That's a great product and looks cool too, especially the T9 model, a little pricy though but I guess it's worth it.
I used to use a computer fan on top of my previous receiver (onkyo) and it really worked great, but since I got this Denon, it runs cooler compared to the onkyo even though it's more power driven.
Thanks for sharing the info.
Indeed, for a system thats upwards of 1lac then the t9 makes sense, else even the smaller sibling the s9 https://www.amazon.com/dp/B01LVUWOBX?psc=1 will work.
another good thing is that you can stack another component on top of it. so heat does not transfer from the lower component to the one directly above it.
