I own a Z87-GD65, from what i can tell the main difference are just dual bios, a pipe on heatsinks, more fases of power, but i think the bios/fan control is the same, so you have a pretty nice mobo.
What i recommend with your motherboard is the same I did with mine, get the NF-A14 PWM as many as you want to fill up your case fan needs, get a Swiftech 8-Way PWM Cable Splitter - SATA Power (8W-PWM-SPL-ST)
, i installed mine on the back of the 5.25 cage there is ample room there and noctua fans come with extensions so they will reach pretty easy. Connect the splitter to CPU_FAN2 and connect all the case fans (noctua NF-A14 PWM) to the splitter, remember one has to be connected to the red slot so you get rpms back to the motherboard, connect the sata power (or 4pin molex) to the PSU. Connect the fan of your CPU heatsinks to the CPU_FAN1 (hope its 4pin pwm fan aswell), and then you are set.
Enter the bios, go to the right on the big boxes, you will find Hardware monitor, you will have many options, per default you see the CPU_FAN1 graph and settings (you can change this by clicking the blue CPU_FAN2 icon on the middle of the screen to set up the case fans), from here there is a little testing or tweaking on your part, but its really easy, just takes time as you need to see what results you get in noise and temps to set it up the way you like it, its pretty easy dont worry.
For CPU_FAN2 this is what i recommend you to start with (these are the case fans with the swiftech splitter),
CPU TEMP: 50C minimum and 80C maximum
% fan speed: 25% minimum 100% maximum
The settings above are safe for the noctuas, now you need to decide what are your target temps, personally i like the 50C as minimum as i idle at 30C, so the fans will remain steady at the given % rpm until 50C is reached (this you can change it to be 40 or 45 or 55 or 65, its up to you). I placed 80C as my max, this is important as it will stablish the way the fan will ramp up toward the max temp you wish, you can lower it to 70C or 65C or whatever you feel its better for you, the more temp you give here, the slower the fan will ramp up. The % is also important, the minimum is the least rpms it will have under 50C, i personally prefer a very quiet setup so i placed mine on 12.5% which makes the NF-14 PWM be at 230rpms, but this is very low doesnt move much air, so i suggest you 25% this would still be very quiet, you can increase it 37.5% or 50% if you wish, i just dont have the need to have the case fans that high when its at idle. Personally i limit the top % to 37.5% which is 650rpms, above this to me the noctuas starts to get noticeble, but you can chose whatever you want, i suggested 100% so you get the full rpms when the cpu is loaded, but here you can restrict it to whatever you like, do some testing once you find a setting you like, run prime95 and see how the temps vary upon different settings on the fans.
On the CPU fan (CPU_FAN1) will be the same, im not giving you suggestions into ranges as i dont know what fan you have on it, if you post it and i have any info on it ill recommend you something to start with. In my setup i have it setup temps 50C-80C / fan speed 37.5%-100%, i leave this one with higher range as its the fan that will impact the cpu temps the most. Again this will depend on your fan and heatsink, so im not recommending you use the same as mine on the CPU_FAN1. But if you post me what you have or plan on buying ill give you my best guess to start with.
Now remember all the above is tweakable by you, and the conditions your PC will be, mine atm is not overclocked, but if your is you can decide into more aggressive fan curves or ramping up, but dont worry all this is very easy, its a little time consuming, at least was for me, as i ran prime95 on each movement i made to be sure i was fine with how i set it up, but what i gave you should cut a lot of time on testing, you will just need to check if thats fine for you or adjust it to what you want.
As a final suggestion, dont use MSI software (command center), i just use HWmonitor to monitor my temps, loads and fan speeds. Its very nice also since it reads both motherboard fan headers, CPU_FAN1 (CPUFANIN) and CPU_FAN2 (CHAFANIN), ill leave you a HWmonitor pic of my setup,
If you have any questions once you are setting it up, post it here or PM me, ill help you as much as i can.Edited by Abula - 10/12/13 at 9:19am
