Test size. The larger the element, the more important it is. Test the size of the countdown relative to other elements on the page.
Test the specific wording. Try framing the deadline in different language or numerical value. For example, “2 days” against “48 hours”.
All of these ideas are easy to implement using split testing tools like Optimizely.
