Cooling issues at 80f

I was grinding my way up an abandoned steep road grade in first gear, it was 80f, and I could feel the heat coming up through the seat. We stopped, the fan was running and another 15 seconds and stopped. If you listened carefully it sounded like the coolant was boiling. Not boiling over just boiling in the radiators. I had never hard that and am concerned. It's just starting to get hot around here.
I didn't think the xc-w had this issue.
The bike is stock except for the acerbis tank and the 14|52 gearing.
The bike is acting like its running a little lean as well.
Is there a better coolant? Seems like the least modifying and least expensive way to go?
Thanks
