What is your PCH temp?

[danoz0r]

Hi guys,

What and where is PCH ?

What is your PCH temp?

Mine is 60 degrees idle'ing(65-70 on load). While everything else is around 37 degrees. Is this normal?

What and where is PCH ?

Mine is actually reading differently in different programs! This actually popped up after I updated my UEFI to 1403.

In Corsair LINK, it lists the older temperature (1401), in the 30s (40s while gaming as it lays directly under the GPU)
In both the UEFI and AIDA 64, it lists the temperature in the 50s, with exceptionally minor changes.

With 1401, I only saw a spike into the 50s when I had moved my system fans to provide only indirect airflow. It's a case with the fans that mount on the HDD bays, and I had moved the one on there to the very front to draw in more actual fresh air, since it appeared to only push around air already in the case. I placed another fan back on the HDD bays, with direct airflow, and I saw a drop back to the 30s. In 1401, temperatures measured the same in UEFI, AIDA, and LINK.

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? *

I just said F**k it and bought a laser thermometer! No guessing about the temps showing on the screen, just dot that sucker and get correct temps.:D

Hahah i like the attitude 😄

Doesnt sound like a bad idea tho :cool:

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.

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.

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.

My PCH idle temp stays around 26c +/- @ 1.056V running default settings.
