Review on 💧 G1/4 Inner Thread CPU Water Pump, DC 12V: Ultra-Quiet & Efficient Cooling System for PC 500L/H - Noiseless & Reliable by Michael Wilson

Bought 3 months ago. Yes, it's a bit noisy when you first turn it on, but once all the AIR is out of the pump, it quiets down. After I deflated the system, it worked like a charm. I use it as a test device. It is used in a home built thermoelectric freezer where temperatures regularly drop below 32°F. And I have another similar pump from another supplier and they both work with no problems. Remember that you must not let these run empty
