Generally the heller exl range has issues in cross profile, some machines more than others. I have see as bad as 15 deg c and as low as 5 deg c ranging from entire length to a few zones. They never match the specification in reality. The markiii is

Most of this you have probably covered, but these are what have caused heating issues for us in our 1707 EXL. First, you would probably notice, but check that all blowers are turning by looking at there cooling fans in the top and bottom, Our 170
