ICue 465x RGB - Fans Question

Recommended Posts

Hello guys.

I've finally got the Icue 465x case. As known, it comes with the 3x120 LL rgb fans mounted at the front.

My actual build with the old case has a push pull configuration with:

- the Hydro H150i PRO RGB which comes with the 3 120 ML fans mounted at the front with the rad

- 3 x ML 120 Pro Fan (2 top and 1 rear).

 

Till now, thanks to the commander pro and the Icue software, i haven't got any problem in setting fans speed (since the performance of the 6 fans are actually the same and all of the have the same min and max rpm performance).

Now that i've got the new case which has the 3 LL fans i don't know if i could use the LL as front push fans attached at the rad or i have to remove them in order to use the ML fans.

My question comes because i've seen that the LL fans have lower speed compared to the ML and i don't want setting or calibration issues.

 

So, what do u suggest me: continue with the actual configuration which means i hav to remove the LL fans and place the ML (from the Hydro) or leave the LL RGB?

Thanks a lot in advance for your attention and your time.

Hi Jospher,

 

The fans are controlled via PWM meaning that they get sent a % signal, so you will not have any calibration issues - some fans will just spin faster than others.

 

Please note that I would advise you to have your 3 radiator fans connected to the wires coming off your H150i PRO RGB so fan speeds will be controlled depending on the coolant temperatures in the cooler. This will give you the best noise/performance ration instead of running the fans off a commander PRO and CPU temperatures.

 

Your remaining case fans can be controlled via your commander PRO.

 

You will get a slight performance loss from using the LL fans on your radiator compared to the original ML fans, but it should not be anything major as you have such a large cooler.

Also since the Commander lets you set individual fan curves for as many sets as you like, its easy to set one curve for the ML and one for the LL side. You would not want to run the ML at 2400 and the LL at their 1600-1700 rpm max. Large difference in fan speed/air flow make one side or the other resistance to the stronger. That typically manifests itself in weird tones and noises. The Commander uses RPM as fan programming so it is simple to keep the two sides on track even though they may be on different fan controllers (AIO and Commander). They don't have to be exact and sometimes when using mismatched fans on either side, you may find the tone more pleasing to run one side or the other +-100 rpm or so. That is about sound quality and not performance. Once you get too far apart, other unwelcome things tend to happen.

Thx a lot for your help. Regarding the 3 radiator fans i've always had them connected to the wires of the H150i pro rgb using as temperature reference the liquid one and using the ComPro for the other 3 fans. As temperature reference i've always used the liquid one (the H150i temp shown in the Icue software) and everything has been always good.

I'll try this new configuration althoug i think i'll have the real performance when the ambient temperature raises a bit during summer.

Thx a lot again and thx for this nice and helpful forum.

Yup, thx for your reply. it's exactly what i already do thanks to the Com Pro and the Icue software. I've drawn my custom curves and till now they worked great.

thx again
