My 8Kg water cooling 75W Class A Mono block

Simon62 · 3rd February 2012, 03:36 PM

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.

liquidly Fugly!

what's amount of fan noise ?

Simon62 · 3rd February 2012, 03:57 PM

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

I'm still waiting for the pictures to load, but it sounds great!

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).

Simon -- that really is cool

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
