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
https://www.yateloon.com/en/product-38837/DC-FAN-SERIES-120x120x25.html

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." 

 

Thank you

Basically any 12V fan of the appropriate dimensions should be usable - a high-RPM one like you have now, rather than a silent/low-speed one.

 

Ideally you want higher for both airflow and static pressure. I can't find a specification on pressure though.

And be very careful if you have the PSU open, the components in there can still kill you even unplugged if you don't know what your doing.

Well, when it isn't making the rattling noise, the fan noise is fine. It just becomes defected at times.

So I don't need to care about CFM? Just RPM? I mean, you could have rpm higher then 2200rpm, but worse CFM then currently?

TBH I've repaired a number of switch mode power supplies in the last year and even after only just being power off I read negligble voltages on the capacitors. Haven't died (or even felt a shock/tingling) yet..... I think most seem to have some kind of draining resistor....

Yeah, it's a legal requirement I think.

 

But you never know when you're going to run into the cheap one that ignored it, or one were it broke off somehow.
