Idle / OCCT GPU

Fan Speed

As you can see in the graphic a passive cooler doesn't make any noise, well that's what it is made for and means it is noiseless. Now when you mount the S1 Plus Turbo Module on it, the kit stay very quiet thanks to the use of a larger fan and also that the maximum rotating speed of this one stay lower than the other coolers at 30 % fan speed which make it the quietest active cooler here.

Idle Temperature

In passive mode the gpu is hotter than 10°C in average than other coolers as you can see. When active mode it becomes 6° cooler but it doesn't reach as cool temps as other coolers.

Temperature under OCCT GPU

As espected the S1 Plus can't handle the heavy load that OCCT generate on the GPU, the test stopped after four minutes due to overheat, meanwhile as you can see even some active cooler failed this test. As for the active mode, when you mount the Turbo Module on it we can say that it performed very well, it is more efficient than all custom stock coolers we tested being way quieter, almost noiseless.
