I've forgot the fans once or twice, and had that happen. On the plus side, our gauges read WAY over what they are. My gauge normally reads 210 and my digitial never goes above 198ish. I've been thinking about a colder tstat...but everytime I go to buy one, I remember that during winter, it takes about 30 minutes on highway before truck hits 180 as is with stock tstat lol.
