I use this for gaming (165 Hz 2560x1440 monitor), work(clerical/translation), videos & music. I really like the cpu cooler.
edit 6/23/18: I have begun to tweak/overclock the CPU through the bios as well as modify the fan curve of the CPU cooler's two fans. The idle temperatures are a little higher (from 27 to 35 degrees celsius) but under load temperatures (while playing Overwatch) have been reduced a little (from 66 to 64 degrees celsius). Will continue to stress test and keep an eye out for problems.
Definitely an amazing CPU cooler. It was a fun experience to assemble and install onto the CPU and motherboard. I had previously been considering the Dark Rock Pro 4 or Noctua D-15, since my case can't fit a 240mm liquid CPU cooler. However, after some investigation, my case also did not have the height clearance for those two coolers. Then I saw a few suggestions to look into the Thermalright Le Grand Macho RT. This one definitely caught my eye.
Although it barely clears the case, it stands out in terms of quietness and cooling capacity. For anyone looking to pick up the Le Grand Macho RT, please remember to check dimensions to insure that this item will fit in your build. I had purchased a fan duct from Thermalright, reading about how it could lower CPU temps by 5-10 degrees celsius, but unfortunately my case was too small and the duct could not fit in between the CPU cooler and the rear exhaust fan. Also, since I first installed the CPU cooler on the motherboard outside of the case, I had to do some cable management and rearrange the rear top exhaust fan to outside of the case to allow for the installation of the motherboard with the CPU cooler. Right now my CPU is idling at 27-28 degrees celsius with the CPU cooler fan barely spinning.
Assembly of CPU cooler and installation of motherboard, CPU, CPU cooler, RAM, wires/cables, and GPU took about 3 hours (with breaks). I am very satisfied with the results.
