One of the wings on the cpu fan broke, the fan still spins, the temp is a bit higher - 46 celsius. Is it ok, or should I buy a new fan and how much does it cost?
This has never happened to me before, and I had trouble finding any info. If it happened to me, I would probably just get a new fan. The weight of the fan is unevan, and this puts unnecessary stress on the motor. I have know idea how much stress these motors can handle, but you don't want the possibility of the fan suddenly failing some day when you aren't in the room.
If it were me, I'd scrap the fan. But that's just me.
