To cut a long story short, I have a Corsair Carbide 500R case, under the roof is a XSPC EX240 rad and on the roof is a pair of fans. The fans I had been running were a Scythe Kaze Jyuni 500RPM Slipstream and a Noiseblocker Multiframe S-Series M12-S1. I had these spare (former case fans) when I put the rad in (originally intended for it to be passive) and decided to whack them on as they were silent. I recently decided to upgrade them to PWM ones and bump up my overclock (as the PWM would ensure the fans only got audible during gaming when I would have headphones on).
*However* I bought a pair of Akasa AK-FN059 120mm Ultra Quiet Venom Viper which although inaudiable at low speed from an airflow/motor point made an annoying ticking noise that I could not stand, so having read this was normal via the reviews I then purchased a pair of Noiseblocker BlackSilent Pro Fan PLPS fans and again silent but annoying ticking lol.
Is this a common thing with all PWM fans or just these ones? O.o
