Я на своих аквариумах (60 и 75л) использую БП от антенн (большие такие решетки со сменными усилителями), у этих БП есть регуляторы напряжения, очень удобно регулировать обороты кулера. У меня на обоих стоит по одному 80 мм кулеру, экспериментальным путем подобрал с помощью регулятора скорость вращения, она получилась значительно ниже номинальной, поэтому жужжания практически не слышно, при этом все работает от таймера света, включается вместе с лампами, которые и есть основная причина высокой температуры в акве. Пробовал и 12 см кулер, но он даже на самых малых оборотах охлаждает сильно малый объем.

12 см кулер кушает в максимуме 120 мА, поэтому я думаю что один подобный БП потянет в идеале 2 кулера на средних оборотах, ну а так по одному на каждый. Экспериментировать надо. Нагрузить один БП по максимуму, и включить на прогон на сутуи, пощупать , послушать....
Если вскрыть его, заменить регулирующий маломощный транзистор на более мощный то и из этого можно миллиампер 300 выжать [acute] . Но это уже совсем иная история [smile]. Хотя можно еще к штатному транзистору примотать как нибудь пластиночку из алюминия или меди, чтоб типа теплоотвода было, тогда тоже можно побольше получить. Но все таки надо экспериментировать, щупать, слушать, нюхать... [crazy]
