Thermal compound on macbook pro's

So I finally got the guts to break down my macbook pro lastnight. I had heard rumors that some of the earlier batches of these (like mine) had gotten bad thermal compound jobs. Well after about an hour of breaking it down and 4-5 near heart attacks (Nothing broken) I turn it over and to my surprise the thermal compound is all over the place. Over a millimeter thick of cured compound on each one so bad it had gotten off the core of the chip. This was a HORRIBLE job done I had bought an oversized tube of Arctic Silver 5 for this purpose on my last desktop build.

I'd advise anyone with a good amount of computer hardware knowledge with an early make Macbook Pro to do the same.

After another hour of putting it back together, I noticed the temps dropped from a rather high idle 48C to a amazingly low 37-39C Idle Of course since I run my macbook pro overnight that temp has risen a bit but still much lower than it used to be.

i havent done mine yet, but i see no real reason.. it never runs that hot, maybe 50s.

load maybe 75c

ive had everything but the logic board taken out.

48c is not a high idle, its normal, but more power to ya

kgeier82,

I thought you ripped into your old MB and put Arctic Silver 5 in it?

I figure it can't hurt any.

Good post kaltek! Lowering the heat down 10C was well worth it.

yep, that was a MB, a little different setup than the pro's. the pro has two fans in it, and to me that keeps it cool enough.

the mb always ran hotter than the pro anyways, just so small in there


like to see some before and after temps from you though.

Thanks guys

sorry no before pics I kinda did it on a whim (was late and i was bored and it ended up taking me till 4am to get it back together)

Temps have definitely lowered. Its kinda hard to show because I run my macbook pro 24/7 But the normal temp is much lower than it used to be after leaving it on overnight.

ok, well, at least what are all the after temps?

if you were running 48-50 idle before (like me), im sure your max temp was about 80-83

My load temps before I did this was 75C i wouldn't let it go any higher as thats close to the thermal threshold. (this was in windows gaming at 1920x1200 which had something to do with it) in OSX it never pushed 55C

now I get a steady 45C and 50C load when used for over 24hrs. If i shut it off it will idle at 37C (body temperature) for about two hours and slowly begin to go up but always levels off at 45C when left on.

just so u know, i believe max temp for these chips is 100c.

it could even be 125c, i lost my link

30c difference seems a little impossible im not gonna lie. the results on my mb were no where near that, more like 10c max.

but good for you if your getting that!

75C was on windows with heavy gaming. I haven't tested it on windows with the new compound applied. I would assume its higher in windows seeing as it doesn't use osx power management techniques.
