I’m trying couple PWM fan to pin D9, after studying your PDF I am using the following hook up: fan: Red +12 Vdc, black -12 Vdc & ground (from stormx) blue, blue to d9 (pwm).
Everything appears to be working as it should, the 12- Vdc hooked to the same terminal as the ground from the storm x causes me some concern.I would rather have my fans do a ramp, rather than jump from the minimum to the maximum, so I would like to rum my fan off one of my available channels. Is this a viable option?
Tagging along. I’m seriously considering the Storm X in order to have variable fan control on the heatsink. However, instructions are very vague and confusing. Description says to use pins D9 and D10 for variable fan control, but the appendix states do not use pin D10 as fans will not operate during sunrise/sunset periods. Somewhere else it states to use in conjunction with relay. Can we please get a comprehensive guide on how fans would be hooked up to increase speed according to temperature, and how to keep them in use during sunrise/sunset? Will order upon having a response. Thanks.
I can be of some help, never got a response so I learned by trial and error. What I have learned is d9 runs at the min speed in night mode, and goes to max mode in sunrise, day and sunset modes. D10 outputs a 5 v signal only during say mode.
My problem was ( is) my pmw fans are noisy and I am doing a 2 hr sunrise/ set . I wanted it quieter during this time. I did use channel 6 to control my cooling fans, and it works as I wanted it to.
All of that said, if I can’t find a lower rpm pmw fan that fits my hood, I’m going to have to switch to standard fans to reduce noise. If I do this I will use d9 to turn on a 12v relay that will run fans during my day period, and have another fan that runs 24/7 to cool during all other periods. Hope this helps you.Thanks for the info, timmydatoolman. I was under the mistaken belief that the fan controller would regulate fan speed according to temperature, such as a motherboard on a computer does. Apparently that’s not the case.
I was wondering what kind of fans you are using. I am looking to get some 60mm Evercool fans. I only found 1 review that says they are quiet, but looking at the dB specs, it seems to me they are going to be quite noisy. However, that’s about the only name-brand fan I found in that size. I found others but they are Chinese generics so I don’t want to take a chance. I’m kind of limited to 60mm or smaller, as they are going in the hood of my Biocube 29.
Also, you mentioned using Channel 6 to control your fans. Would you mind sharing what function you are using the channel for and how you configured it? Thanks.
I wish the would set it up to control fans off temp, I’m using the temp probe to monitor the temp of my heatsink because it’s enclosed in the hood of my rsm 250.
I’m stuck with 60mm fans myself( because of the hood) I have the Evercool, I think coolerguys had a couple of other options, I just haven’t had time to order them yet.
Not sure what you asking about setup, I’m using ch 1 to 5 to run my Lumia 5.2 LED’s, ch 6 runs my 2 cooling fans. I plan on using the next 6 ch to run the lights on my other RSM, when I get around to building the LED for it. Right now I’m running my attinics at 1% overnight and the fans at min speed ( I think that’s about 20%) the fans are not too loud at this speed. During the day my lights are at 35% (I’m acclimating my corals) the fans are at about 40%, that keeps my heatsink at about 80F at this speed the fans are pretty noisy.
Let me know if I can help with anything else.
Which controller are you using, the Storm or Storm X? I thought on the Storm X the fans ran off the D9 pin, but since you say Ch 5&6, are you talking about the Sotrm?
As for the fans, I emailed Ben at Coralux and this is what he suggested: “unfortunately the fans are not temperature controlled. They simply respond to the minimum and maximum settings in the firmware. If you want to mess with the firmware, you can certainly use a temperature sensor and make the fans respond to the temperature. You would use the ds18b20 temperature sensor header, not a fan with a built-in to thermistor. Also in order to have any speed control over the fans, you must be using a 4-wire fan with PWM speed control.”
I guess I bought the fan control kit for nothing – I’m just going to run Vantech fans with built-in thermistors and not hook them up through the controller at all, until I figure out how to program the controller to control them via temp (and since I know absolutely nothing about Arduino programming, that project is likely DOA for me).
I’m using the storm x, decided to use ch 6 so my fans would ramp instead of just going from min to max on pin d9.
I’m using the header connection to monitor the heatsink temp, sound like we both need to find someone who know how to program.
Can you shar a link to the vantech fans I’m looking into other options, the current fans are way too loud, and I’m only at 35% on the LEDs
I bought these:

about the same price on Amazon, but here they are free shippingI’m very tempted to get this kit instead though:
