Talking My 8Kg water cooling 75W Class A Mono block

I use normal computer water cooling tools to build this amp , not any special parts , everyone can find in market .

The result is very good. This amp running DC+/-38V ,Quiescent Current 2.2A, total consumption 180W, under the cooloing the 7*10*1CM copper heatsink temperature just 42℃ (room temp 18℃), so I think this way can make a very High Class A power amp then say goodbye to big monster aluminum case.

The Noctua 12cm fan noise about 20dB less , the dump noise little higher but acceptable.

Impressive build (Your equipment too....) !

I can`t spot anything which looks like an electrical water pump.
Do I understand this right that water circulation works through convection of the fan only?
How hot does this tiny (copper / brass ?) heatsink get?

Noctua fan, excellent choice for applications that require low-noise operation, expensive but worth the quality (have some in my PC running).

Apple G5 dedicated DDC pumps, transparent acrylic inlet and outlet for the modification parts installed directly in the pure copper heat exchanger

I believe this one is small and lightweight, and completely the highest degree, and integrated water-cooled amplifier
