 *Printing with normal PETG: can get weak layer adhesion at 240C nozzle temp, although the print will look completely fine. Printing normal PETG at 260C (can do 255 or even 250 if you dare) resulted in strong layer adhesion and the prints came out fine
 *Printing with rapid PETG: seems to be fine at 240C, but the profiles are set up for 245C just to ensure strong layer adhesion because the K1 is really cranked up to the max speed lol, the future!!! Printing the rapid PETG at 260C resulted in droopy overhangs and more stringing.
+== Note about noise and cooling ==
+* The fan in the print head is really noisy when running fast, making an annoying high pitch noise. At ~60% or below the pitch is bearable.
+* The official creality PETG profile has the model fan at ~90% and the side fan at 0%, however this is so noisy and annoying lol
+* Rana has changed the cooling profile so the model fan is max 60% and the side fan is running at 30% constantly. These settings are on the soldering bench computer too.
+* If you wish to change these settings, they are in the material profile:
+** Creality slicer 5.0 -> "Material" in the top right corner, click the down arrow, the nozzle and bed temp will show, click the pencil icon to the right of them.
+** The second tab is "Cools" (...lol), the speeds are changed under "Part cooling fan" (aka. print head fan, aka. model fan). The big side fan is "Auxillary part cooling fan".
