You can see here, as Marci (Thermochill's kinda-sorta rep back then) says, they switched over to ROHS stuff several years ago. ALthough to be specific, the water-solubility of the flux is a different factor, and doesn't necessarily corelate to ROHS.

They MAY do so, but there's no hard rule enforcing it... merely rules enforcing the use of older fluxes with components that do not comply with RoHS. |
Now, Thermochill's miserable stock situation is (and always has been) another issue altogether. watercooling.co.uk and chilledpc are both showing them in stock, for that's worth.
