Windows 10: Are Sony playing us?

Can anyone explain how Sony has managed to produce a slimline variation of PlayStations 2 3 & 4, without a fan yet retaining the same heat dissipation also apparently without loss of processing power and remaining as energy efficient? Is it incremental & clever miniaturisation or Is it worked out years before and therefore profiteering?

The blueray player doesn't play blueray discs on Sony wdws 10.

Original Title: Dlna

I have two laptops that I used to be able to place them side by side and transfer data/files wirelessly. They both have wifi.#1 sony wdws 10 #2 Lenovo wdws xp. The Sony had wdws Vista. The Sony also has dlna. I thought that it was the dlna that let transfer
files. Another issue with the Sony/wdws 10 the blue ray player doesn't play blue ray discs anymore plays regular DVD s the open/close button doesn't work.

The PlayStation 4 Slim does have a fan, it is a laptop styled blower fan.

Also, processors are becoming more energy efficient and can do more without creating more heat.
