Fan setup / connector clarification

post #1 of 11
Thread Starter 
I have old 120mm fans lying around, some of which have the 3 pin style connector and some that have the 4 pin female molex connectors.

I'm wondering what the general preference is for fan connectors (if only one is provided).

Do overclockers tend to always use fan controllers? What connectors do fan controllers provide? I'm assuming that it's the 3 pin connector since that one includes the fan speed pin... is that correct?

And what if you have more fans than your fan controller allows? Do you then connect as many fans as possible to your motherboard and the rest to the controller?

I can't speak for everyone else, but I prefer using a fan controller. I would rather be able to adjust speeds manually than having to open any software.

AFAIK most fan controllers use 3-pin connectors (no need for PWM).

I have 6 fans in my case, 1 connected to the CPU_FAN to keep the MB happy, and the rest hooked to one of these;



This just seems to give me the most control over everything...YMMV.

Just my 2c worth...hope it helps,

Rich

I have a Sunbeam Rheobus and it's great. You can hook up multiple fans to each channel without any issues, and 2/3/4-pin fans all work fine on it. It even comes with adapters to use CCFLs and molex fans with it.

Ah, I didn't know you could connect multiple fans to the same channel. Thanks!

Some motherboard 3pin headers won't fully power a fan. for example in my sig rig, my mobo cannot fully power my Gentle Typhoon AR-15. It requires a fan controller or molex to reach full speed.

Other than that, the connections really don't matter, if your setup is noisier than you like get a fan controller, it will make your system quieter, collect less dust and the fans will last a little longer. On the down side however, your fans may spin a little slower at max speed depending on the fan controller and you may forget to turn the fans up when gaming and such.

I use a scythe kaze q, but I would suggest getting the Sunbeam Rhoebus , it can turn off fans completely and is 5.25" so you won't need to use an adapter.

What about the Scythe Master? It has a better review distribution on newegg, although I'm not sure if I want the blue lit LCD displays.

If it has the same type display as the one I linked above, it's not too distracting. I actually like mine because it matches the blue color scheme I have for my computer.

Also, you can completely shut off the fans with either of these controllers.

I prefer the Master Pro because I have more than 4 fans. The only thing to note is that it will only display 2 fans at once. The knob on the left switches between fans 1, 2, and 3. The one on the right switches between 4, 5, and 6. The six knobs along the bottom each control their respective fan. You can adjust the fans no matter which one is being displayed.

It also has an alarm if a fan fails (can be disabled). The temp probes are easy to place and easy to sleeve. You'll see a lot of folks saying how fragile they are, but I didn't have any problems. They give you 2 extra ones just in case.

Hope this helps,

Rich

Most important thing to consider is the amp, if you look at the back of your fans it should have say some thing like 0.3A. Once you know what it is times it by 12 to get the watts. Do this to the fan that has the higher amps.

So now you need to get one that supports the watts of you fans, any controller around 20watts per channel will be ample. Then if you want lcd or not, how many channels it has(6 channel = 6 fans) then if its lcd it should have the rpm, and some have volts too.

Any fan that takes more then 1.0 amp be always best to run off the controller, but your bios book should have the max amp per header

Be aware im running a AP-30 off the Kaze Master Pro and it needs on start up 16watt, but i have it set for max rpm of 2600, so i know i cant blow the header but is not adsived

More great info, thanks!

Another question for everyone: When using a controller, how do you decide on speed? Do most people use some sort of software / OSD to get real-time temps while gaming, etc... or do you learn how your system behaves and then just set the correct speed manually before starting a transcode or game?

Fan speed is... well, it's a trade off between noise and temps, and somewhere in between (before your system explodes or you go deaf) we find a happy medium that works. I keep my case fans running around 7-9v (1000-1200 RPM) right now, and lower (800-900 RPM) during the winter.... As each system is unique, you will have to find that "sweet spot" that works for you.

For realtime monitoring, I use AIDA64 to keep an eye on CPU/HDD/Case temps, CPU/Mem clocks, voltages, and of course Fan speed. There are other programs around that do this also, like hwmonitor, speedfan, etc.
