You're correct, the drive's on the right side. But my left side is scorching hot. It's the black blob above the battery and to the left of the hard drive that heats up.
I've now re-formatted the drive and did a fresh install of Snow Leopard; will see if this helps. At the moment, no help at all, but the Spotlight is still indexing, so I have my hopes
When I open my Activity Monitor, I have SystemUIServer at 1.6% of CPU, Activity Monitor itself (1.6%), and Safari (0.4%). The Spotlight isn't getting shown. My fan is blazing full speed, and the whole left side is a frying pan.
My battery drains real fast now, supporting that frantic fan activity.
I'll consider the thermal paste change, but at this point I'm pondering dumping the MBA altogether. The old stock SSD is dead; the replacement at Apple was too expensive, the Runcore SSD is frying my motherboard. This MBA was my main writing machine; now I can't touch it.
As for the sleep problems, no - none at all. The firmware at my Runcore is the latest one, 1916 or whatever the heck it should be.
what happens when you swap back in your old drive ?
