The temperature/noise ratio
On these perf/noise ratio graphs, we remind you that the best is to be placed as much as possible at the bottom left of the graph. For the reading, the left most point symbolizes the ventilation in 12V, the one in the center the ventilation in 8V and the right most in 5V.
With our processor consuming 100W, we feel that the H170i Elite LCT XT is rather comfortable. It is positioned between the two Ryuo III from Asus, showing that it is more at ease on the low rpm. On the other hand, it does not manage to compete with the Liquid Freezer II 420 from Arctic, which looks formidable, the Swiss kit burying all the competition!
With an increase in consumption, we feel that the kits with large radiators are largely favored over the others. Moreover, we notice that Corsair’s model is getting stronger by tickling the Ryuo III and Arctic’s Liquid Freezer II very closely. However, the Swiss kits have a definite advantage when it comes to noise pollution. 
Clearly, when our processor consumes 200W, the leader remains the Liquid Freezer II 420 from Arctic. However, the H170i Elite LCD XT does well, although it is also outdone by the Ryuo III 360… Which hardly manages to be discreet at low rpm.
In any case, Corsair has managed to greatly improve the situation compared to its H170i Elite Capellix and it shows a lot.
