That Pentium is a 53W part, whereas the i7's a 95W part, so it'll take far less to cool the Pentium. As well as this, 80° isn't that hot for a modern CPU, as long as it's a peak temperature. The system would shut itself down before any permanent damage occurred, so major failure's not a possibility, and if a part gets that hot with Intel's cooler, then it's clearly within Intel's specification for the part.
