The age old 98.6 °F is getting debunked by more modern study that put an adult's normal body temp roughly a degree lower and with some variation. Feeling a fever has been shown to be a degree or so lower, and variable, than the common 100.4°F cited in a lot of medical literature as well. Given what I know about my own temperature, I would expect a Pringles fever would fall into the 98.0-98.5°F range. I personally feel that something is a little off at that point, but I'm not feeling ill. I expect Pringles to give me high blood pressure, not a harmful fever.
