That´s depending on the hotend you´re using and what material you´re printing with - PLA or ABS?

In most cases cheaper hotends needs a cooling anyway. The reason is that the insulator and/or the sleeve can´t withstand temperatures above 200 or 210 degrees C. On top of that there is no thermic insulation between the parts of the hotend and they are usually to short to do so.

There are some hotends out there which needs not be cooled at all, I know at least one which is J-head compatible. Costs about 70,- EUR + shipping, but believe me, that solved a lot of my issues with wraped prints.

Again, it would be good to seee a photo of your printer or at least an link to your extruder (incl. the hotend).
