    WOW! *I thought mine idling between 48-52C and under load between 60-65C was bad. *Is this the actual reading or is it an issue with the BIOS and other temp reading software being way off? *

    The PCH is within an area where when GPU is under load, hot air from it can make the temps higher.

    I have a Fury X with AIO, the rad is setup so hot air exhausts from it outside of case. I see ~6°C delta between idling/loaded system PCH temps, min 47°C max 53°C aver. 50°C over a course of running f@h for ~3hrs on CPU/GPU.

    In another thread on ROG forum, for this mobo, poster was seeing ~70°C, Raja@ASUS said it's not an issue.

    Why do PCH temps always run so high?

    Have you seen the tiny puny heatsinks on them? Not to mention Asus has started putting stickers on them, which is really bad for temps as well.

    For me the PCH Diode sits at 68 degrees celcius in a 32 degree ambient environment and 63 degrees in a 23 degree ambient environment. When gaming it gets up to at least 80 degrees at 32 degree ambient environment (probably more but I don't monitor with an OSD).

    On hot days it feels like the side panel of my computer case is giving off a boat load of heat, especially when gaming. So I have a feeling I just need to improve air flow because the heat feels like it isn't being sufficiently shunted to the back of the case like you'd expect it to be. For the time being I've been gaming with the front panel left open which greatly improves the air flow with my existing setup.

    I think it all BS really, its the diode temperature.

    Anyway highest I've seen 70 degrees with 39 degrees ambient temp (hottest day in aussie world - hit 43 outside that day)

    Normally see 60 max.
