Vardar PWM whine when used with aquaero6XT

[Warchild]

Hi guys,

So up to now I have always been using your typical 3pin Fans. I'm still running my 900D with two rads all in push n pull. Previously they were just cheap £9 EK Gelid fans and it had me satisfied to an extent. Controlling via the aquaaero x6t has been simple and highly rewarding.

Finally though, I was enticed by the Vardar fans from EK particularly the PWM versions.

Now initial setup I had them running at a fixed pwr of just 33% and while quiet the PC does get toasty when everything is over-clocked. I am well aware, that PWM fans can have an annoying whine at low duty cycle, and some people have resolved this by making their own little circuits with diodes and resistance.

However I was a little surprised at how bad my pwm fans whine when I set them to be controlled by the CPU temperature. <34% or >60% there is no noise, but in-between they really squeal. I can live with a hot pc and stick with 33% but I'm always keen on improving and fully understanding the Aquaero controller.

Anyone have advice or tips on reducing this noise perhaps someone with experience with the Aquaero 6Xt.?

I suspect it could be due to my cowboy fix of daisy chaining 14fans on one channel via EK 4fan to 1fan connection and the likes.

Not really... I've had some Vardar PWM fans as well, and they're just really terrible. It's all about opinions of course. We all have our prefered brand. I've been using Noctua for the last couple of years and never had any issue with their fans. They don't make weird irregular noise and they have excellent performance.

I'm sad to say that those EKWB Varder fans are hyped far beyond belief.

Well to be honest, performance wise, i disagree, they are outstanding. My only gripe is as you say, the terrible noise.

I know Noctua are le crème de la crème but in Norway, they cost £35 each. Im not gonna drop that much cash on one fan. When it comes to watercooling I am not a brand fanboy, ill go with what is best/cost effective. Hence the Vardars.

So yeah, happy with performance but not happy at the noise in the mid range.

£35?! Is that the industrial og brown version? You can get the industrial versions for about £20 at Caseking.de (Overclocker.co.uk)

I could but then i have to pay import tax so price comes to the same amount pretty much. and thats the industrial version.
