Delicious. Thanks for letting me know.

id prefer the vario over the pwm. Wish I went for the standard I thought it may have the switch still on the back incase you didn't use the pwm. I like the idea of the pwm but I can see it being a pain.

How so?

Pump increases speed as needed same as the fans do/can. I have mine on the CPU AUX header and the rad fans controlled via the main CPU header. As temps increase both Fans and pump increase.

I'd just prefer a locked speed really which is why I have it in manual. I don't really like passive.

My pump, EK D5 PWM, runs at very low rpms when it's just plugged into the PSU. There's lot of info on the net about it. The general consensus is that it reverts to 60% pwm duty when just connected to 12V but I'd say mine was much lower. When I set it to "full on" in bios I only get about 3500rpms, about 70% so dunno what's up with that. In saying that though, this means I just leave it at full on in bios all the time as I can't hear it.

I wouldn't bother with a pwm pump again because of this.
One more header taken up and an extra cable to manage!

I thought my pump was broken at first, it was pumping so slow when got it. Took ages to fill the loop. When I connected up the whole system and got into bios I was able to increase the speed alright. I thought it would be the same as a pwm fan running at 12v until pwm controlled.
