This is a well known phenomenon in the electronics repair community.
The only correct option is to remove the glue.
Not all failures have been attributed to moisture. Some adhesives used for PCB assembly have been found to become conductive when exposed to high temperatures.

...or take a chance and use it with a silica gel pack or two near the PSU, you could put it inside the PSU but that's iffy and I would not recommend that.

For some reason silica gel is often treated like it is magic substance which deletes all water in significant radius. It is not. It absorbs limited amount of water at a limited rate. It is only useful inside of dry sealed container to mitigate water permeating through container walls and keep it dry for a limited amount of time.

When placed in open air it will quickly get saturated and do absolutely nothing.

So placing it near or inside the PSU will have the same effect as buying new caps and placing them near the PSU in a baggie.

learn to flipping read my guy, I said if you wanted to take a chance and risk it, I never said that was a proper fix... i'm starting to think most people here are idiots.

indeed it is well known among hardware repair groups but oddly not with retro computer people who seem to think psu for a pc holds 1000s of volts even when turned off and will kill if you even look inside it...

yeah the high temp shorting out glue is a problem too, but it's far less common in computer power supplies. it mostly effects crap PSUs from the early 00's aka the stuff hardly anyone would use.
But it's still something people should know about too

Does not matter why you suggested it - there is no "chance" here, you are suggesting actions which are completely useless and do nothing. This is spreading misinformation at best, intentionally harmful advice at worst - because suggesting obviously useless "fix" is harmful.

And then you call others names when you are called out on this. Straight into ignore list you go...
