MacBook Pro :: Finding Internal Temp Difference (lid Open Versus Lid Closed)?
Sep 4, 2009
I was considering picking up this stand for my uMBP:
One thing that concerned me was having higher CPU temps with the lid closed.
I read a thread a few days ago that said there is no CPU temp change between lid closed and lid opened. And after doing some of my own testing I now believe that information is FALSE.
I use smcFanControl to control fan speed and monitor CPU temp.
Before using smcFantControl to boost my fan speed to constantly run at 3,400RPM, my CPU temp was 10-20 degrees (celsius) higher, on average.
I listened to a few U2 songs encoded with AAC and Apple Lossless. Listening through the standard ipod ear buds, I honestly could not tell the difference.
Has anyone been able to notice a discernible improvement with Lossless? If so, what type of music/speakers were you using?
How much speed difference is there? Battery I take it is almost double in real life, actually using the MBA. I get barely 3 hours with moderate use on my Rev B and I take it most people get close to 7 with similar usage?
I have a fan utility that lists 2 fans. The "Left" fan is at 6204 rpm's, temp 81.4C The "Right" fan shows 0rpm's, temp -1C. Is this merely because the sensor is capable of recording two fan speeds or do I really have one malfunctioning fan? (which would explain the high cpu temp, if it applies).
A third sensor, a widget, records the same temp, with Heatsink A 70C and Heatsink B 64C. I realize all three sensors are getting their readings from the same spot; which one do I rely on?
I've just ordered a MBP 2.4Ghz with 7200rpm 750GB drive, I will be adding either a single 8GB memory stick (total of 10GB) or a 16GB kit. I'm looking for my first SSD use as a boot drive for OSX and potentially Win 7 in BootCamp and hope I can get some counsel on model selection and configuration. I read that SSDs suffer a performance drop (sometimes significant) as the drive fills up. Also there are both 256GB and 240GB drives.Â
1) Are there models that maintain performance over time? Is there a specification that indicates how performance drops as the drive fills up?Â
2)Â Is there a performance difference (current / long-term) between 256 and 240GB drives?Â
3) Does an abundance of RAM improve performance and / or longevity? Â
4)Â How much space (if any) should be kept free for swap files in OSX / Windows?Â
5)Â With 240 / 256GB SSDs, how much usable space is available after formatting?Â
6)Â Is there a difference in performance based on file format NTFS vs. HPS+?
7)Â Do I need to be concerned about major name brands (Intel, Samsung, OCZ, Kingston, etc.) being incompatible with MBPs?Â
8)Â Are some SSDs easier to install / configure / maintain on a MBP than others?Â
9)Â Are there any issues I should be aware of regarding the installation or use of a SSD that would impact my MBP's warranty?Â
Based on performance, reliability and 5-year warranty, I've been attracted to the Intel 520. I've also read good reports on the Samsung 830. One review indicated that the 830 maintained performance over time while the 520 experienced a significantly greater drop.
Info: MacBook Pro, Mac OS X (10.7.3), 2.4Ghz, 16GB RAM, 750GB 7200rpm
I'm confused - when I look at my Storage info under the "About This Mac" item, my internal drive shows that it has "141.6 GB free out of 499.25 GB" Yet when I look at a Finder window, the drive shows 230.89 GB available. That's an almost 90 GB difference. I'm assuming (until someone tells me otherwise) that the "About This Mac" information is the 'truest' but I, frankly, don't know.

I'm looking to finally upgrade my Mac Pro to use an SSD as a boot drive, and I've been eyeing the OCZ Vertex 2 drives as a result of the beloved Sandforce controller. My question is, the only OCZ drives I've been able to find at the price point I want in my area are the Vertex 2 3.5 120 gig editions.

Is there any reason NOT to get this over the 2.5 version? I'm not planning on putting it in the optical bay as both are in use, and would just go in a regular hard drive bay. It's unfortunate that I wont one day be able to use it in my Macbook Pro should I ever upgrade however, beyond this am I suffering any penalty by going with the larger size?
I have a Mini 2.53 I'm using as a HTPC and It's great. I also have a 17" MBP 2.66 which never leaves my desk. I do mostly photo editing. Anyone know if I'm gonna see much difference if I slim down to just the Mini? I'm thinking of selling the MBP for the cash.
Also, I can run my dual Apple 23" Displays on the mini and cant on the MBP.
I downloaded a program to monitor my late 2008 unibody Macbook Pro's temperatures. Just a few minutes ago while playing music/playing an ONLINE game real briefly it warned me that my CPU temperature was too high. (167Ëš F) Is that too high of a temperature? What should the "range" be?
So when the windows 7 beat was launched, i ended up choosing to download the 32-bit version as I knew it would run, and I wasn't sure if I was compatible or not.
1. I have a 20" iMac 2.4GHz 2GB RAM etc. Is my computer capable of running 64-bit?
2. Whats the difference between 32-bit and 64-bit? Is 64-bit faster?
I was wondering what the 'normal' operating temp for the hard drive in an emac is supposed to be. According to iStat, the hdd in mine is currently running at 77 degrees C. It has only been on for about an hour and a half. I'm pretty sure no hard drive should operate at this temp.
Today I noticed that there is really lots of color difference when I look at an image on the web when i use firefox in comparison with firefox. For example the red collors are really really bright on firefox but in safari they look not bright at all. Actually safari is more accurate. How to fix color when using firefox (my main browser) are there like certain setting you guys recommend?
I have a MacBookPro5,4 2.53GHz with one fan and only the 9400M. After updating to 10.6.3 the operating temperature seems to have risen from about 43 degrees C to about 48. It has been getting warmer here in Japan so the ambient temperature is different but I still think this rise in temp. is due to the update. I have smcfancontrol installed and set to 2500rpm instead of the normal 2000, but it seems to be not enough to keep the temp. under control, as it did before the update. Any relatively hard use of the cpu and the temp goes up to 60 degrees.
I'm going to eventually buy a reburb white Macbook and I am contemplating between the 2.1GHz and the 2.4. As far as the ram and hdd are concerned, I plan on putting a bigger drive in and upping the ram to 4gb, so the only difference left is the .3Ghz.
The money saved by going with a 2.1 would just about cover the 4gb and a good 320GB HDD.
My plans for this laptop are: surfing, some work in Windows (thus the ram), itunes, iweb, iphoto... no gaming planned, I'm just not a gamer.
I understand that some of the early core 2 duo's are different than the current core 2 duo's being used in the current 13" MBP's. I understand that some are T8000 series or T9000 series (I think??).
My question really is what is the difference between the earleir C2D's used and the current ones. Some of the earlier ones seem to have more L2 cache, do the newer ones run on a lower voltage? Have a different chip? Are quicker/slower?
I haz a serial problem, but I'll spare you the plea for sympathy and leave that to my psych. A less serial problem is my 2.4ghz AluMacBook. It's super great funtime, number one! The problem is when I put it in my laptop bag, the lid pops back open! This means pencils or cd's could get inside of the clamshell and damage it! I don't like to have my properties damaged so I'm wondering if there's a way I could re-tension the spring or adjust something soez that it stays shut. No, I'm not complaining about a weak spring, as with the MacBook Pros, I'm complaining about maybe a spastic spring that just can't be subdued. Is there any chance the magnets that hold it shut are weak?
My mid 2007 macbook pro thinks its asleep when the cover is open but awake when the cover is closed. I was encoding some media files to dvd when a friend accidentally unplugged the power source. The battery drained and I did not notice until it was fully drained. I then went to plug it in and turn it back on and it refused to, I then closed the cover and it awoke as if everything was normal. I opened the cover and I saw it exactly as it should but then the screen went black as if it had gone to sleep. i'd rather not have to purchase a new macbook.

MacBook Air:
Runs OS X
I really can't think of much more than that for the Air. I love OS X and thats why I haven't bought either. Mind you this is ignoring that Apple may release an update soon for the MBA cause if they do then I have my answer. But if they don't I don't know which I want! I love aluminum, but I am not a fan of the rounded corners apple put on the MBA.
I just have a quick question. I'm ordering a Macbook Pro this weekend and saw that one had a little beefier 512 MB of RAM instead of 256 dedicated for the graphics card.
I really hope Starcraft 2 isn't too graphic intensive and that the 256 would be enough to handle it. That's really the only game I plan on buying to play on here.
I currently have more HDs than my 09 MP can accommodate (already have 1 in the 2nd optical bay). Yet I keep one of the 4 bays as non essential, in case I have to troubleshoot a HD for either myself or friends/family. I also have a eSATA docking station, that is plugged in using an eSATA Sil3132 card. If I have to troubleshoot a problematic hard drive, does it make any difference if I mount it in one of the 4 internal bays, or using the eSATA dock?
I have a house that is not ideal for wifi. In particular, my office is an extension off the kitchen which has a solid brick wall between it and the rest of the house. Through 2 airport extremes, i get great wireless N signal everywhere in the house except this office. So, i added a 'N' airport express at the base of the stairs to this office and 'extended' the network.
So, i have 2 macbook pros up here. One is running on batteries, sitting on my desk, lid open. It is showing a rate of 108, signal -66 and noise -88 in the advanced wireless clients section of the airport express which it is getting it's signal from.
The next is closed and connected to a LED 24" cinema display. It is right next to the other MBP. It is showing a rate of 41, signal -80 and noise -93.
Why such a huge difference? Would it be because the lid is closed, it is connected to the display or a faulty macbook?
For almost the last year I have been using an Airport Extreme on 2.4b/g and and Airport express in my room to extend my wireless network. I also have a usb hdd configured to back up my macbook using time machine. Well I have a new roommate moving in and he has his own extreme and two expresses.
I have some questions on what would be the best way to consolidate our networking devices. I considered us selling our extremes and getting the new time capsule so both of our macs can use 5ghz while my girlfriends dell uses the 2.4.
Is there a noticeable speed difference between time capsule backup vs hard drive to extreme connected via usb?
