Run fan only on perimeter possible?

I have a problem, if I don't run a fan I get the corners curling up on all my layers. If I do run a fan I don't get good adhesion and my parts are weak. Is it possible to only run the fan on perimeters and not loops or infill?
If so, what software will g-code this?

Thanks!

KissSlicer let's you do that.
IME it's not very useful if you are having issues when running a fan you'll have them even if you just run it for perimeters.

Also my branch of Cura has this feature [github.com]

Polygonhell, so you think that the fan during the perimeter will cool the infill of the previous layer to the point I will still get weak parts?

If I turn a fan on part way through a print I can see the line in the print where it was turned on, this is mostly because the Hotend can't react fast enough to keep the temperature consistent when the fan turns on, I see about a 5 degree swing. Now it may be different if you have a fan duct that works better than mine and better insulation on the Hotend than I have.
I usually either print with a fan always on, or with no fan, and I set the temperature so I get decent layer adhesion.
Just what I do YMMV, you an always download the free version of KISSlicer and try it.

I'm just posting to follow the topic.

I run slic3r and have the same problem, but i have no experience using other softwares, and would love it was implemented into slic3r.

Is there a way that i could tell slic3r to turn on my fan for a certain amount of time after each layer change using the custom g-code tab?
