I was having huge heat creep problems. My prints would work if I printed very fast and did zero retractions, but this lead to poor quality. I was printing in my garage and temps get up to 100f. The small fan on the cool end was not enough. I then put on a blower style fan and that improved but I still got issues. I could only print when a storm rolled thru and the temp dropped to 75f.
So I built a watercooled hot end and no I am printing day and night!!! I am so happy this solved the issue. I was getting SO frustrated.
Here is a video of the water cooled cold end

If you are prining in an enclosure, and temps are getting in the 100f you may have the same issue.
I hope this helps people.
Thanks
