Wine chiller exterior fan repair

I have two Edgestar counter-height wine chillers. One is filled with wine and the other I use like a root cellar, holding onions, tomatoes, potatoes, and other things that like it cool but not cold like chocolate. I've had them for 7 or 8 years, which I think is longer than they're intended to last. I've replaced an inside fan, a Peltier chiller unit and a control board .

One of them starting making an awful noise, coming from the exterior fans. Well, they're exterior to the chilled box; they're still behind the back panel, which just requires removing a pile of screws. Note that there are 3 screws tucked up in the recessed part of the back panel!

There is a possibility that a thorough cleaning of the fans might have solved the problem, but they're inexpensive computer-type fans and I figured I'd just replace them, since they were 7 or 8 years old, about as long as they typically last.

Here's one of the two old fans, removed. It's listed as a Toyon Model TD9025LS, 12 VDC, 0.16A (1.92W) fan. I found a replacement on Amazon, but the reviews were mixed, and it was a more expensive than what I ended up getting.

I got two Sunon 92mm x 92mm x 25mm, 12 VDC, 1.3W, 39.5 CFM, 2400 RPM, 28 dB fans for $ 2.71 each from Digi-Key !

These fit perfectly and work well, but they're a little bit noisier than the correctly working original fans. There's another one that's 28.1 CFM, 1700 RPM, 17.7 dB that's a little more expensive at $ 4.41 that might be better if your chiller in a noise sensitive environment. The higher air flow in the cheaper fan should help, particularly when it's warm in the room, however.

The fan bracket is held to the chiller cabinet with 2 screws. Here are the new fans mounted in the bracket. Make sure you orient them correctly - the air should blow up, into the heat sink. Note that the way the bracket is sitting here, it's upside down, so the fan flow is down when you're looking at it this way!

The only other thing to do is make the power connections to the fans. I cut the old fan wires and used little gray wire nuts.

That's it!
