Acer has Incredible graphene thermal heatspreaders in their notebooks
If you looked into a modern acer notebook (i bought mine in 2025-09), you will see thick black stickers on many components, like the NVME SSD and SO-DIMM modules.
You may wonder why your SSD reached about 108°C (with and without the sticker) and the unmodified stock SO-DIMM 87°C with the sticker, with ambient air temperature of 26°C. Well dont ask me, iam wondering too.
And why the SSD is roughly 20°C cooler with a random noname 2mm thick heatsink with little airflow, as it touches the bottom cover.
Lets find out, lets test these stickers :)
What we will do here, is heat one of these stickers and a thin aluminium heatsink side by side up on one end, and using an IR camera and my fingers measure how well it conducts heat.
Left is a noname chinese aluminium heatsink, right is the acer black sticker. The precision laboratory hot plate used is at 108°C, the sticker on the outer side per IR camera is 31.4°C and is cool to the touch on the outer side. The heatsink is too hot to touch, aka it hurts if i touch it. The IR camera measures the outer part of the heatsink at 94.7°C
Why is acer putting these fake heat-spreader stickers on the components ?
