做多少事,說多少話。
滄者極限 - 全漢FSP Hydro X(黑爵士X)550W開箱測試

"另一側是噪音曲線與轉換效率,電源負載在70%以下是維持低轉,約700RPM,噪音值低
於15dBA,相當不明顯,超過70%才會提高轉速,最高約1100RPM,噪音值約在23dBA。"

"側面有產品規格、風扇噪音圖及電源轉換效率圖,可以看出黑爵士X 550W 在負載70%之
前風扇都維持600RPM 15dB左右噪音,相當安靜,而就算到100%負載風扇轉速也在1200RPM
以內,噪音表現也不到25dB,電源轉換率部分在50%負載下效率達90%以上,並且貼有代理
商視博通的貼紙。"

What gave me lots of trouble during testing is its really weird fan profile
that is due to a poorly placed thermistor that provides temperature
information to the fan-control circuit.
因為提供溫度數據給風扇控速電路的感測器擺的位置不好,在測試過程中,奇怪的轉速配置造成我很多困擾。
FSP attached this thermistor to the main transformer instead of finding a way
to monitor the +12V FETs' temperatures, which results in a lousy fan profile
that has the fan run at an almost steady 1200 RPM throughout the PSU's entire
operating range at normal operating temperatures.
全漢將感應器貼在主變壓器上面,而不是另外找方法監控12V輸出的電晶體溫度,這糟糕
的風扇轉速配置,造成在風扇常溫下幾乎是工作在1200RPM。
To make things worse, the fan also spins at close to 1200 RPM at light loads
where the HGX450's fan only spins at 700 RPM.
更糟糕的是,在輕載時風扇轉速也是工作在 1200 RPM上下,其中HGX450的轉速只落在700 RPM左右。 (這段不確定意思)
I received two HGX550 samples, and the fan behaved the same with both, which
suggests that FSP should look into this matter as soon as possible.
當我收到 HGX550 送測品時,風扇測試的結果也是相同,建議全漢應該盡快針對這個問題
做出調整。
With a proper fan profile and a much lower price close to $70, I would have
no problem whatsoever in recommending this unit since it uses reliable
quality components and performs well overall.
在合適的風扇轉速配置與價格之下,推薦這顆可靠品質好的電供,倒不是問題。
Good:
Full power at 46°C
Efficient
Hold-up time
High quality electrolytic caps
4x PCIe connectors
Very efficient 5VSB rail
Compact dimensions
Warranty
Nice looks
優:
全載時46度C
高效率
高保持時間
高品質電容
四個PCIE接頭
本體尺寸緊湊
5VSB輸出相當優異
保固
外觀好看
Bad:
Very high MSRP
The fan's minimum RPM should be much lower
The fan-control thermistor is poorly placed
劣;
建議售價過高(實際售價合理)
風扇最轉速應該能設計的更低
風扇控速的溫度感測器擺放的位置不好
懶人包:
一般消費者看圖說故事,HGX 風扇只工作在600~1200RPM,低轉又噪音的好夥伴!
實際測試,風扇轉速從1200RPM起跳,全載時落在1600轉左右,應對風扇轉速做出調整。
