Thermal throttling and thermal paste in Acer nitro 5 An-515-43

Baxic · January 3

Hello everyone, i was upgrading my ssd when i noticed a pink goo coming out under of my heatsink (Acer nitro 5 An-515-43). Fans were clean without much dust. Laptop thermal throttles sometimes. Is the paste original? I had it in shop once but they didnt say anything about thermal paste and i feel like manufacturers use those grey heatpads rather than this pink paste. So main questions: Should i change it? (if so buy paste or pads and which ones). Is it like this from factory?

Acer uses two different types of pad paste for the vram chips on their laptops, they sometimes use the pink and what is shown for the AN515-43 is the grey paste for the vram chips. In your laptop Acer used the pink pad paste so I wouldn't be worried that the paste is pink as its the correct paste.

For a 5 year old laptop like the AN515-43 I suggest that you change the paste the and pad thermal paste to a higher quality product like the Thermal Grizzly products as it's way overdue if you didn't change the paste. I recommend that you use their Conductonaut Extreme liquid metal for the CPU, Kryonaut Extreme that is a high performance paste for the gpu and the Minus Pad Extreme for the vram chips, as that is what I change my Nitro AN515-56 laptop to and it worked allot better and reduced temps by around 15C. overall

Below is what the AN515-43 service guide shows and its the grey paste, your AN515-43 must have the pink pad paste for its vram chips, and this spilling over is not a problem.
