Test results

First of all, let's see how Lion Square and Triton 85 perform in the quietest mode (conditionally noiseless domain) in comparison with several competitors of the same class.

Chart 1. Temperature readings (CPU core temperature, conditionally noiseless domain)

Chart 2. Thermal resistance (conditionally noiseless domain)

As we can see, Lion Square demonstrates the best results in this mode, it achieves decent thermal results and actively competes with very serious rivals -- Scythe Mugen, Scythe Ninja Plus Rev.B, and Thermaltake MaxOrb EX. But it still fails to catch up with the leaders (Noctua NH-U12P and Thermalright Ultra-120 eXtreme). Performance of its impeller at 800 rpm is apparently insufficient for effective ventilation of two fin-stacks. Triton 85 also performs quite well. It goes almost on a par with Silent Knight II and outscores the stock assemblies of Big Typhoon coolers from Thermaltake.

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 3. Temperature readings (CPU core temperature, low-noise domain)

Chart 4. Thermal resistance (low-noise domain)

Lion Square shoots forward to the group of leaders here, being only slightly outperformed by the champion Noctua NH-U12P. To all appearances, that's the mode where it can reveal its full thermal potential -- symbiosis of an advanced heat sink and an integrated fan starts to work really productively, which helps this cooler take top positions in the final rating (noise-efficiency ratio). However, results of Triton 85 are actually disappointing rather than inspiring -- it generally performs well, but it cannot compete with truly High-End coolers.

Let's have a look at the results demonstrated in the ergonomic domain (noise reference mark -- 31-32 dBA).

Chart 5. Temperature readings (CPU core temperature, ergonomic domain)

Chart 6. Thermal resistance (ergonomic domain)

This situation favors Lion Square again -- it retains its leading positions, getting close to Thermalright Ultra-120 eXtreme. It's an excellent result. Triton 85 is not doing very well here -- it apparently slows down, barely coping with the growing competition, not only from premium coolers, but also from Mid-End products. In fact, it moves down to the rear guard of our today's research. Alas, its results are nothing more than satisfactory, it barely gets to the High-End group.

In conclusion of this section we publish comparative charts of temperature readings and thermal resistance for nominal/reference configurations of today's contenders (maximum fan speed), a chart with temperature readings of near-socket inductive elements (low-noise domain), as well as efficiency-noise ratings (low-noise and ergonomic domains).
