Heat sinks of this size are sufficient for the IRFP260. During operation, they keep about 60 degrees. The amplifier is over a year old and when using a transformer in the 24V / 16.6A power supply, it gives off about 2x8-10 watts. Unfortunately, with the classic power supply you can hear a slight humming noise, which is why I changed the power supply to pulse 24V / 8.6A. There are no disturbing sounds at the expense of a slight power reduction.
