總結:看完Intel i9-9900K各位有什麼感覺呢，先來講散熱部分，改用釺焊金屬材料導熱確實在溫度表現上有明顯差異，有稍微觀察了一下超頻5.1GHz情況下的溫度狀況，最高溫度都有機會碰到9X度，平均溫度可以在85~90之間，而且只是用240mm一體式水冷，如果用360mm或是DIY水冷溫度可以再更低一點，效能表現部分也相當符合期待，預設表現就相當亮眼，超頻後表現更是優異，超頻極限頻率這次就沒有測試，不過以目前來看要上5.1GHz可以說是相當輕鬆容易，超頻上5.1GHz後CINEBENCH R15分數已經可看到X299平台的i9-7900X車尾燈，若可超頻至更高頻率，相信表現會更為出色，這次搭配華擎ASRock Z390 Taichi，紮實用料就算搭配9900K超頻也是沒問題且輕鬆，穩定度也相當不錯，記憶體可超頻至DDR4-4000，頻寬表現讀取與寫入皆有59000~60000MB/s，有效能優異且可以超頻的處理器也要有用料與超頻穩定性不錯的主機板搭配，這次的Intel i9-9900K介紹就先到這邊告一段落。
