How about the use of cpu collers of a water type.

[Triodethom]

Any thoughts on using some of the water coolers that are made for cpu they are designed to cool 125 watt cpu . Given there are fans but in a box their not that loud to me if the correct fan is chosen. What are your thoughts as to the effectiveness of this method ?

Sorry that's Coolers

There are a couple guys working on that basic idea in the Pass forum, it seems like a great idea for the bigger dissipation amps.

Given current price of them a classic krell box class a amp looks doable with low noise fans.

They're called waterblocks, and they can take quite a bit of heat away, but you also need to dissipate it again, lots of noisy fans, preferably outside.

Its been done for donkeys years but I quit using it purely because of the high maintenance and risk associated with topping it up and continuiously checking it for leaks.

It is also costly, a heatsink shys in comparison to the cost of a large watercooling system including pump, waterblock, radiators, fans, twin variable power supply for fans and pump...

Would be good if you want to make a small amp, if your limited on space but also have a window nearby.

There are also passive colum radiators for watercooling setups, maybe two of them would be silent enough for you to enjoy the amp fully.

That full blown system is over the top from what I was thinking . 2 self contained water coolers like corsair makes as does a dozen others . Cost at about 70 dollars us . There are some very quiet fans that move a lot of air have them in my 6core and the new 8core does a great job of cooling .

don't me fooled into thinking that watercooling magically absorbs all of the heat and just makes it disappear, that water does evaporate and there is where your heat is going, into the air, aka a sauna.

If you need better cooling it is infinitley more efficient to simply use a very large 140-200mm fan ontop of the heatsinks, large fan = more airflow = lower speed = less noise = undervolt it if need be = silence

I see the use of fans a good way of improving the heat sinks effectiveness . The water cooler I spoke of are a closed loop systems like an automotive cooling system . Your chose of fan is far simpler and very reliable . For that matter in the distant past I have built chimneys as the quietest way of increasing air speed across passive heat sinks.

If your liquid cooled pc does this regular, you got it wrong.

Cougar Vortex 120mm fans run under volted, make a 'Laptop' type cool pad, fans under fins, job done with old school chunks of finned alloy.

I tried using a water cooling system for a Zen V4 variant and used a hydor brushless PC cooling circulator hooked up to a small washroom radiator. It was extremely effective at removing heat from the heat sink at the back of the amp but although the pump was quiet it wasn't silent; probably noisier than cooling fans would be. Sort of defeats the object of high end audio. The other problem was that after several months the circulator would silt up with black copper oxide sludge and would stall. This caused overheating with some spectacular blow-outs.

It was a great talking point! but I eventually had to replace the cooling system with the normal massive heat sinks.
