There is no need for that, why would you need it? fanS as in multiple fans for SSD? that is just overkill of overkills
Compatible SSDs with compatible heatsink will run just fine in the PS5, people have this weird idea that electronics must stay almost at room temp to work, while some components have operating temp even over 100C.
There are hundreds of ultrabooks with almost no air circulation around the SSD and they work fine. Of course it is good to have the ssd on "average temps", but that is archieved with heatsink + installing it like instructions say.
Do you also say that "so if you want a good car, it's still going to set you back like 500 000€/$", because there are also expensive cars on the market? There are also cheaper/smaller cars.
Same with SSD, it depends of the size and model, if you need only 512GB more -> it costs maybe 60-100€ with heatsink.
I got my 1TB WD SN850 with heatsink that I installed for around 150€ a month ago.
I could buy 2 tB WD SN850 for around 320€ + 10-20€ heatsink.
So even 2TB isnt even 400€, if you wait discounts that come often monthly.
And you didnt state currency/country so it is fair to assume that we can use €.
