PWM Related fan control question - Page 4

post #31 of 36
I think whenever Jack's chip is pushing in the 80's, he just feels better hearing fans full speed.
It's like that theory about helicopter props designed to cool the pilot. As soon as the prop stops, you see the pilot starting to sweat.
So whenever Jack's chip goes in the 80's, the fans go into 100% speed in order to cool both the chip and Jack.

This was also one of the things I've noticed with my loop. Letting my CPU control the fans is not better than setting my fans to 750 RPM. I can set them to 650, but there was no noticeable difference between 750 and 650 sound wise, and temp wise there was a 1c difference. With the inline temp sensors in my loop, water temps never broke 35c, and I'm well within the temp threshold of the CPG and GPUs.

PWM controlled pumps was the only thing that made sense to me after all my testing. Good thing the Rheosmart was cheap. My next test will be water temp based control with the Lamptron Touch and CW611 when it arrives this week.

Thanks for all of everyone's input on the subject.

You bought both the Touch and the CW611?

I've had the Touch. I got a CW611 for Gits and Shiggles. I'll probably end up using the CW611 for my main, and use all my spare parts for another computer I've been meaning to put together.

Yeah, that CW611 looks very promising.
I would have mine right now if UPS hadn't screwed up on me.

I understand the CW611 doesn't use the same tech as the Touch. It actually is really voltage control, not a modulater like the Touch.

I fried my Touch last month. Apparently, you can't put 40 watts of fans on a single 30 watt channel.....go figure!
I can't wait to get my hands on the CW!

The CW611 is a nice device. It is the only other digital controller I would consider using. (til the EK one is released and we see what it can do anyway)
Just set your max and min fan speeds/power then set a target water temp and it will use a 10C curve, min to max, from target. Should give pretty decent control for a water loop. I haven't put mine in a loop. I just use it for testing because I got it super cheap ($40) from a local forum.
Its fiddly to use for manual control but the the auto is a least half decent compared to the terrible systems other digitals use.
