I found in a local shop for 5 euros a 4mmx4mmx10mm 12v microvent and rotating on bearings .... i made a support with a fastron of the brico I have glued it with super attack to one of the fixing holes present on fan exterior frame and at this point I used to fix the fan in its seat a screw on that gold-colored strip, also visible in the picture above, which is the support of a printed one among the various in the vfo area. at this point instead of modifying the radio, which has never been in my programs, I have made an electrical cable extension which is then welded to the two fan cables, and then crosses the inside of the radio, immediately below the top cover, and comes out through one of the usual slots of airplane always on the top cover and then goes down to the 301 power supply, a diamond gsv 3000, and gets off the power from the clamps on all gsv 3000 under the front door they hold max.6ampere. the game is done .... just switched on the power supply immediately starts the fan that is virtually zero noise. I tried to turn on the radio by disabling the fan and after 15/20 minutes all the display area was pretty much the same as it was before, glowing ... at this point the test of the nine ... I connect the fan and after some soon all the area begins to noticeably lose heat as it is .... it is done !! there is not any hotter ... but just a very slight warmth just perceptible !! it works!! I have to add that I did not wash, welded wires to some printed on the radio and did not touch anything ... I just unplugged a screw, inserted it under the hole of the fastom / fan support, which worked properly, as you see it, it is immediately placed at the yaesu hole and then I screwed back the same screw that was screwed back immediately securing the fan in that space, which is always what we said a few days ago. I controlled and did not bump with anything, with the mechanisms of the vpho. so it works and I did not change the radio. I would say we are there. 73' franco it9ahh.
