Passive mode without system fans (+ prints of the compound)

What are the best settings for Fuma? This is a question that belongs to our complementary review where we traditionally test heatsinks with reference fans. This time in two configurations, with one and with two fans. We went from really noisy settings to completely silent mode. The temperature behaviour is captured minute by minute. Let’s take a look at how this twin-tower handles passive cooling compared to top-notch coolers.

Passive mode without system fans

The load was simulated in IBT – 70,000 cycles with dedicated 5 MB of RAM. This means that instead of continuous operation, the load was pulsing at short intervals. Average consumption was around 90 W.

The motherboard was in the vertical position outside the tunnel. Keep in mind that temperatures would be higher in a case. How much higher depends on how quickly the heat can escape from it. The coolers were horizontally oriented during these passive tests. When you want to go completely passive, this position is more efficient.

The name suggests that this cooler has a matte black finish, which will be appreciated especially by fans of minimalist PC builds. Of course, it will have to be tested whether this finish has a negative effect on cooling efficiency or whether there is any deterioration in acoustics. So let’s venture into the dark future of Endorfy coolers together. Read more “Endorfy Fera 5 Black – Bestseller on the way to darkness” »

For coolers (but also cases) with the Digital attribute, DeepCool creates a built-in display. Its implementation is minimalist in spirit, doesn’t increase the price significantly, and can be considered useful. With regard to monitoring CPU temperatures and load intensity, it’s a thematic value added, which we’ll now look at in the context of the powerful AK620 (Digital) dual-tower cooler.
