Review on NZXT Kraken Z73 360Mm Customizable Computer Components by Anthony Mayes

is quiet, it's dead quiet. Fans only run at 375rpm, 3950X idle at 37oC, light load at 48oC, full load at 60oC (even without thermal paste, wait for Artic MX-4, it should drop the board a few more degrees). didn't bother the DDR4 slot on my X570 Aorus Ultra mobo - AM4 brackets included - Easy to install brackets, screws. Cons: - Paper instructions are pretty primitive. I was expecting a more detailed guide for the $180 product. The instructions in the manuals are incomplete: I spent hours trying to figure out why the fan is running 100% until I read an online PDF manual and found that I didn't need to connect SATA power (yes, if you connect a SATA connection, the fans always run at 100%). Plug the 4-pin X73 fan headers into a PWM hub or motherboard and have the fan speed controlled. RPM straight down from 2400rpm to 375rpm, noise from 56db (audible noise) to 36db (very quiet) Notes: Here is a diagram (at least to get it working with the Aorus Ultra X570) 4 pin motherboard connectors <-- -> 3-pin PWM hub connectors <----> 4-pin AOI cooler fan connectors (SATA not required). Do not connect SATA if your motherboard or PWM hub can already supply enough voltage.
