I had to replace the fan on a Kona 3G several years ago. Didn't have an issue with the fan wires, but the thermal adhesive on the fan was a nightmare! I thought I was going to rip the chip right off the board, even after the heat gun assist. Thankfully it survived and is still running today.
24.24 - this is not VGA out, it's RS422 for VTR remote control, so if you'd like to have TC recorded from the videotape you have to connect your VTR to this socket as well. DVCPROs, betacams, very hi-end SVHS decks and, i presume, HDCAMs, all of them carry this interface installed by default. By doing that, you will have the possibility to control the deck from AJA Control Room as well as the TC will appear in the captured file. Nice feature. I use it by default when digitizing my DVCPRO tapes.
I had to laugh when a full card was delivered instead of just the fan :-D That power connector does look easy to disconnect from, but breaking off the pcb is a pig. Great you have found a capacitor to tack red and black wires to, easy fix :-D. I tend to blame the psu in p.c systems, the psu caps always get the brunt of the wear. I have used high grade low esr capacitors made by panasonic.
Lots of tricks to removing stuck on compound. I find the older AMD processors came with the worst stock compound for this and so have a bit of experience. Usually letting it heat up a bit (as in powering it on) and then using a twisting motion helps. But this isn't a processor you can get off eBay for a tenner. Maybe soaking with IPA would make the blade removal less tedious? No way you can get something less bespoke, something like a Noctua fan working on those cards? Also I was about to get very cross that the big PC at the 12 minute mark did NOT come via Son-Ex "Special Delivery!" but thankfully later in the video my need for that was filled. Great video as always.
Another thing to remove a heatsink you do it with a twisting motion and a little force and it pops right off ... as some one that does lots of electronics you should know all that !!!!
Maybe the fans just need some oil, a drop or two of 3 in one would be fine. Some fans have access to the bearing, usually hidden under a sticker. If they don't have easy access to the bearing you can sometimes carefully take it apart and oil it that way.
Good to see this card operating as it should. Replacing unusual fan types is a pain I've had to deal with! Slightly off topic question if I may - Have you found many problems with Windows 11 and the hardware you use, or was the transition from 10 fairly seamless?
That's useful, so it can run pretty hot. Hopefully the lower power fan will suffice, when they arrive. I could use a temperature sensor to get a very approximate feel for how hot it then gets.
Any advantage in particular of using a card over say USB 3 or thunderbolt blackmagic card? I guess if you were planning to capture several streams at once and it didn't overload your system and result in dropped frames, I guess that would be an advantage.
Personally I find the USB3 card much harder to use. It's fussy about which USB3 chip sets it will work with and is more likely to drop frames, go off line or just not work reliably. With a good fan, the Kona 4 just gets the job done every time.
It's not really intended for audio-only capture, this is a digital video capture device. You could get an audio to SDI embedder device perhaps, but that's a complex solution.
Because that takes time not only would he have to research the parts, then would have to wait for all of them to get in. In production environments having someone else do it makes sense and if they already have the parts on hand there is no waiting.
