症狀
當作業系統 （OS） 閒置時，配置低瓦數處理器的伺服器可能會看起來很熱。
原因
標準散熱器的散熱特性不如高效能散熱器。這就是為什麼它們嚴格限制在低瓦數的處理器上。
解析度
此為設計運作方式。
較低瓦數 CPU 會隨附標準散熱器。高效能散熱器不適用於具備低瓦數 CPU 的系統。
安裝與維修手冊 （ISM） 根據瓦數列出 CPU 至散熱器的輪廓。
所有標準散熱器的設計均可在負載沉重時，為處理器提供足夠的散熱能力。
預計在空閒時間會遇到更高的溫度。這不是故障或缺陷。
閒置時的處理器溫度可能無法達到 CPU 目標溫度，以在閒置期間觸發高風扇輸出。CPU 溫度符合規格。
如果習慣使用高瓦數 CPU 和高效能散熱器，則可能會認為此瓦數很高。這些 CPU 溫度符合規格。
這適用於所有 AMD 和 Intel 處理器，無論其型號為何。
如果考慮散熱，可在 iDRAC UI 中修改散熱回應和風扇調整。
- 散熱設定檔最佳化 -允許多個設置。最大效能可在閒置時提供更高的風扇速度。
- 風扇速度偏移 - 可讓風扇速度比基準風扇速度增加 （按偏移百分比值）。
- 閾值 - 可使用此選項設定最低風扇速度。

這些選項可讓使用者自訂調整散熱，以降低處理器閒置時的高溫。如需詳細資訊，請參閱 iDRAC9 使用者指南，以瞭解如何使用 iDRAC Web 介面修改散熱設定。
