Applications :: Different Temperature Readings In IStat And Temperature Monitor?
Jan 4, 2011
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 downloaded and installed Temperature Monitor and iMac Fan Control - mainly for observational purposes and not for toying around with the fan speeds and I've got some questions. Mind you, I haven't tampered at all with the fan speed settings, just installed Fan Control. Here are my readings (while browsing the internet with Safari and doing a chat via iChat):
Fan Speeds: CPU fan (desired) 1300 RPM / (current) 1530 RPM HD fan (desired) 2100 RPM / (current) 2099 RPM DVD fan (desired) 1300 / 1298 RPM
I use iStat to keep an eye on the temperature of my macbook pro.
I noticed today that the temperature of my gpu diode dropped to -128 degrees Celsius. I decided that I should probably update my mac OS from 10.5 to 10.6. So I used my university's net install to install 10.6.
I updated iStat to version 2.0. Then I noticed that GPU diode does not even show up in the menu. Therefore I downloaded Temperature Monitor and the GPU diode still does not show.
However the GPU diode will sporadically show up. however, it has not shown up in a while now.
I can still see the temperature of the GPU heatsink however.
Does this mean that the GPU diode is bad? Or did the mac os X disable the reading of the GPU diode?
If the GPU diode temperature sensor did go bad, is there any problems with running the laptop without getting it fixed?
There isn't any temperature reading for my HeakSink A via iStat.And recently, my notebook's getting heaty easily. Could it be the malfunctioning of the Heatsink A that cause the abnormal temperture.Should i sent it for repair?
I'm fairly new to Macs so I am not quite familiar to what applications are out there that are available to me. The thing is I am currently using widgets in my Dashboard (iStat Pro and Temperature Monitor) that monitors system temps, but the problem is it tells me the temperature of what my MBP is at that moment. I want to know if there is a program that can take the max and min temps so I can keep track of how hot/cool my MBP is at all times.
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'm currently using Early 2008 Mac Pro and the ATI HD2600XT which came with it. When I use the ATI utility or GPU temperature monitor apps like GPU-Z on bootcamp (Windows XP SP3), the temperature is about 87C on idle, and goes to like 93C when running benchmark softwares. (I ran the Final Fantasy XI benchmark software). I know this is hot.
Do the GPU temperature monitor apps give accurate temperatures? Or are the temperatures displayed wrong? Because I noticed that the temperature for the CPUs are displayed higher on Boocamp than on Mac OSX.(Used HWMonitor on Bootcamp and Hardware Monitor on Mac OSX). And I have a question for the people who use or have used the Early 2008 Mac Pros and the ATI HD2600XT with it. How are your temperatures?
My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.
I've seen several posters talk about the temperature of their GPU. I have iStat and that shows my my processor temp, but is there a way to learn more about what the graphics card is doing? I have an ATI, so Zeus won't work.
So recently my 2008 Macbook Pro has been getting really hot, even when it's not really being used. It's now too hot to put on my lap and even sitting on a desk it doesnt get any better, and I am only running Chrome and iChat. Here are the Temp Monitor and iStat Pro sceenshots: I feel like it's been getting progressively hotter over the last few weeks, but what do I know. Also, why are the fans at 4500 rpms when Im only running chrome and iChat?
So I recently bought myself a Macbook Pro 2006 Model 15". And the idea was, buy it second hand and get the fan fixed totally the price of 600$. Which is great, because it works and things are fine.
But why is it that when I'm on Facebook on either Opera or Safari? My temp hits 80c. I've called up the Mac Store here in Ireland. They asked me to use iStat Pro to find out my temperatures. So I have, and all my temperatures are fine (around 30-50c) but my CPU temperature is hitting 80c.Honestly, this is quite scary to see that a computer I've bought hits 80c when I browse the internet?
Specs: Mac Os X 10.5.8 Processor: 2GHz Intel Core Duo Memory: 2GB 677MHz DDR2 SDRAM Macbook Pro 15"
I'm getting fed up with dealing with the Mac Store, if you guys know what I need to do to fix this problem? I'll open it myself, and fix it.
