High CPU use/temps after recent Win10 update

Hi,

I've had my laptop for about 9 months now and after a few initial issues everything has been good.

A few months ago (maybe around April) I noticed that my CPU wasn't getting as hot anymore and the fans weren't coming on as much. I didn't notice any performance drop, however I have only played Factorio, Cities Skyines and Dyson Sphere Program on it, mainly Factorio. I assumed a Windows update had included some drivers that improved something so I didn't think anything else of it.

On Friday I had another Windows update and since then my CPU temps (and therefore fans) have shot up considerably. I see the CPU hitting 90C and then dropping due to the fans activating. One thing in particular I noticed was that when I had Factorio open it was around 70-80C, however if I Alt-Tab-ed to other open programs (in this case HWMonitor and Task Manager) so those programs were on top of Factorio (but it was still running behind them, not minimised), the CPU would drop to 50C as it was before. A simple click on Factorio to bring it into focus and then back to HWMonitor showed that caused a 10-20C increase (then the fans kicked in). I played around with some of the power profile options and none of them made a difference.

I restored my laptop to the previous Windows restore point (just before the latest updates were installed), and everything is back to how it was for the past few months, so there is definitely something in one of those updates which have caused this.

As I've been looking closely at the temps etc throughout this process, I *think* the CPU doesn't break about 1.6GHz without those latest drivers, which would explain things to some extent, but I'm not show how or why. I've searched online regarding this and the Windows updates which were supplied, but I couldn't find any useful information.

Does anyone have any ideas?

After researching a bit more (as far as I could as there is little information on the web about this), I've found a few other people with the same issue on various sites. Seems to be down to KB5005033, but why I don't know.

Any suggestions from anyone? I don't really like the idea of not putting Windows updates on my laptop, but then again I don't fancy my laptop melting when it does more than sit idle!

firstly check which process is using the cpu.

secondly it may require a repaste which is normal maintenance

start with those 2 things

KB5005033 is just a servicing roll-up, there's nothing in there that should cause issues. I've had it installed on my PC since 12th August.

It might not be the update, it might be your system. With the KB5005033 update uninstalled and your system running normally open an elevated command prompt and run these two commands...

dism /online /cleanup-image /checkhealth

This will check your component store for errors. Many updates use the component store libraries. If it says anything other than 'No component store corruption detected' the stop there and let us know.

sfc /scannow

This will check key system files for corruptions and try to fix them, it uses the compnent store which is why you run the dism command first. If this reports erros found and not fixed then you're best option is a reinstall.

If the dism command is clean and the sfc command finds errors that were corrected, then reboot and try installing KB5005033 again. I would unplug all external devices except mouse, keyboard and monitor when you install KB5005033.

My best assumption is either:

1) Windows is probably trying to download/install updates in the background (likely the same one you removed with the restore feature). Check the windows update in system settings + task manager to see if anything is running in the background more than usual

2) Try turning your fans on full when gaming. Although it is loud, it can be helpful during the summer months where ambient temperatures can cause an increase in overall system temperatures

3) If both of those don't work, try cleaning out your laptop with dust and/or do a re-paste of the components. Dust build-up is an unfortunate annoyance for any laptop owner, but it shouldn't be too difficult. I typically use thermal paste purifier + cotton buds to clean out my fans, with compressed air for the air vents

dism command was clean, sfc found a few issues which were corrected.

I reinstalled KB5005033 and sure enough the temps started to rise again. Small spikes in CPU usage raises the temps and then the fans kick in and it falls, no great issue with that, from what I gather temps of 90C for this CPU is normal before the fans kick in.

What I have noticed via HWMonitor my CPU Clocks hit ~4.3GHz whereas without KB5005033 it only hit ~1.7GHz. I confirmed this by uninstalling/reinstalling the patch and checking. So it looks like something in the patch had an adverse effect on my CPU max clock speed.

I'm not convinced that the update itself is at fault, I think it's more likely that there is some flaw or inconsistency in your system that the update is exposing

Need to try and figure out exactly how your CPU is behaving with and without the update installed. There have been a few reports of issues with the update but it's been more indicative of glitches rather than CPU behaviour.

Without the update in place, boot the system up into windows, open up HWMonitor and leave it for a while without doing anything. Make sure that your CPU usage is low so that you know updates etc aren't installing. Once you are happy that the system has settled run something intensive like a game (Still with HWMonitor running). Put the CPU through its paces. A good way of doing this is also Prime95 if you have that or wish to install it.

Once done, take note of the minimum CPU frequency, the maximum CPU frequency, the minimum utilisation and the maximum utilisation.

Install the update and then repeat the process.

At minimum I would expect your CPU clock speed to be quite low, the 1.7Ghz you mention wouldn't be unusual. This should only be the case when not doing anything though as it should spring into life (4.3Ghz) when under use.

If this isn't the case, the laptop wasn't operating correctly to begin with and will be performing better with the update.

If the CPU speed stays locked after the update then this would suggest that a power tweak may have been done. You may be able to fix this by going into the power settings and setting the minimum frequency to 5% (standard value).
