It continuously reconnecting to the wheel, and beeps won’t stop til i shut the app off via app switcher. Yes, it’s because the last beta.😔 Turn off the auto-torch function in settings. It’s because of this function. We’ll fix it in next beta. Quote Link to comment Share on other sites More sharing options...
Marty Backe Posted October 27, 2019 Share Posted October 27, 2019 On 10/23/2019 at 7:25 PM, erk1024 said: TL;DR Conclusion: I need a new fan. I took the Nikola+ for a ride and got it up to 40 degrees C. I could hear the fan (barely). I rode it at 50kph and the temperature climbed all the way up to 63 degrees C. I stopped and listened with my head right next to the shell. I could hear the fan spinning, but still pretty quiet. Just like the previous ride, this happened right around the 6 mile mark. I rode it a little bit more to push it over 65 degrees, and it tilted back until I was forced to get off. I let it cool off a bit and rode it home at 20kph, watching the temperature. It was around 63 degrees all the way home. For comparison, I took out the Monster V3 and rode it at the same speed on the same route. After 12 miles, I was only able to get it up to 47 degrees C. When I got home, the Monster's fan was much louder than the Nikola+ fan. I could hear it easily without putting my head next to the shell. The Nikola tire is at 50psi, I was riding on flat ground at 20kph, and it couldn't bring down the board temperature from 63 degrees?! That just makes no sense. In Marty's Nikola video, the fan is loud. So ... a defective fan is a pretty good guess. Sorry, I've been away from the Forum for days as I've been leading day long rides around Southern California. I'm not convinced that the Nikola fan is variable speed. I think it's certainly worthwhile trying to get a new fan because when they are running properly there is no doubt that it's running (no need to put your head near the shell). 3 Quote Link to comment Share on other sites More sharing options...

Fixed! @Marty Backe was right, it's NOT a variable speed fan. I just turns on or off at full speed. My problem was that I had a defective fan. Jason at eWheels sent me a new control board and fan. Straight out of the wrapping, the new fan had a crack in the top housing. It looks like something heavy was placed on it and it bent inwards and cracked. At that point, I had a defective fan and a broken fan. I figured I was stuck. But then I noticed there were little tabs on the housing that were holding it together. By lifting up the tabs with a thumbnail, I was able to separate and pull the broken piece off. Then I got the top half off the defective fan, and snapped it onto the new fan. Installed the new cobbled-together fan, put everything back together and took it for a test ride. I was riding it hard and fast (as usual!) and wasn't able to get the temperature any higher than 54 degrees C. So I'm calling it fixed! This further reinforces what I mentioned before--the quality control on these fans is not great. So far we've seen a dead fan, a defective fan, and a broken fan ... and that's just between Marty and myself. Thanks @Jason McNeil for the speedy replacement parts. The good news is that the wheel works fine now! Two different people on my ride commented that the lights were cool. It's easy to get it up to 50kph, and stable as well. It's a surprisingly comfortable ride, plenty of torque, plenty of speed, nimble ... it's a great wheel! 11 Quote Link to comment Share on other sites More sharing options...

Meh, they're a dime-a-dozen, just stock up: Dynatron DB126015BH DC12V 0.43A Blower Fan (model used on the Nik+) or Dynatron DB126015BU DC12V 0.62A Blower Fan .... just might need to borrow the old 2-pin(?) (can't remember if 2 or 3) and re-crimp or solder. Also, FYI for reference, my Nik+ fan as well is very audible in an indoor setting without bending down to hear. 7 Quote Link to comment Share on other sites More sharing options...

So what do you do with the third (white) wire? Is it there for controlling the speed or something? The plug on the control board is only two pins.

Just as EUC tires are really repurposed eScooter tires, EUC fans are just repurposed computer CPU/case/heatsink fans, etc., except dumber, since they don't utilize the frequency controlling 3rd tachometric wire (at least I've never seen this yet in any EUC mfr), hence only on/off, no variable speed. (makes sense I think, considering the debate over how precise Gotway temperature readings are, whether they are reading off the MOSFETs or the heatsink, etc.) So long as you are properly identifying all the pins, you can do whatever you want with that 3rd tachometric wire I guess, like clip it off if EUC is the only use purpose, etc. 3-to-2 pin CPU fan adapters will receive, then never pass on the 3rd wire, so the connector termination will end in the first 2 wires and physically fit the board's 2-pin slot.

Awesome! Thanks! That's really helpful. I actually did order an extra fan--just in case--and when it showed up, it had three wires. So I guess that means I have a backup fan if I need it. I peeled back the Dynatron sticker on the defective fan, and it has the same three contacts on the circuit board, but the one where the white wire went was empty. So I was guessing, I could just cut the white wire. But using that 3-2 pin CPU adapter is an easy solution! 2 Quote Link to comment Share on other sites More sharing options...

Very good news. I know of multiple Nikola owners who are dealing with overheating. Really strange that Gotway screwed this up. Every wheel on the planet overheats at 79-degrees. So then Gotway releases a new wheel that is totally enclosed (unlike previous wheels that exposed the heatheat to the outside) and lowers the overheat temperature by 15-degrees Celsius. Gotway was the king of cool running wheels but they blew it with the Nikola.

I remember reading about it somewhere. So it would read much lower temperature and make the owner think that it's a cool-running wheel. It might be that the engineers try to take into account the temperature difference between t-sensor and MOSFETs, when setting the overheat limit. Perhaps, that explains the low 65C limit on Nicola? At any rate, we don't know what we are actually comparing when we compare temperatures of different models. 2 Quote Link to comment Share on other sites More sharing options...

Are there any versions of the Monster that expose the heatsink to outside air? Also, seems like it would be an easy mod to cut a hole in the plastic shell under the control board. Then you'd have to seal up the interface with something (silicone, grommet, weather stripping) That would be true for both the Monster V2/V3 and the Nikola+ that have the control board side mounted.

Actually, I believe all versions of the Monster expose the back of the heatsink to the outside air. At least, mine does, and based on people's pictures of the insides of their Monster shells dating back through 2017, the cutouts have been part of the design from the beginning.
