Turbo2/PC Alert III/ Adjustable Low Fan Speeds?

Anybody getting low RPM adjustable fans to register in PC Alert III?
I have adjusted the fan speed alerts on CPU and chassis to min, and still can't get proper fan RPM reading. Am guessing fans are about 1/2 speed (given the amount of adjustment I made), or about 1500 RPM. Now getting red 5 digit fan speeds and case temp jumping around.
Am not asking so I can stare at fan speeds, just to see changes in any adjustments I might choose.
Still loving the low dba of my 2 Enermax fans!

Just got a new case and some gadgets...My Thunderbird 1400 now idles at 42 degrees celsius. Overclocked to 1600 it idles at 42-43, under full load @1600 it doesnt go over 43.
In my old case i had 8 case fans, which made a whole lotta noise, so with this one i wanted it quiet. I put four 80mm case fans in (two front, two rear) and a 5 1/4 drive bay temp monitor/fan controller to run them. When its idling, the fans dont run, just the 5000rpm cpu fan, video card fan and thermostatically controlled psu fans. So its almost silent. When its under load, and the temp hits 43 degrees c. the fans kick in until the temp drops back and they switch off.
Gives the best of both worlds really, when im browsing or downloading or doing basically anything that wouldnt put enough load on the cpu that it needs extra cooling its quiet enough to be unnoticable, but when im gaming the fans kick in to keep the system cool. Since i usually either play games with the speakers cranked up (during the day) or use headphones (at night) i rarely even hear the exta fans spinning...
I picked up a motor speed controller kit yesterday, which i havent built yet, but will use that to control a 120mm blowhole and two 80mm side fans, so i can have them running all the time at around 1000rpm (quieter than the psu) to just give a slight breeze through the case, meaning the front and rear fans should only kick in after a lengthy period of gaming or benchmarking.

Can you adjust the fan speed? How?

I had an espiode the other day where the MacBook got so hot that it basically shut down. Can the fan be adjusted and how do I get to the area to adjust it? I am fairly new to the world of MacBooks and would appreciate the advice.

You can easily adjust the fan speed by using smcFanControl:

That said, it sounds a bit strange that the MacBook would run so hot. The fan should adjust itself to the CPU warmth. If that is not happening, I'd investigate whether the fan really works.

K8N Neo4 Setup - Issues Adjusting CPU Fan Speed - Alarm Going Off

Building this PC for a friend, and I just got it to post. Everything seems to be running stable, only when I get into the CoreCenter, the CPU Fan alarm is going off and the speed is flashing red. It is currently running at about 820 RPM, but the CPU temp is sitting at 37'C and the sys temp is 32'C. Is this too hot, is the fan speed way too low, I'm somewhat new to this. I set it to Cool'n'Quiet and it still does it, I disable Cool'n'Quiet and try to increase CPU fan speed manually, and it won't increase. Any input would be greatly appreciated. The rig is setup as follows;
MSI K8N Neo4
AMD 64 3000+
Kingston 512MB DDR400
80GB Seagate ATA
nVidia GeForce 6600GT 128MB
Antec NeoPower 480W

You can adjust the alarm level by clicking the little red arrow(Hardware monitor option) on the right side of Core Center, move the slider for CPU Fan Speed Alarm to the left(set it to 500-600rpm), and click OK.
Now you shouldn't get alarms any more.
The fan speed and temperatures you report are very similar to what I see on my system at idle. The fan shold begin to run faster if the system is under load for some time.

Hot computer... low fan speeds.

I saw a lot of questions here about fans running at full speech and being too loud. I have the opposite issue. I just moved into a new place, and I've had 3-4 freezes due to thermal issues. I have been monitoring the temp, and my processors get too hot. My A processor on my dual 2 gig G5 runs consistently in the 70s C. 76, I think, is the cut off temp.
I installed iStat pro which shows me my fan speeds. No matter how hot my computer gets, they stay at the same speed. The weirdest one is the rear fan which consistently stays at 51 RPM. The others hang out at 300... which isn't even close to max.
I don't think it's an isolated fan issue because it's all the fans and not just one. I don't think it's a sensor issue for the same reason.
Right now, i bought a fan and I have it blowing right into the front of the computer. My processors stay in the low 50s, so I know that if the fans were running properly, my computer would be plenty cool.
Does anyone have any idea why my fans aren't running right? And is there anything I can do to fix this myself?
Thanks,

I have cleaned out the inside... it is pretty much dust free. Would software cause the fans to not run correctly?
I don't have the hardware check disk... I don't think I ever got one. Or it got misplaced. I have the original install disk... but not a hardware check. Ah... it is on the install disk. I just had to read the instructions!
Just for fun, I'll install a fresh OS X on a spare disk to see if that works. It's an interesting idea.
Thanks for the responses... I'm just wondering why this is an isolated thing... a rear exhaust fan running at 51?
I'll also check for another utility, but when I open the side panel, and listen... it's easy to tell that the fans aren't working too hard.

Hight temperature, low fans speed. A problem_

I have a problem with OS 10.8.3 on macbook pro retina 15.
When temperature increases, above 75°C, I notice no change in fans speed, not increase.
Only with a external program (the smcfan control) is possible to increase speed and decrease the temperature.
Anyone else have this problem?

The first thing you should do is to reset the SMC > http://support.apple.com/kb/HT3964
If it doesn't work, you may have a hardware problem, so connect your computer to a power source and run Apple Hardware Test > http://support.apple.com/kb/ht1509 To start in Apple Hardware Test, hold Option (Alt) and D keys while the Mac is starting.
Then, select your language, mark the option for extended mode and start the test. If you see an error at the end of that test, copy it here. Make a backup of your computer and take the MacBook Pro to an Apple Store or reseller to get it replaced or repaired

Thinkpad T430u low fan speed

Hello!
When I am playing on thinkpad t430u CPU/GPU becomes very hot (95-100C), but fan speed is only 3000-3500 RPM. Using "tpfancontrol" I achieved almost 5000 RPM at manual mode and temperatures decreases to 70-75C.
Why fan is so slow at auto mode?
I updated BIOS, but it does not help. Moreover in BIOS there is no fan settings (quiet/performance) as on my old PC.
OS: Windows 8, Nvidia GPU, latest drivers.
Thanks!

Hi!
During normal working (word, firefox etc..) temp is around 60-75° with the fan always running at 3800rpm.
While I was doing a map upgrade on my garmin navigation system the notebook crashed many times in a row and I couldn't figure out why.
After some investigation I found out that it was the system overheating protection shutting it down.
I checked this by putting stress on the cpu with prim95 and there the temp goes up as I described in the previous post - just faster than weith the map upgrade. Ambient was 23-24° C.
What just made me wonder is why the hell doesn't the fan speed go up like it once used to do!?
I would expect the fan speed rising at around 75° or so but instead it started at 95° C which way too late!
This is my 3rd Thinkpad and I never experienced this behavior - however I am not sure when it started.

CPU load LOW - Fan speed HIGH - WHY ?

Hi
I'm watching youtube videos on my mac - under Windows XP (bootcamp) - I'm monitoring my CPU usage while watching the videos because my fan is spinning at full speed - yet the CPU is not working hard - about 5 to 10%. Does anyone know why the computer is getting hot and fans spinning faster if CPU load is still very low? Is it possible that I only see one of the cores in the windows monitoring system? I press control alt delete to access the info.
Any suggestions would be helpfull
Thanks

Hi tcdm1972,
A lot of postsfrom fellow users report their fan kicking out loud mostly when watching or using application that related with video or streaming video.
I'm not an apple tech, so I guess that fan also try to cool down the GPU chip sets since it is dinamically adjusted in and out of allocated memory and rendering or streaming video to the screen and become hot as well. (I could be wrong).
And most of the time the fan kicking when macbook plugged with mag safe (processor runs optimal clock speed).
Hope other user have different opinion.
Good Luck.

Satellite C850 - Low fan speed after BIOS update

Hello,
So I have my Satellite C850-PSKCEV bios updated around 6 months ago to version 6.80 (I bought my laptop in 2012), and since then the fan is running at low speeds and will never run full speed as before, and as a consequence the laptop overheats prematurely and very fast, and even when the laptop is not in use but left running it does overheat, also gaming is not even possible as any game that I run (even with the lowest settings) gets a fps drop every 5 seconds and lasts 5-10 seconds which renders even the lightest games unplayable, also I am afraid of the continuous overheat to damage the laptop's internal components.
I did clean the fan and vents from dust and there is not even one particle inside them and yet the fan won't run fast and I can't feel but very slight airflow from the vents as apposed to the strong one before this problem.

Hi
Have you tried to change cooling method settings and set it to maximum performance?

My 2006 iMac has begun to run hot which often causes issues. How can I adjust the fan speed with supported software?

24-inch iMac (2006) funning hot. Used "power button while turning on" trick to cool it so we could load some software which was telling us it was too hot; it was also smellong like it was going to burn up on fire one day while running a slide show for an hour. Need to figure out how to un-do the constant-on fan and need to find "supported" software that allows me to vary speed.

There is one called smcFanControl 2.2.2 released, but you really need to make sure that your iMac's air intake vents are clean and free from dust so that it is not sucked deeper into the iMac.
To clean the iMac's intake vent:
1. Shutdown the iMac and disconnect everything from it including the power cord.
2. Lay the iMac face down on a soft towel or cloth and go get out the vacumm cleaner.
3. Usinge the vacumm's brush or cravass tool, vigrously vacumm the bottom grill and small vent under the stand.
4. You also might want to remove the center RAM cover on the bottom and carefully vacumm it out without distrubing the RAM modules.
Then next before using smcFanControl, use the iStat Pro, a Dashboard Widget by iSlayer to first check all the sensor temp's and the speed of all three fans.
Finally if it is still having a cooling problem or you find that a fans has failed, you should stop using the iMac until the problem is fixed by an Authorized Apple Service Provider.

Unable to adjust fan speeds after OS X reinstall

Hi all,
I recently had a problem with Mac OS X on my MacBook Pro that eventually led to me reinstalling the OS from scratch. I erased the drive completely and did a clean reinstall using the Mac OS X 10.4.10 discs that came with the MacBook Pro.
Prior to reinstalling the OS, I was able to use the smcFanControl utility to adjust the fan speeds in my MBP as I saw fit. This was a great solution to keep a good balance between noise and temperature. I kept them running at 6000 RPM most of the time because I work on the computer at my desk most of the time. However when I take it to school with me, 6000 RPM is too loud to use comfortably in my classes. I used to be able to lower my fan speed to 4500 RPM, but since reinstalling, running smcFanControl will lock my fan speeds at the max (6000 RPM) and not allow me to lower them. Attempting to enter values manually tells me that I am attempting to lower the fan speeds below the minimum allowed value, but the fans are supposed to be able to range between 2000 RPM and 6000 RPM.
I'm not sure why an OS reinstall would break settings like these, but it appears that it has. Does anyone have any idea how I can reset the range of fan speeds back to what they're supposed to be?
Thanks very much!

Thanks for the reply. Sorry it took so long for me to get back to you but I finally gave this a try and it did not work.
I am currently using the Fan Control application you linked to (as I have been even before I came here) but the variables in that program don't allow me great enough control over the fan speeds. It is temperature-based, which I like, but the minimum and maximum values generally keep the fan speeds too low and the machine still too hot. I am using it temporarily but I much prefer smcFanControl because it allows me to set the fan speeds directly.

How can I adjust fan speed?

Hi; I have an HP Comaq Presario CQ57. The fan has gotten pretty loud; even when I first turn on the laptop and it is well ventalated in a cool area it is obnoxiously loud. Is there any way I can turn the fan off or adjust the fan speed? (I know it's risky so if you're going to tell me that please make sure you answer my question as well )

You can try a program called speedfan which is a free download
http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html
It's a pretty hard thing to use but it does give a readout of temperatures, which is useful even if you can't use it to adjust fan speed. Also go into the BIOS (F10) and see if there is a fan always on option and if so deselect it.
The fan is running fast for a reason. It is a symptom not a disease. Very likely the computer needs to be opened up and cleaned out inside. Post back if you want some direction on how to tackle that chore.

