byw7 Posted December 14, 2012 Share Posted December 14, 2012 Platform Controller Hub = PCH 1. What indicates this? 2. What temperature it is normal? 3. Which is too high? Kind Regards Quote Link to comment Share on other sites More sharing options...
Fiery Posted December 14, 2012 Share Posted December 14, 2012 PCH is the chipset component of your motherboard. It tends to run a bit hotter than processors, especially at idle. Anything above 80 Celsius is considered high for chipsets, and beyond 90 Celsius is considered critical. Regards, Fiery 1 Quote Link to comment Share on other sites More sharing options...

kpo6969 Posted January 4, 2013 Share Posted January 4, 2013 I have an Asrock Z77 Extreme4 and my PCH Diode has never changed once from 43C. That doesn't seem correct. Not even one degree up or down. Quote Link to comment Share on other sites More sharing options...

Have you tried the latest beta version of AIDA64 Extreme Edition? It's available for download at: http://www.aida64.com/downloads/aida64extremebuild2256z8l9qktcjyzip After upgrading to this new version, make sure to restart Windows to finalize the upgrade. If it's still stuck, then your motherboard may not be able to measure PCH temperature. Quote Link to comment Share on other sites More sharing options...

A PCH temperature of 84 Celsius is not considered critical for a mobile computer. Quote Link to comment Share on other sites More sharing options...
