Real time fan speed and temperature of the Thunderbolt Display

Is there software program that allows you to know the real time speed of the itnernal fan of the Thunderbolt display. Also I would like to monitor the internal temp of the TBD. I have Istat which allows me to do both but only for my MBPro not my montior.
Thanks.

Have you ever cleaned you machine? Since it's an iSight (which is actually 3rd generation, Ambient Light is the 2nd, Rev A the 1st), you can't open it but you can vacuum the air vents, which might help.

IMac (early 2009), 3.06 GHz, ATI 4850 - fan speed and temperature questions

Well, so 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
Temperatures:
CPU Heatsink: 92°F
Internal HD: 108°F
Internal DVD: 95°F
GPU Heatsink: 107°F
Are these, under the circumstances, normal readings?
Thanks in advance for your replies.

Your welcome and no problem. I would say only the Apple engineers can tell you why the fans are set to those speeds however my best guess is the obvious they found those speeds the closest to keeping the temps at an optimum operating temperature. I found when I'm doing graphics intensive work my machine heats up but quickly cools down when I'm done.

Increasing fan speed and temperature

my temperatures and fan speeds are slowly getting higher and louder on my imac g5 2nd gen (17", w/isight, 1.9ghz). i've never noticed my fans before. the only time i ever used to notice my imac made any noise at all was in the dead of night when i shut it down and noticed the absence of noise. but a couple of months ago i started being able to hear the fans when i play world of warcraft. since then, they have slowly gotten louder and louder, and they allow my cpu temp to get higher and higher before it stops rising.
before i could hear the fans i never noticed the temp, but after i started hearing them, my cpu temp usually maxed out at around 148º. now it is allowed to get to 167º and stay there while i play wow. and the fans are so loud i have to use headphones to be able to hear the game. simply surfing the internet now causes higher temperatures and fan speeds than playing WoW did a month ago.
should i take it to a service technician to see if anything is wrong with it?

Macbook Pro Retina Fan Speed with 3 vs 2 external displays

Hello,
When I'm in my home office, I often use my MacBook Pro Retina in Clamshell Mode (in a BookArc) with external displays.
Originally, I used 2 external displays (2x 1920x1800), and the fan speed and temperature remained stable at the lowest end of the spectrum (around 2200rpm and 60°C). However, recently I decided to use all the ports available and plug in an extra monitor (1680x1050) for that extra screen real estate. I can tell you that having three external monitors really makes a difference to my productivity. However, just by adding this extra display, the fan speed boosts up to a minimum of 4500rpm and often goes up to around 6000rpm. The temperature is also high (I guess the fan speed is a symptom of this).
I understand that the extra pixels in the 3rd monitor could definately tax the GPU more. However, I am suprised that the fan speed and GPU temperatures go so high, especially as all I am doing is moving around on a Preview PDF file, just from adding the extra monitor (especially with it's modest resolution).
I guess my questions are:
Is this expected behaviour for the rMBP?
Is this going to damage my rMBP with extended use (say, a good 6-8 hours pretty much every day for the next few years)?
Thanks very much,
Richard

I've managed to get the fan speed down to a reasonable, less audible level by using that old VRAM terminal command to enable me to keep the internal display disabled whilst the lid is open. I've had to shift quite a lot round on my desk to make this happen, but I guess it was the only way. It now runs 3 screens under similar loads at approximately 3500prm.
Taking your advice into consideration, I raised the rear feet and this enabled further decrease in fan speed. I guess one of those laptop stands will augment this effect, and I will look into them.
Anyway, thank you for your help!
Thanks,
Richard

Fan stop and go all the time on B590

Hello, since 1 week i'm trying to contact phone support in france , message says that somebody will contact me and i'm waiting for...(maybe nobody work???)
Well i have got problems about fan...my version is Windows 8.1, and my fan after few time when my laptop start begin to work around 1 or 2 seconds and stop maybe 10 or 1 minute...and again and again...
I try to install bios but it's not working (even if i take the good one..) , watch for the temp and nothing is strange...
Please help me...

Monitor fan speed and temps with something suitable like Temperature Monitor.
FBDIMMs create a lot of heat, the older ones more so (anything from 2 yrs ago or older).

MSI 5900XT-VTD Fan speed and GPU Temperature

Hello,
I wonder if someone can tell me how can i know the temperature and fan speed of my MSI Gforce FX 5900 XT-VTD.
I have installed 3D Turbo Experience (MSI utility) but when i get the window,i'm only able to see the Core and Mem Speed(I can modify them).The fan speed and core temperature are not active.....
Is it normal ?..

that card doesnt surport monitoring of temps and fan speed

I want to be able to tweak the graphic equalizer in real time while recording - and have this have the audible effect written to the recording. At the moment i have to go into post-production and manually set the graph equalizer at various time points .

This won't be real-time as you record, but you could tweak the EQ in real-time after the recording thus:
Record what you want to tweak into GB with no effects.
Solo the track and output it into something like Audacity.
Start Audacity recording, then play your track in GB as you make those tweaks. That's what Audacity will record.
Get that file from Audacity and put it into GB, then you'll have that effect.
Sorry if it's complicated, but that's what came to mind. Hope it works.

Fan Speeds, and Mirror Raid with New Internal Hard Drive

Regards,
I recently installed and formatted a new hard drive in my PowerMac dual 2.3 ghz computer and I have a few questions.
1. Now that there are two hard drives do I need to do anything to ensure that the fan on my computer can keep them cool? I think the fans I have in the hard drive bay is enough, but I do not know if they will automatically set themselves to run properly. I can monitor the fan speeds and temp from iStat pro, but do not remember what level the temperature was before installing the new one.
2. Given that my new drive is a SeaDisc hard drive and the older one is a Western Digital, will this cause any problems in creating a mirrored RAID. I believe that both are 7200rpm drives, and my second hard drive is a little larger (I will just have unused space after making the RAID). I am concerned with the fact that these two drives are from two different manufactures. Will this cause problems or drastically slow down the reading and writing of data? Has anyone else experienced problems in making a mirrored RAID from two hard drives that are not exact matches, and even come from different manufacturers?
Any advice will help.
Thanks
earpshmael

Hi earpshmael;
Generally when creating RAID arrays the more similar the drive the less problems you tend to have.
The real question is exactly why do you want or need RAID?
I think so many people seem to think that RAID will solve all of their problem. I hate to tell you the bad news but it will not.
Generally there are to varieties of RAID available using the software RAID built into OS X which are 0 and 1. RAID 0 or stripling is generally for moving large file rapidly for applications like HD video. It usually doesn't help the OS. RAID 1 or mirroring is for protection from drive failure. It is not a valid backup solution.

SIT Real-time data logging and passing data

Hello all,
I am pretty new to LabView real-time, so I just want to confirm a few things. I am also using the Simulation Interface Toolkit.
Let's take the Sinewave.vi from the SIT examples. I have modified it to use sinewave.dll, and run on PXI-8101. If my understanding is correct, when I click "Play", the entire Sinewave.vi is deloyed into PXI-8101, and therefore the entire VI is running at the same pace. The front panel I see on my desktop is slower snapshots of what is actually happening?
1) Let's pretend now that the sinewave model is time critical and must run every 10ms. How do I do that? I have noticed that within the "SIT_Indicator_Indices" loop, there is a Wait 50ms block. Is that accurate?
2) I have also added a time elapsed block that will change the Frequency and Amplitude inputs as a function of time. I made them update every 2ms. What clock are we running on? If my sinewave.mdl suddenly calculate integration (time dependent), can I use that elapsed time block as my timer to pass into the model?
3) How fast is the sinewave.vi running anyways?
4) Let's say I want a log of the sinewave output (a data point every 10ms). I don't need the log in real-time, I just want to do some analysis on it later. How do I do it?
Thanks.

Sine Wave.vi ‏104 KB

Hi Bladhart,
When running the in the Development Environment (pressing the run button on the Real-Time vi) there will be an extra thread to handle the front panel you see. This thread will be handled just like any other thread in Real-Time and will take processor time, thus slowing down your entire application to a certain extent.
1. You would need to make sure everthing inside the loop can execute within 10ms and change the wait time to 10ms. Or you can use a timed loop set to run every 10ms and get rid of the wait time but again you would need to ensure everything in the loop can execute in under 10ms.
2. The elapsed time should be running off the Real-Time system clock.
3. The time that the Sinewave.vi is running is system dependent, there is no set speed.
4. You can log the data by saving to a *.tdms file. You can then use the data from the *.tdms file to do processing later.

Why is my macbook air getting so hot, fan running, and burning through the battery fast?

why is my macbook air getting so hot, fan running, and burning through the battery fast?

I have started to experience my computer getting really hot also. Since one month back in time it has started to get raging hot (up to 99 degrees celsius) just by surfing the internet. Sometimes it stays that hot but most of the time the temperature gets lower after about 15 minutes..
this has never happend before and i am starting to get worried..
what is the problem and is there a sollution??

What are you using for Fan speed AND temp monitor?

Thanks to Bosskiller, my rig seems to be running a bit stabler now! Knock on wood. Is there any program other than MSI's core center that monitor fan speed AND temp? I used to use MBM but it's no longer being supported and CoreCenter doesn't seem all that popular here?

Actually how accurate is the temp reading on HWMonitor for your MSI board? One thing I noticed is that w/ Coretemeter the temp reading was around 48-50c on Rig#1 and almost 58-60c on Rig#2 (That's my HTPC w/ EXTREMELY tight spacings so still work in progress as far as cooling's concern!) but using HWMonitor I got 31c CONSISTENTLY on both rigs! I'll love to think that I'm indeed running this cool but feeling the exhaust air, I think this 31c reading is not real...

Real-Time Sequencer Feedback and Questions

Post your questions and feedback to the Real-Time Sequencer Architecture and Real-Time Sequencer Architecture Example here.
Brian K.

I just purchased the USB 6341 DAQ card. I am using Dev1/.Port1 to control 4 driver transistors. The transistors fire 4 SSR. I am trying to create a sequence for the 4 transistors. Sometimes a test unit that is driven by a SSR will fail. So I have to change the sequence for the failed DUT.
Basically each SSR will be ON for 6 seconds. There will be a delay of about 5.75 seconds for the next valve to fire. The delay is used to balance the pressure testing. The second valve will need to start at 5.75 seconds later. Basically the two valves must cross at the 50 % turn OFF. How can I perform this task. There are at least 7 different test sequences??

I suspect this is something that I am doing wrong (or is it a kernel issue??) as I have the same problem on a similar machine running Ubuntu 10.04.
Any ideas appreciated.

Is vision development module in labview 8.6. sufficient for real-time image acquisition and analysis using a webcam

Hi,
I'm new to labview and trying to develop an eye-tracker using labview 8.6. It has the vision development module and i was wondering if this was sufficient for real-time image acquisition and processing or would i be needing any other software tools.
Solved!
Go to Solution.

Hello, certainly it is possible and sufficient for real-time tracking!
About eye tracking - if you need an example, you can find the code here:
https://decibel.ni.com/content/blogs/kl3m3n/2013/10/08/real-time-face-and-eye-detection-in-labview-u...
The code uses OpenCV functionalities along with the LabView UI (and some other functions like overlay).
Hope this helps a bit.
Best regards,
K
