Yep! The 43mm they quote is actually so there is sufficient room to between the RAM and cooler to detach and reattach the frame wire that fastens the lower 92mm fan to the cooler. In reality, it is more like 46-47mm. Further, you can actually just leave the fan attached in the first place and never even have to touch the 92mm fan’s metal wire mounting frame at all. Silly me, however, made the mistake of leaving the stock fan on and not putting on the new fan that I had purchased until after mounting the cooler. Silly how things work. Fortunately, it was doable... but let me tell you, twisting, reorienting and sliding the wire frame within that 2-3mm crevice between the cooler fins and the top of the RAM heatsink is not unlike some of those boondoggle puzzles that unlock only with just the right slight of hand. However, to repeat, putting the right fan on first before mounting, I personally guarantee that the NH-L12 and Trident Z DDR4 memory are completely physically compatible with one another.
