This one has 2-pin socket, GND+5V only and rock3 has 3 pins (+PWM) and much smaller connector. This won’t fit including screw mount holes designed to other board than rock3A 
edit: on first photos it seems that fan header is same as on rock3a (3pin) so I assumed that there should be something similar to rock3a. Of course if its that white header near emmc. If this is changed to 2pin then any 5v fan could be used if You can attach it there. This one won’t fit - it has different screws location.
Introduce ROCK 5B - ARM Desktop level SBC
On the other end they have super fitted nvme extension board to mount it. It’s super slim and much better than something like on rock pis. Of course it won’t fit factory case anymore but it’s not problem for everybody. For me nvme slot speed is disappointing - it’s only 1x lane 
and according to specs for vim4 it will still have 1x lane
Upgrade RADXA boards 3B and 5B with active heat management.
Works as well with e.g. Starfive VisionFive SBC
Doesn’t say its for the Rock3A but that is what is in the shop and what Radxa are providing not sure if the pre-release images are exact to what we might get as a production release.
@jack
True, I just assumed that there have to be something like for Rock3A because from release photos it’s probably the same 3P connector. That may be changed on final product as @jack said 
For starfive fan also mounting holes are specific, so I don’t think this would be good choice.
There are some fans for RBpi with 5V + PWM pins, they can be controlled from GPIO: https://wiki.52pi.com/index.php?title=F-0012
To be honest I don’t see the point in PWM but guess for us in different climes or load it give ability to set different speeds.
You can just stick a 12v on 5v or a 5v on 3.3 and both silent and loads of air flow.
Yeah I agree. I also purchased a Rpi4 back in 2019 and I have been extremely impressed with the amount of support it gets, I mean my vim3 can’t do stuff(run 64 bit android apps) that the Rpi4 can do with much less cpu/gpu juice! This is why I’m so excited about what Rockchip is doing with the rk3588 soc!
Yeah Raspberry make 100% profit on all there boards and think it was £10M last year and there is no comparison really to a relatively small outfit like Khadas.
The Radxa Zero2 is out soon which also is an Amlogic A311D which also complements the previous Zero Amlogic chip so you can counter revenue if you get a big enough herd so maybe Khadas will also benefit.
Rockchip is throwing some weight behind Android also Linux but like all many of these boards are fresh and part of a development and support cycle based on number of users and funds.
If you don’t get the herd (numbers) or enough funds without a lot of manufacturer SoC support things can be very slow or even freeze.
The Radxa Fan 4012 is 2P and currently work with pico-itx boards only(3B/5B/VisionFive), not the pi form factor because of the size limitation.
Is there any ETA on the board? Even a rough estimate?

I’m wondering the same thing. A popular youtuber made two videos featuring the rk3588 soc and oh my! I can’t wait the the single board computer powered by this amazing soc
@radxa, I haven’t found the answer in the thread. Do you know if the penta hat available for the rock 4 will be compatible with the rock 5?
If i may ask. Is that 100% profit a typo or it was meant as a sarcasm? Can’t figure that out definitively as english is not my mother tongue. Thank you in advance.
Nope but incorrectly worded really I read somewhere the markup is about 100% for raspberry on build cost to actual sale when they have packaged and delivered I think they make about 10% on each board.
They have huge sales that are massively automated and that is how they employ so many engineers and staff whilst still providing such low cost boards.
You can check there accounts but doesn’t break down to actual build cost just gross cost which they include a lot of overheads but a Pi in build cost is prob more than half its final sale value.

Now i think i can understand your point better. Thank you very much for the clarification.
If Radax allow, in order to help none technical people appreciate the RK3588 performance abilities. Here are real world uses.

Does the board have 2x CSI connectors as mentioned here https://linuxgizmos.com/rock-5-sbc-features-octa-core-rk3588-16gb-ram-and-triple-displays/
Or is it one MIPI-CSI and one MIPI-DSI?
It’s 1x MIPI CSI 4 lanes that can be split into two 2-lanes MIPI CSI.
Will it be possible to do 4K editing on this board?
Picked up a DJI drone the other day but noticed my MBP did not have the horsepower to even play the video video content H265(mov) or H264(mp4), even less for editing.
If yes, 16Gb ram i recomended(or 8Gb will perform equal)?
Page 10: H.265 HEVC/MVC Main10 L6.1 : 8K@60fps (7680x4320)
These days i believe almost all fairly new SOCs support hardwareacceleration when it comes to decoding H.265 and such.

In case anyone is wondering about RK3588S real world performance. Eta Prime just posted a YouTube video testing beta Android 12 ( no Google Play ) gaming on a Firefly SBC.
