Fractal R5 case fans temp control?

[mealto]

The Fractal R5 comes with 2 case fans and are controlled by a physical switch. It has 3 settings, not sure if its Off, 1,2 or 1,2,3. Just wondering if the case fan speed can be controlled based on cpu temp somehow?

You would have to plug the fans in to your motherboard to control them via a temperature sensor.

not by the case itself - it's just 1,2,3

you need to get a fan controller that can do that or connect them to your mainboard if that can do it

Ok that makes sense. NCIX built the rig and plugged it into a sata port directly from the power supply. I do havr a Z270 board. Would even entry level z270 bosrdd have the proper header to power these case fsns?

My el cheapo business board from five years ago has fan headers, literally every motherboard does.

Its going to be a pain to call NCIX. I yave the MSI z270-a pro. Should the tech have plugged the case fan controller into the MB? If so, can someone talk me through it?

You don't need to bother calling them. Just plug the fans straight into the mother board fan headers. Not sure if your motherboard can do 3 pin control though, have a look through the motherboard's manual. Go to bios and look for fan settings.

I have this exact same board, just plug them into one of the 4 system fan headers and then control them through the bios or the MSI Command Center software. You can set a temperature curve for them there if you wish.

Don't bother calling them. All you do is plug the fan in to the motherboard, and go set up speedfan.

 

Take this:

Install and set up speedfan:

Thanks guys. So, am I right in thinking that I should be using the MB to control these 2 case fans based on temp using MSI's own software and fan curve instead of having the fans run full time (ie. using the case switch to change speeds)?

Yea I mean I would say that totally defends on how loud you want your system to be. A CPU temp curve is definitely going to keep it quite when your not under load. I personally keep my case fans at 100% all the time because I don't mind the extra noise. But it's not going to hurt at all to have them on a curve.

FYI on this don't plug your case fans into the CPU fan header. Save that for your actual CPU fan or water pump.

Thanks @r2good4u. I see the proper 4 pin fan headers on the MB.

 

Now that I think about this a bit more, in addition to cooling, I am going to try and make use of the great front filter on the R5. So, trying to get more positive airflow. What do you guys think?

 

1. Move rear case fan to the front and run dual fronts 24/7 using the MB to control the fans.

2. Move rear case fan to the front and run dual fronts 24/7 using the R% controller to control the fans.

3. Run 1 front and 1 dual (default R5 setup) but use MB to spin front fan faster than the rear to get more a positive airflow environment.

 

Anyone have suggestions here. I don't see any real issues with the temps so far. GPU is small and CPU idles below 40C and never reaches 60C that I have seen under my normal use. In fact, not even sure I have seen anything over 50C for the CPU except running benchmarks. GPU hovers at 25C or below and does not jump even under gaming.

 

Who has done the positive airflow thing and can give me some feedback regarding dust collection over time, especially if you have an R5. Would be appreciated!

Alright, I have plugged the 2 R5 case fans into the motherboard and am running the front intake at 750 rpm and the rear exhaust at 575 rpm at speed up to 70C. These case fans looks like they only go up to 1000 rpm and are very quiet. The CPU fan is louder at 1000 rpm than these R5 fans. 

 

Anyone think the slightly higher intake of 750 rpm (through the filter) versus 575 rpm exhaust will achieve more positive air flow? The power supply is on eco mode and the fan may also contribute to negative air pressure. I didn't want to buy yet another fan so wanting to minimize dust entering the rig. What do you think?
