Thermal Testing My Water Cooled Raspberry Pi Cluster - Does Loop Order Matter?

In this video I'll be doing a thermal test on my water cooled Raspberry Pi cluster to see if the water cooling system is effective and to see if there is any significant temperature difference between the first and last nodes, since they're all connected in series. There were divided responses to my cluster build video, some suggesting that the loop order would cause the last Pi to overheat and others saying that the loop order makes no difference. Here's a link to the write-up of the test - https://www.the-diy-life.com/thermal-testing-my-water-cooled-raspberry-pi-cluster-does-loop-order-matter/ For the full write up of the cluster build, visit my blog - https://www.the-diy-life.com/building-a-water-cooled-raspberry-pi-4-cluster/ Thermal Camera Used For Testing - https://www.banggood.com/custlink/3DKhSOQV6B Display Used For Testing - https://amzn.to/2NHJlUn Cluster Components Purchase Links 8 x Raspberry Pi 4B (2GB Model Used) – https://amzn.to/3i0eYni TP-Link 16 Port Ethernet Switch – https://amzn.to/2Ldn9km Rav Power USB Charging Hub – https://amzn.to/2MNCSH3 HD Touchscreen Monitor - http://amzn.to/38ug1Zq Water Cooling Kit – http://bit.ly/3sfTAiO 8 x 30mm Cooling Blocks – http://bit.ly/38vZa8I 8 x Ethernet Patch Leads – https://amzn.to/2XPjfAS 8 x USB C Cables – https://amzn.to/35rOwOp 3m RGB LED Strip – https://amzn.to/3nyaPbt M3 Standoff Mount Kit – https://amzn.to/38u6Qs8 M3 Red Aluminium Standoffs - https://www.banggood.com/custlink/KKvd8SbbvU M3 Screw Kit – https://amzn.to/38wl63J 3mm MDF Board Approx. 600 x 600mm Note: Some of the above parts are affiliate links.
