If you have wondered whats in a 22L Brass monkey fridge from Jaycar? Well heres a few pictures. What i liked about these was price 3 yr replacement warranty. They are fairly easy to access most of its parts, & does what its suposed to do. The control buttons are nota physical switch as such but sense the placement of your finger. If the cover of the control is removed, you need to make sure the springs are set in place correctly, otherwise they dont work.

Is that a 92mm fan? I replaced the 92mm fan with a Noctua 120mm industrial fan. Once one has pulled these things apart you will be happy to do again to clean the dust out, including wiping the underside of the fan blades.

I didnt bother to measure the fan. To remove the cover over the control panel i used a thin old knife ( also used for spliting gearboxes that use a silicon sealer) Just start at one end & work your way along this side, theres only a couple clips holding it in.
