I disagree
If the issue is present when the valve open, how much time do you think it will buy you by having it open slightly sooner?
I agree with MKAG, very little time, and when moving slowly, less air will be moving past the rad. The issue must be coming from somewhere else, clogged radiator, fan not doing it's job or coolant circulation(again, clogged rad.)
