LG PF1500 Largo Fan Adapter 60mm
Description
My LG Largo / PF1500-EU works fine for several years now, but I'm never using the lower ECO modes for a brighter image, because they are too loud. To achieve more silent ECO modes, it's possible to upgrade from the internal 2x 40mm fans to 2x 60mm fans on the outside. I've created a customized backplate to attach the fan mount. The backplate is quite close to the original model and fits in perfectly for me. There are two tubes directly on the backplate going into the device to guide the air onto the heatsinks. The second part, the fan mount itself, is connected with the backplate inside the tubes with 6 clips. Watch out for the tight spots on the plugs. There is just enough space for the power plug and I guess you'd need a 90° adapter for the HDMI port if you have to use it. The clips are quite fragile, they fit in once but taking it apart again could easily break the clips. Print with supports everywhere above 50° for the space under the clips and inside the clips for durable teeth. There are small plates below the clips, because I had some issues with support structures falling down. I've included a close-to-original backplate without fan mount as well, if anyone needs it. (Doesn't fit with the fan duct) For the fan mod I've chosen Cooltek 60mm silent fans. They are indeed silent but with the current hot summer, the ambiet temp is quite high (33°C) which leads to high temps in ECO mode min (64°C) with 12v fan duty set in the service menu. With lower ambient temps around 27°C, the ECO mode min stays below 60°C, which is fine for me. I've expected more from this mod, but I guess the added distance of 6cm negates the size advantage of the fans in combination with the "silent" power downgrade. Maybe I'm trying other fans or even upgrade to 80mm at some point. The LG Largo / PF1500-EU is definitely still worth it and just came out as V2. Thanks to the guys in the german hifi-forum.de Largo thread for inspiration and service menu description.
