Anyone have a fix for the X299 bios concerning fan speeds? Locked at 1480RPM, my Noctuas do 2000RPM and max setting changes nothing.

Need more information. Which BIOS are you on, which Noctua fans are you using, and which fan headers are you using? Can you give me a screenshot of your BIOS with the fan configuration?

X299 M-ATX 2 - Bios is the one before the newest. NF-A12x25 x 3 on CLC 360. Using the splitter from the pump. However, I may return them to amazon anyway, the FLX are cheaper and I get a full refund to my account.

Ah. If you're using the pump to drive the fans, that will probably explain why your fans are running at a lower speed. If you ran them directly off the motherboard, the speed shouldn't be an issue.

Why do they only run the way they do off pump? Will non-pwm do the same of the splitter?

Because the CLC ultimately controls the fans, not the motherboard. The motherboard fan header should be at 100%/Max (as opposed to auto or SMART) to make sure the CLC is recognized and operates properly, but that doesn't really affect the fan speed. You could try adjusting the fans through Flow Control first, if you haven't already, to see if the fan speed will go higher. Otherwise, the motherboard fan headers will recognize the fans and treat them properly. Pretty much all of the fan headers are auto PWM/DC, so they will detect which type it is and set the speed according to PWM or voltage.

So buying the non-pwm version wouldn't make a difference? Was trying to save using more cables, I'll buy some if my idea does not work.

For your EVGA X299 M-ATX 2 you have PWM fans header and CPU1 and CPU2. You can put cooler pump pin on to PWN fan and set 100% speed for pump and those two CPU fan and CPU2 headers you can plug 3 NF-A12x25 pins together on to CPU1 fan header because you have 1 amp per fan headers page 40 therefore your NF-A12x25 draw is 0.14amp that mean you can use 3 x NF-A12x25 fans 0.14amp x 3 = 0.42amp that plenty left for 1 amp. You can use 6 fans split 3 each cpu1 and cpu2 for push and pull for your cooler radiator! Make sure less than 1 Amp is safe! I don't use EVGA Cooler software cos the problem with fans too high loud!! Have a look my post #4 here what I did on my Rig!

Hmm, thought the pump ran at 100% anyway on the CPU headers. I'll mess around and see what happens. I gave up on EVGA software, barely any of them work, Eleet broke a long time ago and flow never opens for me.

Yeah I don't use software because you can use this for changing led setting and Fan curve but it will save setting into pump firmware then no need software after as we have fans control on our motherboard!! Give a go and test! You will happy it more quiet using motherboard fan control rather software!!
