I'm using a 40mm sink and fan. It brings idle temps down to the low 40c and after streaming 4k for awhile I'm getting mid 50c or low 60c, 62c was the max. Hopefully it will stay cool in the case we make while running unity too haha. Loving this SBC!

Here is my version.

IMO heat sinks and fans are mandatory. I made my own installation hardware and bought what I needed from eBay. Everything came from China except the PVC & misc hardware.

I made a video of the install that is located here:https://youtu.be/oSE7_Hd6vEs Nothing fancy here. All made at home with a Dremel and box store PVC shapes. A 3D printer would create these brackets with ease. I taxed the LattePanda by running a high definition stream off of YouTube with W10 and never saw a Temp above 42C (using Speccy). Most of the time the core temperatures were in the low 30C range. ( House is at 18C.)

I'm now running Linuxium Ubuntu 17.04A2 and the heat sinks are cool to the touch. Linux seems to be much less taxing on the processor. Since this is a developmental release running on a new Linux kernel, I can't download CPU monitoring software yet. Everything works but Bluetooth.

Best Regards,
Ed

I have uploaded a simple lasercut jig to out GitHub. This jig lets you stick a fan underneath your LattePanda so it has air cooling the underside. Use it with some PCB standoffs. I regularly use this with my LattePanda.

The file is called stand.dxf. It is designed for a 60mm fan (I had a bunch lying around) but you can always edit the design for something else. This was designed using AutoCAD. If you would like to 3D print it you could also extrude it upwards around 5mm. I hope this helps someone!

I am interested in this as well, I have the DFrobots fan which connects to the CT2 pins and works great but the fan still runs when you power down windows.

For cooling my LattePanda I use a 30x30mm aluminium heatsink plugged to the backplate, a mini cooper heatsinks for the RAM and eMMC and a blower type fan.

To control the fan I made a mod for Open Hardware Monitor:

I you have a Relay or a NPN Transistor you can control the Fan by using this mod for Open Hardware Monitor (Power On when system start - Power Off when system shutdown - Activate by CPU temp)
