Re: FT-991A Fan mod
I no longer own my 991A, but a quick Google and brief read of some QRZ forum discussions on this, I found the link to a UK supplier of the Sunon fan outlined in the modification.

The Sunon fan is mentioned at the bottom of page 1. However, there's no reason why you can't fit another make. Key is to ensure the airflow is good enough, the fan has a lower noise level and it doesn't draw more current than the factory fitted Panasonic.
Good luck...

Thanks for that one.
I did find it there but on back order no idea how long it would take to get one from them.

Re: FT-991A Fan mod
You're welcome
Let me know how you get on. Fan noise can drive you potty.
I had to do the same to a power supply that had a built-in jet turbine for a cooling fan!

I found this one last night and looks to be about the same as the recommended Sunon i think.
Only just noticed it doesn't show the link i posted but this is the one i found on amazon.

At 27dba, it's mightily quiet. Slide bearing too, so it should be reliable.

Re: FT-991A Fan mod
That is the one yes.
When i put the link in it didn't show in the post.
I bought one so we will see and if it is ok might just buy another as a spare.
Funny thing is they where £7 when i bought it soon put the price up.

Re: FT-991A Fan mod
Got the fan and only tested it on 12v and boy does it move some air but that is flat out.
Going to give it a go but in a day or so got man flu at the moment lol.

Re: FT-991A Fan mod
I had a look at the noise blocker fan but the specs where way out.
Wattage is 2.8 but radio fan is 1.5?.
CFM is too low on them as well.
Thanks anyway might use them in a power supply sometime.
