Print Profile(1)

Description
Top housing for a GMKtec K12 120mm
Warning: Soldering experience required!
Noctua fan only fits into the casing without vibration dampeners on the corners!
Please note:
The models are designed to minimize overhangs
For the best print result, definitely print in this orientation
Only the case lid requires a support structure

Adapter 4 PIN JST 1.25mm to PWM 4 PIN extension, so that every fan can be connected without needing to solder again
(Pinout in the documentation)
BIOS: CPU fan curve to automatic, SYS FAN to 40 percent
Set to PERFORMANCE in the main menu

Before:
Cinebench R23 95 degrees Celsius including thermal throttling
RAM Temp 70 degrees
