Only the blower fans are dramatically different. Take a look:

CoolViva Pro features a blower with straight fan blades with variable rotation speed ranging between 700 and 1800rpm (±10%) that varies due to pulse-width modulation. According to the monitoring data, the maximum rotation speed of the CoolViva Pro blower is 1800rpm, which is completely compliant with the claimed technical specifications. SE model features a slightly larger (1mm bigger) and differently shaped blower with constant rotation speed of 1800rpm (±10%). However, its blades represent something between a turbine and a fan. Unfortunately, the manufacturer didn’t mention the airflow data in both cases, but I dare suppose that it will be higher by CoolViva Pro SE in case of identical fan rotation speeds. Moreover, the monitoring data also reported that the blower rotation speed exceeded the claimed deviation of ±10% claimed in the specifications and reached 2050rpm.

CoolViva Pro blower is manufactured by Delta Electronics (BFB1012L model), while the SE version features a turbine from a not very well-known Taiwanese Talent Top Ltd. Company (DT1275LSAV model). It is very interesting that despite more aggressive blade design, the level of generated noise by the SE cooler is claimed to be 1dBA lower than that of CoolViva Pro (19dBA against 20dBA). Among the drawbacks of the new solution we should definitely point out a less long-lasting slide bearing that they used this time, while CoolViva Pro has two frictionless bearings. The CoolViva Pro SE also has no PWM support.

The copper cooler base of both solutions is very nicely finished and is equally even:

Also, I have to point out that the new CoolViva Pro SE is 30g lighter than the predecessor.
