My PSU fan every now and then makes a loud rattling noise. I opened it up, cleaned the dust and tried to see where I could put some oil in but the top is sealed. So looks like I'll have to replace it.
The current fan is a Yaln Fan D12SH-12 - 120mm, 12V, 2200rpm, 88.0 CFM and 40 dB
What specs do I need to look for when replacing the fan? Should the CFM be at least 88.0 CFM? Or is this the max? The PSU, Corsair VS650, states that the fan is "thermally controlled, so it only spins up when needed."
