The nice thing about mesh is that it breathes. Long gaming sessions during the summer (even with air conditioning) are brutal in a chair that does not breathe. I go a step further and have a fan direct air towards the back of my chair - like a cooled seat in a car.
No matter how good your chair is, you should be getting up and walking around periodically (or using the "stand" feature of your desk, if you have it). Sitting in the same spot for hours on end is really bad for you.
That said, I've thought about getting a fan to circulate air around my seat and legs at work. The room I'm in has a bunch of people who like to keep the room way too warm. I already have one of these
on my desk and it helps a lot, but only with my upper body.
