Question CPU high speed and high temps while idle

[nalcz]

I have just finished building my PC and my CPU keeps running at super high speeds even when it's idle and the CPU load is less than 10%

The CPU is Ryzen 5 5600x (3.7GHz and 4.4GHz turbo). As you can see in the NZXT Cam screenshot below, it never goes below it's base clock and the temperature is alwas around 75-95°C with the CPU fan at it's top speed.

What I have tried so far:

• changing the windows power options to Balanced and Power saver
• reseting the BIOS setting to the recommended defaults

Minus the temperature you're reporting, it's supposed to do that. Cpus from both AMD and Intel do that by design, just not in the same manner.
Take a look at HWINFO and you can see how fast each core is running and how much they're doing. Ignore CAM's load, temperature, and speed. It's just not reliable if it only looks at the whole cpu.

As for temperature, probably an incorrect cooler mount, but you've not provided much to go on in regards to that.
-cpu cooler
-case model
You know, cooling related stuff.

Get HWInfo64 and stop running the CAM software.

IF you do, you'll probably see individual cores running down as low as 3600Mhz or so (depends on your power plan settings and task activity level) but no lower. When a core truly is idle it will drop into C6 deep sleep where it's basically turned off so 0 clock. It can't report that though because it would wake up so it instead reports the last clock (usually 3600Mhz or so) before dropping into C6.

HWInfo has a metric showing the percent of time each core's in C6 (deep sleep), C1 (low power) and C0 (full power).

The case is NZXT H1 v1 and the CPU cooler is a NZXT 140mm AIO cooler that came with the case

This is the full HWMonitor report where you can see more info about the CPU:

Not HWMonitor...HWInfo64. What you need to see are the Package C State Residency metrics and only HWInfo shows that.

From what I can see of HWMonitor, though, it all appears perfectly normal. Keeping in mind it doesn't show much, especially CPU core voltage averages and Tdie core temperature averages. You have to use an average temp and core voltage because the processor is very dynamic.... constantly boosting and idling raising and lowering voltage along with it much faster than monitoring apps can keep up with it. Min's, Max's and Current is useful but not telling the whole story.

No HWMonitor. HWINFO, please.
So dumb of HWMonitor to post the less useful motherboard temperature sensors at the top...

Here you go

Wait - Version 1, and not Version 2? Why the heck is NZXT still selling Version 1?

You can click the right arrow on Core Clocks and see what all the cores are running at.
Under Core Utility, you can see which cores are doing anything. As of the screenshot, it's just Core 0 and Core 5 really doing anything.


After that... cpu cooler installation and fan orientation. Shouldn't have been too hard to do...

So...in the period of time HWInfo was running the CPU in aggregate was about 82% of the time in either C6 or C1, mostly C1. In C6 the cores are basically turned off, in C1 I believe they're still ticking over at base clock, about 3600Mhz.

The CPU is definitely 'doing' something with one core averaging 50% utility, another 30% with the rest bouncing around; CPU die (average) temp AVERAGE was in low 80's so pretty warm. The GPU clock average is running high (1.7Ghz) too.

In a game or does a 1080 always run hot with high clocks even in text mode only? If so, are you still running that CAM software? it's known (especially the older version) to play havoc with Ryzen CPU's and not let them drop into C6 very often. Maybe that's why it's not in C6 over 80% of the time if you think it's "idle".

And unrelated: I don't know what memory you have but you might should enable XMP (DOCP for Asus) to see better than 2400 speed because that's all it's doing for you right now. Of course, if it's only 2400 rated memory...then never mind!
