Need PSU capasitor nail polishing advice

[Mech0z]

I have this PSU https://www.overclock3d.net/reviews/power_supply/silver_power_sp-ss750m_750w_review/3

But I bought a Sapphire 290 Tri-X and with this card it often triggers coil whine (My old 7950 did not, at least it must have been less prominent)

I thought for a long time that it was the GPU, but I tried taking the PSU out of the case, and it comes form the PSU, and since there is no warranty left, I am considering trying to fix it myself it possible.

So is it possible to apply nail polish to capacitors to reduce vibration? And if yes, what about heat, do capacitors not get hot, I don't want to trap heat and make it kill it self

I really would recommend you not tamper with it and just get a new power supply, that review is 6 years ago, which means the psu is about the same age, just, yeah get a new one.

The problem I have with just buying a new is that its not even certain to fix the problem, from what I understand even some amazing new Seasonic PSUs have coilwhine

I would not recommend insulating capacitors with nail polish. They will only get hot and it probably won't fix the problem.

Nail polish is only given as advice to prevent from metallic components touching. e.g. when you delid intel CPUs you can put nail polish on the chips to prevent any liquid metal TIM from touching them.

Adding it to capacitors.. doable but I wouldnt like it. You are almost creating an insulator.
