D5 PWM vs D5 Aquero?

TechMinerUK · 26 May 2016 at 17:31

Hi, I was wondering if it would be worth selling off my current D5 PWM pump to change over to an Aquero USB D5 unit. I was just wondering as the D5 PWM is a pain to use to bleed the loop as without a PWM signal it sticks on the lowest speed

Any help is greatly appreciated

Better with a Vario, no gain with PWM.

D5 USB run at full speed w/o USB/aquabus signal.

D5 PWM is not compatible to all mobo/fan controllers, D5 USB is compatible with all mobo with a USB 2.0 port.

So if you have the cash - Go for a a D5 USB, you can have an extra headroom (albeit a few degrees) of cooling under load compared to D5 Vario.

But in all honesty, D5 PWM is not a good implementation and I'd avoid it until the PWM standard on D5 is improved.

But would it be worthwhile selling a D5 PWM for an Aquabus D5?

If you plan to own a Aquaero system then I would say yes.

+1 on this.

Use your aquaero pwm headers to control your fans instead, a d5 vario on setting 4 or lower is pretty much inaudible
