streetglide420my 280 clc runs my 9900k at 5.5 ghz just fine direct die cooled it also ran 5.3ghz before the delid just fine. i added more fans for push pull. the water temp will hit aroun 34c gaming sometimes, but its does just fine.
streetglide420it will not work with the stock standoffs for the CLC280. I had to rig my own from the hardware store. I dont personally recommend this because you can over tighten and crack the die. I learned the hard way.
