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 –
