Little Update on the Corsair Fans saga . . . .


18 PWM Corsair SP120's on a single Aquaero 6 PWM channel working perfectly, with the capability for more.

The little "Diva "Dapter" PCB is a gem.


These fans have a min speed of about 840 to 850 rpm, and maxed out at over 2600, but they are stacked 3 high, so there's some boost effect going on there . . . otherwise they max about 2300rpm.


I found the min speed at 50% pulse width, while the fans just hold that speed as you go below 50%. . . So I set min to 50% and max to 100% in "fans".

They have a nice ramp up as you increase the pulse width, maintaining an increase with each 1% increase, even from 97% to 98% to 99%.

The scope shows the pulse shape at the A6 to stay just like it should, and the pulse shape from the PCB stays clean and square as well.


Here's the pics:

All 18 fans under test:




A little closer view:




Close up of the Diva 'Dapter PCB:

The rightmost channel is set up for a D5 pump, while the first 3 are setup for Corsair PWM fans.




Here's the scope at 98%, a very clean pulse . . . A6 on top and PCB output to fan below.




At 99%, the A6 isn't quite as clean, the off time voltage doesn't quite drop to 0V, but the PCB is still looking good:




And a shot of Aquasuite at near max:




Here's how it all looks at min speed at 50%:

Aquasuite settings:



Aquaero display:




And the nice clean pulse shapes on the scope:




I also had some more parts come in and I did a little revision to the PCB to use mosfets in place of the bipolar transistors to get a slightly crisper pulse shape with a couple microseconds less switch lag.

This particular PCB will be going out to the real world for testing running multiple fan channels and a D5 shortly.

Looks great! Did you daisy chain the Swiftech splitters?

They are out of stock everywhere that will ship here . . .

So I got a bunch Akasa triple splitters.

You can see them plugged into the swiftech and a bunch of molexs along the top into some DIY molex splitters.

Enlarge the 1st pic to see them.

Here's the "new" PCB with mosfet switching and jumper selectable setup on each channel for D5 pump or Corsair fans.





I made a small revision which I'll make up for the weekend to use smaller mosfets which have a different pinout.



Looking at the scope, shows the advantage of the mosfets.


The first pic is 99% pulse width with the PCB in the last post using bipolar transistors, while the second pic is 99% pulse width with the new PCB with mosfets









Now if we can just get AC to make a nice version of it to make the A6 much more accommodating, and then they wouldn't even have to change the internal protective resistors or revise it. thumb.gifthumb.gif

If not, you will have people lined up to get their hands on your double ds.

(Diva Dapters of course, shame on you all)

Just had another thought. Put a fancy cover on them and call them "dapper diva dapters". Man I gotta get some sleep...

Could it be because im not using the right zener diode ?
Its written ZPD5V1 on it.. is that correct ?
