I recently purchased the new EK MLC 360 Radiator Core and have been running it for the last week. I painted it white to match the my color scheme. I didn't like the CPU block that you could buy with it so I purchased the quick disconnects and made my own using XSPC waterblock.
Excuse the photos I don't have any official ones yet, but the previous build with the NZXT Kraken x62 can be seen here:
EK is definitely louder than the Kraken x62, but I have my fan profiles set somewhat aggressive. I don't mind a little extra noise since I have a 24 port switch behind me that is louder than anything else in the office. I'm running a 6950X @ 4Ghz 1.3v. I keep it about 72F in the office/homelab and the the Kraken was topping out at 68C, the EK Radiator/pump /w XSPC waterblock tops out at 55-58 on Prime95. I'm using liquid metal for my thermal compound with the EK setup, I used MX-4 compound with the Kraken x62.
Kraken idled around 35-37, EK idles around 28C. Keep in mind the rad on the EK is also a 360 vs the Kraken's 280. Shipping on the EK was very expensive, at the time I couldnt find any stores that sold it yet, I think it was over $50 bucks cause it shipped directly from EK. Also if you want to use your own waterblock, you'll need https://www.ekwb.com/shop/ek-qdc-10mm-gray and some of their coolant, unless you plan to completely remove the tubes that come with the EK radiator and use your own, but I've heard that it was a PIA. I stuck with the QD for easier maintenance.
