Onkyo TX-82 cooling fan.

Just like to post a fan solution for these induction cooled receivers. I've got two laid out similar to this.. a tx-16 and a JVC both with stk's that are both stk models and the main board in front of the outputs on both over heated.

This TX is equally hot. Cover off? Cool as can be.. cover on? internals on the output side ramps up to near 90F in 68 deg room temp.

The mock up I made is metal brackets out of thin shielding metal, easily pliable many times to get the shape for the stand off (1/2 or so here) Aluminum pie plate from the grocery would do equally well. When I look back with all the bending I did I could have used some super glue, some plastic spacers and nylon tie wraps!

Motor is cpu cooler with a 6vdc rat putting out a little too much for the 0.7a motor. could run two but 4.5v will run it even slower and still kick butt. as is it's quiet though so may leave it as it's cooling well.

Had to rewire the non switched outlet to switched with a couple wires.. the tx-84 has a switched relay in the circuit and a couple fuses.. but this is harmless.. not even sure I needed the ferrite on the rat.

Thanks Jegor.

I thought of tapping off somewhere but this board is pretty tight.

This rat fix is a no worry for someone with little experience without the hassle of rigging up some kind of mounting brackets. Good for any box with some room in it.

Good amps usually by brand just they cool poorly.. worth a pick up if you see one that looks clean and works.

Nice mod.

I just lay the fan on top of the unit....

Well, if you add the area of the grid on the top cover that is open compared to the area that is steel, on most amps, there isn't enough open space to draw or push air if a low voltage (i.e. 4" cooling) fan is laid on top.

BTW if you have the room inside one can hang a fan vertically, too.
