Fans and Temperatures

I've not long bought an "old" MBA --- 80 GByte disk and micro dvi.
Recently I've been noticing that, even when the thing is basically
idle (just me tapping away in an editor), the processor gets pretty hot
(getting towards 70 C) and (if it's connected to the power)
the fan starts whirring like mad (6200 RPM).
OK, I know the old MBAs struggle with video and the like. But
this is with just me typing and maybe a couple of (animation free)
web pages. That shouldn't need the fan going at full speed.
((Especially when, if I unplug it from the power, the fans slows but
the CPU gets hardly any hotter!))
Now, I've just noticed that although iStat is telling me
that the CPU is currently 68 degrees, the heatsink is only 56.
Is that right? Should the heat sink be that much cooler than the
CPU? Or is there a problem?
Could someone tell me what sort of temperature difference THEY get
between CPU and heatsink?
Thanks in advance.
Robert.

Greetings,
What web page causing your air running hot? It might be the network problem. When i'm listening online radio when the network speed is sluggish (especially in my school), my air turn out to be running hot.
How about turning airport off? Running hot as well?
In fact it is very hard to judge what causing your air running hot. Sometime it might be "windowserver", "VshieldCore" or some funny program like that.
Go to activity monitor (all processes) and check out which program causing your cpu running high.
Good luck.

Fan and Temperature Issues with certain apps

Hi there
I have what seems to be an issue with the cooling on my 2011 Mac Mini where when running some apps the cooling fams for the CPU seem not to kick in.
To give an example I do a lot of online gaming and when playing LoTRO on my Mini when the CPU temp gets to around 78-80c mark the CPU fan ramps up to keep the CPU cool which I guess is normal however yesterday I was doing some audio recording / editing in Garageband and noticed the CPU temp was at 93c but yet the fans hadn't kicked in.
I did a bit of research and installed SMCFanControl to monitor what the CPU fan was doing. Again using LoTRO when the CPU got to around 80c the fans ramped up to around 4800rpm and the temperature lowered yet with Garageband even with the CPU at 91c the fan was only spinning at 1800rpm. I know 90c is still below the threshold of safe operation for the Core i5 2415M CPU (which is 100c) but not by much. This is a real concern for me the hotter the CPU runs the shorter its life will be. It is unfortunate that SMCFanControl is unable to directly control the CPU Fan in the 2011 Mac Mini
Can anyone out there can shed any light on why this is happening?

Thank you everybody for your sound advice - Normally John Hammer1 I would agree with you, if OSX can do a task then let it do it and not use 3rd party software, but however in this case I don't think OSX was doing a very good job at cooling the system. To use an analogy you wouldn't drive your car with the temperature gauge constantly near the red line as it would damage your engine. This is how my MM was running when editing (of which I do quite a lot) and having a computer constantly running near its thermal limits isn't doing it any good.
I feel (and have always felt) that my Mac Mini has been lacking in cooling and that whilst the MM is a pretty little computer its performance has always been hampered by its lack of cooling. I'd rather have a bit more noise from the fan and have a more efficient computer.
I have installed Fan Control 1.2 and so far it is doing its stuff ok. Like den.thed I'm a bit old school, I usually keep my Macs for around 4-5 years and I want this one to last.
Again thanks everyone for your advice.

Fan and Temperature Issues

Hey everyone,
Recently my fan started getting pretty loud. I opened up the back of my 2009 13" Macbook Pro and gave it a through and through with a compressed air canister, I also unmounted the fan and shot some compressed air into it as well. Now I'm kinda worried, because that only kinda dulled out the noise a bit, and the internal temperature of my CPU is getting a little too hot for comfort(100 C and up). The problem isn't so much the temperature, but the fact that in response to these high temperatures my fan is consistently at a MAXIMUM of 1500 RPM according to SMC Fan Control. Even if, using SMC, I set the minimum fan speed to 4000 or 6000 RPM, my fan just stays at consistently low speeds. Would opening up the fan itself and cleaning/lubing solve the problem or should I just replace the fan altogether?
Thanks in advance

