Sure, as heat is electronics' bane I focus on keeping my Class A & AB amps cool. None are in "gear closets" or hidden, enclosed in furniture. I might add I've no doubt each one's longevity, as of this writing >20yrs, has been prolonged through years using laptop coolers. Point remains, and I'm asking others, why pay 3,4x and more for dedicated electronic multi-fan units when all that might be needed -again for longevity- is a simple $20-25 laptop cooler? Appreciate your input, ElectronicVices. Thanks!
