How do you deal with component heat?

    @F1nut I agree, not very smart... even worse if it’s a turntable, it sits 2” above the amp but it’s enough to raise the temperature ~5celcius degreed. One fan running slow in between helps air circulation and dissipates the extra heat.

    I have to figure where to place the turntable, not sure how.

    @codycatalist oh man I wish, I could live with that if I wasn’t too OCD :)

    They sell wall mounted turntable shelves.

    I purchased an AC Infinity T9 to put on top of my marantz 7013. Both will be on the top shelf inside a closed media cabinet (glass door) with a large vent hole on the floor of the cabinet and vent slits through the top of the cabinet. Would you recommend adding an AC Infinity S9 in that bottom vent hole (already cut to fit the S9) to draw cold air in or is the T9 working alone enough? There will be a panny 820 BluRay player and a standard cable box on the bottom shelf. Both shelves aren't full depth so air can flow in front and behind. I was also considering building a hidden mount for a furnace filter under the cabinet to control dust but may be over doing it.

    Give it space. Mr John Curl gave me advice on biasing my HCA-1000A higher than Parasound did from production based on temperature. In my cabinet with 2 inches above the amp, it has burning hot. I have it sitting alone with several inches above and it is happy. I could probably bias even higher.

    space plus convection (heat rises, as they say), unless the designer/manufacturer packed too much stuff into too little volume -- cf. every HT receiver. ever. ;)

    I'm guessing active cooling negates the need for extra space for natural convection. My question was whether I need to actively draw in cool air into the cabinet or is an active exhaust with passive intake sufficient. Regardless, I picked up the AC Infinity S9 to act as an active intake. It can be connected/controlled by my existing T9's thermostats. I figure it's better safe than sorry. Also added air filters in front of the intake to control dust.
  • My Denon receiver was getting extremely hot to the point of frying eggs, until I bought this kit:

    https://www.amazon.com/gp/product/B011SY1XMK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

    Set the fans on the sides sucking out the air, or on top, or one of each. Figure out what works for your setup. Very versatile, and you can use on one or two pieces of equipment.

    They have their own power supply (unlike other fans that can plug into USB ports, which is really bad because fans/motors are notoriously bad on their initial power spikes - you wouldn't want that type of fan running on anything you care about!).

    Plug into one of the receiver's triggers, and they only run when it's on. Perfect. Quiet, and now my Denon is ice cold to the touch.

    If it ain't hot it ain't worth squat.

    ^^^ FWIW, the bulb (envelope) temperature of a 2A3 can run up to 200 degrees C (per the specs in the tube manuals for power output tubes -- and HV rectifiers). That said, yeah, heatsinks at 57-ish degrees C mean a lot of power being dissipated as heat :#

    As to efficiency -- yeah, probably. As I recall, that amp only draws about 100 watts (per a "Kill-A-Watt" meter) for 2 x 3.5 watts output at "hifi" levels of HD (less than 10%).

    Which really ain't bad at all ;)

    The amp would run cooler if it didn't have something sitting on it.
