hi everyone, I have a couple questions that I hope you all can help me answer.. I have 2 original neotats and my 3.5 is getting really warm after about 15 minutes or so at around 10.5 volts using t-techs. my 2.5 doesn't seem to get very warm at all. they have about 30 - 40 hrs on them so fairly new. my 3.5 seemed to get a little louder as well so I did take it apart and lube it up. I was just wondering if this is normal or if I may have to have it repaired. Thanks in advance for all your help!!! forgot to add that running without being loaded it gets warm as well just take about 20+ mins or so
