Replacing the fan in the Corsair CS750M power supply - tell me how best?

Question

Do it yourself

Based on the results of the proceedings on this topic:
forum.ixbt.com/topic.cgi?id=4:128643
, it was revealed that the noise in the computer comes from the PSU. I read the reviews in the markets - the problem is banal. The solution is also to change the fan.
There are a few questions:
1) Will any case fan with the correct size fit? (120x120) Which one is better? The goal is price/noise balance
2) Will the wires need to be changed? I watched this video:

There people unfastened the wires from the old fan and soldered them to the new one. Is there really no fan with the same connector on sale?
3) Isn't it possible to pour grease with a syringe directly into the fan? Here's a demo:

If it fails, what is better to fill in?

Answer 1

If the fan is collapsible, i.e. there is a plug behind which the end of the rotor axis with a split washer, then you can wash the axis and the bushing in the stator with lighter gasoline / alcohol from the remnants of the old grease and fill it with silicone for lubricating printers (it is thick like vyzelin). And be sure to close the cap well.

Answer 2

1) anyone will do, the main thing is that it fits on the mounts, it can be from the case, it can also be from the processor. which one is better, look at the market according to the parameters.
2) inside the power supply unit, the fan is most often simply soldered, less often it has a proprietary connector found only in this series of power supply units (now they practically do not install it due to economy), so you will have to solder any way, well, or cut in the middle and twist, which is worse.
3) it may well run, this is just the second point of getting rid of noise: 1. clean everything from dust 2. lubricate all moving parts 3. analyze air flows 4. replacement

Answer 3

I would suggest replacing rather than lubricating if possible. In practice, I can say that after lubrication, Carlson starts rattling again very soon.
