OneDrive mirroring

Stop telling me that I am out of storage, I did not ask you to put my files there.

Nvidia Linux drivers

A 2 month old driver from a desktop 3070 failed to detect a laptop 3050, and I had to chroot to remove the offending driver, buuuut

Rescue USB

So it turns out the default Tumbleweed ISO is NOT a live image. Recue didn't work nor did usb boot until I realised. Burned LMDE onto the usb key, and I was able to get back up and running relatively quickly.

Even with direct-die water cooling, temps regularly spike into the 70s just while internet browsing.

I don't know if this is just cope, but I read somewhere that this is by design. These chips run very close to their thermal limit, because doing otherwise means you could squeeze extra performance out of it and are choosing not to. I switched from an i7-4790k to a r9-7950x3d (admittedly, a decade apart) and the thermal behavior is very different. The temps on the AMD chip shoot up very quickly, but I haven't seen them go out of spec like I've seen on the Intel. The Intel would generally stay cooler, but certain tasks like video encoding or Prime95 would drive it straight up to 100C and cause a thermal halt.

It is definitely by design. The current generations from both manufacturers are absurdly efficient at dissipating heat from the die. The 3D cache layer knocks off some thermal headroom, but the modern chips are smart enough to thermal throttle before they hit their rated thermal ceiling. This is part of why undervolting is so effective with the AM4 and AM5 chips. For what it's worth, the AM4 Ryzens do not have temp spikes like this. And Intel seems to be hell-bent on making toaster ovens...

Weird that a Haswell i7 would run that hot -- unless I'm misremembering, you might have had one with the shitty thermal paste between the die and IHS; it wasn't an issue on all Haswell and Ivy Bridge chips, but they definitely had some QC issues with the paste drying out during those generations. I also had a 4790k in a workstation machine that I tricked work into paying for, and even on just a 120mm AIO (without the delid/liquid metal treatment), it still stayed below 60-65C during thermal torture tests (Linpack and Prime95 small FFTs). Maybe I did delid it and bring in some spare LM from home; it was a long time and several dead brain cells ago.
