4GB should be enough. If not, it is one of the easiest upgrades to do on a PC.


You can also add a dust filter to your pc.

It's fairly important.

Dust acts as an insulator, and as more builds up, it will slowly and progressively reduce the effectiveness of fans and radiator fins.

Filters greatly help reduce dust buildup, though they do restrict airflow a small amount.

You can McGuyver up some from foam like this stuff and a pair of scissors, and put it in front of intake fans for desktops. I put mine in front of the metal 'cage' that my intake fan is behind, and then closed the front panel over it. It works well.

For my laptop, a used dryer sheet (don't use a fresh one, I have no idea what the fabric softener stuff will do) trimmed to size and taped over the fan intake on the outside of the case works well. It can be hidden if you're willing to open the laptop and put it in the inside of the bottom plate of most laptops. (Mine comes off as 1 piece, exposing all of the internals).

Ah ok. That makes sense. In terms of open cell foam, do you think this would be adequate? I would most likely want to cut and adhere the material to the inside walls of the compartment, right?

ahh, sure so if you can force air in through filters you get only clean air in, sure, what sort of fans and cases are good for that? because I guess you need some decent intake fans to pull air through the foam filters? (this is like what my case has, fairly thin so air moves through it) https://www.amazon.com/Uni-Filter-BF-2-30-PPI-Coarse/dp/B000ONZT5Y
