Question Fan connections. So confused. lol It was so much simpler back in the day when it was all 3 pin, no rgb, and no AIO.

I'm getting lost on how to connect my cooling setup to the mobo.
My case is the Corsair 750d airflow edition.

These 3 will be replacing my case's 2 front intake fans.

My AIO will exhaust out the top https://www.amazon.com/gp/product/B07WSDLRVP/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
and will be a push pull with the stock 2 AIO fans and 2

And finally 1 https://www.amazon.com/gp/product/B00KFCRF1A/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
exhaust in the back.
So a total of 8 fans. 3 with rgb options. And the AIO connections.
Would like to control the 3 rgb with the Asrock Polychrome Sync and not the Thermaltake argb controller.

Connected to an asrock z490 taichi mobo.

What should go where exactly? This is my first build. I got it all figured out except this now. lol Oh and the more advanced ins and outs of the UEFI, but I'll cross that bridge when I come to it. Mainly I'm having trouble becuase I can't find where it shows how many volts the standard 4 pin fan headers can handle if I wanted to plug more than one into it with some splitters. The mobo manual only gives voltages for a couple of the connectors.


lol And while you're at it do you have any good book recommendations to treat impulse buying? :ROFLMAO:
Thanks in advance
 
The setup should be very straightforward.

You can connect all three of the Thermaltake RGB fans to one 4 pin motherboard header and control RGB from the controller provided or connect directly to the motherboard 3 pin ARGB header for motherboard control of ARGB.

The 3 Thermaltake Fans to the CHA_FAN6WP header.

The Pump/Power from the Arctic Freezer AIO to CPU_FAN2WP_3A header.
The 2 Arctic Freezer Fans to the CPU_FAN1 header

The 2 Noctua fans which will be in push pull on the AIO will connect to a splitter so two into one connecting to the CHA_FAN5WP header.

The rear fan can connect to the CHA_FAN1WP header in the middle of the board.

Control all via BIOS at quiet or normal mode and they will automatically ramp up when needed under load.

Just got the arctic yesterday. Looks like the pump and fans are all powered off of 1 4 pin header. Going to RMA the thermaltakes when they get here. Decided I don't want any RGB flashing at me despite how neat the asrock polychrome can make them.

So instead my new set up this.
The push pull AIO will be mounted in front as an intake which according to this should be plugged into the CPU fan header which on my board will be CPU_Fan1

The 2 Noctua 120mm on the AIO run with a Y splitter to whichever header is reachable.
Another 2 of those same 120mm as intakes in the bottom with Y splitter to whichever header is reachable.

4 140mm as exhaust, 1 rear and 3 top.

I have a question is about amps now. On Noctua's site they are using metric. Am I correct in assuming I can use metric's comma in place of American decimal point? Or vise versa I should say. Each 140mm is rated at ,13A. So that would be .52A in American, right? Which would be well under 1 amp so I can use a 4 way splitter to connect all 4 exhaust to 1 header which will make setting their speed in bios a lot easier since I want them all to run at the same speed?

Final question. Does bios make it simple to see which header is which? Like will it be listed as the MOBO manual does such as CHA_FAN3/WP?
 
Confused on the Amperage question but in general you should be able to run 3 fans of one header. Your motherboard should have an amp reading for each header but then it gets confusing as fan manufactures have there own readings and the whole metric versus imperial crud suddenly comes into play!

So for your AIO and the 4 fans in push pull, use the bottom right fan headers with 2 fans on each header so headers:

Pump
CPU_FAN1

AIO Push/Pull
CHA_FAN6/WP
CHA_FAN3_WP

Rear Fan
CHA_FAN1WP

Three top fans
CPU_FAN2/WP_3A which should have more than enough for the 3 fans

Although do not worry, just test yourself as to what works best.

As to the BIOS settings for fan control. Yes it is fairly straight forward though I would avoid individual set fan curves and just use the presets. Quiet and Normal...I go Quiet mode and as the temps rise it automatically adjust the fans to ramp up...

I shot a message over to Noctua to ask about how they rate their fans. The comma is throwing me. They rate their fans as 0,13A each. They're an Austrian company and use metric unlike us dumb Americans. :rolleyes: I mean heaven forbid we use a system that's ten zillion times easier to use. (If we learn it to begin with anyways) I know it's not that big of a deal if I can;t run all 4 together with a splitter, but running all 4 together is kinda like cable management, but for bios. :)
Thanks again
