Review on 💧 High-Efficiency 800L/H 8W 7V Water Cooling Pump Tank | 4 Meters Pump Head | LED Power Indicator | G1/4 Thread | Rapid Heat Dissipation CPU Cooling System (17cm-Black) by Todd Fernandez

The pump worked and the flow was good and stable but I found there was a small leak. It was found that the drilled hole for the bolt holding the pump assembly together had barely penetrated the threads of the outlet. This allowed coolant (under pressure) to flow from the outlet, through the screw and around all mating surfaces of the pump sections - it would have been a nice little pump that would fit my case at a decent price but I can't trust it. they will fix it soon. Be careful when drilling!
