Fan Controller MOD

I installed this fan controller in both of my home computers. It greatly reduced the db that the fans were putting out. I turned the fans to the slowest voltage ( 7V ) and the temps only rose a few degrees celcius.

hmm, I can't figure out why my link is not working?

 

the link you need is http://home.nc.rr.com/xcal/mod.gif

Ive also got a similar fan controller, very usefull things!

 

Aye they are very helpful things.. and fun, too...

I've had this one in for a little while, cuz I was able to mod it and mount my CM Aero fan control knob in it...


This one I just installed last night... goes in 3.5 slot.. very cute...


This one is on the way...


This one is mounted in the cabinet that holds the pcs and controls fans in the cab...


This one I tried a mod on and destroyed it...


and this one I returned.. quickly! (altho it does have a nifty 0 - 12volt range, allowing you to shut a fan off completely)...


What? Images don't show in this forum? And I even made the background color match MG... /sigh

I built my own with a couple rheostats for the fans and a switch for the Cold Cathodes.....

it is nice to turn the fans down when it is cooler for the extra quiet!

 

jonsimmonds, thx for fixing my link. What was the code you used? I used

 

you had www.home.nc.rr.com/xcal/mog.gif when it should have been http://home.nc.rr.com/xcal/mod.gif (no www needed in the link you gave )

Also anyone know whats the best fan controller that will measure temps and adjust individual fan speeds to compensate?

 

Individually adjust each one automatically, according to the temperature around that particular fan? That's one I'm not aware of... but I wouldn't want to deal with it if I knew... the Qfan is annoying enough with the sound of fans dragging when the and whining now and then... some of those little motors sound so bad when they running at certain rpms... and get 3 or 4 of them doing that... oh it'd be a circus in my head..hehe. But mine is too close to me and too open. A properly tucked away box that's all sealed up and insulated would be great with somehing like that. Seems like it wouldn't be too hard to make.. hmmmm.

Does anyone know how to get an adjustible fan (like the Aero 7) to work with a standard voltage-regulator type speed controller? I can't seem to get the right combo of wires or something... Thanks.

 

I would asume you get the areo's potemitoreter and cut it off, and attach both wires, this should make it run at full speed (of it it makes it run at slow speed leave the wires unattached) then attach the fans power cables to the fanbus.

as to the advanced controller im prob wishfull thinking,, just wondered if theres anything out there that did that

 

Ah well I got it working... I attached an adjuster knob from a TT fan and set it on high and tucked that end away, plugged the +/- into the new musketeer fan in and left the musketeer yellow mobo cable dangling and plugged the aero's mobo wire in. I started to splice them together, but that would be pointless as that is just to keep the mobo happy that something is talking to it. Fired it up and it worked! Yes, both adjusters control the voltage, but I'll just keep the one internal all the way up and fiddle all I wanna with that nifty sliding job out front. That's a really good looking unit.

But now here's a question. I thought they were just being quaint with that "sound pressure" thing and that just meant it was a volume control. Nope it's connected properly and it's not volume. The VU needle moved accordingly with the sliding adjuster, but I can't tell what it's adjusting yet. To install, ya have to put in a little pci cover with in/out stereo jacks - ya run the sound card out up to the new pci adapter's in and run the adapter's out to the speakers. Internally a cable runs from the adapter to the unit to adjust "sound pressure."

Did they release this unit on April 1st?

 

SOUND PRESSURE
--------------------------------------------------------------------------------

The atmosphere exerts pressure on all objects in it. When a vibrating body moves in air, it creates slight disturbances of the AMBIENT atmospheric pressure. The AMPLITUDE of these pressure variations (that is, their maximum displacement from the ambient atmospheric pressure) is called the sound pressure variation, whereas the effective pressure variation is 0.707 the maximum value (see ROOT MEAN SQUARE). The oscillating variations in sound pressure (called the WAVEFORM of the sound) PROPAGATE in the form of a SOUND WAVE.

See: ACOUSTIC IMPEDANCE, COMPRESSION, LAW OF SUPERPOSITION, PARTICLE VELOCITY, RAREFACTION. Compare: ACOUSTIC RADIATION.

When the amplitude of the vibrating body, such as a tuning fork, is greatest, its velocity is zero (that is, it has reached its outer limit of displacement and is momentarily motionless before returning in the opposite direction). If the velocity is zero, so is the pressure it exerts on the medium (e.g. air) around it. Velocity (and therefore pressure) is greatest mid-way between the maximum displacement of the vibrating body, and we can graph the resulting relationship between amplitude and sound pressure in the following way:

<< insert funny graph here>>

Sound pressure variation of a sine wave showing the PHASE relationship between pressure and particle displacement.
For other versions of this graph, see CYCLE and SIMPLE HARMONIC MOTION.

It is the sound pressure rather than the actual physical INTENSITY of the wave which our EARDRUMs and MICROPHONEs react to. SOUND INTENSITY is proportional to the square of the sound pressure and so we may calculate intensity (which is difficult to measure) by measuring sound pressure (which is relatively simple to measure).

See: DECIBEL, SOUND LEVEL, SOUND PRESSURE LEVEL, THRESHOLD OF HEARING, TRANSDUCER. Compare: LOUDNESS, POWER, VOLUME.

Sound pressure may be measured in dynes per square centimeter (dynes/cm2) or Newtons per square meter (N/m2) where 1 N/m2 = 10 dynes/cm2 @ 10-5 atmospheric pressure. See Appendix D for the conversion of pressure ratios to decibels.

edit:: wait a minute! Is this reverb???? OO OO .. I'm plugging this thing in!

 

HUH!!!! LOL

 

ive just installed a silver musketeer and its the sweetest thing ever i dont know too much about the technicalities but i followed the instructions and when i play music the vu dial pings up and down awesome
the blue dials have to be seen to be believed

 

Oh yeah, I love the unit and it will be the only one I've installed that I don't take out in a few weeks to try a different one. With the other blue lights on my system and surrounding area, it's really satisfying to look at. I want to post some pics as soon as I borrow a digital cam from a friend. (still haven't broken down and bought one)

Only gripe is, yeah, the VU meter pings to the music, but really I haven't seen any practical application for the "sound pressure" function. But it's really neat.

Also, I do miss having a more detailed temp reading for the processor. The needle is stable and seems accurate, but 1/64 of an inch variation can mean a couple deg. celcius and the analog display just isn't that granular. But tha's ok... until I have an overheating "problem," that bad boy is staying in there.

Yea, my link should be http://home.nc.rr.com/xcal/mod.gif

 

Ah, finally borrowed a digi camera from work and posting my first pic of my rig after all this time in MG.

Too bad this room doesn't have pics enabled... oh well. Unfortunately, the darn camera didn't have any flash options.. it was just ON. So I had to block the flash with my hand, but the glowy picture came out lousy. The lights are much brighter than you see here .

sp/\z

 

Nice

 

thats a sweet looking setup id love to show a few pics of mine ive got the images on my pc but i have absolutely no idea how to put them up

 

djl147, you need to have wwebspace to put your pictures on. The you link the picture to for say......this post with an html command.....for say

Its really not that hard.
