Would a chi straighter still burn my hair?

Right no i have a Conair one and it heats up to 30 i guess. I get a burned hair smell from it. Would a chi do that? I'm thinking of getting this one a href="http://www.walmart.com/ip/Farouk-Ceramic-Hairstyling-Iron/14574741#ShortReviewTitleBar" rel="nofollow"http://www.walmart.com/ip/Farouk-Ceramic…/a . By the way i use Tresemme heat protection on my hair. That still doesn't work.
