We use heatsink compound of low thermal resistance to 'fill in' those little valleys and imperfections, so we don't have air keeping our heat transfer at bay. See, air is a great insulator air does not allow heat to transfer effectively. So what the heck does that have to do with all the heatsink goop I see spread around like peanut butter on a sammich? (mmm sammich - sorry, I'm hungry) Glad you asked!ĭirect metal to metal is the best heat transfer mechanism, as we've already stated, but we have those surface imperfections that we can't even see to deal with. Plenty of reading, and you can start doing some thinking on your own - Surface Finish If you'd like to read more on surface finishes, check out Wikipedia. I may have gotten the RA down to the 25 range, but it certainly helped. Now, my lapping was not the best job in the world. I've seen better heatsink bases in a DELL for crying out loud. That's freaking pathetic in a system that you pay the kind of money you do for a quality Macbook Pro.

While I don't have a profilometer available, I'd estimate the RA of the heatsink copper pads in the neighborhood of 40-60 RA. When I pulled the heatsink out of my Macbook Pro, I was astounded. I'd say that Swiftech heatsink has an RA of 3-5 microinches.

When turned on, a gray screen with horizontal "squiggly" lines appears, denoting a possible hardware failure.ĪppleInsider has reached out to Apple for comment and will update when a response is received.Do you see how reflective the surface is? That means there are very few valleys. After repeated attempts to resolve the issue in single user mode and multiple clean installations, the machine is now unresponsive.

Forcing the machine to use Intel integrated graphics also seemed to help the problem until the system went down after about one day of normal use.Ī clean install was performed, which again revived the MacBook, but this too was short-lived. Rebooting to single user mode and performing a fsck to check and repair possibly corrupted files fixed the issue temporarily. Upon restarting the machine, a blue screen was displayed and the MacBook's fans spooled up to near maximum RPM levels. In their case, the screen went black during heavy Photoshop editing. While some owners were able to take their machine in to Apple for a logic board swap, the operation is quite pricey without an extended AppleCare warranty.Īnecdotally, one AppleInsider staff member suffered from an identical issue as described in the Support Communities thread. Others, however, did not see success with the stopgap and were forced to replace their MacBook's logic board. Some have found a solution in inhibiting automatic graphics switching to the more powerful AMD card through specialized software. The cause of the reported glitches is unknown at this time, though some users have speculated that heat is to blame for aggressive degradation of the discrete GPU. In severe cases, a clean install of OS X is recommended.Īs noted by forum posts, these methods - and more - were attempted, but did not resolve the issue.

For this type of issue, Apple suggests that restarting an affected Mac in Safe Mode, or resetting NVRAM/PRAM will solve the problem. A reboot temporarily solved the issue for a few forum members, but the problems returned after a short time.įollowing the onset of graphical glitches, many users see their machine reboot to a blue or gray screen. Displayed graphics become striated in some cases, while other uses have seen their screens go blank unexpectedly. Since the start of December, 53 pages of posts have been added to the growing discussion.Ī majority of cases first see signs of the problem during graphics-intensive operations, like viewing high-definition videos or running heavy compute tasks. With 206,237 views and 2,348 replies, the forum thread dates back to February 2013 with a steady stream of posts all citing issues with the discrete graphics card. And the problem appears to be getting worse. | Source: Apple Support Communities forum member "abelliveau"Īccording to a 157-page thread on the Apple Support Communities forum, an increasing number of owners of early- to late-2011 MacBook Pros with discrete graphics cards are seeing what is being reported as hardware-related system crashes.
