Finally ready to fix my cpu fan noise - can someone PM?

So I have a 17" rev a imac (1.8 ghz) - now that my 3 year Apple Care plan is up (a new power supply, 2 new logic boards, and a new hard drive later) - I am ready to do anything to fix the model airplane fan noise/whine coming from the CPU fan. I know when the issue has at the forefront a couple of years ago, there was a housing modification that seemed to work for a lot of people, but I haven't been able to find it again. Could someone PM me with info about it if you know of it?
Thanks!

  • Satellite L670 cpu fan noise

    As I sit in front of my new L670 laptop, from the left end of the keyboard comes a frequent whirring up and down sound that i'm pretty sure is the CPU fan
    (not the HD).
    How much of this is too much? I find it disturbing.There's no sound like it from my 1 year old Toshiba. The temperature of the room is a constant 20degrees, so it isn't overheating.
    And it does it even when sitting idle with only the Windows7 screen up ie no software activity going on at all.
    I'm worried this is a defective computer. It's 2 days old (to me) - purchased brand new. Still could take it back.
    Grateful for any thoughts.

    I also have a Satellite L670 and have the same fan problem.
    I bought this laptop 1 month ago and the problem was there from the begining. I have already set all the possible parameters to lower power consumption, and I set the CPUs to run between 1% and 50% of their maximum frequency. The problem is still the same. The problem does not come from the user nor the settings, but from the laptop itself.
    IMO the problem is that this laptop refuses to set fan speed at e.g. 25%, 50%, or 75% of its maximum speed, depending on the temperature. The fan is either off (silent) or runs at full speed (too noisy). That is NOT a normal nor optimal behavior and Toshiba should fix it (BIOS update?).
    I tried speedfan but it could not change the fan speed.
    My other laptop, a cheap brand machine which I have been using almost everyday for over 5 years, is much quieter. When using a lot of CPU the fan will indeed make some noise, but that seldom happens in normal use and most of the time the fan runs at low speed and is barely noticeable.
    Any solution to this problem would be greatly appreciated!

  • Cpu fan noise

    Hello! Today I installed windows 10, and suddenly my cpu fan is running pretty loud. I also changed my video card from a sapphire amd radeon 6950 to a gigabyte amd radeon r7-240. I installed the graphics card with windows 7 and I did not have this fan noise from my cpu fan, but when I upgraded, I check the temperatures and its running at almost 80 degrees celcius without doing absolutely anything. All my drivers are up to date. what could be the problem? thank you in advance, Edgard

  • Max CPU fan that can be installed

    Newbie here......... Was wondering what the maximum power rating of the CPU Fan Header on the MSI Neo2 FIS2R is. Can I install a 90x90x25 fan rated at .32A on it.

    Well I have my little Rule of, Anything over 1/4 Amp. is better off on it's own PSU Molex Dongle (As it should be a 4 Pin connection with 1/3 of an Amp and above). I have Heard that 1/3 of an Amp is The MAX for a Boards Fan Header, But Like I said, why Chance over 1/4 if you can use the PSU for Power, and Just splice into the Wire, and Use the RPM Monitoring Pin of the CPU's 3 pin Fan Header......And you Have to Look to make sure that is the MAX Amp Rating, Because these Fans Use More Power uppon initial Startup, then their Continiuos Amp Draw...But Again this is just my Opinion, and I am Far from knowing all that much...........Sean REILLY875

  • Lenovo U450p Fan control Can someone modify?

    Hello!
    i found a thread where a guy modified the Idepad 350 Bios so that the fan noise is fixed. Can someone also do this for the 450? This would be great! Many thanks!

    to deshilachado
    Glad to see that you're fully satisfied with your laptop now.
    I didn't change temperature thresholds, only two fan speeds were modified (they are used when CPU temperature is below 55 Celsius). Now the fan rotates on almost inaudible speed while CPU temperature doesn't exceed 55 degrees.
    Of course your laptop will be a little hotter in idle than before but it's inevitable payment for silence.
    By the way, you can safely turn off the useless wmpnetwk.exe (see all details here).

  • Finally made top 10 on Leaderboard! Now can someone explain..

    I showed up as 9th yesterday (10th today) on the Leaderboard when I select for my age group, gender, "Duration" and "Ever". A time was listed as 40:39'30". What does this time reflect exactly? Is it tied to a 5k or some other default run type? I pretty much only walk and I've gone for nearly two hours once (14k).

