I wanted to use the heat plate so the HSF would have a solid base. With it directly on top of the die I was afraid that the surface area would be too small and the HSF might move. If you see in the picture its really close to a lot of solder points.
For now I have it connected to CN2 and always on. The next step would be to use pwm for fan control. I think it's currently at 4800rpm.

Lolol 90c.. Watch my post and i suggest you go remove that heatspreader metal thing that came with panda https://www.facebook.com/groups/LattePa ... 004883916/ .. That useless thermal pad inbetween the thermal spreader is the cause of your problems. Mine is at 30c and highest thermal degree is at 50c running at 1800mhz on stress test.

we have had some luck with these, theyre also nice and low profile
https://item.taobao.com/item.htm?spm=a1 ... o=pcqq.c2c
i have also added this link to the resource list
unfortunately theyre not low profile enough to fit comfortably in the case, unless you hack a section out of it. we are working on a redesign of the case to accomodate for this.
before we got these i basically just had my engineering prototype unit stood off the ground on some m3 screws. i then got a 50mm 5v fan connected to cn2 header pins blowing on the underside, where the cpu is located. the fan is mounted on one of these "leg" screws. not exactly an elegant solution, but its been left on day and night and hasnt died yet. the fan actually stays on as long as power is connected, even if the board hasnt booted!
cheers.

we have been using these
https://item.taobao.com/item.htm?spm=a1 ... o=pcqq.c2c
will work on cn2 headers, although bear in mind that as long as power is connected the fan will be on, even if your panda is off!
also bear in mind the fan will be fixed speed and does not have a signal input
if someone has the time and inclination you could probably create an arduino sketch to address this...
cheers!

the fan works very nice, and keep the system nice cool. So that you can operate at full load with out to clock down the cpu.
With the plywood you can cut out the plywood to get space for the fan.
The Feeds in the corner will give the needed space...

Hi, I have installed a similar but a little smaller heatsink with an attached fan (5 Volt attached to the CN2 connector) using double sided adhesive thermal conducting tape to the metal housing on the bottom side of the Lattepanda where the CPU is installed under.
Fotos of it I have posted on the german Lattepanda forum. Here is a direct link to the pictures:
https://www.einplatinencomputer.net/Att ... -oben-jpg/
The fan i bought at the german conrad.de electronic component company:
https://www.conrad.de/de/axialluefter-5 ... 16709.html
At conrad-electronic.co.uk a similar heatsink-cooler is available (I am not sure if the fan is driven by 5 Volts though):
http://www.conrad-electronic.co.uk/ce/e ... ionarea=01
The installed heatsink/fan keeps my Lattepanda always at reasonable temperatures (<60°C)

they have been working pretty well. as described in previous posts, remove the heat spreader from the underside of the board and use some thermal tape (we have used 3M) to stick it on. runs nice and quiet too.
I have added a link to the fan in the resources list and I will make this topic a sticky so others can see it immediately and i dont have to keep repeating this!!!
cheers.
