What Specs to look At when Purchasing Fan Controller

post #1 of 9
Thread Starter 
I have 2 GT AP 30's (modded to 3 pin not that it matters and want to buy a fan controller for them. What specs do I look at on the fan controller to make sure my 2 GT 30's (and maybe a couple other fans) will work successfully on ie) control fan speed & monitor fan speed etc etc.

You need to look at the max wattage output per channel. For instance, my fan controller can output 20 watts per channel. Each of my fans require 3 watts of power. I can use up to 6 of these fans per channel. Check your fan power usage, and look out for wattage per channel. These are the key elements to be aware of before purchasing a controller.

Figured this out this morning thank you very much for the reply man

In the other thread you started on basically this same topic, "Fan Controller For Gentle Typhoon AP-30's", this question has been answered for you already as best as anyone could. I'll post the rest here not-so-much for your benefit, but for anyone else who stumbles on this thread with the same question in mind.

The AP-30 are high rpm fans with high wattage / voltage needs, so you might not want to put them on a really cheap controller, but since you only have two of them most any fan controller will do, especially if you plan to put each fan on its own channel. If you want to put both fans on a single channel then you should be looking for a controller rated at 30 watts per channel or more.

To recap: Here's the manufacturer specs of the AP-30:

That fan is rated at 0.56 operating amps = 6.72 watts
Its starting amp rating is 1.35 amps = 16.2 watts
Its operating range is between 10.2 to 13.8 volts.

Like most things,you get what you pay for.

^ Those are just three popular fan controller options.

The first one, the Aquaero 6 XT, is hands-down the best fan controller you can buy. It can do a LOT of other things besides a very advanced ability to automatically adjust fan speeds based on temps. It can monitor flow rates, control pumps, RGB light strips, and a lot more. Plus, it can be controlled via the controller itself, through software w/ your keyboard & mouse &/or via the remote control that comes with the XT model.

The Lamptron CW611 is a VERY good watercooling-oriented fan controller also, and it runs a little less than half the price of the AQ6. It can also monitor flow rates and could also be used to control a pump, but its interface is a bit clunky and lacks any of the extra features like software/remote control that the AQ6 has. One good feature of the CW611 is its automatic fan control lets you set a min & max fan speed setting for a channel based on a target temp from an air or water temp sensor. When the temp is reached it will slowly step up speeds towards your max setting if the temps continue to increase.

The Lamptron FC5 is a good basic 30 watt per channel fan controller. Its main selling point is the touch screen, but it can be a little tricky to work with. It also has a temp-control automatic feature but, as is typical with most fan controllers with automatic speed control capability, when the temp setting is reached it will ramp the fan speeds up to 100% until the temps go below your setting. edit: my apologies. I was confusing the Lamptron FC5 with the Lamptron FC Touch. doh.gif


A headsup. You will not find anyone here on OCN or elsewhere with more experience with watercooling who so freely gives as good advice as B Negative on such issues.

A headsup. You will not find anyone here on OCN or elsewhere with more experience with watercooling who so freely gives as good advice as B Negative on such issues.

One important thing to know about the CW611 is that the manual and online instructions are not correct. As Unicron has said the CW will ramp up ran speed from the target temp you set. It will adjust the fans smoothly from the target temp on a 10C temp curve so that for instance if you set 30C as the temp the fans will run at your min setting at 30C and below and slowly ramp up to your max setting at 40C.
It is a much better auto system than most other fan controllers that will just set the fans at 100% if the target temp is hit til the temp drops under target temp.

So for now I went with the NZXT Sentry Mix 2.

Its a basic fan controller with 30 watts per channel.

B negative was saying he can get his to 5v with a lamptron controller (not sure which one) but the fans voltage range is 10-13v?

Is that possible because he has a really good fam controller or did he make a mistake or typo or something like that?

Happy Easter all.

B Negative didn't say "he can get his to 5v".

It was PepeLapiu that was saying he can get his 2150rpm AP-45s to do that, and he (incorrectly) implied that you should be able to do that same with your 4250rpm AP-30s. But, as was pointed out on that thread by myself and B Negative, over and over, Pepe was mistaken. His 2150rpm AP-45s (aka AP-00) are a completely different type of fan than yours. His AP-45s are a "low-speed' design grey bladed Gentle Typhoon with a min operating voltage of 5v, similar to a Gentle Typhoon 1450rpm AP-14 or an 1850rpm AP-15. Here's the manufacturer spec sheet on all 3 of them (PDF).

Your 4250rpm AP-30, on the other hand, is a "high-speed" design black-bladed Gentle Typhoon with a min operating voltage of 10.2v similar to a 3000rpm AP-29 or a 5400rpm AP-31. Here's the manufacturer spec sheet on all 3 of them (PDF).


What B Negative said was: "they can't Low,I have some of these fans,they slow to minimum of 1200/1400 rpm then they stop." In other words, they don't do low rpms very well. Once you get them started (which is probably going to be somewhere around their manufacturer rated 10.2v min operating voltage) they are going to be going at a faster speed, and at that point, once they are moving, you can then try to dial them down slower only to around '1200/1400 rpm then they stop'.

The Gentle Typhoon 'high-speed' fan lineup (AP-29, AP-30, AP-31) are not meant to go slow or be quiet. They are meant to blow like a typhoon.

Ok,we can go thru this again...

The controller should be be specced to the amount of fans you want,In the interest of maintaining the controller (these are weaklink components,they are not bombproof....even more so if you go very cheap.)I would spec controller according to the start voltage requirements. Not saying you can just spec on running draw,many people do but its good practice and beneficial to the controller not to overload it.

Lamptron are the top of the pile for reasonable cost but mighty channel power,even the lower spec units are pretty reliable.

Look closely at the fans you want to control,if they are high speed fans then min/max voltages are going to be critical to reliable fan control. If they are 4 pin PWM fans then you will need a PWM compatible controller,some PWM fans (Corsair...looking at you here) run a PWM spec that can be incompatible with PWM industry standard.
Most 1600 rpm fans will slow to a near stop,PWM fans also have a large speed range.

Unicr0n has also told you the same thing in the other threads you have started.

Okay yah I thought so b neg but pepe threw me off when he said that so I'm just making sure he's wrong and its not possible.

I figured he was wrong when I saw you talk about the operating voltage range on my fans as 5v is literally half of the lowest volts my fans can run on before turning off as you said.

+rep @B NEGATIVE you've been extremely helpful and I've learned a lot from your posts in my thread.

I can't believe how much cooler my load temps are with these fans it's pretty sweet I gotta say! That being said if I'm being honest they definitely aren't quiet however the fan controller does help bring their noise down a good amount.

Really appreciate everyone's help and happy Easter to everyone!
