Martin said:This is hard to say exactly. The sensor chip (Nuvoton) has several temperature inputs and only the mainboard manufacturer knows exactly which of them are utilized and for which sources. Unfortunately they (ASUS) won't tell this. AFAIK on these models, ASUS reports only CPU and Mainboard temperature values and ignores the others.
While checking your issue, I found a bug in HWiNFO in reporting of sensor values for the MAXIMUS VI. I'll fix this in the next build released, however those Temp2/5 values will stay as they are now (voltage values will be fixed especially).
