Is there a tell tale sign of a bad t-stat. code? would I overheat or do the fans prevent that? I put my 180 in about 3 weeks ago and at first everything looked ok my temps were between 1 bars pass the quarter mark and 1 Bar past the half mark. Big difference between how It ran stock tstat. but......As of a few days ago it seems to not get down as low as before and goes almost 2 bars past the half mark and stays there for longer even after cruising consistently no stop signs. Now I understand its been fuckin hot out here lately but even late last night (79*)and this morning (75*) it didnt seem to get cool enough as it did when it was installed. The temps then were a consistent mid 80's this first week i had it. SHOULD I be concerned or am I being paranoid?
