I purchased this AC Infinity fan about eight months ago, and its performance is astounding. I've used it non stop, 24 hours a day, 365 days a year, to cool the IP router in my home's garage. It has been running continuously for eight months, and it's still going strong! I can't praise its durability enough.

I bought three of these fans to cool tube amplifiers. They are dead quiet and do a great job dissipating heat. Keeping heat from building up inside the amp extends tube life. Affordable investment.
