Fits Gigabyte Z790 mb
Intel 1700, Gigabyte Z790 S Wifi motherboard. Fit the before mentioned mb without interfering with memory or mb heat sinks. Can use all 4 DIMM slots with the supplied 15mm fan. Can replace the 15mm with a 25mm fan if you are willing to give up the first DIMM slot. I used DGHAOP 4pcs Computer Mainboard CPU Radiator Fan Fixing Clip 12cm - Upper Hook Type, to swap out the 15mm fan for a 25mm fan. My third Thermalright cooler. Con- Finish on the inside curve of the heat pipes is garbage. Can not bee seen mounted. Hope it will not effect performance.

This is it, chief.
Easy to install! Very cost effective! 100% memory clearance! Upgraded from a CM Hyper 212 Black (newest edition, with the smaller fin stack) and it is a very big difference for only $10 (usually less than $10, unless the 212 is on sale.) Much quieter, while maintaining temperatures that are roughly 5-10 degrees cooler on average for most tasks on a Ryzen 7600x. Benchmarking, it gets just as hot. But the boost clocks and voltages are higher, meaning this cooler allows for a lot more head room than the hyper 212 did. If you need an inexpensive, well built, dual tower cooler for gaming tasks and don't wanna worry about RAM clearance or noise, this is it.

Very nice cooler for the money.
As I looked online at cpu coolers, The Thermalright line of coolers seemed to have great reviews all across their line and at very nice prices. Came with all parts to mount to amd or intel. The offset design of this one helps in case of some other item in the way. This extra clearance for memory. High quality fan bearings also. Glad I found this.

Instructions
The product is working great but their instructions are not clear and concise. I had to go between multiple YouTube videos to install the cooler.

Great cooling for low cost
Initially I had the stock AMD cooler any my CPU was reaching 63C idle, yes idle. I thought of getting a more expensive aio cooler but decided to try this one out, I was skeptic at first but after installation I was idling at 37C. Plus it’s generally quiet in normal load, at almost inaudible in idle. I saved a lot by getting this rather than those hundred dollar ones.

Good cooling but bearings wear out in fan
Good cooler with a large footprint. The thin fan started have bearing issues after 5 months. Customer service can be contacted by email and they sent me a new fan. I will update again if the new fan isn't any better.

Great Cooler
I'm running a Ryzen 5 5600 processor in my build and I live in an area where outside temps are averaged 29°C, with the supplied wraith stealth cooler the temps were around 54°C at idle and when playing a game like Marvel Rivals it went above 90°C and throttled. To play I basically had to leave the side of the case open and turn on the AC just to keep the temp around 80-85°C. With the Thermalright Royal Knight 120 SE installed, my idle temps are now around 37°C and when playing Marvel Rivals the temp has yet to cross 70°C, the highest I've observed so far is 67°C. This is also without the side off, AC on solution. The cooler was packaged well protected, I can easily access all my RAM slots without obstructions and it fit within my ATX case just fine but I measured before ordering. installation is easy, the only difficulty i faced was clipping the fans on the heatsink but I was "figuring it out", the examples on their website, YT, etc. are more than enough for this to be a non issue. in the box, I received the heatsink, fans, clips, mounting setups for both AMD and Intel processors and Thermalright TF7 thermal paste. You get everything you need for the installation unless you don't own a screwdriver. One note about my results is that I used Artic MX-6 instead of the TF7 paste because of how highly the brand is praised and I had both. I do not think it would of made a big difference as it's usually just by a couple of degrees. This cooler is probably considered overkill for a 5600 but it was the best cooler that had a delivery date that worked for me at the time and It means that I don't have to consider new cooling if I upgrade.

Excelente calidad/precio
Solo seria mejor si viniera con la pasta pre aplicada, y los ventiladores quizá luego los cambie por unos noctua pero es perfecto por el precio
