MacBook Pro :: Having Heat Sink - Boot Up Temperature From 20 - 130 Degree
Jul 13, 2009
I Got a 13 inch MBP and gave my 13 inch aluminum MB to my dad. However i noticed something with the new MBP i got. A)After installing istat pro on both machines only the older MB shows as having Heatsink A and B, the new MBP shows as only having Heat sink B, how come? The aluminum MB on boot up has all the temps (CPU, Heat sinks, HD and so on) going around 20-30 degrees FH, yet the MBP is coming up with 90-130 degrees FH. After 1 hour use the MB has all reading between 28-48 yet the MBP has all readings between 90-140 degrees FH. Both kept in the same room, doing the exact same thing (running safari, same site). I just dont want the nightmare i had with the MBA where i had to return it 3 times because it would over heat and crawl when doing anything slightly intensive. Mine are:
HD MACINSTOSH 83
CPU 131
ENCLOSURE BASE 90
ENCLOSURE BASE 2 90
ENCLOSURE BASE 3 89
ENCLOSURE BASE 4 91
HEATSINK B 113
NORTHBRIDGE 108

I got my macbook pro core i7 yesterday. I found that the cpu temperature is 20C more than the cpu heatsink. is it a problem of my mbp? just curious to ask because it is just 2~6 degree Celsius varying in my mac mini.

What is your heat sink temp when the cpu is running hot, like 90+ degree C?
I recently performed the excess thermal compound removal procedure. Now I am worried that my cpu and heat sink are not in 100% contact, due to the very small amount of paste applied.
My heat sink sits at around 50C under normal load (cpu temp ~ 60). But at high load, cpu up at 90+ C, my heat sink is still at around 50-60C. Is this normal?

So, at my college, some departments own Mac Pros; one of them decided that they would like to fit the Mac Pro into a smaller space, so they cut ALL the handles off, which of course removed the heat sink, so the computer overheats. Long story short, the computer ended up in our tech trash, and I took it, DUH it's so beautiful (even without the handles). How can I make this computer usable? Would a water cooling system do it?

I just bought a G5 case to house my Quad Core 2.4GHz hackintosh, and would like to overclock it. The only problem is, I don't want to have heat issues, of course.What would the best heat sink be to use that would still fit inside the G5 case?Could I maufacture/build/hack together my own heat sink?Should I just put it into a refrigerated case

At my university there was a flood during christmas break while I was away, and my office had about 8 inches of water in it. When I got back, I saw the damages and was quite sad to see my mac pro filled up with dirt and debris.
So I cleaned it out and tried to boot it up and amazingly it works almost perfectly...in fact I am typing this on that mac pro. The only damage is that the fans now run at 2500rpms all the time.
So Here are my temps from iStat. It seems like maybe the sensor for CPU B and the north bridge are messed up. Anyone have any experience with fixing/replacing those parts? I am wondering if my diagnosis is correct and what is the best way to fix this machine.

My CPU heat sink fans always run above 2000 rpm. Is that avoidable?
Can I do something about that to drop the speed and get rid of the noise?

So mines at 142 degrees... that seems high to me but i am not really sure... i guess it is a heatsink it should be trapping heat

so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]

i've had the macbook for about a month now and I noticed that theres times when I boot up the macbook my temperature hovers around 70C (didn't turn on from sleep mode) i'm using smcfancontrol to see the temperature and I could feel it too, then when I restart it the temp drops and just hovers around 40C does anyone know why?

I'm wondering if anyone could tell me what the normal temperatures are when booting Windows on a Macbook Pro.I'm getting around 60-75 GPU temperature and about 48-60 for CPU when I'm doing normal things like I do in Snow Leopard.Is that okay? Is it also okay to have such temperatures for like 5 hours straight or so?I'm getting around the same temperatures when I'm using Snow Leopard, but the laptop doesn't feels as hot as it feels when I'm using Windows, and that is bugging me much.

I noticed that iStat and Temperature Monitor report different temperatures for the same readings on my G5 Powermac Dual Processor System. For example as I am writing this Temperature Monitor is saying My CPU A is 46.8C and CPU B is 46.7C. In iStat it says CPU A is 55C and CPU B is 54C. Which is right!?

I apologists straight away if this have been covered recently, but i need to ask.I have MacBook with Intel Core Due Processor, 2 GB ram.What is the average temperature CPU temperature for standard usage ( I know that standard usage is very arbitrary, and by this I assume safari, iTunes and let say Pages to be the only major apps running ).I use iStat pro widget and according to it my CPU temperature is 55*C. Is this too high? Lately the fan has been turning on more recently almost without any apps running so I think that there might be some hardware problem. I ran HardwareTest it found nothing.
The macbook is 2 yrs old. Do i need to get it cleaned or is there something else I should be worrying about?

