This is my favorite trick when it comes to PC cooling

No more noise.

The 12 cm diameter fan has a speed of 1100 rpm (with a standard deviation of 10 percent), so its noise load is relatively modest, up to 22,5 decibels, according to the seller. Available in blue, green and red, the product has a life expectancy of 30 hours, as it is illuminated by definition, and the maximum air delivery of the interestingly designed blades is 000 cfm. Based on its parameters, the Cool Wind is eerily similar to the popular Arctic Cooling F45, only it ignores the light effects and is even more expensive.

Cool Wind is not a noisy wind turbine.

And now let’s look at the “trick” heralded in the title. If you have a motherboard with, say, only one motherboard fan connector, but would like to use or control multiple dust mixers, you may want to consider this product. As you can see in the video above, you will need to connect the 3-pin buckle to the board, after which you can connect the other fans to the molex branch. With this method, you can implement voltage-based control by configuring the chiller speed in the BIOS - obviously this will affect all units. It is worth noting that it is not advisable to connect more than three fans in this way.

The price of the Segotep Cool Wind is really pleasant, exactly $ 4,36, which is HUF 1100 at the current exchange rate.
