How to reduce the depth of the cooling fan on the Edge-V

General Discussion

Hello to everyone.

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…

thanks.

Hello

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
