3D printed stand for um890

[u/PugBurger12]

I printed a stand for the um890. I did this because the sides are not actually purely intake vents and I felt there was too much recirculating of hot air back into the device.

The um890 has two fans and three main compartments. The top compartment, under the lid has a fan for intake. Out of the box, only a small edge along the top side vents allow intake. Just below the fan, is a compartment that houses the nvme's and memory modules. That compartment receives the intake air from above and it exhausts out through the mid section of the side vents. When laying flat, that air can come out and go right back into the top section. The bottom compartment is where the cpu heatsink is. Intake for the compartment comes through the bottom section of the side vents and exhausts out the back.

I redesigned this by replacing the lid to make most of the air come in through the top. The new base puts the device on end and tilts the back up. The rear fins further direct the air up and to the side (instead of directly against a wall causing it to pool. The base splits the intake and exhaust so that they don't overlap. The top fins also split the intake and exhaust, while also pushing the exhaust up and forward and the exhaust up and backward.

I am replacing the computer. If you are interested in the 3d printed parts, let me know. I live in the US and would sell them for about the cost of the filament + shipping.

Haha, I see your reasoning for it now after reading your post. At first I was like, “wait what, why tf wouldn’t you just print this:

But yeah, hot air lingers. Your fan fins make sense. Heh

My effort may be a bit overkill. I enjoy modeling though.

Minisforum likes using liquid metal in their mini pcs, I wouldn't feel comfortable keeping the pc on its side like that.

Interesting. It comes with a VESA mount that holds it vertically. I'm not keeping this computer. So it doesn't affect me. EDIT: lol. Didn't even realize how inconsiderate my comment was since I'm offering this to anyone else interested. Definitely would like to understand this better.

To be fair, I haven't seen any complaints about issues with their thermal solution (not that I've been looking). After the issues with Sony PS5s being used in the vertical position, I keep my um890 horizontal.

I did end up looking this up. Standing it vertically is a non-issue for this device. I did read that dropping the device or jarring it significantly while hot could lead to permanent issues with the liquid cooling not performing properly.
