ps5 slim or keep my launch ps5?

Couple of small things in the slim's favour: the disc drive is detachable, so a digital one can take a drive later, and storage goes from 825GB to 1TB. Neither is worth swapping a working console for on its own though. If the noise is fixed by cleaning, I'd keep the launch one.

depends which launch unit you've got, some were loud from day one and some are fine. the slim is quieter for most people but it isn't silent, and the gap is smaller than people make out. before spending money, pop the side covers off and clear the dust catcher holes. that alone fixes a lot of the noise and heat on older ones.
