Well I finally got around to installing one of these. Now the the only way I can tell the refrigerator is running is to check the amp meter

It was a perfect fit into the shroud of my system. I did notice that the number of blades are the same, but the shape is a lot different.

Re: Condensor fan speed control?

I don't know what a Quiet X fan is, but often you can get a squirrel cage blower that will move quite a bit of air and do so very quietly, maybe find one of those?
If you reduce air flow, you will increase pressure in the Condenser, reduce efficiency and cooling capacity, and I would assume life of the components, particularly the compressor, and isn't the electronic controller temp sensitive?
Need a HVAC expert to chime in.

These fans need to fit a specifically-sized shroud, so a squirrel cage blower is out. Besides, the manufacturers ship the units with a computer case fan for this application. The SilenX is just a higher-quality case fan than the cheap ones shipped with the unit. On our unit, the SilenX provides higher airflow. No need for a HVAC expert on this - it is pretty simple stuff.

low cost risk..

I was responding to this, where he says power draw and airflow are reduced from the stock fan. A reduction is airflow will result in a build up of both heat and pressure, assuming the stock fan wasn't over sized of course.

Re: Condensor fan speed control?

We knew it moved less air and drew less current when we started this. The difference us slight but noticeable.

Re: Condensor fan speed control?

Airflow probably isn't a problem except for when the system is running at capacity at the high design air temp. This is very very rare.

Mark, what db level would you consider silent/noisy for a fan?
Going through similar just now and would appreciate some advice before visiting a computer shop.
