Hi I have a question about the RX-V3800 and it's temperature/ventilation.

I've recently upgraded from a Yamaha RX-V2300 to the 3800 and the unit runs considerably hotter than the 2300 did. The manual states that it requires 30 cm on top and 20cm on each side of the unit for ventilation.

The old 2300 manual says the same thing but i ran the 2300 for 6 years in a space with about 7 inches of open space above it and about an inch or so on each side. It's in a cabinet and while this isn't an enclosed space it's not near the 20cm on each side like the manual states.

My question is whether or not it's safe to place the 3800 in the same space even though it runs a little hotter? There's plenty of air circulation on the top of the unit but the sides dont have 20cm since its in a wall unit. Will this be ok? Thanks in advance for any help!
