I'm starting a new thread on the 290rlt fridge fan noise because the original one started by Jim Hawthorne on 5/1/2012 is no longer active and I have a question.
I am starting my first summer with my 290RLT and experiencing the same loud refrig fan noise. The fan I found on OutletPC has the following specs and wanted to know if this is the same fan that Jim installed. The CFM is around 32 which seems low compared to some of the Sunon's. The fan speed seems lower also so I'm not sure if this is the same fan Jim installed.
I'm hoping Jim is still on this forum and could respond to this post.
Hi! This is Jim!
Please note that the 2 fans I installed were the "Silent 9 TC" version; these move about 38 CFM each. The "TC" stands for "Thermal Control" and makes the fan run between 900-2000 rpm, depending on the temperature inside the enclosure. The basic "Silent 9" runs at 1500 rpm and moves about 32 CFM, so I recommend the "TC" version.
My original Sunon moved about 70 CFM, and the 2 Silent 9TC versions together move about 80 CFM. The actual volume of the enclosure behind the fridge is approximately 6 cubic feet, so I feel there is more than sufficient air exchange.
I chose GELID fans as I found that they always ran flawlessly while cooling computer cases, router arrays and server racks, and never had a failure. But there are other manufacturers that also make quiet fans.
I have had no problems with the fans and really appreciate the quiet!
If you can wriggle a camera down into the enclosure and get a photo of the existing noisy fan, you can then go get the specs on it before you buy a replacement to make sure the replacement(s) will move enough air!
