Still pretty new to this water cooling business, I was labouring under the illusion that you couldn’t reliably slap a pwm controlled dcc pump to a normal 3 pin fan controller which is why Darlene’s test got me so excited. But if you can then that’s just great stuff smile.gif
All in all I prefer to be able to control everything from one place rather than having some of the stuff behind a controller and some behind software. Tends to reduce those “I think we forgot something” moments.

PWM does offer more control,the actual pump motor is no different to the normal DDC,the board is modified to allow PWM control
Much like the D5,the vario can be converted to PWM with a 12euro board from Aquacomputer.

My understanding is that PWM has a better torque curve when used as pump control due to the non voltage reducing method of control.

Righto. That makes a lot of sense. Thanks for this, your answer actually brings together a bunch pwm theory stuff that's felt disjointed so far. thumb.gif

EDIT: just opened my case and stopped one of those Yates.

Oh well, that's surprising but probably less than if they had really been inverted tongue.gif. They're pretty damn good for 3.62€ fans then to be pulling air through that 55mm rad AND the foam dust filter on the Arc Midi R2 biggrin.gif

impossible to beat a loon for the price. best performing fan under $10. frys had the enermax magma on sale a few weeks ago $5. i couldnt make it in time or i would have swapped out all my yates.

Im no PWM expert by any means,IT Diva is leaps and bounds ahead of me with that.

PWM works on 12v being applied on/off over a cycle (duty cycle),the cycle wave is then altered to produce the speed required,the longer on the 'on' part of cycle,the more speed results.

The torque curve is better as the pump is operated fully on at 12v rather than reduced voltage.

This is my understanding,feel free to comment.

Its an older (slight tbh) product so its whatever they have in stock. Its like trying to find things for the 5xx and 6xxx series. What ever is out there is pretty much in stock. I'm sure they're prepping for 9xxx series and continuing to do the 7xx series.

Here it is, with the new smaller tubing (from 19/13mm to 16/11mm) and the EK CSQ fittings and PSC adapters (Some bitspower too):







Looks much better now, I've also added two more AP-15's to the bottom MONSTA rad. I really like this Mayhems Pastel white coolant, it's amazing. biggrin.gif
