Hello! Glad to have found this forum! I have several liquid damaged 2010 Macbook pro's that all have the same issue. When booted the fan almost immediately spins up to 100% and the system runs very slowly. I have followed all voltage rails and find nothing out of the ordinary. I have also tried SMC reset, PRAM reset, tried swapping batteries, HDD cables, RAM etc and nothing seems to make any difference. Any suggestions as to what to try next? Thanks!