Im having a similar problem with my late 2009 Macbook (white). All of a sudden the fan has been acting up, making uneven and inconsistent whirring sounds. At first it didnt happen right away but now it pretty much starts acting up within 10 minutes of turning on. I downloaded smcFanControl and learned that at some points CPU was in the 90C range and the fan would jump between 0rpm to 1500rpm. I turned it off for an hour or so just now and it's been at a solid 42C and 1999rpm for about an hour now... like i said it's REALLY inconsistent.
based on what i read i guess i dont have to worry about the temperatures so much with this model? I havent gotten past 94C just yet.... Is the best thing to do just replace the fan? Im not sure that would even solve the problem and I'd like to be sure before i spend a cool (har) $100 on something that wont work.
Do laptop coolers help at all? Is there one you guys would recommend for this kind of thing? I just dont want this to be the second hard drive to FRY on me because of a lousy fan.
plus i'm a student, this laptop needs to last me at LEAST 2 more years.
thanks, any temporary fixes would be nice too.

Sound of the fan and temperatures.

I have the new macbook since a month now. I have installed iStat and I see that the cpu is something like 50oC while just surfing or listening to music and the exhaust fan works at 2001 rpm. Is it normal? How about yours?
At 2001 rpm the fan's noise is quite noticable.

I believe it is normal. 50 degrees Celsius is quite cool for a laptop. and your fan RPM is about where mine is and I do not hear it at all. I would have it looked at if it is really that noticeable.

Satellite L670-1JN - Fan activity and temperature

Hello,
When my Satellite L670-1JN is not in sleep mode and when no application is running (only OS) with an ambiant temp 20C at wich temperaure approximately must be the processor?
At which temperature fan start and stop?
Power mode selected is normal with optimization of performance, with the power adapter.
Thanks

Yes fan activity is control automatically but when my laptop is not in sleep mode and when no application is running (only OS) fan stop(30s) cpu temp increase from 36% to 40% and fan run(30s at 55%) temp decrease from 40% to 36%.
For this I used Health Monitor delivered with PC. Temps ig given in % so i can't know temperature in C.
Is it normal? ambiant temp is 20C.
It's noisy.
I will prefer to have fan continuously on at lower speed.
Is it possible to change setting of fan and temperature except by changing the cooling method in Windows Power Management to battery optimized.
In this case noise increase fan stop(60s) cpu temp increase from 32% to 40% and fan run(60s at 90%) temp decrease from 40% to 32%.
My PC is newer I have not yet install other application so only OS is running.

My macbook pro i7 (2011 version) has a loud fan and high cpu % when I have Skype on or when I am on Safari. Help please!

My macbook pro i7 (2011 version) has a loud fan and a high cpu % when I have Skype on or when I am on Safari. My laptop would sometimes freeze for a while and it is usually hot. Has anyone else encounter this problem and know how to fix it? Thanks!

Skype is a very resource intensive activity...it has been reported on here users are seeing cpu temperatures on the order of 80-85 °C, within the limits of the cpu, but still hot to the touch.
Make sure nothing else is running so you keep the thermal load down.

I want to quiet down a P4 1.6A CPU fan and Sparkle PSU

Hi,
I want to quiet down my P4 1.6A CPU fan and PSU fan....
A) I have a MSI 845G-MAX-L motherboard with Winbond monitoring chip. I notice that the CPU fan RPM goes up when temperature goes up. Is this normal on all boards, or is this an extra nice feature specific to MSI boards with Winbond chip???
B) I've already put a FanMate to the CPU fan, and it runs at 1500 RPM, but I can still hear it.... so now I have a Zalman fan bracket (FB123) and am searching for a 80MM which has RPM sensoring, to give me some feedback in the BIOS and MBM5. Any suggestions on a quiet 80MM which has RPM sensoring.... (I've tried Coolermaster and Vantec.. they are both noisy to me.... I tried Panaflo but I want the RPM sensor so I can tell if the Winbond chip is doing it's job of speeding up the fan when the CPU temp goes up....
C) I have a Sparkle 300W-BTV PSU. Does Sparkle solder on the PSU fan tail to the pcb or do they use some pin header?? I'll probably replace the PSU fan with Panaflo. Also does Sparkle use a thermistor to control fan speed or is it just one speed? I can use the Coolermaster DAF-B82 which is quiet at startup (1000 rpm) at 20 C.
D) I am thinking about getting the OCZ P4 eliminator passive heatsink.... anyone using it or seen a review of it? Can the Alpha 8942 run in passive mode with no CPU fan? I only have the Sparkle PSU fan as the exhaust fan in my Coolermaster ATCS-200 aluminum case.
Thanks.....

