This is a cooling fan for the PS5. I opened the package, but it's unused. I bought it at Yodobashi for 3980 yen, but it only works with the initial PS5 models (CHI-1××× series), so it was incompatible with my 2000 series (crying). If you have the initial PS5 model, how about taking this opportunity!! ※CFI-1××× series are the models without the black line on the body.
