im extremely new, new as in last couple days. ive come across a issue where even under little resource usage the temps on my cpu itmediatly shoot upto 95c in a matter of seconds upon resuming, this happens nowhere else, even games or programs that use more.

also Ive heard about v7 having a advanced controll option, i would like to use my 9070xt for folding but upon starting it *only* uses 80%+ of my gpu, is there a way i can cap it so i can do other things and use FaH as like a idle game rather then vacuuming everything i have? is there something like that for 8.4? if not and i have to go back to v7 thats fine its just im on linux mint 22.2 and ive heard alot of compatibality issues with running those together.

There is no way and never was a way to control how much GPU you can use for FAH.
If your GPU or CPU are over heating, please check the cooling or improve the contact between heatsink and the chip of your device.
There are just a few things in the world which load GPU more than FAH, none of them are games

Strange. ive worked with 3d rendering, private hosting AI etc, guess i underestimated FaH. I think i may have found a way via creating a profile on LACT for the GPU, supposedly there may be a way to do this with the CPU too to reduce heat because ive read alot of other AMD users also are getting temp issues even with low loads.

however im getting compatibility issues which is seperate issue.

AMD users do not get temp issues. Users with incorrectly applied cooling solutions (or laptops) and whiteboxes have temp issues (Intel or AMD or nVidia).

its the cpu this issue is happening with, temp wise GPU has been chill af. cpu gets to 90c within a second of starting FaH even under low utilisation, low cores etc etc, it does not do this with anything else even other almost equally intensive programs like other rendering software, the cooling system has been maintained and upgraded recently, if it were incorrectly applied cooling, i would be getting these issues on other programs.

AMD CPUs, as well as Intel CPUs are designed for these temperatures.
AMD Zen 4 arch is always going to top out and stay at 95C regardless of cooling. Zen 5 will top out and stay at 90C or whatever lower you'll set in BIOS.
These temps are set by design, and that is not an issue

i've been using a cputhrottle program/script on my PCLinuxOS install HP lappy for a while now. Works just fine. When i need cooler temps, i just edit the file - easy peasy.

Have a beautiful day and be happy!

P.D. This is the script that ChatGPT developed for me for the previous version 7.x of FAH...

Code: Select all

#!/bin/bash

# Set thresholds (adjust to your preferred temps in millidegrees Celsius)
MAX_TEMP=80000

while true; do
    # Get current GPU temp
    GPU_TEMP=$(cat /sys/class/hwmon/hwmon1/temp1_input)
    
    # Check if Folding cores are running
    if pgrep FahCore_a8 > /dev/null; then
        CORE="FahCore_a8"
    elif pgrep FahCore_a9 > /dev/null; then
        CORE="FahCore_a9"
    else
        CORE=""
    fi

    if [[ -n $CORE ]]; then
        if (( GPU_TEMP > MAX_TEMP )); then
            echo "High GPU temp detected: $GPU_TEMP mC. Pausing Folding@Home core $CORE..."
            pkill -STOP $CORE
        else
            echo "GPU temp normal: $GPU_TEMP mC. Resuming Folding@Home core $CORE..."
            pkill -CONT $CORE
            cpulimit -e $CORE -l 60 -b
        fi
    else
        echo "No Folding@Home core running. Waiting..."
    fi

    sleep 60
done
