I've used several different versions of these Corsair coolers and they all work great. I regularly get 6th and 7th gen Intel i7 and i5 processors at at least 4.8GHz, 100% stress tested and stable. Typical peak temperatures after 24 hours at 100% load are in the upper 60 degrees Celsius range. Now the downside, and it's important. Check the motherboard for capacitors located in this box which has holes in it to support the heatsink. If you have condensers in that range and have LOTS of megabytes, these coolers will NOT install properly without modification. Note that these cores are heated by 10 degrees or more. Now this deficiency can be fixed if you are not very proficient in building a PC. All you have to do is grind about 0.01" from the edge protruding from the capacitors. It's such a minor glitch as to be ridiculous, but it's there, and if you're having overheating issues with these Corsair products, here's why.
