Acer Predator Helios 300 – How to Open & Apply Thermal Paste – Teardown



By request I’ve made a how to for the Predator Helios 300 on applying new thermal paste to the CPU/GPU.

If this is your first time applying thermal paste and you want to apply the paste then place the heatsink off then remove to see how it spread… Then DO NOT just set the heatsink back on. You should reapply the paste once you check how to spread otherwise you will create air bubbles.

This is my second how-to EVER. So please be gentle lol.
And before you say anything I KNOW MY CAMERA SUCKS. My wife had mine out of town..
OH WELL… Take it or leave it.

As you can see from the video, Acer was very liberal applying the thermal paste. So if you own this laptop I highly recommend you do this.

(It doesn’t void warranty, Acer tech support has told me as long as you don’t damage your unit during the process then no warranty will be compromised.)

My temps before this was at 95 C heavy gaming (With no under volt etc.) and after it reaches 80 C max.

Temps with ThrottleStop before this hit 76 C max and 71 C max afterwards running back to back tests of the FireStrike benchmark.

If you haven’t checked out my ThrottleStop video I highly recommend it. It also works for any laptop using the i7 7700hq not just the Helios.
