Question coil whine on PSU, should I continue to use

[acoolrocket]

Thread title: My PSU coil whine that started a couple days ago has kept a constant semi-loud noise for sometime whilst I wait for my replacement, should I still use

Title pretty much, its a Corsair CX550F RGB, 80 PLUS Bronze (White). 1 and 1/2 years old.

As expected only happens when the PSU is underload so its not a fan issue. Its been happening for 3 days now since I'll have to wait the replacement PSU for about 2 weeks. Should I still use it? What if the noise incrementally becomes louder if such happens?
