I don't think that adding the 2 fans will "damage" you system. Worst case is the thermals aren't as good as they could be. Find a good CPU & GPU stress test and run it until your temps stabilize and write down your numbers. Then try adding the fans and see if it's better or worse. Try to only change one thing at a time so you don't confuse the results.

Also, there probably isn't a need for an additional fan controller since you can probably just use a fan splitter. I've seen several builds where the 2 top fans are on a single fan header and the 2 bottom fans are on another fan header. Keep in mind that all the fans on the splitter will get the same %PWM signal. Also make sure to not have more fans than your fan header can drive. The MB manual probably lists the max wattage per header.

Fan splitter cables are a few bucks on Amazon. These let you connect two fans to a single header!

RGB fans connect to both your fan headers, as well as a separate RGB/ARGB header on your motherboard. Make sure the fans you pick up will work on your board!

actually i think you will need two two way fan splitters here you go: https://www.amazon.com/JBtek-Black-Sleeved-Splitter-Converter/dp/B01EF9OI0O/ref=sxin_12_ac_m_pm?ac_md=1-0-VW5kZXIgJDk%3D-ac_d_pm&cv_ct_cx=fan+splitter&dchild=1&keywords=fan+splitter&pd_rd_i=B01EF9OI0O&pd_rd_r=25c22c53-db9c-453a-8188-1923e3b82e51&pd_rd_w=sQt0N&pd_rd_wg=ZrM7Y&pf_rd_p=cecfef36-6622-42a0-9171-7212303b5ca3&pf_rd_r=7EHNF0KFK9KCZAWV05ZW&psc=1&qid=1596129823&sprefix=fan+splitte&sr=1-1-3f74d940-526b-436f-a83d-f486577edf4d

they should all be 4 pins but you can plug 3 pin fan plugs into them they're designed to be universal. just line up the little plastic thing that keeps it aligned.

if you only need 2 this one is even a little cheaper: https://www.amazon.com/JBtek-Black-Sleeved-Splitter-Converter/dp/B01EF9OI0O/ref=sr_1_3?dchild=1&keywords=fan+splitter&qid=1591403803&sr=8-3

Fan splitters aren't things that are terribly complicated, so just about anything should work. That said, I've used these in the past with no issues.

definitely prioritize the cpu pump in the CPU_FAN slot. For the others, I'd expect you to have another 3-4 fan connectors on the motherboard which should get you just about where you need to be. My cooler (corsair) came with one splitter (y-connector whatever you want to call it) that I used for the fans on the radiator, check your box to see you got one. If not, you can order some and in the meantime connect the one or two left out fans directly to the PSU but as another person mentioned, they will run at full speed until you get yourself some splitters. something like this

Yes, the d15 will fit, they always have a few mm of wiggle room in cooler clearance specs. Buy pwm fans and plug them into the mobo so the speed is variable. You should pick up some fan splitters to plug them all in-

Step 1 - Unplug your CPU fan from the SYS_FAN header and move it to the CPU_FAN1 header.

Step 2 - Buy one of these and use it to plug the two case fans into the SYS_FAN header.

How about https://www.amazon.com/JBtek-Black-Sleeved-Splitter-Converter/dp/B01EF9OI0O/ ?

You might be able to find (more) cheaper ones on eBay.

Arctic has budget 120mm fans which are also good performing, you can check those out.

I have a tomahawk and 6 120mm case fans. I got a 2pk of fan splitters that brought th E number of headers i needed from 6 to 4. These are the ones I got.

That link says there's also a chassis/water pump fan connector. If you're not using that one, you can use it for a second case fan.

Alternately, you can use a splitter cable, although then both fans will have to run at the same speed (which is probably what you want anyways). Note that I just found that cable on Amazon, I'm not specifically recommending it. Also, my case or fans or motherboard or some part of my build came with splitter cables, but I don't remember which part.

Of course! You can pick up a cheap 2 way splitter like this one which I personally use: https://www.amazon.com/JBtek-Black-Sleeved-Splitter-Converter/dp/B01EF9OI0O It splits into two other 4 pin slots but 3 pin fans will work with it

Looking at page 4 of the Mobo manual, there are two things called "SYS_FAN". That is where you plug your case fans into. If you have more than 2 fans, you'll need to buy fan splitter cables so they can all connect to your Mobo.

