9 months agoCan you record the sound? I’ve never heard of a power supply having any kind of noisemaker. It’s probably just electrical interference or coil whine or something, where the waveform happens to produce that periodic sound. (You might even look around and find a nearby device changing its power draw with the same periodicity.)
Generally they’re for uneven surfaces like multiple chips on a PCB (RAM, SSDs, etc.) or where there’s a gap between the chip and the heatsink (e.g. something using the chassis as a heatsink).
There’s also thermal epoxy, which glues the heatsink to the chip, like with smaller cards that don’t expect to have the heatsink removed.
For a CPU or GPU, paste is still better.
