Can heat permanently affect PSU voltage stability?

[Sporos]

I'm looking for people with decent technical knowledge on power supplies, who can tell me if I may have borked up my power supply (Corsair sf600)

 

A while back I removed the sticker on my SF600 for aesthetic purposes using some alcohol and a little acetone. Some alcohol spilled inside the housing. I decided to dry it by hitting it with a hairdryer on low heat for 45 seconds to a minute.

 

I think it's equally possible that this was happening before and I just didn't notice, but after reassembling I noticed that there is a fair amount of audible coil whine coming from the psu. It's not great, but not terrible. I didn't mind much until I noticed that my new GPU (2080 super) is also whining louder than the PSU under load.

 

I guess my main question is; how likely is it that I caused this? Can heating a psu while unplugged cause a permanent impact on voltage stability, causing the Inductors in my GPU to work harder? Is it possible that I just melted the silicone on my coils a little, reducing the sound dampening?

 

I'd like to hear your take, Thank you.

The hair dryer didn't do shit.

It's normal for the power supply to be up to 60-80 degrees Celsius hot while you're in games.

Also, alcohol evaporates quite fast, you should have left it alone, alcohol would have been gone in around 3-5 minutes

 

Unscrew and screw back the case, maybe you misaligned it when screwing it back to case and now you get some vibrations amplified.

Otherwise... it's probably placebo, you're just paying more attention now than before.

You didn't do anything. The SF600 is a PSU that coilwhines with high end GPU-s and causes some of them to coilwhine.

I know, I'm just impatient sometimes

 

And you're probably right, thanks for the reassurance!

Okay, so it's not necessarily a sign of unstable voltages?

It probably isn't, the question is if you can tolerate it.

I can tolerate it just fine, just wanted to make sure it's not something worse.

 

Thank you

Some people have a rule they follow - if you suspect the PSU to have issues or be inadequate you go with a new PSU.

spilled what?

pure alcohol is organic solvent that will all evaporate, harmless to parts parts itself

something dirty may have spread on the transformer or other parts causing coilwhine
