Questions about a Ryzen 5 3500U

[eternalium]

Hello.

About half a year ago, I bought the ultrabook Acer Swift 3, SF314-41G to be specific, which has 3500U and Radeon 540X. I coupled the soldered 4GB memory with an 8GB stick, achieving the maximum amount of 12GBs (the clock times and speeds match up). I need discrete graphics and Radeon 540X is enough for my needs. But unfortunately, there is a catch...

Up until recently, about 2 months ago, the machine started to throttle very easily, even while it's not warm to the touch. Moreover, I'm using a cooler and the laptop's fan is at max speed, using NoteBook FanControl (it never throttled before while only using a cooler and not the software). So I started to monitor the temperatures while also doing specific tests. Hitting only the dGPU with maximum load using FurMark leads to a sustained performance with just shy of the thermal limit. But when the CPU is used even a little, the temperatures go over the, for some reason very low, threshold of 65C and it throttles heavily. The machine never goes above 70 degrees.

So, my question is;

Is there a fix for these issues with this combination of CPU and GPU?
Or should I use my extensive warranty if these issues are out of ordinary and try to get a replacement? (or at least try to have them fixed)

Thank you.

Edit: I remembered about how I used to do 3D intensive works on battery, and while on the go, without any cooling and it never throttled either. I'm starting to assume that some updates broke things and the best I can do is try to get a replacement.

HWinfo in sensor mode picks up a lot of extra temperature sensors (if they are present), do any of them read higher numbers?

The values on the GPU, both Task Manager and HWMonitor, are correct, as they don't jump up and down, but the CPU can go up and down very quickly, spiking with boosts, going down immediately when the load is off, etc. If you mean other values such as motherboard and storage, they are just fine, almost always below 50, or even 45.

It didn't surprise me much, since my old laptop would report 95+ degrees immediately to ramp up the fans, or at least I try to believe in that. Maybe I'm just very unlucky with thermals on laptops.

HWmonitor is the free gimped version of HWinfo, except HWinfo is also free. I dont know why anyone still uses HWmonitor.

 

It's also not reading the CPU per core temperatures which doesnt help.

I've read about Ryzen Controller, anything I can do with that?
