Sorry I can't go into more information as of now since I don't have any more. As for a guide to install the PCB board follow the link below to where I posted a full video guide to do this.Quote:

So what makes you so sure someone is releasing a PCB w/PWM enabled/integrated?Quote:

I keep in contact with DIYINHK regarding this board and future products since I am interested as well. I have made suggestions and I know a new revision of the board will be out in about 2 weeks. My guess is PWM will be added either built in or individually.Quote:

So I never actually did install the DIYINHK board since noise goes up :(
Though I have been interested in controlling my pump via motherboard since the new sandybridges don't work too well with S3 and so my computer is on 24/7. What was posted about making the PWM signal into analog seems to work. Simple google search returns: http://www.makingthings.com/wiki/analog-output
This site explains how it works. It looks like all he'd have to do is change the circuit board a bit to allow a resistor and capacitor to be soldered on. Then you could just attach it to the motherboard. The PWM Signal that is.
^ A "mea culpa" on my part here, Swiftech did send me the correct rev2.Quote:
And yeah PWM helps too, when swiftech sends you the correct freakin MCRx20 Drive revision! :mad:
There was a rev2b released in Jan. that looks slightly diff, but apparently has no affect on performance/functionality.
That's where the confusion slipped in, I do have the rev.2 & all the improvements that entailed.
Sorry Gabe for making claims before they're substantiated, or even at all until the issue was resolved between us.
I do agree though that there needs to be clearer identification of new revisions, so this confusion doesn't occur again.
Yeah but WRT raw performance & efficiency it's substantially better right?Quote:

Thanks for the further thoughts mate,Quote:

I don't understand why he'd want to do that...
Particularly since it's been determined that it's possible to enable it on the PCB.
Surely the better option would be to enable it on the PCB?
I don't know if it will be separate or on board, but I can see good reason for wanting it separately. If it is a standalone controller you then have the ability to control anything with it. Any pump and any fan. To me that has value. Who knows many it will be released as an independent controller along with on the new revision of the board. We just have to wait and see.Quote:

Imho direct pwm support in controller board (if it's possible to implement with pump controllers on these replacement boards) would be better solution.
I might be wrong of course, as my knowledge on electronics is veeery vague at best.
Here is a comparison of the Toshiba on a DDC3 series rotor vs a DDC3.25 (Dashed Purple) motor I did a while back.Quote:

i just purchase 2 10w version today...
this gonna be fun :)
Yeah that's exactly what I'm worried about....Quote:

You'd still have all the inefficiency/heat assoc/w LVC*...
And because it's LVC masquerading as PWM, you wouldn't have the finer-grained control one can get with PWM.
Not that you'd necessarily need that finer grained control for a pump!?
*linear voltage control
Sweet, thanks mate!Quote:

If anything there is more noise from PWM vs Linear, but PWM is easier to control. Good thing I have all gentle typhoons so any heat/inefficiencies are down to ~3 watts for 7 fans. For those 3 watts, I get less noise. I think its worth the trade off.
^ Hmm, doesn't smell quite right based on what I've read gurus in this thread write:
http://www.overclockers.com/forums/s...d.php?t=641111
But I'm not terribly knowledgeable in the area, so I'll take your word for it!
I just hope we get more info. about the approach DIYIHNK has decided to take soon!
Now there's a new version for our modding guys. It looks pretty nice, but nothing for me. ^^ The controller is the same.
http://cgi.ebay.de/Laing-DDC-pump-18...43696023167123
do want. I can solder rather well, maybe I'll dump my 35xs for this, I have a few DDCs kicking around...
Cool ideal with the LED option..:up:
yeah, but the components are not pre-soldered :(
Hello Guys,
Slightly off-topic, but seeing this is the DDC-pump thread.....
Do any of you know if the DDC 3.25's have a NTC 10k thermal sensor on the PCB somewhere? I am planning to mount Koolance sensors to mine, but was hoping there was one already, so I could just tap off that into the system.
Appreciate your feedback :)
Would be a nice feature.....
Soldering is done in 15 minutes :DQuote:

Guys I have a few on the way and I put in my feedback of people asking completed boards. I am sure though since they were offered before they will be offered again. As for features I will post a full list once my boards come in.
Oh so DIYHNK's still in testing stage & not offering any more for sale to early adopters?Quote:

Unfortunately post linking is broken for now, so I can link directly to them.
The new revised boards are available now. They just aren't available are pre-soldered versions (yet). http://cgi.ebay.com/ws/eBayISAPI.dll...m=330579999664Quote:
