    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 years in use

    After 4 years, the cooling capacity has declined.

    I had to replace the liquid and clean the copper fins. Despite this problem, I am satisfied with the cooling performance of my use.

    The pump stopped working just after 3 years

    The pump stopped working after 3 years and a few months, the warranty is 3 months. Expensive component that goes to waste, I have previously had other AIOs from other brands that have worked for more than 6 years without problems. I will never buy an NZXT AIO again

    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. ​​​​​​​​​​​​​​​​
