Scythe KazeQ and weird fan speeds.

[thejamppa]

Hi all!

I made some testing. I have Scythe Slipstream 800 RPM exhaust in Antec Solo case and two Nexus Real Silent Basic case fans front. I control them with KazeQ.

In open Air Slipstream is around 810 RPM's with Kaze Q. Tha is my reference.

When Side panel is off Rear exhaust is around 810-813 rpm's. Front fans are minimum.

When case is closed and two front fans are minimum rear exhaust is 880-890 rpms.

When both front fans are full, the rear exhaust drops in 830 rpm range.

With Single front fan full Exhaust is around 855 rpm range.

This seems quite weird. Is this air impedance / air flow which affects fans or is it that somehow my Kaze Q's channels are affected by load / voltages of each other's voltages or such?

There is nothing you should worry about because all this is in the normal tolerance range of around +-10%. A fan never spins at one exact rpm speed. Sometimes it will be higher or sometimes lower, all this is effected by air flow, pressure and many other things.

Hi thanks. I came that same conclusion after running more tests in various Scythe Slipstream's and Nexus Real Silents. Fan speed increases as more impedance fan has. Closing case makes fan run higher speeds than if your case is open. Since Slipstream is low impedance fan, it takes more hit in higher impedance. Now I will get some Gentle Typhoon's and look how they fare ^^ I always wanted an excuse to buy Gentle Typhoon's now I have one ^^
