Picture of the mainboard i found at https://ecodrift.ru/2018/11/29/kingsong-ks-18xl-chernoe-na-belom-i-chto-spryatano-vnutri/ In https://forum.electricunicycle.org/topic/15349-can-someone-show-me-a-photo-of-the-ks18xl-motherboard/ "Best" visible on https://eunicycles.eu/en/spare-parts/135-motherboard-ks-18lxl-newest-spec-v13.html Doing a google search for ks18xl board and looking at the pictures maybe leads you even further. Should be a radial radiator - roughly like https://www.mouser.at/ProductDetail/Sunon/MF50151VX-B00U-A99?qs=EU6FO9ffTwfWIV5p3irB3g== As one can guess from the photos the fan is between the four big capacitors and the heatsink - ?with an opening in the heatsink as air input? So you'd need quite exactly the same model, so everything works out... And still some skills to get mouting right. Btw: maybe something got (partially) inside and just touching the rotor blades making the noise!? Or playing roulette inside the fan... Edit: ps: there exist different ks18xl mb versions...

SDmike Posted June 28, 2020 Share Posted June 28, 2020 This is the fan used on my 18l. I believe the 18xl uses the same fan. Part number RG05005HD5. http://www.rdkcooler.com/en/productshow.asp?id=931 1 Quote Link to comment Share on other sites More sharing options...
..... Posted June 10, 2021 Share Posted June 10, 2021 I bet you can get a new fan when you buy a new wheel Seems to me like I wouldnt tackle that for maintenance, as itll put stress on too much stuff and undermine your intentions. If a fan went bad, I'd say the hard way is the only way. Gotta gently pry up some caps and have official chinese wheel glue ready. I dont envy you on wanting to replace that! 1 Quote Link to comment Share on other sites More sharing options...
M640x Posted June 11, 2021 Share Posted June 11, 2021 (edited) Receive my 18XL in a couple more weeks. I'm going to add another fan in the area of the control board. The goal is to "evacuate" hot air around the control board and that compartment. I did this on a control box on my electric truck and it worked out very well for pulling heat out of the box.

Are you having overheat issue? The old 'if it aint broke don't fix it" comes to mind. 2 Quote Link to comment Share on other sites More sharing options...

These are known to run hot "out of the box" as the saying goes. I can see why. There is a very small fan and the inlet is mostly covered by capacitors so I think some of the airflow is blocked. Once the air is pushed past the control board and collects more heat there doesn't appear to be any exit for the hot air. It' appears to be a similar situation to my electric S10 where the heated air just stays inside the "plastic box". The top of the wheel in this case. Of course I'll take a closer look when it's finally shipped. The number that's been quoted has been at least 10 degrees hotter than other wheels. I'll be in AZ soon and the summer temps there is just going to add to the inherent temp issue of this wheel. Think of it as preventative maintenance. It's cool to have another NC guy on here. I grew up in Jacksonville, NC. Edited June 13, 2021 by Senior Coffee Quote Link to comment Share on other sites More sharing options...
Roadpower Posted June 13, 2021 Share Posted June 13, 2021 I just noticed this thread. What is nominal and acceptable hear, how much heat is too much, and can I go by what I see in the EUC World app? Also I almost never hear the fan but I have the Roll NZ cover on it. Quote Link to comment Share on other sites More sharing options...
Meserias Posted June 13, 2021 Share Posted June 13, 2021 this wheel its very quiet unless you are riding over hills with 90 kg or more.... very rarely I heard the ventilator on my wheel.... best stable wheel... 3 Quote Link to comment Share on other sites More sharing options...
..... Posted June 13, 2021 Share Posted June 13, 2021 (edited) I've yet to see any of mine get hot, but I'm also not in the desert, don't weigh much, and don't ride faster than 27mph.. Adding a secondary fan sounds like an easier solution than replacing/upgrading at least. I also run a rollNZ on mine, but again, i dont live in +100F climates.
