did you attach a heat sink to the mosfet ? My kit came with a heat sink... The reaon I ask is I am about to powerup my Sanguinololu 1.3b & am a little worried after reading the reports of these overheating when attached to the heat bed... but having said this I notice the latest update..
Version 1.3b - Updated April 4, 2012
MOSFET changed to SMT versions capable of 76A drain current!
