Or even more likely, they just doubled the fan speed so that they could get away with much smaller heat sinks. : PWhat is more likely is that Sony (or its partner AMD) has optimized power delivery of the SoC, which enabled it to reduce power consumption of the chip and allowed to use a lighter cooling system and/or a different PSU.
I don't think any of that would improve availability. If anything is limiting production, it's going to be components like the processor and other chips. Cutting costs is to improve their bottom line, and won't likely improve the pricing or availability of the hardware anytime soon.Shocking that PS5 is still so hard to find for sale, anywhere. Glad that Sony is reducing costs, weight, and/or power consumption. Need more units for sale!
