Thermaltake BigTyp VP and MaxOrb EX CPU Coolers
Test results (stock/reference assemblies)
First of all, let's see how BigTyp VP and MaxOrb EX perform in the quietest mode (conditionally noiseless domain) in comparison with several competitors of the same class.

Chart 2. Thermal resistance (conditionally noiseless domain)
As you can see, BigTyp VP does not demonstrate consoling thermal results. It lags behind the leading coolers catastrophically, the gap reaches 20°C (or 0.13 C/W in physical terms): extremely dense fin steps assert themselves all the way, clamping down on any attempts of the stock fan to blow them through. Although assemblies with the reference Minebea fan show some technical progress in the BigTyp VP image (which has to do with the "dry" connection between pipes and fins instead of feeble thermal glue in Big Typhoon), the stock Everflow fan demonstrates its inability to operate at extremely low speed. It makes the deficit of cooling capacity even worse. On the contrary, MaxOrb EX puts up vigorous and coordinated performance -- its results get close to Scythe Ninja Plus Rev.B (which is designed for low-pressure air flows) and Thermalright Ultra-120 eXtreme. That is the cooler demonstrates its results owing to its skills, not to its technical parameters (heat exchange surface area of MaxOrb EX is twice as small as in BigTyp VP).
Now let's have a look at the situation in the low-noise domain, where we selected not only High-End products, but also several Mid-End products -- Cooler Master Hyper TX2, GlacialTech Igloo 5750 PWM, and Scythe Mine Rev. B.

Chart 4. Thermal resistance (low-noise domain)
Well, the situation remains the same on the qualitative level -- the stock configuration of BigTyp VP stops short in the group of outsiders, being outperformed not only by High-End coolers, but also by Mid-End products -- GlacialTech Igloo 5750 PWM and Scythe Mine Rev. B. Alas, even in case of similar flow characteristics of our fans (the on-board Everflow fan and the reference Minebea) the static pressure still does not agree well with hydraulics of BigTyp VP. So it cannot contribute to more or less serious ventilation of the heat sink to reach optimal heat release coefficients. At the same time, MaxOrb EX retains its competitive positions again -- it tries to keep up with state-of-the-art coolers and demonstrates decent thermal efficiency.
Now let's have a look at the results demonstrated in the ergonomic domain (noise reference mark -- 31-32 dBA).

Chart 6. Thermal resistance (ergonomic domain)
Results are smoother here -- BigTyp VP starts to use its advanced design to close the thermal gap to MaxOrb EX. It launches an offensive to such rivals as Cooler Master Hyper 212, Scythe Andy Samurai Master, Scythe Ninja Plus Rev.B, and Zalman CNPS9700 NT. Nevertheless, the heights inhabited by High-End coolers (Thermalright Ultra-120 eXtreme and Noctua NH-U12P) are still objectively out of reach. Results of MaxOrb EX in this mode do not look that convincing either: its efficiency does not progress as pronouncedly as in BigTyp VP; Mid-End coolers do not loosen the grip either (GlacialTech Igloo 5750 PWM and Scythe Mine Rev. B). They demonstrate practically equal results.
