Uneven CPU thermals!

Ahh that explains the wattage discrepancy.

FWIW I did an r23 run with mine set to 65 and pulled up to 33w

Well my replaced motherboard from my other laptop was getting decent thermals, but the replacement one doesn’t. Before it was consistently getting 16k in Cinebench R23 and now I’m only getting around 15k.

The max core temp is 100c and the lowest core temp is 92c. I don’t recall the other laptop’s diff, but I don’t recall that big a difference.

I do also recall it hitting 4.3 GHz all cores consistently, but the replacement is at 4.16 GHz all cores consistently.

So clearly the other cooler or liquid metal was better applied than this replacement laptop.

It’s always something…

I’m going to cut my losses. My OG laptop has my dbrand skin too, which I’m going to lose out. At least the display is slightly better (I also give up on this), and the touchpad and spacers seem to be fitting better.

I’m just going to wait for the PTM to come in and just replace the one that’s on here. I don’t want to have to deal with swapping motherboards only to have to remove it again anyways to replace the TIM.

I may try swapping the display and the touchpad/spacers to see if I can keep my previous chassis with the dbrand skin on? I dunno… so much to try now that I have two FW16s to swap parts to see what fits better.

With the 7840HS CPU on the FW16.
We normally see cores 0-3 cooler than cores 4-7 in the amdgpu output.
Where are the cores on the die?
Looking at the FW16 laptop, are 0-3 on the left and 4-7 on the right or what?
My thought here is, when one removes the heat sink, which part of it are we expecting to be badly conducting heat, and thus which part are we expecting to lack paste/LM etc.
Is this affected by the orientation of the laptop when in normal use or in a backpack etc.

So I discovered with support that I have a way better score on CB23 without my dGPU installed (14500). But is that what’s to expect? I had 15k with my new mainboard and dGPU.

My problem is not the score or the performance itself. I don’t really care as for right now. I just can’t stand the raging fan noise all day long if not on saving mode (windows). I could go without dGPU to make is a bit less noisy, but my docking station has the cable management for the USB-C display output on the dGPU.

Max TDP of my CPU without dGPU is 48W with an average of 40W (That I find acceptable).
With dGPU it drops to 30W average (same 48W peak, but it’s in the first 10 seconds then it thermal throttles).

Support is as helping as possible but I’m at the “just clean your fans” step again.

I closed of Parts of the dGPU Vent Holes with black vinyl (roughly 5/8 on each Side (begin closing from the inside near the USB C Port as the highest frequency Noise is coming from the inner side vents)) That reduced the Fan Noise drasticly and it changes the pressure and Airflow to push alot more Air through the CPU Vents at the same Fan RPM.

I raised a similar question a while back and got crickets:

Swapping back to my old laptop, performance got worse! What used to be 16k is now at 14.5k and the delta between coolest and hottest core is larger!

Coolest core is 88.6c and hottest is 10c. Clearly the TIM was pumped out.

I guess it doesn’t matter…we just need to wait for the PTM TIM that Framework will send us to arrive.

Kudos to Framework to not give up on their customers after the final sale for sure.

If you don’t want to wait - the thermal grizzly has been working great for me. Its only like $10-15 for a pad.

And the Thermal Grizzly Phasesheet lasts for 4-5 “repastes” of a Laptop 16 :wink:

Yessir!

I used one sheet to do:
My CPU
My GPU
My steam deck

I have enough still to likely do:
My wife’s FW CPU and GPU

I’d be more than happy to. I’ll test again in about 6-8 weeks

Just did that, don’t know if that’s a placebo but it’s been an hour and I find it already better. Fans don’t speed as much and even when going crazy it sounds less annoying.

can you pleas elaborate on this a little bit more? I tried to run Cinebench R23 alone but got horrible results Perhaps this preset would help?

Its definitly not a placebo. The Airways for the dGPU are a little bit too big so the fan is loosing alot of its airmass through there. This airmass is more needed for the CPU. I didn’t test GPU Temps but they should be that bad. The GPU was never above 77C originally when using 100w.

I don’t think it’ll help you in this case, from your own report, the CPU was at 100*, so it was thermal throttling at that point.

Universal Tuning Utility is a third party software to adjust the AMD CPU’s power and thermal limits. It cannot really set limits higher than the max thermal throttle designed to safeguard the CPU however, so if you’re hitting 100*, no matter what the max power you set, it will throttle until it caps at 100*. The extreme power profile in UTU basically just unlocks all power limits aside from the thermal throttle, so it should force whatever the maximum performance is possible out of the heatsink design/efficiency.

You’ll probably need to repaste your default LM with a PTM pad to get better results. If you have some experience with this, it’s not too difficult, but if not, I’d recommend trying to get a RMA.

This is a good point. Did you apply the vinyl on the outside like a wrap, or block off the interior?

The GPU never gets anywhere near hot, so if it’s quieter and better on the CPU, I’ll give this a shot

Wrap it Baby :slight_smile:


Ah, very nice.
Those white blocks legs to add height?
I added some flipup feet under the space right near the usb modules which work pretty well for mine. Why’d you go with those blocks if I may ask?

Yes they are Legs that add height to the back to have it at a steeper angle. I like my keybords to be more angled than flat. And they add storage to have to extra expansion cards :slight_smile: I got with them because of the card storage. But the Feets are unused in my homesetup, as my device sits on a vesa stand. Still haven’t used them on the go.

What’s particularly amusing about this is that the first batch of those feet that I designed were a bit wider than I intended and covered some of the GPU airway–I adjusted them and re-printed to fix that–ironic :stuck_out_tongue:
