Coolerguys120mm (120 x 120 x 38) High Airflow Waterproof IP67 12V Fan

他のレビューにもありましたが防水でもないし回転数も少ないような違う物が届きました。わざとなのか間違ったのかは不明やけど詐欺まがい？と疑ってしまう。中国なので返品とか手続きが面倒くさそう。ここでは買わない方が無難かな。

Fits perfectly between the winch and the oil cooler. Low current draw. Oil cooler now gets airflow while machine is moving slowly or sitting still. Perfect for my application.

It was crazy loud and spinning so fast I thought it was going to tear itself apart and I guess it probably was. I thought for sure that I ordered a 24v fan, but I guess not. I measured 70 decibels on this thing running 24v, so I'm guessing that their 36 db rating when running the proper voltage is probably accurate. It managed to run for several minutes at 24v before I figured out that it was the wrong voltage fan for my use and shut it off, so I think it is probably very durable. If you need a 12v fan in this size that is 36 db or less, then it's probably a great fan for you. For me though, I just hope I didn't damage my printer mobo. Now I have to cut this thing out and solder an appropriate fan on.

It’s a fan. It blows!

防水でない普通のファンが届いた。しかも4ピンで説明書無し。いい加減な商売。バカにしすぎ。
