Clever bit of work/workmanship... well executed.
Computer gamer in your spare time?
Does seem as a substantial: effort /expense /parts to eliminate a Simple heat sink though.

Having the drains separated by distance will only slow down the electrolysis, not prevent it. How do you know it will not be a problem? A thin layer of corrosion on the positive drain may reduce thermal conductivity.
Bcmbob did a nice job with his water cooled F5 too.

We are all gonna die , and so what , do we stop to live ......
Passions are priceless ......

Could you encase the entire pcb and components in water? If I remember back in to day (80s, maybe early 90s), Cray supercomputers did something like that, but some other liquid.
Using pure water , components have to be distant from each other , at least 10 cm .
may be with some other fluid , who knwo's ;-)

CPU coolers also use lot of fins in the cooler block to make it more effective.
But if it is ok this way, then it is ok. You could slow down the pump even more, make it even more silent.
You can google submerged PC and see how well electronics can work in distilled water or oil.

Electronics in audio behave differently , i am not sure that immerging the all amp in pure water will works , not sure at all ;-)

In what way does it behave differently? Frequency is lot less, voltage might be higher, but leg gaps are also lot higher. In what way is it different?
Why don't use mineral oil bath ?
Cheap, easy and efficient.

put your amp in the water , and you'll see ( or hear !!) 😀
mineral oil is a bad heat conductor compared to water , it may works great for other kind of cooling , for higher temperature ;-)
here we work at 35°c to 40 °c , and we need the fuild to take the much heat and the faster as possible , pure water do the job , so why worry ;-)

It is worse, but still can be used and many use it. Alu is also worse conduction than copper, but we still use it. PC also likes to keep cpu under 60-70°c, transistors also like to run around that temp. Not 40. I'm not saying water is not better. Just sad that oil can also be used. While single transistors usually have to handle max 50W, cpu with nearly the same size sometimes have to handle 200+W. So you need to take case CPUs lot better.
By the way most of the time not pure water is used, but with some additions so water doesn't get green. Especially when it is contacting air. Like submerge.
Anything that is about cooling was already done with PCs. So anything that works there will work with amps also.

did some mods today , less water flow and a bit more fan speed , reduice the working température , it's now 17 ° c over room temp , cool ;-)

Happy new year to all of you guy's , I wish you all the best 😉
the amp still working very good so far 😉
