Thanks. . . .

I would save your time and money on that mod.

Below is a simple mod I did to mine to place a small fan dead center on the heatsink where most of the wasted heat energy is concentrated. It plugs into a DC power out jack in the rear and slip fits into the fins of the heatsink. No dust is drawn into the receiver cabinet and it is quiet as well.

Thanks -- so this is drawing air OUT not pushing in, right? Can you supply the specific typek/Serial Number of the fanS?
And what type of standoff spacers are on it?

Sorry, I see now that the heatsink has no pass through to the receiver so obviously this would be to just take heat off the sink

It is a random 12V fan. It cools down the regulator/rectifier heatsink where a majority of the wasted heat is generated. I have used it since the radio was new. The cabinet gets barely warm. The standoffs were from a junk drawer and were chosen to fit with friction, and heat shrnk, between the fins. The shroud is simply tape to fill the gap to top of fins.

I did the same thing when I purchased my R9000.
For mine, I used a 120mm case fan with a 3 speed selector switch which I set on the s;lowest speed to minimize fan noise. It turned out moving plenty of air when I was all done.
I was able to work some tiny wire ties through the ventilation slots on the rear panel next to the heatsink. I wanted to try and remove any heat from the components like the CPU etc. Mine pulls air through the vent slots in the rear chassis. Not sure where it gets the air from as I've never discovered any dust accumulations when I open the radio up. I know it does pull hot air out though if I leave the fan off and power the 900 for 30 minutes or so. I get a decent amount of warn (not hot) air for about 10 minutes or so and then it cools to just above ambient temp.

I also used the 12VDC barrel jack power connector on the rear of the R9000. Running the fan on the slowest speed kept it pretty much inaudible for years now. But... the other day I started hearing an odd noise. It was my R9000 cooling fan. I removed it and opened it up and I was able to clean it very well plus lubricate it and pop it back together. It had a fair amount of dust buildup on the fan blades and some around the slotted vents on the R9000 rear panel but nothing alarming considering how many years the fan has been operating.
I don't know the model of fan but it's an older Antec model that has real ball bearings and a 3-speed switch. It also had the 3rd tachometer output wire for computer use which is not used of course for the R9000 cooling.

The whole thing used things from the misc parts bins to hold it in place over the R9000s vet slots on the rear panel.
After I mounted the fan using wire ties, it wanted to slip down as the wire ties couldn't be tightened really tight. So I took some thin pieces off hard but thin plastic from a case or project box or something and simply super glued them to the top of the fan. The plastic pieces rest on the top of the R9000s top cover and keep the fan from sliding down. They only overlap the R9000 top cover by a quarter inch
I can't even count how many years this fan has been running and had the bearings not dried out the other week, I really didn't know if it was running unless I worked my hand in back of the R9000 and feel for airflow

Does it help prolong the life of my R9000? I don't have a clue. But knowing that heat is one of the killers of electronics amongst other things, it sure can't hurt.

I'd take a picture but getting the R9000 pulled out for maintenance is a job in itself.

Thanks for this extensive info. Any photo whatsoever would help . . .

My 2 cents. It's always better to pull heat away from a heat sink. PC fans and PSU's don't blow air over their sinks for a reason.
I would guess the 9500 would run the same temp. all the time when switched on. But in a lot of devices I've found that the thermally controlled, internal heat sensor/speed controller fans are pretty slick. Very quiet under low loads. But really wheel when the heat goes on.

I picked up my IC-R9000 last June. It includes a little bit noisy fan (not so much). The previous owner told me that the fan was installed by ICOM due to the fact that the radio was originally intended for the australian market (no idea why the radio was sold in Europe).
He bought the radio here in Italy around the year 2000, now he sold it to me and I'm very happy because it is like new. Never opened the box, so I don't know which fan is running in it. During long operations the rear heatsink becomes hot, but I'm able to take my hand on it without any problem. So it is all OK for me.
