ventilation for receiver needed

PoorSignal

Hello I installed a receiver in the storage/electronics closet, which is about 4'x3'. 8' ceiling. It is for audio in different rooms.

The receiver is Technics SA-DA8 and runs quite hot, the heat sink is facing the top and I checked the temperature is 170 in the heat sink inside and 130-140 in the ceiling. I only have 2 small speakers connected and volume at 11 o' clock for a few hours.

An oversight on my part because I put the receiver on a top shelf. I underestimated how much the heat would linger in the ceiling area. I am going to get a fan to plug into the back of the receiver so that it runs with the receiver. That should help with the circulation to take some cold air from below up to the top shelf.


However I think I would need to rig some slow ventilation fan into the attic. Any suggestions?

My friend, who has a similar situation, put a bathroom exhaust fan (low noise) in the closet ceiling which cools things enough (or actually stimulates enough air movement) to keep things at lower operating temps. It works great and you don't hear anything...Maybe that will work for you.

How much work are you willing to do?

You likely can install fans between your studs and drill holes to vent into the ceiling. You could manage 3 120mm fans.

You could drop conduit and have your fans in the attic.

But really the best idea is a bathroom fan, in conjunction with an amp fan.

I added a computer fan that blows across the top of the receiver it lowered my ceiling temperature to 95-100, over 30 degrees difference. I just plugged it into the back of the receiver. I guess that should do for now.

Running an open conduit from lower floors up to higher floors or an attic is usually against fire code regs, since it will bypass the fire blocks built into more recently built houses. By doing this, it would allow fire to travel through the various floors of a house faster, AND provide fresh air intake to help a fire breath and spread faster.

I wanted to do this by having the builder of my house run a conduit from my basement to my attic 3 stories up to make it easy to add more cables, etc later put the building inspector would not allow it and that was 20 years ago for this very reason. I could have added it afterwards myself but that would increase the danger for my family so I do it the old fashion way and have had to snake wire or run it inside the J channel of my vinyl siding to the attic.

I'll have to check into this.
For the moment I'll have to plead ignorance suspecting that
1) You're odd as you have a 3 story dwelling
2) If you do this, you might need a firestop (I think fiberglass counts)
3) You might be golden if you plug the hole (cap, spray foam with light oil so you can remove/replace the spray foam)
But I mainly thought it this not being an issue because generally speaking one/two family dwellings don't need firewalls.

But to be clear, you bought up a damned good issue that might be a code violation.
