Mr Hutto,
I can say for a particular situation of mine that our 13th green in 2010 we received a record amount of rainfall, high temperatures and high humidity that mowing greens at .180" and .200" twice a week did very little. This green has a long history of losing significant grass both in the winter months and summer stress periods. Raising the height of cut, lessening the amount of rolling and cutting has not prevented turf loss. In fact this green has always been mowed and rolled differently than the rest despite weather. However some other greens that I have tried raising the height of cut has worked very well. It just depends.
The 13th green I mentioned where we cut at .180" has since had several hundred trees and underbrush removed. The green is much better but not like the others because we also have drainage issues and the green is 2,800 square feet and sits in a small bowl that makes it impossible sometimes for westerly winds to hit its surface. Also the green is directly against our eastern property line which means the neighbors trees cast a shadow over the surface in the first half of the morning. If greens renovation or intensive drainage is not installed then adding a fan is a possibly if we want the putting surface here to be consistent with the others on the course.
My recommendation is to renovate the green for several reasons: 1) its very small 2) it has both surface and subsurface drainage issues that are not easy to remedy without significant work 3) we cannot do much about the trees not on our property 4) Because of the geography of the situation little more can be done to improve air movement but to use a fan.. We have contacted Mr. Nuzzo to see what options are available to us in the department of renovating the green so that we solve our inherent drainage issues and increase the number of hole locations. At this time I would not recommend using a fan unless issues arise and all other avenues have been exhausted.
But the go ahead to renovate the green or take other measures is not in my control, its up to the members to decide. That being said even if we renovate the green I cannot say with 100% certainty that we will not have to use a fan. But in my expert opinion with a smartly done renovation we should be able to produce a putting surface that is as good as the rest. If not, the only other option besides blowing up the entire hole(which is not an option) is putting in a fan that would only be used during stressful periods and can be hidden quite nicely in this scenario.
I will not comment on other courses unique situations because I am not privy to all of the information that only the superintendent or turfgrass professional with knowledge of the site and circumstances can provide. But I hope my scenario that I have encountered will help…
