I thought I read somewhere that the newer class D modules radiate alot of thier heat toward the bottom of the board. Would you say yours exhibit that characteristic?I’ve let them run for three 4 hr sessions playing 5.1 pretty loud, mostly unattended and they get quite hot. On one warmer day they both hit 46 deg C after about 3hrs (114F) on the top lids
I’m going to retro fit thermal pads between SMPS heat sinks and chassis walls and chassis bottom to see if I can get the temp down a few degrees. Keeping lower temp will prolong life.
Maybe I’ll need a couple of small Hifi rack fans (silent).
Most of the heat is via the SMPS and Amplifier boards which have large heat sinks at bottom.Next time I do a test run in I’ll take temperature readings on all 4 sides,top and bottom. This will be prior to adding any thermal pads.I thought I read somewhere that the newer class D modules radiate alot of thier heat toward the bottom of the board.

Thanks. I was looking at these for my amps and was wondering about their noise level. Is your AVR enclosed or on an open shelf?I had them spinning away on high and didn't notice them even during quiet parts of the movie (I sit about 3 metres from them)
Mine's semi-open shelf with a fair amount of breathing room above it. The whole front of the unit is open and there are gaps at the back for all of the wiring which facilitates a decent amount of airflow - looks pretty similar to yours. Here's a pic:Thanks.

My chassis only have small air slots but I’m sure they’d help.
Wow. I remember being impressed when Burning Shed could get an order to Australia in 5 days, but this takes the cake.I ordered some 310mm x 310mm Graphite Thermal Pads (0.13mm thick) rated at 20 degC/mK heat conductivity from Digi-Key in Minnesota on Tuesday morning at 8:00am MEL time. It just arrived at 11:00am on Thursday morning !!! Just 2 days and 3hrs from time of order to me in Melbourne, Australia via UPS (free as my order was over $50 AUD.
Thatt’s got be a record for delivery time?