Fan Speed will not adjust/Too Noisy

I just installed my new MSI R6670 card. This card was reviewed as being very quiet but I immediately thought just the opposite. It sounds like the fans are running at 100% all the time overwhelming the sound of all other fans in my system.
The CD came with AMD's 8.84 driver so instead I went ahead and downloaded the latest 11.6 and included catalyst control center. CCC acted like it was adjusting the fan speed but there was no change in sound - like the fans were still running at full speed even though it said they were not. So I uninstalled CCC but left the 11.6 driver in place and installed MSI's Afterburner software. In the left hand pane it claimed the speed was set to Auto and currently at 44%. But in the hardware monitor section it lists the speed as 0% with occasional blips but mostly staying at zero. Turning off auto control and dragging the fan speed slider all the way to the slow side and clicking "apply" seems to have no impact on the sound and the hardware monitor keeps reading zero. Its showing the temperature at a steady 39 which doesn't seem excessive. Its looking to me like the software may not be able to monitor the fan speed so its just staying at 100% all the time.
Please help! I bought this card because the Radeon 6670 was supposed to be the most powerful card that would run without its own PCIe power cable and also because the reviews said it was very quiet. Right now it is anything but quiet!

I just pulled the card and disconnected the wire. They are definitely 4 wire fans. FYI Afterburner is crap as far as telling you what the fan speed is. When I put the card back in I left the wire disconnected and briefly started the system with the card running fanless. Afterburner still showed the fan speed as whatever the it was SUPPOSED to be running and showed the speed increasing with temperature, even though the actual fan speed was zero. So their software isn't even actually monitoring the speed. It is just telling you what the fan speed should be not what it is. Going through the threads on this forum, I'm seeing several others with different models of MSI cards having this same problem.

NB fan speed adjust with CoreCenter

Looks like it isn't possible to adjust NB fan speed with latest CoreCenter on a 865PE Neo2 with latest Bios.
CPU fan speed adjust works great.
Any help?

I've just tested Speedfan and this Program doesn't work also (and YES i've read the complete guide).
Is it a problem with the latest Bios 3.6?

Does MSI recommend manual adjusting of GPU fan speed using Riva Tuner?

My temp goes to 90c whe laying CoD4. Is it safe to adjust the fan speed with Riva Tuner? Bec. i think this is pretty hot. Or is it?

Yes its safe
"Bec. i think this is pretty hot. Or is it?"
No GPU usually is running hot, its normal. If you don't have troubles ignore the temp.

Automatic fan speed adjustment?

Currently I have the app SMCFan running on all of my Macs to regulate the fan speed in order to cool them down. And on all of these Macs I have different presets that control the RPM of specific fans. I have few different fan settings on my iMac according to the intensity of the task and the temperature of the hardward (I use MiStat to monitor my computers' temperature).
Here is the issue, my brother play games all the time and usually it drives the GPU and CPU up to 60-70C all the time and I don't want to turn my fan to maximum or over maximum the entire time including when its idle just to make sure it runs fast when my brother is playing games because: 1) it can potentially shorten the fan's lifespan, 2) it gets extremely loud especially on the iMac where the fan is gigantic. I can only go in and adjust the fan speed when I notice my brother is playing game via Screen Sharing from my MacBook Pro but I'm not always looking out for when he's playing games so there are times when the GPU shoots up to 70-80C and I won't know to adjust the fan speed.
For that, is there a way for me to set my iMac, or any of my Macs, that when the CPU or GPU activity hits a certain point (by % of activity or the temperature reading of the processor itself) it will increase or decrease the fan speed according to my settings automatically? If there is it would be extremely helpful to keep my iMac last longer.
Thanks ahead.

You are trying to fix something that isn't broken.
OS X controls the fan automatically to protect the cpu.
Third party fan control software is not needed and may, if configured improperly, result in damage to the cpu although an Intel cpu is supposed to shutdown if it gets too hot.
The minimum fan speed is 2000 RPM. It will start to increase around 70 degrees C.