I have just brought the 1.8GHz + SSD version. It's really fast and quiet, until the fan spinning like crazy.
What is the acceptable CPU temperature on the Air?
Mine got up 89 degree C (192.2 F) MAX for a while, when the heat-sink is at much lower temperature, like 60-ish. Can't remember what tasks it was doing. It's 54 right now just with the Websites running, and the heat-sink is at 43.
Is it normal? Or should I worry about the thermopaste on the machine?
I happen to have a Late 2007 MacBook Pro (The specs are in my signature). My model was also the one affected by the 8600Gt issue so I had taken to a nearby Apple Reseller in Dubai in 2008. It's been months since that happened.
However, I've been monitoring my CPU & GPU temperatures and I'm still confused about what is ideal and if I should be worried about anything.
(I took a screenshot of my iStat readings and there's a difference of atleast 11C between the GPU Diode and GPU Heatsink)
Is there anything alarming that I should be worried about?
I'm using SMC Fan Control and it constantly hovers around 55-58 degree. Once it hits 60's the fan will bump to 6000+ rpm but will not drop. Even with light work load (Firefox, Adium, iTunes) temperature doesn't drop even when the fan is at 6000rpm until I close everything. Is this normal?
I've got one of the older white macbooks, and recently my cpu temperature has been spiking up to about 90 degrees celsius when I do things such as run online games or stream video from online. I don't think it ever used to do this before. Could this be a problem of stuff getting clogged in the fans? Or is it something else? Or, is it normal?
I just bought a MacBook Pro, i love it however i'm a bit worried about the temperatures, it usually runs at 60 degrees celsius when i start to load the computer a bit with 4 tabs browsing and a 3D App it gets to 70-85 degrees? is that normal or is it a lot? i just want to keep my new mac Healthy. Also, the RPM at 80 degs is around 3000 - 4000rpm
I see people stating the temperatures of their MBPs, fairly often in this forum. How do you do that?
By the way, I got my new 17" i7 MBP, yesterday, and it runs noticeably cooler than my 2006 core duo 2.16 MBP. Nonetheless, I'm still curious what the processor temperature is, and curious how you measure it.
I know iStat Pro and iStat Menus can monitor the CPU temperature, but I was wondering if there's any way to monitor the GPU temperature. I've been playing StarCraft II, and my CPU temperature has been getting to 80, which I guess is common with MacBooks, but I want to see if my GPU goes critical.
I just upgrade my mac from a T2300 to a T2600, I applied the thermal paste pretty good but with the heatsink just having 3 plastic pins that hold it down instead of 4(one broke) im kinda worried about it overheating. It's been running great for almost 2 hours now (while installing the mac os x disc)....well is there a way I could view the temperature of the cpu (instead of waiting for my mac to shutdown unexpectedly)?
Just upgraded my macbook pro from Snow leopard 10.6.8 to Lion 10.7.2, after upgrading I instantly installed the software updates and now my version is 10.7.4. However the i noticed the computer was getting hot fast and im sure its not a problem with the indexing and spotlight because that finished hours ago. Please help, do not want to melt my computer down. Before on snow leopard istat detects my temperature as 30 degrees celcius to 40 when im just surfing on firefox, now on lion istat shows 60-70 when only firefox is open and 50+ when nothing is open.
Does anyone know of any web sites that compare temperature differences between the i5 and i7 cpu's used in Macbook Pros?I am still on the fence on if I should get the i5 or i7. I don't own a Mac laptop now and have heard that they get quite hot. I am wondering if the i5 at the lower clock speed would run cooler.I have poked around on google with no luck. Anyone have any insight?
I'm currently running an all new MBP 13" at 2.66 GHz. The tests I made today (large textures handling in 3D environment, OpenGL, music playing in background) gave me an internal CPU temperature as high as 83*C. Should I worry about this? What is the max temperature a Core 2 Duo at 2.66 GHz should tolerate, in a MBP? I need to know because I'll use pretty often the laptop to do some "heavy" 3D demonstrations, in front of a classroom. I don't want the MBP to be prematurely damaged by heat.
