Z6 G5 A - CPU upgrade

@djrwws,

Some thoughts:

1. Fan Control Settings in BIOS -I'm not familiar with your system, so see if this applies to you:

Check the BIOS settings to see if the fan speed control is configured properly. Many systems have an option to adjust how aggressively the fans respond to CPU temperatures.

You can enter the BIOS setup by pressing a key like Esc, F10, or Del during boot (the exact key will vary based on the system).

Look for fan settings under Hardware Monitor, Thermal, or Advanced options. Ensure the fan is set to Auto or a mode that scales with temperature.

2. HP Performance Advisor or Other Fan Control Software:

If you're using any software for fan control (such as HP Performance Advisor), make sure it is configured properly or try uninstalling/reinstalling it.

You might also want to check the Task Manager or HP Performance Advisor to see if the CPU workload correlates with the temperature spikes.

You can download the HP Performance Advisor from the official HP website. This tool helps optimize the performance of HP Workstations by providing system insights, recommendations, and customizable settings. Make sure to choose the correct version for your operating system.

3. Sensor Problem:

If the temperature sensor that controls the fan speed is malfunctioning, the fan might not respond correctly to temperature changes. Run diagnostics (HP offers a hardware diagnostic tool you can access by pressing F2 during startup) to check for hardware issues.

Try these steps to troubleshoot and let me know how it goes. If the problem persists, we can explore more in-depth solutions.

Kind Regards,

Thanks,

I’ve checked every option in bios and nothing there about cpu fan, you can just increase system fan at idle, which only has limited on cpu temp.

performance advisor can’t control cpu fan, but it is how I found out the cpu temp in the first place.

everything seems fine when I run the built in diagnostics.

I found a something on the AMD Community website that suggested running at 95C was quite normal for these processors when under-load. I seems difficult to get an absolute answer.

@djrwws,

I hope you are doing well.

Earlier in this discussion thread, I mentioned, quote: "increase overall airflow through your case AND especially through your CPU heatsink by adding one or more cooling fans".

With your indulgence, let me show you what that means to me, or rather, how I implemented this concept.

Here is exhibit "A": one of my heavily modified HP Z2 Tower G4 Workstations, as seen here: HP Z2 Tower G4 Workstation Performance Results - UserBenchmark.

Among other mods, I added two 90mm high-capacity (Blue-LED) cooling fans behind the front panel, one cooling fan on the side directly opposite the CPU heat sink (providing the CPU heat sink cool air directly), and one cooling fan on the bottom directly opposite the GPU (blowing in air directly into the GPU), and added 2-inch feet beneath the PC in order to give this fan some room to work properly.  All fans blowing air in the case -except the rear chassis fan and the power supply exhaust fan, which blows air out:

These cooling fans additions significantly lowered the overall CPU and GPU temps, especially when needed.  Unlike your PC though, all fans rev up very quickly and pick up quite a bit of speed/move lots of air when tasked to do so.

Kind Regards,

Wow, they're a bit bright.

There's not a lot of space in the Z6 G5 A chassis to fit more fans, no space at the front at all, but the side panel has vents and I think that I can fit 3x60mm fans to it, then I can add one internally to blow directly over the the cpu heat-sink.

I've heard back from tech. support at AMD who say that it's quite normal for the threadripper pro to sit at 95C under load, and nothing to worry about. This probably explains why the cpu fan doesn't seem to accelerate until it reaches 92C.

Thanks.
