I believe ambient temp is always the base line; therefore the word "climbing" to ambient temp doesn't sound right :)

Glad to see a fan mounted on water block :D

must say their kit seems quite good, indeed, i was quite puzzled when i read that sentence about climbing too :)
the whole idea of providing mosfet cooling is quite good i think, though if you have good airflow through your case and heatsinks on the mosfets you should be fine too. they could have addes some fins to the waterblock though, with the fan running above :d
