Fanless power supply

Goodmorning everyone.

I have a card S5520GC which is housed inside a case SC5650DP .

I use the server as a workstation . My problem is that the fan supply is quite noisy , it was also new and now is getting worse .

I want to buy a new power supply , possibly fanless , can anyone suggest me what to buy ?

I do not have any extra power module , I have six hard drives and a video card , I just need a 600W power supply , I would just be sure you have all the cables needed to feed two processors , the board , the fans and hard drives .

I await your advice thanks
