Yep, small Mige.
Relevante’s comment is probably not relevant (intentional pun) to your situation, as he is running a SimuCUBE system, if it was the std one from GD, people replaced the original fan with a noctua fan, as I had advised a few years ago.
In your case, you’re running an ionicube with a MW with integrated fan. So best to heed my advice and grab what I recommend above, together with a noctua 80mm fan simply to circulate air through your psu.
Just make sure the psu will fit in your housing, they have different dimensions to your existing psu.