I have a late 2008 uMBP 15 inch and in safari, regardless of using the integrated graphics card or the higher end card, when I press apple t for a new tab the computer hangs for at least 10 seconds then once it finally loads the top sites page it appears all scrambles for a second, then it works normally.
My second problem is that my hinge is very loose. I can't hold the laptop at 45 degree angle without the screen falling down and closing. Will apple fix this?

I am trying to make a chart and I am trying to make the top row of colums with the information postioned on a 45 degree. How do adjust the setting in numbers or pages to accomplish this.
Info:iMac, Mac OS X (10.7.2)

It either interprets "diagonal" scrolling as horizontal or vertical, or left and right. There is no horizontal and vertical at the same time. I don't recall my previous MM being able to scroll diagonally, either. I'm not sure what Apple means by "360 degree scolling."

As the header says, the fan in my Mac Pro is now operating at a constant 2700 rpms and, per iStat, believes that Core 4 is at 260 degrees. This is from COLD startup as in overnight. All other cores are operating in the low to mid 70s. So, obviously it's impossible for core 4 to be 260 degrees on startup and highly unlikely it would be that hot, ever. I've done the SMC RST thing both ways (button pushing and unplugging).

i think my macbook is running rather hot lately as I have the fan set at 6200(max) and it seems to idle at 50C and I had skype running with a few people and it was reaching 80C! It never used to get that high before! It is a Dec31st 06 (lol 1 day from 07) model and I do have the ability to open these models and apply the thermal paste again as I have done plenty times before and also fit Mac Pro serviceable options such as BT and AP
I know how to open it and clean it but theres no dust in it to make it that hot I might have to try max load and see if it overheats

Bought a macbook air recently and enjoy using it to listen to music and work while laying in the sunshine, only i have noticed it gets increadibly hot and when watching a movie cant quite play it smoothly as it seems to be affected by the heat. The aluminium obviously heats up easilyShould I avoid using it in the sunlight? Are there any addons i can get to keep it cool? Anyone know anything?Temperatures here in southern Spain now in the summer tend to be around 30?c (air temperature) but more in direct sunlight.

I am designing a stand that will allow me to slide my Mac underneath my Dell U2410 basically. It will be made of wood, and the mac portion will be raised ~1" from the desk. The front and back will be open, and I'm also going to make slots for the optical drive as well as a hole in the left side for I/O. However I also want to make sure it doesn't get too hot. So basically I'm wondering if there is a central place where the heat essentially "exits?" I was thinking of putting a few holes into the board so that the heat could leave the stand that way...but any other ideas?

I left my mba open, with the screen saver on, not running any programs for about 2 hours. Came back and the fan is at 6200rpm and the CPU temp is 180 degrees. It hasnt been doing anything at all. I dont understand why it is working so hard. What should I do?

Once anyone gets to test the new MBA out (next month?), if you can please post the results on heat issues. Eg the initial MBA in many cases was only usable at 50% CPU/GPU (for more than a few minutes) due to heat issues. Does the new one fix it? If so, it is effectively more than double the speed.. more like 3-4x faster if that makes sense. If GPU is much faster AND heat issues are fixed, this could be a huge performance boost..

I am 99% going for the MBA. Now the question is HDD or SSD?!I have read all comments about speed difference but I would like to know the difference in heat between the two. Really dislikes heat in a laptop and hence if there is a difference between the two

I went in to the Apple Store yesterday to buy a MacBook pro 15". I currently have a 2009 13" MacBook Pro. I decided to go top of the line with the i7 even though the Apple Sale Person said I didn't need the speed. I wanted to not look back later and say I should have gotten the best. What I noticed last night was I had it on my lap on battery power doing my normal surfing. On flash sites it got a bit uncomfortable on my lap. About 70 degrees C. I have never noticed it before on my 13". Should I take it back for an i5 and would that make any difference or is all of this just normal for this type of computer?

I use my MBP (Unibody, 2.8Ghz, 4GB RAM, running 10.6) in clamshell mode connected to an Apple Cinema Display ... Been doing that for a year and a half now and never had any problems.Now, since a week or so, my MBP keeps shutting down randomly, probably due to heat issues.So I installed SMCFanControl and run it at max RPM. Still no help.My system reaches over 90?C before it shuts down.Now I disconnected my MBP from everything (ACD, speakers, external HD, iPhone dock, Ethernet cable) and when running on its own off battery power, the temperature has already dropped down to 60?C and it stopped shutting down.
