Frequently Asked Questions (Lab Verified)
Are LCD screen pumps just a gimmick?
While LCD screens add aesthetic flair for displaying real-time CPU/GPU temperatures or GIFs, cooling performance depends entirely on the pump impeller and cold plate micro-fin density.
How long do modern AIO coolers typically last?
Modern closed-loop coolers with EPDM braided tubing and ceramic bearings typically operate reliably for 5 to 7 years before coolant permeation reduces efficiency.
Can a 360mm AIO tame an Intel Core i9 at 300W?
Yes. Top-tier coolers like the Lian Li Galahad II LCD and Arctic Liquid Freezer III keep a 300W load under 92°C, preventing thermal throttling.
