    Alright guys so it's been awhile since I've done a full build. Parts are in my sig, I'm finally getting around to building this thing. I have a small issue that I can't seem to figure out. So the fans that come with my AIO cooler are Noctua F12's and I purchased another two for a push/pull set-up. The issue I have is that these two pair of fans are rated for different voltages.

    Fans that came with the cooler: NF-F12, 0.1A, 1.2W

    Fans from Amazon: NF-F12, 0.05A, 0.6W

    Will I have any issues running these fans together? My plan was to install all four connecting to the main pump unit with two Y fan splitters. However I'm afraid because the fans are running at difference speeds it'll create extra noise with turbulence. Is there a way I can get these fans to run at the same speed? Or should I just order another pair from Amazon?

    You say the fans are rated for different voltages but the info you supplied tells a different story. A 0.1A, 1.2W (@12v) fan will draw 0.05A, 0.6W if run at 6v, which is an option. It's possible that the fans that came with the cooler are rated for double the speed as the ones you got on Amazon, but if they both have the same model number that would surprise me.

    Can you post a link to the fans you bought from Amazon? I'm guessing you got the right fans and the product listing is just funky. Does the model number match? How about the info on the stickers located on the fan hubs?

    Does the sticker have anything else, like RPM information? They'll all be 12v. If that's the case, then it seems like maybe the Ryujin came with the "industrial" high-speed Noctuas.

    Edit: just checked the Asus product page and yep, they are the Noctua iPPC-2000 PWM fans. Maybe see if you can get a match on that part number on Amazon and exchange the ones you bought.

    Edit edit: here you go! Noctua NF-F12 iPPC 2000 PWM, 4-Pin, Heavy Duty Cooling Fan with 2000RPM (120mm, Black) https://www.amazon.com/dp/B00KFCR5BA/

    Thanks! I think I'll stick with the non-industrial ones since they look quieter.

    Hard to go wrong with Noctua fans, excellent build quality. I personally would have gone with VanGoghComplex's recommendation. Get a faster fan and use the motherboard's fan speed control to keep them quiet. That way you have some extra speed in the tank if you need it sometime.
