GTX480雙螢幕運作下存在功耗過高的問題
詳情看測試
http://www.legitreviews.com/article/1258/15/ GTX480多接一台螢幕，閒置時耗電整整多出80W，溫度瞬間來到90度 相較於GTX285 HD5870都概略只有上升40W 測試的機殼是Corsair 800D，所以在一般的機殼下溫度可能更可觀 NV的回應是 -- "We are currently keeping memory clock high to avoid some screen flicker when changing power states, so for now we are running higher idle power in dual-screen setups. Not sure when/if this will be changed. Also note we're trading off temps for acoustic quality at idle. We could ratchet down the temp, but need to turn up the fan to do so. Our fan control is set to not start increasing fan until we're up near the 80's, so the higher temp is actually by design to keep the acoustics lower." - NVIDIA PR -- 大易就是為了避免電源狀態改變時，時脈跳動導致螢幕閃爍，所以顯卡會保持在較高的頻率 |

我看nv也是一個頭抱著燒了
 風扇靜=>溫度高；溫度低=>風扇吵… 看來就像父子騎驢，怎麼做都會被罵吧， 功耗高光是散熱這點就真的很頭大了  |

司儀(達文西):待機到90度是不可以原諒的
不過看在有創意，時間到以前再做一塊新的吧 |

看來nv為了使待機安靜一些,不想提高風扇轉速,
只能讓溫度飆高,而他們也無法確定此種情況會獲得改善, 不過gpu來到90度,散熱器的熱量仍能經由熱傳導讓機殼內溫度升高, 所有溫控風扇都會受影響,能不能獲得安靜還是未知數, "功耗一高,什麼問題都來", 問題不在高功耗,而在其所衍生帶來的問題一堆, 也讓driver team傷腦筋... |

RMA處理人員可能會收到待機就把顯卡燒壞的字條還有還要面對還不出卡的窘境，然後直接升級費米II。
想太多了
