OK, seriously now...
I've been reading a lot of Reserator bashing and "opinions" in this thread so thought I would add my $.02 worth. I have been using a Reserator for three weeks.
XP-2400 @ 2,000 Mhz, 1.65 Vcore
Amb air = 24 C
Ave water = 33/37 C
CPU = 39/45 C
idle/load
CPU temp measured with a calibrated thermocouple on core
Open loop system flow ~ 28 GPH
with external E-1048 ~ 58 GPH
Of course this isn't a high-end, high-performance cooling system. Zalman specifically designed it as a fan-less water-cooling system to be
silent.
"Let’s face it – a knowledgeable DIY type could put together a very quiet water-cooled system (or air-cooled for that matter
that would provide as good or better performance for less money than the Reserator I – but it wouldn’t be silent. And you have to remember, the Zalman Reserator was not designed for, nor is it being marketed to the DIY enthusiast seeking a high-performance cooling solution."
This data was generated with a thermal die simulator...
IMHO the Reserator is a unique cooling solution - for those with modest cooling needs who want an easy to install kit that is silent and looks cool!
