外國 Youtuber The Tech Buyer's Guru 評測 Arctic P12 vs P14 散熱與靜音表現,
結論:6個 12 公分扇表現比較好
重點摘要
1. 最高轉速下,14cm 散熱能力強,同時也比較吵。
2. 只放三個風扇的情況下,1前1上1後對 CPU 散熱有利,2前1後對 GPU 有利。
3. 放三或四個風扇時,14cm 在 音量限定 35dB 下溫度表現比 12cm 好。
4. 對 CPU 來說,前置下三對散熱沒幫助只會更吵,但是對 GPU 來說,前置下三對溫度影響很大。
5. 同音量下,GPU 溫度表現 3前2上1後六個 12 cm > 3前1上1後五個 12cm > 2前2上1後五個14cm。
主要限定條件
1. 不同機殼,不同型號風扇,或加入水冷結果可能不同。
2. 以上測試都讓每個風扇轉速一樣。不排除在允許個別風扇轉速不同時,結果有更多變化。
討論
單獨比較風扇時,一般認為14cm扇比12cm扇更安靜或者散熱更強,不過顯然裝在機殼上要考慮的變因更多。
如果能在前板最下面加上一個風扇,對 GPU 散熱的影響會大過12cm 與 14cm的差距。
這個位置看起來好像主要是吹到電供,實際上卻大大左右顯卡散熱的能力。
至於大機殼裝上六個 14cm 表現會不會更好?不一定,有時候機殼大反而對散熱不利。
