Re: Custom microcontroller fan controller - work in progress
Congratulations on getting it all together in such a professional looking package. Well I didn't really make the package, only the controller PCB. The LCD and the 5.25" sled are off-the-shelf from Crystalfontz. The LCD module is the CFA635-YYE-KL. I had to mod the sled a bit with a dremel but that ...

Re: DIY Temperature Controlled Case Fan Controller Design
Well, I can pass on some of my designs from my own custom controller. Although for your purpose "beyond overkill" would be an understatement. And in a strange twist of fate my first job out of uni this year is as a R&D engineer in Taiwan writing firmware for high powered (~kW) BLDC motors.

Re: Custom microcontroller fan controller - work in progress
Quite the project, Hypernova, I'm sure you're having fun w/ it. Being a mild electronics junkie myself, I can understand. 8) But I have to ask -- what kind of PC system needs 8 independently controlled fans? Future proofing, in the future I might even redirect my graphic cards fan to the controller...

Re: Custom microcontroller fan controller - work in progress
Yeah not much updates, had to finish my Master's thesis first. Anyway here what the board looks like in the PCB design software: http://i.imgur.com/n2dny.png Compare to the physical version: much less glamorous http://i.imgur.com/8KrFy.jpg Here's a little result on the control scheme: The fan is a D...

Hypernova, if you have moved out to Australia you can just buy this kit for $48 from altronics, http://www.altronics.com.au/index.asp?area=item&id=K6120 Intelligent Fan Controller Kit Its a kit you build yourself, can control 8 fans from 4 temp sensors. Setup is via USB and the software is open sou...

This old thread actually came up near top when I googled "digikey fan header" which pretty covers what you want if you want the actual part numbers from mouser/digikey.

Working 7~4:30 is sapping the life out of me... Anyway some overdue updates: -Changed PWM freq to 64KHz, a divider of 500 from the XMEGA's 32MHz. -Don't have a 4A load but so using a 2.9A Delta TFB1212GHE for now for max load. http://i92.photobucket.com/albums/l14/skwf1985/PC080083.jpg Current resul...

Custom microcontroller fan controller - work in progress
Ever since finding out that my Kaze Master have trouble delivering no where near its advertised 1A load I have had the idea of building my own fan controller. Since my degree is in embedded systems naturally it would be something micro-controller based. So here's my starting point: http://i92.photob...

Buck converter looks even more complicated... It appears to be affected by load size a lot. So you need different sets of L and C for different load Would RC filtering the output of High Side-Drivers work? It sure looks a lot simpler I'm thinking of this one So at 15KHz you have R of 0.02 and a cap ...

Some what different topic I have been planning on building my own fan controller for a while. But I am not well versed in the power systems side (my studies are in embedded systems and their programming). So basically the specs I'm trying to achieve is: -No PWM switching noise, so operating the MOSF...

Looks exactly like Scythe Kaze Master except for more wattage and multicolor display. Not sure why you would need 30W per channel unless you're planning on running blowdryers. Nexus 1000RPM fan draws 0.30A which is less than one third of what Kaze Master is rated at. Gentle Typhoons that I just bou...

30W huh? Interesting. The Kaze master has trouble delivering its 1A rating since that's actually only possible when the MOSFETs have sufficient cooling (which it doesn't in the KM). I had to clip a small heat sink to the MOSFET powering my fan stack in my sig rig to stop it from over heating. As for...

HyperNova said: Analog control? Wouldn't it be better with chips like AVR XMEGA's that have up to 24 PWM channels and 16 ADCs? Analog is old school!! I deal with code and digital crap during the day.
