Had some stuff come up, but here is the results from my testing.
Testing setup:
All tests were performed with the Framework laptop flat on a wood table.
Battery fully charged, connected to 60w Framework charger.
Used canned air to get any dust out of the heatsink before starting.
Windows 10 Pro 21H2, power profile set to max performance
i7-1165G7
32GB (2x16GB) 3200 running at 2666
Samsung 970 Pro 1TB
Stock Paste: Testing was done before removing the heatsink for the first time.
Idle: 43-45C, 2.6-5W, 1300MHz. let sit for ~15 minutes with only aida64 open to establish baseline. (did not have the CPU power line enabled for this screenshot)
CPU burn: 12.5 minute CPU only stress. temp leveled out at 91C, CPU clock held 4100MHz the whole time. CPU reported 23-24W no throttling.
let sit for ~10 minutes to come back down to base temperature.
CPU + FPU burn: 12 min CPU and FPU stress. quickly hit 100C but never went over, clock bounced between 3100-3600mhz, CPU reported 26-28W, heavy throttling once the temp hit 100C
Kryonaut Paste: Its just thermal paste, super easy to apply. cleaned the stock paste off with a paper towel and then cleaned the dies and heatsink with alcohol pads.
Idle: 40-42C. After applying past I let the laptop sit for ~15 minutes with only aida64 open to establish the baseline.
CPU burn: 13 minutes of CPU only stress. leveled out at 78-80C. CPU clock held 4100 MHz, 24w. no throttling.
let sit for ~10 minutes to come back down to base temperature.
CPU + FPU burn: 12 minutes of CPU and FPU stress. Quickly ramped up to hit 100C and throttled, once the fan caught up it dropped to 90-95C and stopped throttling hard. when the temp hit 95C it would throttle slightly and drop back to 90C. CPU was doing 3400-3600MHz, and 27-28w.
Honestly very impressive improvement over stock without the risk of damage from liquid metal. If you lift the laptop up slightly to improve the air intake you can get zero throttling once the fan ramps up under full load.
Conductonaut Liquid Metal: TBH I forgot how much this stuff sucks to apply. took me an hour to get it right and both the CPU and GPU die with the proper amount.
idle: once again, let it sit for a bit to get an idle baseline. 40-41C
CPU burn: Ran for 15 minutes. Leveled out at 72C, 4100 MHz.
let sit for ~10 minutes to come back down to base temperature.
CPU + FPU burn: 12 minutes, hit 95C and throttled, maintained 82C for the rest of the run. pretty much the same story as the Kryonaut but it only hit the limiter once at the start of the run.
I’m a bit surprised by the last result. The jump from the stock paste to the Kryonaut was 10C better on the CPU only run and 10C again on the CPU and FPU run. The jump to the Conductonaut for the CPU run was almost another 10C down, the CPU+FPU run was down 8C. I guess this might be the upper limit of the cooler itself or my application of the liquid metal was not perfect.
After all this I will be removing the liquid metal and putting Kryonaut back on. I’m not really going to be using this laptop hard in the long run.
