    My favorite CPU cooler. Ever!

    My favorite CPU cooler. Ever!
    This thing is absolutely stunning. It's seriously the best looking CPU cooler I've ever seen and it truly becomes a standout piece within your build. It just looks super premium, classy, elegant, and powerful.The performance of this cooler matches it's insanely good looks. I tested this cooler on my i9-12900K with the Thermalright contact frame. I had a Noctua NH-D15 previously before upgrading to this, so this cooler had an insanely tough competitor.I found that, in any general load, the Dark Rock Elite performs roughly 2-4C better than my NH-D15. So yeah, it's definitely utilizing it's faster fans and extra heat pipe to one up the NH-D15. However, what truly stands out are the noise levels. The Dark Rock Elite sounds the same running at 2,000 RPM as the Noctua does running at 1,500 RPM. It's basically inaudible at anything under 1,600 RPM. I'm genuinely blown away (pun intended) as to how quiet this cooler is.

    This is probably the best air cooler you can get for money!

    I rebuilt my son's system from an AIO to this cooler because of issues the AIO had. I have the Threadripper version in my workstation and knew what I was getting into. A little anecdote: My son's PC case was starved for fresh air due to stupid design choices. I remedied this with a MashifyC from Fractal Design. When a software issue arose (bloatware from the Mainboard), we felt the glass was hot right about the cooler. Perplexed, I wondered how the chassis could heat up despite the great airflow design. I opened the chassis and it was cool inside. This is when I realized the CPU cooler is so good ( and large) that it even transferred heat to the glass 1/2 in away!

    Pros:
    - Best air CPU cooler you can get
    - no LED shenanigans
    - Massive fin stacks and many heat pipes
    - low noise fans
    - pretty
    - highly precisely machined copper heat conductor - works well with liquid metal instead of thermal paste
    - a cool screwdriver is included

    Cons:
    - If you never built a PC, you may want to look for a cooler that's easier to install. I build my own rigs since almost 3 decades - I did not mind, but your mileage may vary
    - Massive - you need a good quality Mainboard to not flex under the weight
    - no LED for those who look for those looks - and it will block some RAM slots from sight if you have that as LED
    - Some larger RAM modules will not work with this one
    - Some PC cases may be too slim to work with this one

    Hints and recommendations:
    - Check clearances so that it fits into your chassis and does not interfere with high RAM. The RAM does not need to be low profile, but some really large RAM modules - especially with LED may interfere - and LED would get covered up
    - Do not transport your tower upright with the cooler hanging like this on the Mainboard's side - lay it down so the Mainboard is on the bottom instead
    - the frontal cooler is somewhat finicky to install when RAM interferes to some degree - and this will increase the overall height, thus chassis room needed. The Fractal Design MashifyC DOES work with RAM that requires a shifted front fan on this cooler. I had to do this and it works perfectly.

    Last thoughts:
    Now, I knew all the Cons of this cooler going into this upgrade. I did choose cooler capacity over RGB loos my son would have chosen and I ordered RGB fans for his PC for the case to make up for it. I know from experience, this cooler will beat many others I've seen and I do understand why it is so hard to install: It's a trade-off for its size. The choice BeQuiet! had was to either use the space they have to work with to put more cooling it or to make it easier to install, but not both. They chose what is important and its primary purpose: Cooling!

    Would I buy it again? Absolutely! Actually, I am currently running the stock Wraith on my secondary system and will probably replace it with another one of these ones. It looks beefy, is beefy, and has a beefy cooling capacity.

    Installing this cooler was a breeze (no pun intended... get it, cause it's a fan heatsink?). I really like the screw-less fan installation design of this cooler. The little wire brackets that hold the fan in place are pretty genius. I don't know if that's standard for coolers these days, this is the first new cooler I've bought in like 10 years. Switched from AIO water cooler that was a few years past its expiration date, and I don't think I'll be going back to water cooling any time soon while this product line exists. Liquid cooling is neat, but this is just easier to deal with, frees up case fan slots and is just as efficient and quiet as a liquid cooler.
