Gaming Z170X Owners, What is your PCH temp?

[microtech]

Hello all!

I have a Gigabyte Gaming 7 Z170X motherboard and absolutely love it!  I've got my 6700K overclocked to 4.5 and everything runs great.  I've been researching the heck out of everything and one thing strange I came across I can't seem to find the answer to.

On my Gaming 7 the PCH temperature will start out at about 28C on bootup, then over 10 or so minutes it climbs all the way up to like 38-40C and hangs out there.  From what I'm seeing that sounds a little high, especially when the computer is just completely idle.

So I wonder if other owners of the board (or even similar boards) can check what their PCH temperatures read?  Maybe this is normal... or maybe somehow the heatsink on the PCH area of my board isn't working as well as it should.

I'm getting some better exhaust fans, however right now my airflow is pretty dang awesome, everything else stays super cool.  For example my CPU is 23C idle and maxes at 54C under 100% load.  The second the load goes away its back down in the 20's C but the PCH never hardly moves.  Maybe 1 or 2 degrees down back to like 38C.

So is that a normal temperature or does my board have something weird going on?

For overclocking all I've done is set the multiplier to 45, the vcore voltage to 1.275 and then Load Line Calibration to HIGH.  Oh also my memory is in the XMP mode at 3000 15-15-15 1.35v.  It passes full 12+ hour stress tests like OCCT and Aida64.  The temps of the PCH stay right around that 40C under load. 

Thanks!

That is maybe normal on the PCH temp. I had a X79 boards and most of them run about the same temps. That is the big heatsink between the PCIEX slots & Sata ports.

Thanks for the reply, yes I think it may be as well but wondered for sure.  Just curious if other owners of the same board saw this temperature range too or what.  I'd think it with the heatsink it'd be lower but that's just me thinking.. not sure really haha

I have a Z170-HD3P and I notice that the chipset heat sink was very hot. It is a low profile and doesn't have fins. I fond a medium size heat sink (I have a box full of old heat sinks) that has a pink thermal paste and I just placed over the original. The temperature dropped dramatically. The system temperature is now about 10º above ambient temperature.
