Nvidia Shield 2019 Tube "Airflow" case

The Tube Shield - or as I call it the Sausage TV - is an interesting design. The CPU has a heat sink and there is a fan inside the tube that supposedly, should suck air into the tube through the heat sink and exhaust it ... to nowhere. It's unable to push the hot air out of the case because the PSU of the device is in the way. Brilliant design I have to say.

If you use the device for a couple of hours it's fine, but as it slowly overheats (the whole case will be though the device has a ton of air behind my TV, it can't), the fan starts to spin at 100% creating an annoying whining noise. Even tho the device has a ton of air behind my TV it's unable to keep itself cool.

The point of this mod is to let more air into the device and provide a way to exhaust the hot air, keeping the device cooler, so the fan doesn't have to push hard.

I pushed the device to its limits for 6 hours and the fan didn't make any audible noise. The area around the new intake is noticeably cooler than the rest of the device. The whole case still can be warm, but the noise level is 0 or really low.

I use the Tube on Max Performance with Quite fan settings.

• the included *.stl is different from the one on the pictures
• it has smaller "aligning pins": on my original print, the whole Shield slid into the case, but got stuck at the "aligning pins" (those small things inside the case). I hope with this change it will slide through the case without any problems.

Raft is recommended, depending on your confidence.
