Thanks for posting this. I have the loud fan issue. Its louder than the cheap power supply I use as a back-up. Runs even when sitting idle for about 20 minutes then quits. Then starts again 5 minutes later. Quite annoying. My IC-7300 and ft-891 do not have this issue. Buddy of mine has the same issue as you . He wrote Yaesu and has received no reply. This was 2 weeks ago. I believe that Yaesu is aware of the problem but simply won't directly address it yet. I'll be watching for updates.
If you get a moment, maybe post a video of what your fan sounds like. I hope to collect some data this week as well as make a short video of what my fan sounds like from the front and back. Even my FT-891 is quiet on RX and it has much less heat case to absorb the heat. I know it's picky but something is not correct.
Hello- If I change the setting in my service menu it does not remain at the new adjusted setting when I repower the unit. Is there a way to make the setting durable?
@@Helix_22 This noctua has half of static pressure of the original Panasonic ASFP60371 fan. Not sure how much it matters in 710 construction and air flow resistance.
