Best way to cool a portable PC in a tiny case

[Zack_Friedman]

Starting a new build soon using the Silverstone ML08 slimline case. Designing it to be portable, which is why the ML08's included handle will be great but the small case means that there's no room for any case fans. The case does have over-sized vents; But will that, in combination with the Intel stock CPU cooler, be enough to keep my Intel Core i5-3330 at a decent temperature? Or should I spend a few extra dollars on an aftermarket cooler like the Silverstone AR06? (link here) This particular PC will be used to run lighting equipment using a very lightweight application (Q Light Controller +) and on occasion some 3D visualization software (Magic 3D Easy View from Nicolaudie) on Windows 10.

An aftermarket cooler would be quieter but the stock cooler would be fine for the time being. The case is pretty much a Node 202 except with a different outer frame.

The stock cooler should be perfectly fine.