    Duration in the Ever column is the total amount of time that you have walked/run with your Nike+ kit. Distance Ever is the total number of miles that you have covered with your Nike+.
    You were an early adopter of Nike+ so every step you have taken with Nike+ will be represented in the Ever column and put you out in front of someone much faster who started using Nike+ much later.
    The slower your pace the greater the difference between your ranking for distance and your ranking for duration.
    The 10 km & 5 km Ever are self-explanatory.

  • G72-b57cl notebook mic noise from CPU fan

    g72-b57cl notebook mic noise from CPU fan
    At first I bought this laptop, mic setting was disabled. I enabled this, and then I can't talk through the mic because of noice from CPU fan. how can I solve this problem?

    See, I'm not entirely sure it's the fan.  I can just hear it more easily the closer I get to the fan, which leads me to believe it's somewhere around there.  As in, not the HDD on the other side of the computer, though I suppose it could feasibly be it.  I also think I could have described the noise a bit better.  It seems to sound like the CPU when it's under strain, but...not the same, I can't quite explain it.  The computer will heat up and spin the fan independently of this.  If it is the CPU or GPU, then I don't see what's generating this extra load separate from the nvidia-utils, which I already had earlier.

  • Grinding fan noise on both my g4 1117dx

    I bought two g4 1117DX laptops in August.
    First one and now both have fans that make a horrible rattling noise.  I updated bios, but no change.
    I have blown out the vents, no improvement.
    Let's be clear, this is not the noise of a normal fan. They make one hell of a clacking noise. For instance Skyping is impossible now.
    These laptops are virtually new and in pristine condition.
    I suspect that the fans will need to be replaced. They are under warranty, but I don't want to lose the use of them by sending them away.
    Is there any alternative to replacing the fans?
    What fan should I use to replace them?
    Given that both the OEM fans are faulty is there an alternate supplier?
    Will HP send me two new fans for free?
    Where are instructions on fan replacement?
    Thanks

  • Smart CPU Fan Working?

    I have Smart CPU Fan enabled in bios.
    Target 40C
    Tolerance 5
    default bios.. seems to be fine other than this one fairly minor issue.
    Anyways, the Smart CPU Fan control seems to work only half the time. I'm using a Zalman CNPS7000CU heatsink w/o the fan controller. The fan is directly connected into the CPU fan header to the "left" of the CPU socket. Upon booting, it'll spin at max speed; approx. 2 minutes later (on a good day ), the fan speed will start to slow from 2700RPM to 1300RPM. This only seems to happen about 35% of the time. The controller also seems a bit sluggish. Sometimes it won't power up the fan speed even if the temperature goes up to 45-50C.
    I'm sorry if this problem has already been addressed, but I couldn't find any information about it in these forums.
    So.. is there a solution? A new bios w/ a fix? Do I have it configured correctly? Please help  

    I don't like anything that tells the CPU fan it can shut down.  

  • CPU Fan Has Failed! PC will automatically power down

     CPU Fan Has Failed! PC will automatically power down
    HP Pavilion Slimline s3714uk Desktop PC, running windows 7.
    I started to get CPU fan failure message  and the PC would not boot, I opened up the case and the CPU fan seems to be connected and working.
    Error message is “"ERROR: CPU Fan Has Failed! PC will automatically power down in a few seconds. Service the PC immediately to prevent damage to the PC."
    I have found the following advice:

    However the bios version I have does not have the option to switch off the fan monitor. How can I fix this issue please: many thanks

    Hi Susielee.  what was the heat sink and cpu fan that the tech installed in your HP computer?  I got a used HP s5120y computer from a longtime friend that is missing a processor fan but the heatsink is there.
    update 2/14: never mind, my old friend forgot to give me the CPU fan, which he did a few days ago.  I used a flashlight to check if the fan is working and it is but I'm still getting "CPU fan has failed" error everytime I power on the computer but the cpu fan spins okay at normal speed.  replacing the cmos battery did nothing to solve the problem.
    I will either replace the whole heatsink & fan before I will consider replacing the motherboard, which seem to have a least 1 ruptured capacitor on the board - that indicates some parts of the motherboard are starting to fail, like the fan sensors.  The HP part number of the board printed on a sticker in the HP slimline S5120Y computer is "513426-001"
    So in short replace the heatsink & fan assembly first.  Then replace either the power supply and chassis fans.  If those don't fix the CPU fan failed message at bootup, replace the whole motherboard.

  • Need help choosing a good CPU Fan.

    I'm running an AMD Athlon XP 3200+ on my motherboard.  I would appreciate any suggestions on a good quality CPU fan. Can't establish a good overclock without good stability, which comes from how well you keep your system cool.  Nevermind what I just said, I'm talking out of my *censored*. Anyway, I could really use some recomendations.

    Hehe,
    i use a vantec tornado....
    http://www.newegg.com/app/viewProductDesc.asp?description=11-999-612&depa=0
    i will give you plenty of warning, she is loud....however she blows some air!!!84.1cfm's to be exact  but yes there is a comprise when using this thing...
    if your heatsink will accept a 90mm fan, then i would suggest giving it a try if your going for a record oc or something to the effect b/c the 90mm moves some 10cfm's more i believe....
    unless your going to watercool, get one of these... mated with the proper heatsink youll be just fine... my tornado keeps the thing at 33C with a full load... you wont be disappointed with the cooling, !!!!!

  • Hp dv3t 2000 overeheating/fan noise/cpu spikes

    hi, i own a hp dv3t 2000 which is just about six months old. Since around a month ago I have been experiencing increasing fan noise and cpu spikes (100% cpu usage when really i'm not doing much at all)
    i looked into this issue online and learned that it may be a airflow problem, so i wanted to take a look inside.
    here's my frustration - i cannot take out the case because the screws are put in really tight and stripped, making it impossible to unscrew them. after 2 hours of intensive labor trying to unscrew my **bleep** laptop, i am so frustrated and angry that hp cannot bother to use a decent set of screws in their products.
    i wonder if hp will take it in and have it fixed with the one year warranty on the product.

  • Santa Rosa Macbook fan noise fix, sort of

    I don't know how many of you guys noticed this, but when I got the new Santa Rosa MB it was definitely louder than my previous C2D Macbook. Even when idle doing nothing.
    I found out that the lowest rpm on the new Santa Rosa goes at 1800, which in a quiet room at night is way to loud personally.
    In order to fix it just download fan control 1.2 and then put the lowest RPM setting to 1000. For me that instantly made the MB super quiet again.
    Hope that helps to those that wish more silence out of the Santa Rosa books.

    I made an appointment at the Apple Store I got it from (4 days after I purchased). I told them about the weird clicking noise and they took it to the back (store was pretty loud) and came back in a few minutes and offered to exchange it since I was within my 14 days. The new one is way quieter and only makes fan noise with intensive processes (as expected). Doing some research after the fact, I believe my issue was the ticking/clicking one described here: http://www.appledefects.com/wiki/index.php?title=MacBook#.22Mooing.22fan_noise.2C_Ticking.2FClicking_Fannoise Overall, they handled it pretty well (I was prepared to field an inquisition about this manufacturing flaw, luckily I didn't have to and they recognized the problem pretty quickly), and I'm finally enjoying my new MacBook.

  • CPU Fan Making Tons of Noise

    I just got my iMac 24" back from a repair for the LCD screen, and when I bring it home I hear the CPU fan beginning to make a ton of noise when I only have one application (Safari) open. Even after closing it and having nothing open, the fans going nuts. I have an application to tell me how fast the fans in the computer are going, and it's running at 3600 rpm, when normally it only peaks at 1700 when having around 10 applications open at once. So, I took it back to the Apple store and the next day they said they "fixed it." Apparently not, because I just went all the way back there, came all the way back home, and the fan goes right back to 3600 rpm when having nothing open.
    Note: I've NEVER had the fan go above 1700 rpm before taking the computer in for an LCD panel replacement. It's Apple's fault for the fan being broken apparently, and they can't even fix it.
    What do I do now? I just bought my computer in May, can I get a refund for it now? I'm not going back and forth to the Apple store every time they say they "fix" it when they really haven't done anything. I just want my money back, or a brand new computer, and I'll be happy.

    Interest. I got my 24-inch spring 09 iMac back recently from a LCD & logic board replacement and my CPU is also "going insane". The CPU fan is now running at 3600 as soon as I open most any application and then it stays there. Didn't happen before the service. I'm concerned that the speed increase will reduce the fan life, but more than that the noise is killing me. I got this iMac to replace a noisy G5 iMac and until this recent turn I've loved it because it has been so silent. My CPU temps have remained steady around 35 - 40 degrees C so it's not due to higher than normal temps.
    I haven't had time to call Apple about it yet. But hope to do so soon.
