Not sure if 3 or 4 stars this article. On the one hand you get a lot of value for about 10โฌ. On the other hand, if you don't take the time to fix bugs, that's just a minor quality. First of all, the product comes with 3 blue spacers made of 3Mโข 9448A double-sided cloth tape. It's definitely *not* a thermal pad, just double-sided tape. Not totally useless, but a poor heat conductor making the cooling part of the case much worse than it should be. So you could use thermal paste if it wasn't for the second problem. Second, the 3 tabs for contacting 3 chips (CUP/GPU, memory and USB/Ethernet) are not properly designed. One CPU/GPU has good contact, the other two don't. So I used a file to reduce the height of the legs and make indentations for the USB and Micro HDMI ports (and added some Kapton tape for insulation) and I had good contact with the CPU/GPU and the USB /LAN chip, but the memory chip (which is average) still doesn't touch the aluminum pad. You can see what I did in the attached photos. And there is nothing you can do to fix this problem because CPU/GPU and USB/LAN prevent it from touching. I think I could try filing down the USB/LAN bar but the interface would get pretty bad. So now I use more thermal paste (bad idea) and will buy a real thermal pad just for the memory. So CPU/GPU and USB/LAN use paste and memory use thermal pad which can better fill the gap. In a way, the only really important part for cooling is the CPU/GPU, so in that sense it works well. , but it would require minimal attention to make it better, and the added cost of a real thermal pad instead of double-sided tape would help (that's a really bad compromise). So ok if you work a little just ok if you use it as it comes with thermal pad so if you use it as is and with insulating double sided tape
