[QUOTE="John Roberts, post: 88473, member: 126"] Re: PSA: Blow it out yer amps! Passive cooling is still popular for install amps where fan reliability is a concern, not to mention that forced air cooling draws dirt and dust into the amp. There are practical limits to how much power you can make without a fan, while the modern class D technology promises to increase that, while low power generally remains low tech. This low power/low tech may be changing. I use a small class D amplifier SMD IC, about the size of a wood tick, who hasn't eaten lately. Great for low voltage battery operation. So rack mount amps without fans could happen. Studios and consumer markets would appreciate the lower noise. JR [/QUOTE]