My CPU runs at 37 C at idle and the CPU fan is at 2400 RPM. When running loaded (at 100% utilization after 1 hour) my CPU temp runs at 41 C and the CPU fan is at 2800 RPM. During the summer when ambient temps were very high I've seen my CPU temps at 43 C and CPU fan speed at 3000 RPM.
I read a little on the Intel Precision Cooling Technology. I believe that the Intel Precision Cooling is capable of adjusting the SYSTEM case fans (along with the CPU fan). It seems that Intel went one step further by adding in SYSTEM fans and then adding in the ability for the user to control both the CPU fan and SYSTEM fans based on temperature.
What I'm wondering is if all or most P4 motherboards adjust the CPU fan speed based on CPU temp (in real time), or is this just something new that MSI did in their later boards like my 845G MAX? Anyone have other P4 MB (other than the obvious ones by Asus and the ones which have the Intel Precision Cooling) who can comment?

Fan and flash website?

Hi there,
I am just wondering if your Imac G5 PPC's fan runs at full speed when you vist flash websites? Is it normal?
CPU temperature = 67 degrees
Hard drive temperature = 58 degrees
Fan speed
CPU = 4446 rpm
System = 2453
Harddrive = 2615
Please advice

I have an imac G5 with 1 gig of ram. When my daughter visits a flash website the cpu fan will ramp up to +5000 rpm. Apple has already replaced the logic board and the power supply. During those repairs I was told the fan noise was normal. The fans can get so loud that I can hear them over 30 feet away. Very loud.
I also have a Macbook Core Duo 2gh with 512 meg of ram.That laptop will never make a sound except for the dvd sound when watching a dvd. No fan noise, no high ramps on the fans, nothing.
I have read that placing a piece of foam insulation on the cpu fan housing will reduce the noise as it may be due to vibration of the fan and/or fan housing.

MSI AMD 890GX and Temperature Monitoring

Bear with me if this is a silly question to ask, this is my first computer build so I have a lot to learn.
I'm wanting to get a 5.25 in bay temperature monitor and was hoping there might be a port or connector somewhere on the motherboard to give me the bios reading of the CPU and/or northbridge temperature to external hardware. I, obviously, have the 890GX board and the Athlon II 3X but before I try any overclocking I want to be able to see a true temperature reading.
I've looked at a few fan controllers and temperature displays that have probes for their readings but I'm not fully convinced that readings in the area of the CPU or northbridge would be adequate, safety-wise.
Thanks

I have nothing against the BIOS readings, in fact that's what I'm interested in. My complaint about temperature probes is that its only going to give me a reading of the surrounding area rather then a direct reading of the cpu temperature.
I want to know if theres anyway to use one of the jUSB ports to connect to a piece of hardware to display the bios temperature readings. I'm sure this would involve a little bit (or a lotta bit) of coding to accomplish if its possible at all but I'd like to know if anyone has any information about hardware to do this.

How to locate HP fan and clean it?

I have a dv6 HP Pavilion Entertainment PC. The model number is dv6t-1200. I am trying to find the fan and clean it but I do not know where it is located. Also, do I have to unscrew anything to reach it? If so, where? Thank you for your response in advance.

