Just finished upgrading the cooling to a chiller and custom indicator with external temp sensor, the chiller/ air pump and ventilation are in another room adjacent so it was difficult to keep tabs on water temp levels at a glance,
For those interested the corner pipes are from a pc cooling set on amazon: https://www.amazon.co.uk/dp/B07F8VM71J
and the temp gauge and spinning flow indicator are there too:
