On another thread, now lost in the mists of time and the bowels of Apple’s forum servers, someone asked about losing (or possibly stripping) one of the screws used to close the memory compartment. A reply suggested just going into an Apple store and asking one of the G folks (being careful to avoid their G spot) whether they'd give you some … ahem … screws
Oy…
I wouldn't ask them for the Torx-head screws, though. That would tip them off to the fact that you disassembled your Mac, and as far as I'm concerned, they still owe you assistance and in-store support even if they will no longer provide in-warranty hardware repairs.
The other possibility is to find a local tech-mart for this sort of miscellany. It's good to have access to random parts, tools, supplies and whatnot. (We have Fry’s around here and they're big and handy and have lots and lots and lots of stuff. Possibly even screws.)
have anyone noticed that after applying the AS5, the fans are so much louder now? i know its because they are workign hard, but man, when i first boot into windows, they sound like jet engines....
Interesting. I trust you were very careful about replacing the existing heat-sink compound with the new fancy stuff?
Have you noticed whether the air coming out the back is warmer? Or if the case on the bottom is cooler (or warmer)? We really need software access to the temperature monitoring sensors in the new Macintoshes.
I'm fascinated that the MacBooks might be manufactured with such poor thermal junction between the chips and their mounts or heat sinks / pipes that re-mounting them (with or without the extra-fancy heat-sink compound) could have such a profound affect.
Maybe we should try to get Apple to sell kits again. We could put systems together using all our own favorite tricks. It could even spawn a whole after-market for custom built / mass-market Macintosh hardware. Don't need your ExpressCard/34 slot—I'll put a wireless data link (the cellular kind) in that area instead. Don't need an optical drive? I can double your battery capacity. And so on…
By the way, except maybe for the boron nitride, that Artic Silver stuff looks like it would make fine (but expensive) sunblock…
Thanks for the advice. Fortunately, both of the messed-up screw and lost one are not T6 screws. Or I will not give them my service number or something when I ask them a T6 screw.
I also felt that fan or fans are working more. I don't know anything about thermal compound, but the system might react differently a few days later if the compound will get stable (I don't even know if it will get stable or dry).
well the powerbook definitely runs cooler, the air coming out of the duct is also hotter, so i know the coolant system is working... its just that the fans are loud, im just wondering if anyone who modded have fans as loud as mine
Are the temperature sensors located near the chips you worked on? Could you have inadvertantly altered how well they sense the temperature? Perhaps that’s responsible for some (all?) of the improved thermal regulation?
I am sorry to hear about the lost screws (Oy is right). If we could confirm that the MBP screws are the same as the PB screws, The Ifix it site sells a set. You might want to e-mail them, since they initially disassembled the MBP and ask them.
For those trying this fix, (and think long and hard on it as I do not want your MBP on my conscience) I cannot stress enough how important it is to fasten or seal away the screws as you work. You also really need to make sure you are grounded properly.
Perhaps the safest way to fix your MBP would be to point Apple to this thread and have them look at your MBP's Logic Board/heat pipe assembly, which raises the question--has anyone who has had a logic board replaced experienced the heat problem afterwards? I would like to think that the apple repair techs are doing a better job then the initial assemblers.
One of the sensors is attached to the right side of the heatpipe (that small green thing) and the other is a little more to the right and is attached to the bottom of the casing.
I could imagine that the sensor on the heatpipe (which would probably be called CPU temperature if we ever get access to the sensors) is reading much higher temperatures when more heat is conducted through the pipe, causing the fans to switch on.
My fans work but they are not jet engine loud. The left fan is louder than the right but it sounds like an ambient swooshing or really really low whine. Here is what I would recommend, run the full diagnostic and see if any errors pop up. My recollection is that the diagnostic test also test the fans.
Also, AS5's efficiency reportedly increases over several use cycle, something I have noticed with my pc's, but not systematically tested.
Frankly, I used AS5 cause I had some on hand, but any quality thermal paste would do. It is the mode of application that I suspect really matters.
Due to the unique shape and sizes of the particles in Arctic Silver's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.
Mine is 8610. I have to say with the heat fixed and the 7200 RPM drive, this thing is a dream. Could it be I have found the machine I will keep longer than a year....naw, the conroe and 64X macs will be out soon.
I can’t make out any of the features you’re describing in that picture. The only “small green thing” I see is at the front edge, to the left of the IR sensor and the cover latch.
Anyway, that’s what I was thinking, that some part of the change applied caused the heat sensor to read higher temperatures and hence the fans are being run faster. No doubt this keeps the internal temperature lower.
How’s the sound output with the fans running fast? Objectionable?
Heres something you guys should try: reboot your MBP and DO NOT disable the whine using any method and it should run cooler. I did this and right now I am encoding a video which is using up all my cpu and the bottom of the MBP isnt warm at all.
