    Snaped nut on the CPU housing...Grrr

    Hello i bought from Amazon for my new Rig...

    When installing the CPU cooler, the marked 3 Nit broke. I did not even use too much pressure.

    I have managed to still work with only 3 nut, but I would like to know where I could get a replacement.

    Regards

    Kevin

    4 Jahre In Benutzung

    Nach 4 Jahren hat die Kühlleistung nachgelassen.

    Ich musste die Flüssigkeit erneuern und die Kupfer Lamellen reinigen. Trotz dieser Problematik bin ich mit der Kühlleistung in meinem Gebrauch zufrieden.

    La bomba dejó de funcionar justo a los 3 años

    La bomba ha dejado de funcionar a los 3 años y pocos meses, la garantía es de 3 meses. Componente caro que va a la basura, anteriormente he tenido otras AIO de otras marcas que han funcionado durante más de 6 años sin problemas. No volveré a comprar una AIO de NZXT

    Fan rgb looks off

    I bought Karen 240mm aio and I'm really disappointed that it has different fan. Cause I also bought h9 elite case. The fans on the aio don't look good and the colours are bad compared to the case fans and it's really sad to see two different types of fans and they don't even have same rgb colours. The aio fans are shallow and case fans are deeper.

    My issue is not the

    My issue is not the graphics card, but rather that my computer wouldn't turn on when I received it. After calling technical support and attempting multiple troubleshooting steps, they ultimately told me the issue couldn't be fixed remotely and promised to send additional instructions which never arrived. I ended up disassembling the computer myself and discovered the problem: the AIO wasn't seated properly and the power cables on the top of the motherboard weren't fully connected. ​​​​​​​​​​​​​​​​
