Is the cover that has circles and plus holes in it supposed to be removed?

Hi All.

I know nothing about Fractal so need a little input/clarification please on controlling the 120mm/140mm fans.

I am thinking of buying my first Fractal design case. Either Core 3000 or Arc Midi R2 purely based on their cooling reviews. These cases come with fans included. I note however all Fractal Fans are all 3 pin instead of 4. 3 pin means Fractal fan speed cannot be controlled by the motherboard.

I conclude from this Fractal have designed their fans to be used with a controller rather than mobo.

The spec for the Arm Midi cases states: "Fan controller: 1 - Integrated fan controller for up to 3 fans (included)"

I assume this is not a temp monitoring controller and therefore there is a switch on the Fractal cases maybe something like slow/med/fast and therefore as owners you are all changing your fan speed manually?.

Thanks in advance for any replies.

Yes, it is a speed switch. However most motherboards these days are able to voltage control 3 pin fans, in fact, most motherboards only have 1 or 2 (cpu & cpu_opt usually) true pwm 4 pin headers.

Hmm thanks I will check that out. I assumed the 4 pin was always needed.

The 4 pin headers on motherboards (other than cpu ones)are mostly for convenience of being able to run 4 pin fans if you want but they still use voltage to control them typically. The word is that it is not good for pwm electronics to be controlled with voltage, but I believe that pwm pumps are the only thing that it is known to kill quickly. The jury seems to be out on the damage it actually causes to fans!

This is a mobo I am considering

Asus H87M-E ($93)
1 x CPU Fan connector(s) (1 x 4 -pin)
2 x Chassis Fan connector(s) (2 x 4 -pin)
or
ASRock H87M Pro4 ($83)
2 x CPU Fan connectors (1 x 4-pin, 1 x 3-pin)
2 x Chassis Fan connectors (1 x 4-pin, 1 x 3-pin)

I am wondering if things have moved on then and those 1x3 pin connectors will now control the fans in the same way 4 pins do. I cannot find anything on either Fractals or ASRocks website regarding this.

My concern is a Fractal 3pin fan pluged into a mobo will simply run at full speed with no control.

I sent mail to Noctua asking if there was any downside to controlling their PWM fans via voltage, including fan lifetime, and all their reply said was that I wouldn't be able to run it at as low of a speed as PWM controlled.

BTW. You can control a 4 pin PWM fan from a three pin header with voltage control. Why they made those non-PWM voltage controlled headers 4 pin must be marketing. I don't know of a reason.

All the Fractal fans are 3 pin only. i am still non the wiser if the above boards would definately be able to control fan speed or not. From previous experience, being only 3 pin fans , they will simply run constantly @100% speed if connected to the mobo.

Looking to buy a cheap air-cooled , so the Core 3000 came up in my radar. Is there anything I should know of some main agreed upon negatives surrounding this case?

Looking at the manual, that Asus board has a CPU and two chassis FAN PWM headers. Apparently they are all truly PWM.
If it is like other Asus MB, it can detect whether a 4 or 3 pin is fan is connected, and use either PWM or Voltage to vary the rpm.

http://www.silentpcreview.com/forums/viewtopic.php?t=66283p=579280

Whether this MB does that I am not sure. But probably.

EDIT:

Indeed, at least for the CPU fan header for that Asus MB, it has such a switch as you can see in this image:

http://elchapuzasinformatico.com/wp-content/uploads/2013/07/Asus-H87M-Pro-15.jpg

pretty clever

I imagine it is the same for the chassis fan

Oops, I take that back. That image was for the H87M-Pro-15. Here is the image for the HM78-E. It doesn't appear to have such a switch, and I didn't come across anything in the manual that allowed you to set PWM vs voltage control in the BIOS, though I might have missed it.
