Martinm210: that's why i want to see real test with high load pumps included, as by specs AA5 shouldn't be handling D5 pumps, but read this thread through .. IIRC there was one guy with AA5+LC block regulating even two D5, with little juice left for few fans. Just that pumps use fixed amount of power at preset speeds, so maybe for nice charts (W on channel/AA temps) some artificial regulatable load maybe of better use to get full range of AA5 capabilities even below and above what pumps provide (and what specs tell ).
BTW, imho one rather important point of article linked above is how close is active air cooling vs lc block for AA5.
