help with first build! fan Xpert 4 and corsair H110i

Okay so this is my first build so I'm bit of a novice but it all went well and is up and running BUT... i have a asus motherboard with 3 fan headers and a corsair h100i with 2 dedicated fan ports, However i want to use the fan xpert software for the complete system and not have two programs (corsair link) monitoring two different areas of fans. is there any way round this?

    with this crappy shinny toy, the only way to control the fans via SW other than corsair link, you need to connect the fans directly to a header on the motherboard. best practice is to do it with spliter so both fans connected to the same header and controlled together.
    BUT, and there is a huge but. The pump speed will not be regulated unless you use the corsair link.
    Next time ask before buying or at least read installation guide of the product you are going to buy

    so if i was to put a spitter into the motherboard, will it be able to draw enough power for both fans and be able to monitor and change the speeds of them both? i guess it'll be shown as a single fan but will the rpms be accurate? secondly the pump speed, does it matter much?
    Thanks for the great advice, i really should've but I'm now out of my returns policy :(

  3. yes, they will report correct speed. splitters usually have only 1 fan wired to report the RPM. since the fans are identical, no problem with that.
    since you are mentioning fan expert 4, i guess you have some asus z270 board which is perfectly capable of running much more than 2 fans on any header.

    pump speed is important as it is affects the flow rate which has to be at least 0.5GPM for adequate cooling under load. In AiOs like this or any other Asetek/CoolIt crap rebranded and sold by EVGA, Corsair, NZXT, Arctitc, TT and others, the pumps are very weak. so in order to keep them quite, they run on low RPM at idle, and very high RPM under load.

    I really appreciate the help I'm learning a lot, although i have another question, should i buy a standard spitter or do i need a certain type?
    also have you got any advice or what'd you do if you was in this situation?

  5. Any splitter with matching pin numbers will work. I use Noctua's since it's kinda nicely sleeved and was cheap and available at the store near my home.
    As for the situation, I'm not using fan expert since in my version it allows to make fan curves based on CPU or MB temperatures only.
    If I remember correctly, fan xpert 4 do allow additional temperatures like GPU, but not sure if the GPU can be anything or just asus made.
    Since you probably would be better to connect the h100i to corsair link for the pump, guess it will be fine to use it for fans as well.
    But it really depends on your config, personal preferences and what corsair link allows you to do.
    There are also additional Corsair Link components that allow monitoring and controlling other components in your system - I wouldn't buy it.

    It's hard to say what i'd do, since it's hard imagine myself buying it and i'm not really budget restricted for my toys.
    So probably i'd find some use for it in other computer (friends, parents, GF etc.) or just selling it. And getting proper liquid cooling in the form of custom loop or at least decently made AiOs like Swiftech H X2 or EK Predator. The later is EOL and supposed to be replaced with new modular kits in the form of EK-MLC sometime this spring

    Yeah I was just looking into the cosair link, I think I'm gonna stick with that for my controls. Would've been nice to have everything in the al suite but tough luck I guess! I'm gonna hold on to this aio in till time calls for me to change it but that probably won't be too long as they are extremely loud! But you sir have been a gold mine thanks for you time and help!!

  7. you are welcome.

    Hint - replacing stock fans with better ones will make it quieter. Though a pair of good fans like Noctua NF-A14 industrialPPC can cost some 50-60$.
    but even corsair's mediocre SP fans would be better and quieter than stock.

    Okay I've spent a while thinking and what do you think about this idea. My motherboard has a aio header on the board, I know I won't be able to control the variable pump speed in fan-expert but I could just have the corsair link for pump speeds then have the two fans radiator fans plugged into my mobo via a spitter into my cpu fan header? My mobo can directly monitor temps of the cpu and would be able to control fan speeds via fan-Xpert. Also I only have 3 pin fans do you think I should invest in having a whole rig of pwm fans?

  9. the AiO header, IFAIR, is just a fan header with enhanced current capability.
    Fan headers on asus boards can be used in both DC (3pin) and PWM (4pin) modes. they (individually) either detect the mode automatically or/and can be manually set to desired mode in BIOS.
    There is nothing wrong with using DC fans.
    Overall, you plan is fine.
