COOL feature

Hello,
I am interested in the COOL function which i have just found.
I do not have a connected fan but would like the machine to slow down when then layer is less then x secs (ie. the bottom part of the screen).
If I turn the COOL option on will the 'slow down' bit work even thought I do not have a Fan (for the top bit of the screen).
Thanks,
Roger

yes

To expand:

Yes. Part of the cooling feature in slic3r is a setting for "minimum print speed." When slic3r detects that a layer will take less than the amount of seconds you put in the section "Slow down if layer print speed is below" (say, 20), then slic3r will slow down the print so that the layer takes at least 20 seconds, down to a minimum of whatever you put in "minimum print speed."

thanks all - will give it another go
