Overheating Issue in MacBook Pro Fixed Drilling 60 Holes in Casing to Increase Airflow
An iFixit programmer has published an interesting story that details how he fixed his overheating MacBook Pro by drilling holes in the laptop’s body to increase the airflow.
The 60 holes were drilled in the bottom case, underneath the two fans (as seen in the image above). The holes helped decrease the internal temperature of the MacBook Pro from an average of 90 degrees Celsius to an average of 40 degrees Celsius.
“That is, we pulled out a drill. With a 1/16” bit, we drilled holes in the bottom case, under the fans (we figured out where the blades of the fan were exposed based on the dust pattern stuck to the inside of the bottom case). The speed holes worked: The boot chime rang. The screen glowed. The fans blew.”
The idea to drill holes only came after trying a number of methods of fixing the dead MacBook, including baking the logic board in an oven. While baking the logic board provided some temporary relief, the fix didn’t last for a long period of time.
“Instead, I cracked open the back of my laptop, disconnected all eleven connectors and three heat sinks from the logic board, and turned the oven up to 340º F. I put my $900 part on a cookie sheet and baked it for seven nerveracking minutes.
After it cooled, I reapplied thermal paste, put it all back together, and cheered when it booted. It ran great for the next eight months. Temperatures averaged in the 60s and 70s C—although recently, they began creeping up again.”
The programmer’s computer has been running without any overheating issues for the past 15 days, however, it is still too early to tell if this fix will last in the long term.
