"Customer" is not the real term ;i am simply happy to share my old knowledges with everyone . I guess all the 2 speed PCB's have the same feature : Their Hi speed triggers at too high temperature (around 115 deg) I'll confirm when rovertone will send it Mike |

2016 new
Happy new year to all of you .
I have tested the genuine Fan PCB Tony sent me and found nothing wrong . -It’s a genuine 2 speed with no faulty component The results: -Same test conditions as the 3 speed , in percent of duty cycle: (I don’t know the exact correlation table between temp and duty cycle) 3speed genuine Low 15% Me 40% High 70% Tony' 2speed genuine Low 15% High 75 % AFTER MODIFICATION for his peace of mind (one resistor value changed) Low 15% High 65% In these conditions Tony has measured: 1st Speed: On 97C Off 95C 2nd Speed On 110C Off 106C So no Wonder that 75% could be 115 C or more ? I have not yet received those from Steve ;I’ll confirm soon .(i guess) If they have the same behaviour ... Mike Last edited by FrenchMike; 11th January 2016 at 15:52.. |