You will have to take the whole laptop apart due to its crazy construction.
Blow the vents dust and do this instead:
Try this:
Hello,
I decided to sacrifice 1 percent (just) of performance for the sake of cool temperatures and silent fan. I have HP DV6, with AMD Turion RM-74 and HD4650.
So, Yes, You will loose up to 1 percent Your CPU power, but heyh, this processor is so fast that You will barelly notice the change. You will still watch HD content with 720p and everything else smoothly. Note, that gaming will be harder part but consider Your laptop not as a device created for heavy gaming.
However,
I rarely do play NBA 2K10 on my laptop. It is very cpu demanding. After I've done the above, my CPU temp never reached beyond 71 percent while gaming, GPU - 75 percent.
Without the above mentioned my CPU went over 100 and GPU over 90.
No more overheating.
So, how to reduce Your notebook temps:
(i) Power Options -> More power options,
(ii) Balanced plan -> Change settings,
(iii) Change advanced power settings
(iv) Processor power management -> Maximum processor state -> On Battery - 50 percent, Plugged in - 99 percent.
(vi) Save changes and close.
Now, mine temperatures are - idle 48, heavy load - 57, extremelly heavy load (HD 720p content) - 62-63. (At the moment my CPU cores are at 47 celsius).
And please note, that the notebooks coolers are just a joke and designed not to cool your laptops, but to take away your money. Their effieciency is minimum: -1/2 celcius.

FAN and display does not match.

hi.
i have a mega 180 and use the pc software "PC alert 4" to show info on the LCD. only thing is that it shows fanspeed between 2900rpm and 5400rpm without that i can either hear or feel any difference. and the temperature of the CPU has to go to about 75C before the FAN speeds up. and sometimes when the cpu is hot for a long time the fan gets stuck on high rpm so i have to restart my computer to slow it down.
now i wonder if a BIOS update will fix this? and how do i update my bios?

i use Arctic silver5 and i have applied thermal paste lots of times so i know how to do. it so thin that i cannot make it thinner without clearing the view to the CPU core.
and yes i have been thinking on reversing the cpu FANs and putting in an additional 60mm fan to blow over the discs and memory. but first i need a 4pin connector splitter so i can put in my other harddrive and then i need one more fan connector..
stupid MSI built in a SATA power cord when the 180 does not have SATA controller.

Fans and Z87-GD65 new build question

Hi. I am waiting on all my parts for a new build this week. I've only done one build before and that was over 4 years ago (i5-750 / MSI P55-GD65). My question is regarding fans and how to control them on the Z87-GD65 mobo. My case comes with three 140 mm 3-pin fans and a 3 fan 3-speed manual fan controller. I've never used a fan controller before and would prefer to use SpeedFan or the BIOS to adjust speed fans based on CPU/GPU temperatures. Will I be able to set up automatic speed control in BIOS or SpeedFan for all 3 fans with this motherboard? Or do I need PWM fans to do so? What if I want to install 2 extra fans? Any help would be appreciated!
CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor
CPU Cooler: Phanteks PH-TC12DX_RD 68.5 CFM CPU Cooler
Motherboard: MSI Z87-GD65 Gaming ATX LGA1150 Motherboard
Memory: G.Skill Sniper Series 8GB (2 x 4GB) DDR3-1866 Memory
Storage: Samsung 840 EVO 250GB 2.5" Solid State Disk
Video Card: Sapphire Radeon HD 7950 3GB Video Card
Case: Fractal Design Arc Midi R2 (Black) ATX Mid Tower Case
Power Supply: SeaSonic G 550W 80+ Gold Certified Semi-Modular ATX Power Supply

Those connected to the fan controllers are controlled through their buttons (or whatever to adjust the speed). Those connected to motherboard, are connected through a software, such as Command Centre (which in my opinion is great for this).
Not sure how many connectors do you have on the motherboard, but I think there's x2 CPUFan and x3 SysFan. That means you can have x5 fans connected to them. But you can either purchase a Y splitter which will let you connect 2 fans into a single socket (I am using one Y splitter) or just get proper fan controller.

