Is it safe to wrap a PSU as part of a mod?

Heya guys,

So this might be a very dumb question for you all, but I'm rather unsure about it and hence want to ask all of you modders out there...

Would it be possible to use something like a noise dampening kit and put over a PSU, in order to cover the stickers etc on it, for a more cleaner look?

Ie, to tape the dampening film on the sides of the PSU, just to cover the top stickers.

Will this have any effects on the PSUs temps? Ie, do you think that the film might get damaged or maybe a bit paranoid, but even start to burn?...

The kit is this: https://www.inet.se/produkt/8500207/...ulltower-svart

And thinking of putting it on an Corsair RM1000x PSU.

Or do you guys maybe have a smarter way of doing this?... I have an Fractal Design Define C TG case and it has a small see through for the PSU in the PSU shroud, which is what I'm trying to get a more cleaner look, rather than having the sticker show through:


Thanks folks,
Dawelio

If you don't cover PSU ventilation openings, you can pretty much do whatever you want. If your case fan will be pointing down, and you want to cover the sticker on the back so it wouldn't be seen through the PSU shroud there will be no problem. Only thing to have in mind if you want to wrap you PSU, in car wrap foil for example, is to always have metal to metal contact with the case. Usually enough through the screws. PSU casing is grounded, and it will ground your case too if there is short somewhere, and keep you safe.

The only problem I can see is that you are adding a thermal jacket onto the PSU (regardless of not blocking any vents) and it may thus run warmer and the fan spin up more often.

As long as the airflow through PSU is not obstructed it wouldn't matter even if you wrap it in wool. Casing doesn't have enough surface, thermal mass, or contact with heating components to make the difference in temps. That is why there are heat sinks inside PSU, and fan blowing over them.

There is hardly any heat / watt dissipation through the walls at all. Wouldn't matter what you covered it with as long as the vent is free.

You do realise that 90% of modern PSUs do not spin the fan at all until they get to a certain temp, right?

As I was saying, wrap it in a thermal jacket and it will reach those temps much faster. Especially if you put something on the top as the heat rises.

So if he can live with his fan going most of the time? fair play. I've had plenty of experience with that foam and trust me it's a real heat insulator. Alienware used to use it. Note, used to. No one uses it now.

Quite funny you mention that because I have done exactly what he wants on my old Seasonic 850w. There was no difference before and after. In fact I had the foam + Acrylic plating which I used as a shelf. I disagree with you on the "real heat insulator".

My reasoning was the foam + acrylic was the perfect width to support a shelf I used as a watercooling passthrough.

Science - any insulator (note, the clue is in the name of it) for sound or heat is pretty much the same. It is a dense material used to absorb.

It may not have made enough of a difference to bother you, but it will make a difference. He may as well get a square of 3mm acrylic cut and just plonk that on top.

Negligable difference in my opinion. Your wording though seems to greatly exaggerate it.
I am running my pc in Shadows of war right now. Touching the PSU under a pretty heavy load, and the PSU is still very cool to the touch. Cant see how it makes any difference so saying his fan will be going off most of the time is a bit much.

And before you jump in and say "well its because the fan is going" It is covered with a PSU shroud that has no airflow from the PC itself.

I exaggerate everything dude. That's Autism for you !

I bet if you grabbed a thermal camera and tested it though it would be pretty bad. Especially if the fan isn't running. That insulator is good at what it does (deaden noise) but like I said, it's like a thermal blanket. I bet if you had one of those heat scope things and looked at the shell of the PSU through it, then put that stuff over it? you would see hardly any heat at all on the outside.
