Here is the original horror story:ĭon't forget to update EFI before using either method, or your new CPUs won't be recognized and your Mac won't boot. If you don't de-lid, you will need to use great care when fitting and tightening down the CPU heatsinks and add extra thermal padding to thicken the existing thermal pads. He also offers the necessary 3mm hex wrench, thermal paste, and firmware update in order to install these CPU's for one-stop shopping. $130 for a pair seems like a reasonable deal to me. He has a sure-fire approach and has done a whole bunch of de-lidding jobs. You can also pay this guy at Ebay to do it for you: Michael Canavan, who successfully de-lidded his Xeons, talks about it in detail in the Xeon thread. I haven't done either Emu, but there are proponents of both approaches with success stories. To de-lid or not to de-lid, that is the question. If any of you have done this would love to hear how it worked out for you.
