the PCH should be. Have asked them to clarify. Anyway, have found other posts about ET6 being useless and also several posts saying around 60 deg C was normal and an Intel spec sheet saying max of 108 deg C!! Have downloaded and run HWInfo64 and that is shwing 43.5.

Would be nice to geta definitive answer from Gigabyte. I will update if I get one.

Thanks again for the help

Update from Gigabyte.

According to intel spec, the max. temp of operation is about 100C.
We test a system currently runs at around 56C - 64C depending on processes being run.
You may skip the BIOS update if you dont want to.

I have the Gigabyte Z77M-D3H and I've posted about this. Without no cooling in my case at the moment (New build, case off etc) it sits @ 64 degrees and is hot to touch! Have a fan pointing at it at the moment and it sits at 45!
