I ordered this same cooler from Newegg, However I found the same cooler at a location close to me for even cheaper, so I decided to buy it at Bestbuy. The installation process was easy, however the included guide was basically useless it's all pictures no description on how or what you're doing, just visual guides, instead I just found a tutorial on YouTube that helped a lot more and was able to install it way easier that way. I installed it on an i5 8600k (LGA 1151) it came with thermal compound as most coolers do, I already had some good thermal compound but I'm sure the included thermal paste would have worked just fine. It performs a lot better than my stock cooler, My stock cooler was far too loud and I think the bearings were going out as it made a mild but audible whining and ticking sound when it reached it's max speeds, with the stock cooler at idle my temps were 55°-65° under load they'd reach as high as 85° with this cooler master cooler the temps were cut in half at idle, now my temps at idle are 25°-30° under load temps are at 55°-65°, all in all I'm really happy with this air cooler the included rgb controller is simple to use although it's kinda basic, but it's nice to have as my motherboard unfortunately does not have an RGB header. The cable that connects the fan to the rgb controller was long enough that I had no issue running it up and behind my back panel and out of sight. The cooler fan itself is super quite. It's a relief compared to my old stock cooler. All in all this is a great cooler, I'll most likely buy this for future builds and replace any included stock heatsinks with this instead. 10/10
