TLDR: CPU frequency on newer notebooks always at 1.6+GHz; fans are always on and loud; Is it a CPU problem?

Edit: Thanks for the replies so far! After looking for alternatives we’ve been eyeing the Razer Blade 14, Zephyrus G14 and Zephyrus M16. If anyone has some experience with one of those devices, please let us know. Thank you!

Hello everyone!

Me and an acquaintance have recently bought new notebooks, one with an i9 13900H and one with an i7 12700H. We were both pretty unhappy with how loud the fans were even when basically doing nothing (had one tab in Firefox and the taskmanager open - using Windows 11). We found out, that the idle frequency of the CPUs on both devices was constantly quite high (min. 1.6GHz, most of the time even more, even though hwinfo tests showed that they should go down to ~0.8GHz). Our old notebooks (i7 8750, i7 7700) and a newer Thinkpad (i5 12500) don’t have this issue - the frequency drops to 0.8GHz and the fans turn off and stay silent. It’s possible to browse, code and do everything else that does not create much load on the CPU without the fans spinning up at all.

On all devices we used various tweaks (turning turbo boost off etc.), but it shows no effect on newer models.

So now we’re wondering if this is normal for newer notebooks (after 2018) or if there was something off with those notebooks in particular. Could AMD CPUs be better in that aspect?

We’ve both already returned those notebooks and can’t do further testing (tho even with the manufacturer support we found no solution).

If anyone has some more experience with that topic and maybe some insight on what we should look out for on new notebooks, any info is greatly appreciated! Thanks!

    Yes, this is pretty typical. Intel and AMD are currently battling for IPC and multi-threaded performance, efficiency be damned. AMD is definitely doing significantly better with efficiency, though. Check out some notebookcheck.net reviews of equivalent laptops between AMD and Intel, the Thinkpad T14s gen 3 is a great example. That T14s gen 3 AMD is a spectacular laptop, by the way, if you want a good balance of performance, build quality, battery, and quiet operation. We’ll see how the gen 4 does soon, but I have high hopes for the efficiency and performance of Zen4/RDNA3 in that machine, though I have a P14s gen 4 on order for 64GB of RAM.

    You will also typically get quieter operation in Linux, at least after the support of the machine has matured a bit. I’m excited to give the new AMD P-State EPP driver a try, which is going default with the new kernel that just released yesterday.

      Thanks, I’m quite happy with my work Thinkpad E14 Gen4 with a i5 12500, although that also doesn’t get completely silent, even though the fans are much more quiet than the Schenkers we had, especially in Idle.

      The Problem with all the Reviews I can find for pretty much all Notebooks, that they don’t really state how silent they really get, i.e. if the fans turn off at all. It seems that this is not a very common issue for most people.

      Right now I’m eying the Razer Blade 14 or the Asus Zephyrus G14, both using the Ryzen 9 7940HS, so if anyone has some experience with the fan noise of these or similar Notebooks (especially in a little bit tuned Linux environment), I would really like to hear some opinions - in another Comment we already discussed, that the G14 does not seem to get completely silent.

      I have made some good experience in this regard with my Blade 15 2018 which is completely silent, so it’s hard for me to swap to device that isn’t.
