The relay clicking can be solved easily with some putty:
The fan can be exchanged with the Noctua NF-A8 PWM, it gives considerable less noise.

Another small mod would be a shorter and thicker PS cable. I notice a considerable voltage drop with the long original cable. It gives some power drop from the radio at full power.

My IC-7300 is only half a year old. I have to wait till the end of august 2021 because I don't want to void the 2 year warranty. I might think different at that time.

Wow, that's a crazy loud relay at the back! I don't understand why it would be clicking like that anyway - I thought it would only latch once while you held the PTT down.
Anyway, it's an excellent solution to the problem :-)
Was that guy's body grounded, do you think? Lots of prodding around sensitive components.
The low frequency noise is reduced, but the higher frequency stuff is just as loud. The videographer has his sound meter on 'C' weighting, which is the wrong one for reflecting the human ear's response. He should have been using 'A' weighting.
