Thermal and Acoustic Performance

Well, here are the results:

CoolViva Pro SE has truly become much more efficient than the first revision. The performance improvement under peak workload reached 4ºC for GeForce 7900 GS and 3ºC for Radeon X1900 XT. This improvement results from the successfully modified turbine blower design that is also rotating 250rpm faster. Moreover, you can really feel this difference, because the airflow ousted from the system case by CoolViva Pro is hardly noticeable.

Radeon X1900 XT graphics card provides two additional results: ambient temperatures and voltage regulator temperature:

Of course, the situation improved here, too. And in case of voltage regulator temperature this improvement is pretty significant.
