It seems you want to use the official case. If so, measure it and check Noctua’s website for a compatible fan: https://www.noctua.at/en
The easiest option is to look on AliExpress:
compatible noctua fan product codes - [BPI-R4 PRO] Hardware assembly - #16 by rbtree
well, the bigger top fan is a hack 
but fits by chance
Thank you this is outstanding. I should have searched more before asking!
Thank you! Any news on compatible 5G modems? I realise no drivers have been loaded yet is that still the case?
I’m only interested in the official OpenWrt version from OpenWrt, not the Banana Pi one. I don’t even know which kernel the Banana Pi OpenWrt version uses.
→ Yes, I see the comments:
The Firmware Selector doesn’t include the R4 Pro yet: https://firmware-selector.openwrt.org
I’m not planning to buy the Pro within the next 6 months.
It looks like you’re still in your orientation phase.
If you have general questions, please open a new topic (because this is the case thread 
).
Yes, we have addressed this issue. You only need to update the corresponding image to use the 5G module.
Very good.
But as I said, I’m only interested in the official OpenWrt builds: https://firmware-selector.openwrt.org
As of now, there is only R4 and R4 Lite (Snapshot):
That said, I’m thankful for supporting OpenWrt developers 
with hardware!

Hi,
Is there any plan for selling a smaller version of this case for those who don’t need to add a wifi 7 card?
Thanks.

I already mentioned earlier — I was refused the sale of this case.
[email protected]: This case is new product, not on sell yet, and this case will use in the assembly kit, once it ready, we will let you know.