Example here:

My bad! I was looking at the B450A pro max. I forgot to include the M.

You are correct that your board has only two fan headers. You can just get a PWM splitter cable for your two case fans, and plug your cpu fan where it goes.

The pump goes into either cpu_fan, cpu_opt or preferably aio_pump if your motherboard has one.

Your Kraken X52 should have 2 fan headers coming off of the pump head, connect the 2 AIO fans to them and you can control them via CAM.

For your other 2 case fans, connect them to any 2 fan headers on your motherboard. If you don't have enough fan headers, you can get a splitter like this.

Well you need 9 headers for that so I'd recommend just getting a couple of pwm splitters on Amazon https://www.amazon.com/JBtek-Black-Sleeved-Splitter-Converter/dp/B01EF9OI0O/ref=mp_s_a_1_4?dchild=1&keywords=pwm+splitter&qid=1593904853&sprefix=pwm+split&sr=8-4

I’ve got an old mother board with only a few fan header spots so I’ve had to use a splitter to set up my aio radiator but of the two fans connected via splitter, one runs at like 100% while the other runs with the curve. Any solutions to have them both follow the curve? Link the the splitter I’m using :splitter Fans are two noctua nf a12x15

Thanks. I used fan splitters on 3 of the ports to split 2 fans- if you do this just make sure your fans won't overload the commander pro. So 6 fans on 3 ports and 3 fans on the remaining 3 ports.

These are what I'm using and they work fine, zero issues - https://www.amazon.com/gp/product/B01EF9OI0O/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I'm also using an RGB splitter for the 3 EK blocks I have. Works fine but the gigabyte software will recognize them as a single part if they're split off a port. Too bad iCue doesn't recognize EK products!

You can get splitters that let you plug in 2 fans per header, that'll be your best bet. The fans the share the splitter should best be the same size make and model if possible, but it's not a gigantic issue.

Something like this would work https://www.amazon.com/dp/B01EF9OI0O/

And connect both to the free Chassis header.

Don't worry, the case can have up to 7 case fans and it comes with 2 fans. I included 4 case fans in case you want to replace those preinstalled fans. Just note that motherboard has only 4 case fan headers (can plug only 4 case fans to it) So you have 3 choices.

  1. Uninstall the fans that come with the case and replace them with 4 of Noctua fans

  2. Buy only 2 Noctua fans and keep 2 fans that come with the case.

  3. If you want to use all 6 case fans (2 preinstalled, 6 Noctua) buy fan splitters like these ones:


You mount NH-D15 to the motherboard and on the CPU and it has it's own fan header, so fans on it don't count as a case fans.

It's for the M2 cooler per p.14.

If you're not using an M2 drive, then you can disconnect that and plug your fan in there. If you are using an M2, then you'll need to buy a splitter cable so you can run both case fans off of the sys_fan1 header pin.

(Yeah, that other USB cable is for RGB, I think.)

You can buy a fan splitter on Amazon for less then 10$, it takes 1 header and turns it into two This one would work for that

r/pcmasterrace • comment

You never told me if the fan is already on or not.

But besides that if there are more fans than headers you can either get a fan splitter like this or get a fan hub.

Also, is it better to get deep cool splitter too since I'm getting a deep cool fans? thanks

If you can't daisy chain the fans themselves you can get a splitter like this one.

Just use some fan splitters theyre pretty cheap and work just fine because the power that comes out of the fan headers is more than enough to power two fans. I linked the ones I personally use right here

You can get get pwm splitters like this if you don't have enough fan headers on your motherboard. I would not recommend putting more than two fans on one header. I have 2 120mm fans on each header of my motherboard.

Could get just 1 to 2 fan splitter for your two front fans from one system fan header. Exhaust fan with the other system fan header. Fan hub usually have 6 fan ports if you are trying to add more fans. https://www.amazon.com/dp/B01EF9OI0O/ref=cm_sw_r_cp_api_i_wSqLFbM9JS1R6

Any 4 or 3 pin splitter will work fine. Make sure you have the headers set to voltage or DC mode in the bios so you can control their speed at least a little bit to keep them quieter. I personally used these splitters and they work fine and are cheap. https://www.amazon.com/JBtek-Black-Sleeved-Splitter-Converter/dp/B01EF9OI0O
