Hi, I have PiB+ & Amp+ (18v 4 Amp DC power supply) which will play a variety of music about 8 hours a day into space about 20m x 20m x 4m using (at least) a pair of ceiling speakers 8 ohm (or perhaps 2 pairs in parallel i.e. 4 Ohm) at a "reasonable" volume (~80% on squeezebox controller & default settings for PiCorePlayer). As I type I'm playing Eric Clapton's Blues album at that level and note the Amp+ is getting "quite" warm !
Has anyone succeeded in fitting a heat-sink to the Hifi-Berry-Amp to manage the heat ?

HiFiBerry team Hi David,
that is not a problem. The chip has an internal protection. If it gets too hot, it automatically shuts down. As this does not happen here I would not change anything.
However, I wonder how you managed to get a reasonable volume at a room that big. We though about usual living rooms. What kind of speaker do you use?
Best regards

David Broster Hi Daniel, I shall eventually have 3 RasPiB+ & HiBAmp+ in same enclosure so I might use a small slow, quiet fan to push the generated heat away from the amp boards. The system isn't installed as yet, just testing. The speakers will be BluCube 650's http://www.amazon.co.uk/BluCube-CXCL-650-S-In-Ceiling-Speaker/dp/B0083GLSOU The total space is divided into 3 loosely connected areas in which I hope to deliver localised music (one area at a time) or synchronised sound (all areas together). I'm still considering a best strategy based on current testing, hence the question about heat sinks.

robert culpepper I've had issues with the heat. Our RPI and Hifiberry amp are in a location that tends to be hot, like 95F. Left to it's own devices it will shut down. I bought a couple small heatsinks and a small 5v fan (quarter sized) and it seems to have taken care of it. The heat sinks still get hot but I can hold my finger on it and count to 5.

HiFiBerry team While in hot locations, active cooling might be needed, in many places, the Pi4 even with the Amp will run fine without active cooling:
