460GTX Hawk noisy at certain fan speeds

Hi everyone
I wonder if someone has some insight into my problem - recently I noticed my system becoming very noisy at certain points during games, and after countless reinstallations of Windows and even a power-supply swap-out, I found the source of the problem - it's the Hawk. Now here's the strange bit - the noise that I'm hearing isn't the sound of the fan, it's a buzzing kind of sound (maybe coil whine? It sounds very similar to a "processor activity" noise, if that makes sense), and it only occurs when the fan speed is between about 55%-70% of the maximum - above 70%, the noise disappears entirely. Has anyone encountered a similar issue, or figured out what causes it?
Thanks!

I haven't put the video card in another machine, but I'm absolutely certain that it does come from the video card - I tested by adjusting the fan speed in afterburner, as soon as it reaches 55% the noise kicks in, and as soon as I push the fan speed up past 68%, the noise stops. I've had the card just over a year now, and this problem only began in the last month and a half or so.

  • 560GTX TI HAWK fan speed?

    So I just got a new 560GTX TI HAWK (Bios 70.24.11.00.00) not overclocked, and the bios switch on performance.
    I was looking around in Afterburner and I noticed that when the fan speed is at 85% it runs at the full 4500rpm same as if it was at %100, so is the max the fans can go up to 85% or is there something wrong with my card?

     I just checked mine and about the same, 4560 RPM and no difference between 85-100%. It appears then that max fan speed RPM is when it hits 85%.

  • GTX 560 TI HAWK 82-84'c at 100% fan speed

    Hello
    I've noticed my hawk becoming VERY loud while playing games, Final Fantasy XIV and Deus EX: Human Revolution to name a couple. I downloaded Afterburner to see what the temperatures were and I'm astounded to see my card at 82'c at near 100% fan speed. I have the fan profile on performance mode and I have a well ventilated Cooler Master Storm Sniper with 3 200mm fans at the top, front, and side and one 120mm fan at the rear. My ambient room temperature is about 24'c so it's not my room temp.
    Here's a screenshot while FF14 is running.
    Touching the side support brace bar is hot to the touch.
    EVERYTHING is at the default clock speed/voltage.
    I think the cooler or something with the card is defective!
    Should I set up a RMA ASAP?
    If I should:
    How long is the RMA process?
    Does MSI offer an advance RMA service similar to EVGA?

    If you don't cause any physical damage to the card there should be no problem.
     Svet, is that what you use to clean it, Jim Beam whiskey and a cross peen hammer to scrape the gooey stuff off? You should be using Everclear 190 proof instead, 151 proof at the very least.
     Maybe I should check mine just to be sure. I took a look at my 465 last week and found the HSF mounting screws were loose.

    At final cleaning stage for old TIM [1st used the toilet paper, a special one, its doing excellent job for the task and its tenderly]
    then used this[dunno how they are called in English]:
    and then since the heatisnk surface and chip start shinning with light of clean and no any sign of TIm left,
    i used a drop of  Jim Beam whiskey over the
    then clean both surfaces again, then start cleaning them again with the same, but with dry one.

    What are those arrows? is that where i get to unscrew the entire cooling pipes away from the graphic board?
    Just to check with you the pipes and fans are meant to be removed and installed back - right? I meant they are not glued or riveted in - correct?
    The arrows shows the 4 for screws which you have to unscrew 1st.
    Yes, they hold the entire heatsink+fans to the VGA's PCB

    They are not riveted, only the screws hold them.
    There is TIM which works like a glue, which also holds the heatink to the GPU chip surface.
    Once you unscrew all 4 screws, then you need to take off the entire heatsink,
    don't use force, don't push it directly in up direction, start with small slides the entire heatsink as it makes contact with GPU's chip surface where the TIM is installed and works as glue, so start slide little by little, not too much and not too sharply cause the heatsink can hit and broke some of the PCB capacitors.
    Just use little and small slides until you feel that heatsink is now disconnected from the TIM/GPU surface, then take it off carefully.
    You have to disconnect FAN cable from PCB as well.

  • 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.

  • Fan speed?

    Let me start by saying that I have no problem with temps or CPU speed management - both are well within normal limits. However, over the past few days ( since kernel V 3.2.7 started IIRC) my fans don't seem to be throttling down as normal, and whilst there is some throttling taking place, the fans in my system are still running faster and noisier than before.
    Fan blades are clean, and the same effect isn't noticeable if I boot Windows. I'm basing this entirely on my own perception, but the fans seem to be spinning faster even when idle recently. I'll reiterate, if I boot Windows they are noticeably quieter, which means it's not a hardware issue.
    I switched to the ck kernel a few days ago, but this effect has appeared since then, not coinciding with the change. 3 kernel updates since and I can't be certain which update first exhibited this behaviour.
    At complete idle the fans eventually settle down, but any kind of load (even playing an mp3) will start it up and it takes a while to settle again, even though the cores remain throttled at 800 Mhz. Does anyone have any idea what may cause this?
    For info: Phenom II 965 BE O/C @ 3.6Ghz, Gigabyte M720-US3 MB, MSI Radeon HD4670 1Gb gfx card. I'm pretty sure the noisy fan is one of the MB controlled fans (probably the system fan rather than the CPU fan). Has anyone else noticed unpredictable (or rather undesirable) fan speed behaviour with recent kernels?

    Hi. Did you manage to find out what the problem was?
    I'm experiencing exactly the same one. In my case, everything started when I bought a new laptop, with faster CPU, etc. I installed, of course, the latest linux version and kernel (3.0), tried different distributions: aptosid, arch, mint, fedora, and in all of them the fans were noisier than when I run Windows on the same laptop. Symptoms are exactly as you describe. For weeks, I've been convinced that there was some issue with the Intel HD graphics card, the core i5 CPU, or even the Sandy Bridge chipset on my new laptop. But then, as a last try, I downgraded to a 2.6 kernel and, lo and behold!, now the fan runs much quieter; as quiet as in my old laptop (with kernel 2.6 as well). So, it definitely is a 3.0 kernel issue (related, or not, with the Sandy Bridge). But I haven't found any information whatsoever when googling the problem. I guess people in general don't care too much about fan noises? But it bothers me a lot, because I usually work under totally silent conditions, and then the fan is quite audible.

  • Tweak the balance between fan speed and CPU temperature / Dell M6400?

    Hi all,
    I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that

    When I start the laptop, its CPU fan stays at its minimal speed only for 1 or 2 minutes, then increases its rotation speed to a second level. It reaches it maximal speed only under heavy load, when the CPU reaches >80-95°C. I would rather let the CPU run a bit hotter before the fan starts to blow: let's say the fan could enter its intermediary speed between 70°C and 85°C instead of 55-80°C, and blow at is its maximum speed beyond that.
    I checked the Fan Speed Control wiki page, but lm-sensors is not able to show me the status of the fans. Any idea ?
    Aurel.
    PS: the temperature of the GPU is not reported by sensors, and nvidia-settings reports around 60°C. Its dedicated fan is very quiet.

    Hi aurelieng,
    I'm in the same situation from at least 1 month ( INTEL CORE 2 EXTREME X9100, 3.06GHz with 8GB ram, one solid state disk 128 GB, and one sata disk 500GB)
    My dell M6400 has dual boot: ubuntu and windows7. The fan works a lot and continuosly in both environment and this is the reason because I have doubt that the origin of the problem is in hardware problem?

  • [Solved] Asus L1366 mobo, cpu fan speed control

    Hi, everyone,
    I finally have this new core i7 system, to replace my old AMD athlonx2.  I have one question about the CPU fan speed control.
    I remember that in my old system, the cpu fan speed control works out of box, no configuration is needed.
    But when I install arch 64 on this new i7 system, the cpu fan is running at its maximum speed constantly while the CPU temperature is modestly low. I know there is a wiki teaching how to do it.
    However, I am just curious why it doens't work out of box any more? Does CPU fan control work for you guys out of box normally? especially the new Core i7 cpu users?
    Please let me know, really appreciated it.
    Thanks a lot.
    Update: the issue is solved, see my last post, the solution is blacklisting: asus_atk0110, instead use w83667hg.
    Cheers.

    First off, it would be useful to know what the sensors-detect script actually reports.
    Okay. How fan control works on Linux: First, navigate to /sys/class/hwmon
    Each of these folders, i.e. hwmon0, stands for a sensors monitor / fan controller on your mainboard that may control one or several fans. Inside hwmonN, there should be a subfolder called device, which contains several interfaces if your BIOS allows software-side fan control. You can read them with cat and write to them with echo.
    Examples:
    pwm1_enable shows if OS-level fan control is enabled (1) or disabled and in BIOS control (0). Changing fan speed won't work if this is disabled. (i.e. cat /sys/class/hwmon0/device/pwm1_enable reports 0 -> disabled; you could enable it with echo 1 > /sys/class/hwmon0/device/pwm1_enable).
    pwm1 allows to change fan speed. The values range from 0 (fan off) to 255 (full speed, 12V).
    fan1_input shows the current RPM if a fan is connected. You can only read from this interface. Its useful to check all of these in the each of the hwmon folders to find out if there is actually a fan connected to the fan controller (they often have more ports than mainboard manufacturers use).
    There might be a fan1_div, this is somehow related to how the kernel reads the RPM, I don't know how it works.
    temp1_input interfaces can appeare too, if some of the chips have temperature sensors located somewhere. I *think* lm_sensors places the core temperatures it reads from CPU (the coretemp-isa-000X thingies) in one of the hwmon-folders too.
    There might be interfaces for different fans in the same hwmon folder, i.e. pwm2_enable, pwm2, fan2_input, etc., all interfaces with the same index belong to the same physical fan connector, and all in the same hwmonN are managed by the same IC on your mainboard.
    Warning: These interfaces, if they work, control the fans directly without any kind of security measure. If you shut some essential fan down, it will stay off until you reboot your CPU shuts down.
    (If you see something likein0_alarm, in0_input, in0_max, etc. it's a voltage monitoring chip.)
    If one of those interfaces can do something, OS-level fan control does work, if none of those folders contain a working pwm interface, fan control seems to be unavailable.
    Sometimes there is an option in the BIOS to enable it, and for some BIOSs software-side fan control only works if dynamic fan control is disabled in the BIOS and fan speed is set to a static value - or vice versa.
    I don't know what you are using to control fan speed, there are many applications that use these interfaces, i.e. GNOME or KDE power managers, so I'm not sure what is happening:
    IF: Windows 7 enables OS-level fan control and sets it the RPM to those you observed and you have nothing that provides fan control in Arch and so fan control stays at BIOS-level, which might also read out a different sensor / the same sensor differently or it might be more conservative in setting fan speeds altogether;
    OR: You have something that provides fan control installed in Arch and it reads out a the wrong value supplied by lm_sensors and thus sets a higher fan speed.
    Anyway, possible solutions I can think of:
    Find out if you have some kind of fan control software and what it does. For example, I use the fancontrol daemon, I can't help you if you use something else.
    The wiki mentions how to assign a fan speed to a certain temperature sensors. You might assign it to a different one. For example, there are no sensor chips on the mainboard of my EEE (no temp1 etc.) so I assigned the fan speed to the temperature reported by the BIOS via ACPI (those are in /sys/class/thermal, also no "device" subfolder on EEEs):
    FCTEMPS=/sys/class/hwmon/hwmon0/pwm1=/sys/class/thermal/thermal_zone0/temp
    You could also change the MINTEMP/MAXTEMP values to one higher than those you actually want to compensate for the effect of lm_sensors reporting temperatures that are too high.
    It is currently not possible for a mortal user to change the coretemps lm_sensors reads, see this post, last paragraph.
    There is a configuration file, /etc/sensors3.conf, you can change sensor names and adjust offsets here, but only for the monitoring chips and their sensors that are on the mainboard.

  • Macbook Air Mid 2012 Fan speed not adjusting

    Hi,
    I've a serious problem with my Macbook Air Mid 2012. The fan speed of the system is fixed to maximum of 2000rpm and is not
    adjusting with increasing temperature. An SMC reset has not fixed the problem. At the moment I've to use iStat to increase the fan speed,
    but otherwise the Air is crashing at about 78C. Does anybody has a similar problem?
    Kind regards

    Is the problem your fan is too noisy when it is not under load?
    If your fan is running too fast you can try reseting SMC. 
    http://support.apple.com/kb/HT3964
    You can also try disabling or uninstalling SMCFanControl and then resetting SMC.
    SMCFanControl should not be necessary for the normal operation of your Mac.
    P.S.  Your English is excellent.

  • Fan speed and CPU temp

    Hi There,
    I have MBA 13'' Mid 2011.
    I'm little bit concerened about Temp of my CPU which is 96°C, and Fan speed is around 6500rpm.
    I can hear my fan all the time.
    It was not like this always and i'm kind of sure that something is causing this.
    I worked before with lots of apps open (itunes, photoshop, text editor, chrom, mail, parallels..) and fan and temp was not this high.
    Is there way to find out what is causing this high usage?
    Thanks in advanced

    First execute a SMC reset:
    http://support.apple.com/kb/HT3964
    If no change, install istat menus.
    http://bjango.com/mac/istatmenus/
    Open Activity Monitor to ALL PROCESSES and CPU.  Make certain that CPU displays values from high to low.
    Post images of both istat menus and Activity Monitor whe the MBA has heated up.
    Ciao.

  • CPU heats up on file copy/backup and fan speed does not increase

    Hi Friends,
    I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.
    Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.
    I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:
    [user@domain]$ sensors
    acpitz-virtual-0
    Adapter: Virtual device
    temp1: +60.0°C (crit = +100.0°C)
    temp2: +59.0°C (crit = +100.0°C)
    temp3: +66.0°C (crit = +100.0°C)
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0: +58.0°C (high = +105.0°C, crit = +105.0°C)
    Core 1: +58.0°C (high = +105.0°C, crit = +105.0°C)
    Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.
    Here is the main problem:
    1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.
    2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

  • My MBP temperature and fan speed

    Hi,
    My problem is that my MBP seems to be getting rather hot (the F panel at the top, and underneath in particular).
    I used to notice when I used skype video that the fans spun a little faster and it seemed to keep my MBP at reasonable temperatures. But recently its getting very hot (almost untouchable) and the fans aren't spinning faster to offput the higher temperatures.
    I installed smcFanControl2 and it showed my fans running at 1000 rpm while my CPU temperature was about 62 degrees Celsius. I've looked around the forums here and most people seem to be reporting a normal idle speed of about 2000 rpm, so thats the first thing that struck me as odd, as I'm not even using any particularly CPU intensive apps. I used Activity Monitor to check.
    I then used smcFanControl2 to up my fan speed to 4000, and it ducked underneath 50 degrees celsius, so I reduced the fan speed back to 2060 (couldn't select exactly 2000) and now its running at about 53 degrees (I'm running system profiler, console, skim, textedit, itunes, mail, and finder right now). This seems to be a much more normal temperature, and I can barely even hear the fans.
    *Now my question:*(thanks for sticking with me so far): Shouldn't my MBP automatically have upped the fan speeds to keep my CPU temperature at a reasonable 50 degrees or so? Or is the cutoff point higher and I've just never noticed before? Also, is there a program (like smcFanControl2) perhaps that I can use to set a particular temperature I want to keep my MBP at and it will automatically set the fan speed to keep it at that temp?
    NB, I recently swapped my 1 GB of Apple memory for 2 GB of Crucial memory. I'm assuming this might have bumped the temperatures up a little bit but I definitely found my MBP was warmer than usual even before the upgrade.
    Thanks for any replies!

    sternkanz,
    In general, the upper operating limit for all Macbook Pros is in the 80-90 C range. In other words, the cut-off point is higher than you think, and you just haven't noticed it. The EFI firmware and PMU is designed to managed the fans such that 80-85 C is about as hot as the CPU gets, but of course, they (the fans) ramp up a bit earlier and slightly higher temps are not just possible, but common.
    Adding the additional memory may be a contributing factor, but not by much. Certainly, having a second DIMM in place moves the heat being produced by the RAM (considerable, BTW) closer to the bottom of the Macbook Pro's case, and therefore adds to the heat you'll feel underneath. And, just having more RAM will marginally increase the amount of power your Macbook Pro uses; more power equals more heat.
    In the end, this is all normal, and I don't see that you have anything to worry about.

  • Temperature and Fan speed? screen freeze

    I Have 2011 MacBook Pro 13inch . I was having the screen freeze issue from a hot graphics card it cpu that so many others have with this year macbook. After a night of playing videos (not realizing it was in loop) connected to my hd tv using thunderbolt. After the first one it happened a few more time after playing any video for a few minutes. Screen freeze with little pixelated boxes, yellow or blue. After some research I reset SMC and seems sit of fixed it. I am not running SMC FAN AND Temperature Monitor apps and my fans run about 2000 all the time. When I get hit it speeds up but not to much, seems on point. Except when I play hd videos the system get gets to 75-80c . I still have not had the freeze but that's because I have temperature monitor to launch SMC fan set at max fan speed when it get a to 80 d
    Degrees C.  I'm wondering if anyone knows the safe temp the 2011 MacBook Pro should be running at When playing hd video. I know it gets hotter when playing hd video by without SMC it seems my fans don't kick on to max speed untill the MacBook reached about 85-90c. Once the fans max it cools it right away. I know the fans are working cause I hear them but should the fans kick on faster before it gets to that hot if a temp. And is it safe to play hd movies of its running at about 80-85c?
    Thank you for any information you might have on safe and average temp and fan speeds. If anyone has a macbook pro please let me know when your playing hd video for about a half hour or more how hot your cpu is showing.

    Macs have established a reputation for being inferior game machines.  PC's dominate that area and if that is a high priority, I always recommend a PC.

    I doubt that you almost' fried' the logic board, but you may have approached thermal shutdown.
    I also have a 2011 MBP and have run applications that are CPU/GPU intensive with no issues (the MBP certainly does heat up and gets very warm).  I have never felt the need for a third party fan control. 
    If you wish to run games a lot, a cooling pad and a cool environment would help the situation.
    Ciao.

  • How do you change the fan speed (rpm)

    On a mac, how do you change the fan speed to 7200 or something?

    As was mentioned, installing smcFanControl will do this:
    http://81.169.182.62/~eidac/software/page5/page5.html
    However, as others have indicated, you should determine what the issue is.  For starters, is your machine actually running hot?  Have you run something to let you know what the actual temperatures are?  Setting the fan at max speed will make your system noisy, will reduce the fan life, and significantly reduce your battery charge.

  • Fan Speed off the Charts

    I'm running a 15.4" 2.16 core 2 duo with 10.6.6.
    Last week my fan(s) decided to start being really loud. Right now my CPU is 92% idle and I have 1.14 gb free of my 2gb of ram (according to activity monitor), but my fans are going an average of 6000rpm (according to SMC fan control). The computer is at 43 degrees celsius.
    I have nothing set to turn up my fan speed. Any ideas?
    Thanks

    First thing is to see if a sensor has failed. Find your original system disk/s and use the one that is marked as bearing Apple Hardware Test. Instructions are here:
    http://support.apple.com/kb/HT1509
    Note that the fans will run high (6000 rpm max) while running AHT. That's normal. I set my MBP up on little spacers to allow air underneath during the test.
    Most people don't have the translator for any error codes that might appear, but if you post the errors here, some may look familiar enough that one of us can take an educated guess. Errors with "SNS" embedded in the code are generally sensor codes.
    There are several things you can do to investigate heat/fan issues:
    1) See if any background processes are eating up CPU cycles. Quit all running user applications so the computer is at normal idle. Find Activity Monitor and launch it. IMPORTANT: change the "Show" pulldown at the top of the AM window from its default of "My Processes" to "All Processes." Some of the real culprits may not show if AM only checks user processes. There is a column for "%CPU." Click that column header to sort by CPU usage.
    If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated.
    2) Make certain your physical arrangement of the computer and your usage patterns are not contributing to overheating. Apple recommends against using the MBP on your lap or any surface that contacts the case bottom. The case bottom is part of the heat dissipation system and needs air. If you need to use the computer in your lap, make a simple lap board from scrap plywood. The height of the rubber feet is usually enough to let the air move but, if you are playing graphics-intensive games, you may want to insert some 1/2-inch (13mm) spacers, or get a powered chill pad to help move heat away.
    The main exhaust vent is under the display hinge on the back panel of the case. It must not be obstructed.
    Here is an Apple article on temps but it does not list critical temps for any model:
    http://support.apple.com/kb/HT1778
    For the silver-key MBPs, the safety shutdown to prevent heat damage is aout 100C/212F. Your 43C is well within the normal range and should no be making the fans go all out unless SMC Fan Control is set to do so.

  • MSI H81M-P33 Cpu Fan Speed Problem! Urgent

    Hi. Bought a H81M-P33 board and got a problem.
    I can´t increase my CPU fan Speed to maxium RPM . Tried to use Command Center and Board Bios without any sucess.
    This leads to my cpu (i5 4670) getting hot with stock cooler. When I´m encoding a video it reaches 85º. The best solution I had was to connect CPU Fan to Chassis Fan slot on the motherboard and it increased speed, but still it doesn´t increase past a certain value.
    What can I do to solve this problem? Tried everything without any luck. The board doesn´t handle CPU fan speed + temperatura increase well. Is not normal to have a CPU stock volts getting hot.
    Thanks

    I know that for sure XFM. The thing is that the board isn´t increasing CPU fan speed as it should. Ofc a better cooler would do the job, but even with stock cooler it can be cooler. The problem is that the fan is always in slow mode :|
