Standardized Framework 13 testing (WIP) thermals, battery life, performance, etc

Nice, could you post/point to how to increase the power limits? No rush or anything, I haven’t looked into it/just for the future

What werid behavior?

It seems to me that it’s working so well that the fan curve is now way off.

It takes longer before the fan ramps up than it did previously. Which means that the aluminum casing is (subjectively) warmer than it was previously… and that when I run something like Cinebench, it’s actually spiking up to like 95C before the fan kicks into a higher speed and eventually brings it down to 79C. (Screenshot below is from an earlier run).

I’m perplexed because while my temperatures and noise were downright magical in their improvement, it also benched far worse and didn’t reach the same power draw (multicore 567pts before, 488 after. 25.97W before, 21.85W after. Both plugged into the wall at 80% charge (my max)). Anyone have any idea why this might be?

I’ve repasted mine with liquid metal and it’s showing this behaviour as well. I think it’s just for some reason, there’s a huge delay between the temps rising and the fans kicking in. It could be intentionally so that fans turn on less, hence a quieter experience.

What I think may be involved as well is hotspot temperature versus core temps. While initially booting, I’ll see the hotspot temp get to around 100 C while the core temp is around 55 C to 60 C before the fans begin to really ramp.

Yeah, at this point I’m fairly sure this is the cause more than anything else at this point, that it’s basing the fan on a sensor that no longer heats up as quickly as it does when stock.

Slightly lower benchmark scores with PTM were reported in the past, in the PTM thread. Here’s some discussion of that: [Honeywell PTM7950 Phase Change Thermal Pads/Sheets] Application, Tips, and Results - #104 by Michael_Wu

With the ridiculously good results I got I wonder if there is some thing weird going on, is there someone selling regular thermal pads as tpm? It is also somewhat easy to break the stuff while applying, and if you got a hole/bubble with no contact that’s gonna hurt.

Edit: or it could be the stapm weirdness, I did notice during my ptm testing that it can cool more than 30W but after some time stapm clamps down to 30, which is still more than what stock paste can cool but less than what ptm can cool and usually less than it can cool with a temp limit of 80 (the stapm only comes down over 80 it seems). I do wonder how high ptm can go but I only figured out how to deal with the power limits after I switched to lm and I’d rather not change back just to test that now.

Though I just reread from the above quote that the behavior does also happen with liquid metal. So I’m wondering if disabling STAPM disables/messes with the “sensor that no longer heats up as quickly as it does when stock”, and/or there’s somewhere where the threshold can be changed. (also TBD on my end)