Controlling CPU cooling fan and other cooling fans

I have not saw any answers to controlling cooling fans speed especially the CPU fan.
My new mid tower, HP ENVY 700 200z
AMD A10-5800K APU with Radeon HD Graphics
Motherboard: MSI 2AE0 1.0 w/UEFI: AMI 80.48 01/15/2014 8 gb RAM / Windows 8.1 (x64) (build 9600) / 1 TB Hard drive
I've looked in the UFEI/BIOS settings and can find no way to speed CPU fan up, the fan usually runs around 950 RPM and temperature avg is 50C the coolest I've saw is 47C/ fan 875rpm and sometimes peaks at 78C fan will ramp up to 1150 rpm. Motherboard, HD, video card all never hit 40c.
I consider this to warm would like to keep it at 30c-40c range. I still have my 1st mid tower Gateway and it still runs 15 years old, along with my ASUS mid tower 8 years and I was always able to control fan speeds and keep everything in the 30c-40c range, don't think the new ENVY CPU or motherboard CPU socket will take these very warm temps very well.
Anyone have any idea, or know a way to speed this CPU fan up? I have NO PROBLEM with fan noise and I am even considering buying another CPU fan that I can control the speed of, I'm not using this ENVY other than a business computer, no games period nor trying to overclock.
This is the 1st tower or laptop I've owned that has no user control over so much of its functions nor did not come with a User's Manual. It was like buying a brand new car and knowing what any switch, button or any indicator lamp was for. Did not have any trouble with W. 8.1 already had a Windows Phone and 2 laptops with W 8.1

Hello TDS777,
I understand you are looking to adjust the fan speed on your HP ENVY 700-200z CTO Desktop PC. Unfortunately, there is no way of doing what you are trying to do on your computer. I would suggest you do a Google search for "computer cooling systems" and you will find various ways of implementing a solution that suits you.
I hope I have answered your question to your satisfaction. Thank you for posting on the HP Forums. Have a great day!

Extremely noisy fan and burning motherboard

Hi, I got HP dv5 2070us laptop a couple years ago and decided to dust out the fans and stuff. So I brought my laptop to the computer service office to clean it.
After the clean up, my fan got even louder than before! Roaring like crazy.
So I tried to figure out what was wrong with it. Downloaded some software like Speedfan and Aida64 to check out the temperatures of the CPU, motherboard and so on. Both mentioned programs shows that my motherboard is 87C (189F) ! and this temperature is fixed, doesn't change all day long, while the CPU temperatures are changing.
Maybe this is the reason of the noisy fan. What is more, computer doesn't shut down. The screen is black but fans are working even after 10mins. The only way for a completely shut it down is to press the power button.
Does anyone one how to solve this problem?

Hello Merc,
Try figuring out what's causing the noise.
Is it a vibration? Try a mechanic's stethoscope if you can find one; or just use a thin, long bladed screwdriver to amplify the noise. Cleaning the fan blades of accumulated crud will improve their balance. Occasionally, sheet metal or a loose screw will pick up the vibration and amplify it.
Is it a bearing or bush that's starting to wear? Maybe it's new fan time - nothing is forever!
Is it the rush of air? They make quieter fans, although the quiet ones don't always cool as well. (I have a dual 800MHz Quicksilver that was fitted with a quiet fan, and you could have grilled bacon on the heatsink - I wound up with a high-powered fan that I can hear in the next room.... but a cool Mac!)
Try measuring your fan (in mm) and searching for fans; I don't remember my exact parametres, but I turned up quite a few. Compare using RPMs, dBs, and CFM as guides. Come back and make us all experts!
HTH ..... Jon

Fan speed & temperature

hello guys...
After 8 months before buying my geforce4ti4800se videogard, I began to notice some changes to fan speed & temperature while checking 3d turbo experience...
first of all, when I bough the card (winter season) I cant remember the fan speed but the card's internal temperature was about 39ºc while not playing and 45 ºc playing games... external temperature was around 15 - 20 ºc...
Now , card's temperature stays around 56ºC (without playing games) and jumps to 58 - 59ºc after playing games... Local temperature (32ºC) ...
I cant remember the fan speed at winter but now Im getting a blink message on the driver and the fan speed stays at 3300 rpm....
The increase of the temperature is related to a fan slowdown..? If YES, how can I fix the fan to get more speed? (Its not a source problem)....
Is 58ºC ok for the card or should I get worried about it ?
Help me please!! Thanks a lot,

Without full system specs in your sig line, it's very hard to help. Minimal information gets minimal help. Some people here won't even bother to answer w/o the info, and I can't say that I blame them, especially when the instructions are at the top of the forum.
To me, w/o any other info, it sounds like you have a case ventilation problem.
