I’m planning to buy the Khadas Edge-V Pro board that I will use to assemble a phone based on FreeBSD. Because I’m talking about a phone,I would keep a low profile. It means I want a depth of max 1.5 cm. Now,the Edge-V Pro + Heatsink + cooling fan is 10.42 mm.
But most of the depth is due to the thickness of the Heatsink + cooling fan. My intention is also to use a powerbank,the model TNTOR 10.000 mah,is 1 cm.
The overall depth is more than 2 cm. My phone will looks like a brick. I don’t like it.
I would like to know if I can use a different kind of cooling fan. For example,on my Radxa zero 3W,I’ve bought this one :
Taking in consideration that the Radxa Zero 3W heats up a lot, reaching very high temperatures,I suppose that kind of skin can be also used for the Khadas Edge-V ?
Is there something like that that I can buy to use ? It will allow to save at least 0.5 mm of depth.
Forgot to say that on the Edge-V I will remove almost every port,except the usb-c and the hdmi connector…
The fixation of the heatsink and heat dissipation performance cannot be guaranteed if use this heatsink. The best solution is that re-develop a heatsink meeting the depth requirement, however based on a certain amount.
I noticed that you have bought one Radxa heatsink, so currently I suggest you check if the structure matches with Edge-V and test the heat dissipation effect (hard to confirm according to the known information for us)
I think that producing this kind of product is a nice idea for you. I’m not an engineer,so I can’t create it from scratch. But I imagine that I could buy a product like that If I know some technical details,such as :
a) where should be placed the skin ? on top of the cpu is enough ? What are the dimensions of the cpu ? maybe I can buy 2 or more passive cooling fan like that of the radxa zero board and I will try to adapt them,trying to cover all the cpu area.
b) how much depth should be ?
c) can you tell me where I can get / download the dissipation test ? Is it a tool that should be launched on Linux ? (I doubt that it will work on FreeBSD) ; Did you post an useful video on youtube ?
d) I think that if you can help me with more attention,you will find a good dissipation skin to suggest me to buy in some shop
Have you ever tried using phase-change material (PCM) plus a heatsink? You could lay individual PCM pads on the CPU and other chips, then press a single heatsink down onto all of them. Get yourself a temperature probe, run a full-load stress test on the SBC, and watch the measured temps. Based on the results you can decide whether to stick with the plan or kill the power and scrap the idea.
This is just a personal brainstorm—totally unvalidated and potentially risky. Be extremely careful, careful, careful!
This YouTuber explained phase-change thermal pads and shared his experience installing one in his PC. In the comments, a viewer recommended Honeywell PTM7950 and suggested buying it from Amazon.
Here’s the Amazon link I found for you to check out:
Since I haven’t actually tested it myself, I can only share the general idea with you. The final choice will still depend on your judgment—hope that’s okay with you.
