how to kill your MB temps without apple noticeing.

[johntucker09]

i actually think it was cooler than it was registering, but it would not drop below zero...

what is your temp on the macbook?

one is taking it off the top, not using a needle to take it out of every nock and cranny,

That's not the issue here, and I really hope your analogy is a joke. When you install a heatsink or heatpipe over a small blob of thermal grease, the grease is forced to spread out to fill the exact inconsistencies between the die and heatsink material. If you reinstall a heatsink over 'pre-flattened' thermal grease, you're gambling that the existing layer is thick enough to make 100% contact across the entire surface of the heatsink. What if, due to some extra pressure placed on the heatsink during normal removal, half of the processor is not covered with a sufficient enough residual layer to make decent contact with the heatsink above it? I've even heard from someone on this board that when they reapplied thermal grease to their MacBooks, they pre-spread the grease with a razor into a thick layer to prevent making a mess, but the heatsink still didn't make complete contact, due to the heatsinks not being perfectly flat in relation to each other on the heatpipe.

So, originally I replaced apples paste with my own generic white goop

hehehehehehe Sry, I'm just feelin very immature right now

My MacBook Pro runs pretty damn hot at max load.

Ditto, and mine's been sent back for overheat problems twice

"well... it is within spec..."

i'm not gambling because it's easy to check, you put the paste on how you think it should go then you put the plate back on screw it in and then remove it again too see where the contact is, then apply as you see fit. this is thermal paste not rocket science, you just scoop off the paste around the die and flatten down the paste that's on the die, it's not all that hard and it has brilliant results.

I never said thermal grease was rocket science, I merely stated that expecting an existing layer of thermal paste to make good contact across a heatsink that probably doesn't sit flat on the die anyway due to it's construction is just asking for problems down the road. Expecting that twice in a row would be even worse. I don't blame that on you, though, as Apple seems to still be figuring the whole thermal grease thing out themselves...

you just have to check so you have the thinnest possible layer that gives complete contact, and thats far less than what apple uses.
