You can add some fuel to cool it some if you want. Add to F maps but it can possibly throw off your smooth throttle depending on the tune. Just keep your current map so you can put it back in. The fourth bar on the temp scale is 158-212F. Fan kicks on at 216F. Mine seems to kick on about 30 seconds before the fifth bar shows up. Operating temps are all close. The newer 990's have more bars on the gauge than our older ones.
