Way To Show Just Ambient Temperature Sensor Reading On An IMac?
May 12, 2012
Is there a very simple way to show just the ambient temperature sensor reading on an iMac? Not for geeky or engineering purposes. Just to know the temp that the machine and the human are in. iStat widget shows it but really tiny, buried in all the other data,and only if you launch Widgets.Ideally, it would just work in the background and the temperature would show up in the menu on the right side. Maybe next to the time. Alternatively, as a little floating window on the desktop.Yep, just want to see the room temperature using the iMac thermometer.
[URL] I went here. I have found out the iMac is a 2nd gen iMac G5. It has an ambient light sensor. I put my hand over it and it doesn't appear to actually do anything.
What is it supposed to do?
Do new ones have it? I have a 20" aluminum one as well, but don't see a sensor.
I've been using my mum's MPB C2D quite a bit, in anticipation of my own i5 arriving, and one thing that gets on my nerves is the ambient light sensor. It seems to be really sensitive, to the point where it will change the screen brightness when there has been no real changes in ambient light. If you move your hand over the sensor at the top of the screen, or even if someone walks past and casts a shadow it can change for a few seconds. Also, just moving the laptop around and the sensor changes the screen.
Obviously this setting can be turned off, but I'd like the feature if it wasn't so sensitive. Other than that, I love the MBP and can't wait for mine!
As of today, I noticed my ambient light sensor doesnt seem to work. I tried disabling and re-enabling it in system preferences, but that hasn't done the trick.
Is there some test I can do to see if it's working or not? I know it worked two days ago, because i took the i7 15" MBP outside and it automatically switched to max brightness. Today I took it outside and the brightness didn't switch at all and I couldn't see the screen it was so dark.
Since the last time it definitely worked, all I've done is install Windows 7 64-bit with Boot Camp and hooked up the MBP to an external 20" monitor with a minidisplay-DVI adapter.
I've had this new '13 rMBP for a little over 2 weeks now, and I absolutely love it! One small problem though, the ambient light sensor seems to not be responding, at all???
I've noticed that the ambient light sensor in the MBP can be somewhat sensitive. Sometimes an action as simple as moving my hands up to the keyboard (from the side) triggers the "auto-dimming" feature of the screen and it slightly reduces the brightness of the screen, then quickly returns. This is rather bothersome.
I've got the option under Keyboard and Mouse "Illuminate keyboard under low-light conditions" unchecked, but the screen still dims if you cover the speakers. I've also got the option under Energy Saver "Automatically reduce the brightness of the display before sleep" unchecked as well.
I'm at a loss here. Is there not a way to disable this auto-dim feature? A Google search didn't turn up much of anything. Surely there must be a way...
I could just by the replacement fan and swap it out but I am wondering if there is anything else that could be malfunctioning and causing the fan to NOT spin up - anything I can check before forking out the cash.Is there a way to see if the temp sensor is working? Could it be the LB? Can I test the electrical supply to the fan by using a multimeter? If so what setting/voltage, etc should I use to read that? And lastly, is there more than one fan?
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?Â
When trawling through the ridiculously long thread showing pictures of peoples Mac setups, I noticed an awful lot of ambient lighting and want to try a little myself. It's a painfully wanky thing to do, but with the iMac in the living room there just isn't any room for an ordinary lamp so a blue LED could look stunning.
What do people use for ambient lighting? It seems to be that, with USB ports being in fairly good supply behind the iMac it would be criminal not to go with something USB powered.
I found this: [URL]
Looks like it might do the trick, and even comes with a suction cup which *might* attach to the back of the iMac or the stand. The same light is also available in white, red, green or a colour changing version, but I'm convinced blue is best.
So I've done all I can find on the internet on helping my broken computer. It used to have the noisy fan issue and then it would shut off. Now after being off for 12 hours, it may shut off in 2 minutes, maybe in 30. I have reset the SMU by unplugging for 10 seconds and then plugging in while simultaneously holding the power button, then turning it on. Ive also reset the PRAM, but it still seems to shut off. Is it a bad power supply? I dont ever hear the fans blowing hard anymore.
If anyone has basic things to do, I'm all ears. I know last step is probably just reinstall OSX.
At times my computer runs very slowly. The activity monitor shows a lot of reading and writing, but not what is doing it. Is there any way to tell what is slowing things down?
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've recently installed a Crucial M500 512 GB SSD into my 21.5" 2011 iMac. I've done this to quite a few iMacs, and am well aware that some have a temperature sensor on the factory-installed hard drive. This one, however, did not, and now that the SSD is installed, I'm getting constantly running fans.Â
The fans run whether it's booted from the internal SSD, an external FireWire HD, or even if it's sitting in Target Disk Mode or on the Boot Options screen, so I feel like it's hardware-related.Â
Looking for a recommendation on temperature widget. This new i5 is too hot to the touch on the top. Well I could hold my hand there but it is not fun to do so. So I want a good widget/etc that will give me an idea of how hot it really is. On a side note. I cannot hear the drive or fans in my new i5. For wow players, all options (including full shadows but no full screen bloom), it bottoms out around 27fps in heavy effects environments or fast spin in busy Dalaran.
Peaks are beyond refresh (in fact I may want to cap that). After a three hour session the top portion of the aluminum enclosure was too hot to keep my hand pressed to it so I am looking for something to convince myself I am not going to end up with a cooked iMac in a few weeks. Since my desk is in the center of the room there is no problem with air flow but I don't want to have to run the ceiling fan.
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've been using intel iMac core2 duo. There are some temperature sensors to HDD, CD/DVD and CPU, etc., I think. Apple computer is well designed for thermal control and is this big advantage for technical point of view ?
Been using my imac lately and I've noticed a drop in wi-fi signal. I checked iStat and it said that the airport card's temp was 62?CIs the high temperature linked to the loss in signal?
My iMac is really hot! That is, when I run my hand across the outside of the machine, it is warm all over, and the entire upper portion of the back is what I would call "hot" to the touch. That is, I can place my hand there for a while, but it is uncomfortable. Is this normal? I suppose there is a specification for case temps. In a more analytic vein, iStat Nano shows component temps as follows:
I just wanted to share what's been going on with my i7 which I received last Friday. Immediately I was curious about what sort of temps I was going to be running so I installed Temperature Monitor. At idle my graphics readings hover around 40C. However, when playing Warcraft 3 my Graphics Processor Temperature Diode reaches up to 84C.
I don't really know what temps are acceptable, I was just wondering what other i7 HD4850s out there are running. To deal with this seemingly high temperature I installed smcFanControl and boosted all fan speeds by 50%. Noise doesn't seem to be proportional to fan speed at these levels so no probs there. Now I run at 64C at load and I am at peace with that.
Shouldn't the OS be increasing fan speed on its own?
Would like to know what you guys think and observe in your i7 machines
I just recently bought an imac computer and my two friends who know a lot about apple computers thought that the fans and temperature might be a little high. The cpu fan at idle runs at just under 1200 rpm's, the harddrive fan runs at 1100 rpm's and the optical drive fan runs at 1000 rpm's. The temperature itself 40-44C. The other imac that they know of is a year old, so we weren't sure if there were newer upgrades that might be making the difference between our speeds and temperature compared to that one.
Does anyone know the maximum operating temperature inside the new 27-inch iMac? I've read that they shouldn't be operated beyond 35 degrees Celsius [95 degrees F]. But that's the ambient temperature, not the computer's internal temperature.
I ask this because I have been running iStat for years. It monitors various things, including internal temperature. I always keep an eye on this during warm days, even when I have the air-conditioning on. So it would be good to know the maximum temperature.
it kind of just happened suddenly but my new aluminum iMac can not read CD/DVDs nor show them as an icon on the desktop. I don't know if this matters but it stopped reading them shortly after I preformed a mount with toast titanium on a mac universal binary image. Also, if I put a disk in, it thinks for a bit, then spits it out. I think I may have shut down the computer without dismounting the image and I don't know if that may contribute to the problem.
I have Windows XP installed on my iMac via Bootcamp. When I use the DVD Drive to copy data to my hard drive, the whole computer seems to go into slow motion.
I'm in Device Manager and under the Advanced Settings of my Primary IDE Channel, the Transfer Mode is set to PIO, which I hear it shouldn't be? Should changing this setting to "DMA if available" correct the slow transfer speeds?
I placed a Hoyle card game disc into my Mac Mini and it does not seem to be reading the disc and now I do not know how to get the disc to eject. Before I just had to click on the eject icon at the top of the screen but it only says super drive in light grey. How do I get a disc to eject?
I have experienced a main 320GB hard drive failure in my 24" iMac - which isn't as bad as it sounds as 1) I was considering an upgrade anytime soon anyway, and 2) I have a fairly recent backup. I am taking it to mac repairs tomorrow in Manchester so they can replace it with a 1TB drive - however, I want the original hard drive back on which I am planning to take the most recent data off it that wasn't backed up - so was hoping to shove the damaged SATA drive into an existing USB enclosure, plug it into my new iMac, fix any damaged areas on the drive, then restore what data I need (if retrievable)
But, a colleague has told me tonight, that I can only do that if the enclosure has a Firewire connection - I won't be able to achieve it with a USB connection - can't see why, but can anyone confirm if that is correct? - he seems to think it's something to do with how Disk Utility reads from a drive, the security on the drive, and the file structure but he wasn't sure!
