laptop cpu fan rpm

I downloaded SpeedFan and it reports that my CPU temperature peaks at about 73C which seems to be normal according to this chart (although the little flame icons in SpeedFan worry me). However, is a CPU fan speed of 3590 RPM normal? The CPU fan reaches this speed after I e.g. open thunderbird, tweetdeck and a youtube video in firefox. At this speed the fan spins so vigorously that I can feel a light vibration in the table above the computer, and it makes a high pitch drone/whine like an airplane taking off. Is my fan broken or is this speed much too high for a CPU fan? Here's a picture of the fan: 73 degrees is a little high if you ask me. The RPM of your fan is determined by a host of things but ~4000 is fine I tend to like slower fans that move more air because they are quieter. If the noise is bothering you buy a large fan/heatsink for $30-40 and replace it
By the look of the photo, though, you have a stock heatsink and fan assembly.

Do check the internal dimensions of your case, though, as some of these more expensive coolers can be pretty sizeable. The speed of the fan is highly subjective to the controller regulating it, the type and model of the fan itself, or the load/temperature of the CPU. From my experience, that speed is nothing out of the ordinary. What kind of system is this running in? Is it an aftermarket CPU cooler or stock? The RPM is normal I would say. Temperature is a bit high. Would be wise to maybe change the Fan for a better one. Or more importantly make sure that you have some circulation through your computer case. My computer was very unstable, although in my case it was the PSU that was getting too warm.
Anyways, it was fixed by getting a new case that allowed for some fans to be put on the front, back and side. I had one in the front and on the side blowing in. And one on the back in addition to the PSU to suck air out. Try to put some thermal grease on your processor and after that think about changing the fan. If you're going to fly it's good to have over 3500RPM at least.Browse other questions tagged fan cpu-usage or ask your own question.How to Increase the Fan Speed on a Laptop Increasing the speed of your laptop's CPU fan will help cool down the processor. Stockbyte/Stockbyte/Getty Images Small business owners have found freedom and mobility through the use of laptop computers. But for all the benefits a laptop brings to the operation of your business, it can prove to be just as detrimental if your data is lost at the hands of an overheated processor. If your laptop is running too hot, the first thing to do is make sure its vents aren’t obstructed by dust, which is the most common cause of thermal problems.
If clearing them doesn’t do the trick, you might want to try increasing the speed of the CPU fan. 1. Select "Control Panel" from the Start menu. 2. Click “Hardware and Sound,” and then “Power Options.” A new window opens. 3. Click “Change Plan Settings,” and then “Change Advanced Power Settings.” The “Power Options” dialog box opens. 4. Select the “Advanced Settings” tab. 5. Click the plus symbol associated with “Processor Power Management” to open an options submenu. 6. Select “System Cooling Policy” from the submenu. 7. Click the down arrow under “System Cooling Policy” to reveal a drop-down menu. 8. Select “Active” from the drop-down menu to increase the speed of your CPU’s cooling fan. 9. Click “Apply” and then “OK.” Tips Warning Photo Credits Stockbyte/Stockbyte/Getty Images Suggest an Article CorrectionIf your computer's running a little loud for your tastes, it's probably because your fans are running at full speed—even if they don't need to be.
Here are a few ways to manage your fan's speed so they're keeping your computer cool when they're necessary and silent when they're not. We've talked about how to quiet an especially noisy fan before, but focused on computers running too hot or not clean enough. If you've built your own computer, chances are your fan speeds aren't being regulated, and they're just running at full speed all the time. This makes for a very cool computer, but it can be annoyingly loud, especially if you don't need those fans running. There are a lot of ways to regulate those fans, many of which are completely free. Here's how to set them up. The most ideal way to control your fans is with something like previously mentioned SpeedFan (or, if you're on a Mac, previously mentioned smcFanControl). These will give you the most control over your fans, letting you choose how fast they're running at any given time. SpeedFan can even monitor your computer's temperatures and adjust the fans accordingly. And, if you head to SpeedFan's configuration, you can even tell it your desired temperature and have it adjust your fans automatically based on that.
Just be conservative, since your motherboard's temperature values aren't always accurate to the degree. The one downside with SpeedFan is that it isn't compatible with every computer out there. You can check out their Support page to see if it'll work with your machine, or just try it out yourself. If it doesn't work, you can skip to the next method and see if there are options in your BIOS instead. SpeedFan also requires that your fans be plugged into the 3- or 4-pin headers on your motherboard, not the large, 4-pin Molex connectors. If you only have Molex connectors available, you'll need to skip to method three. And lastly, it won't control all the fans in your machine—just the ones for which your motherboard supports fan control. If you want to control all your fans, you'll need to resort to method three below. Many motherboards have fan control built-in to the BIOS settings these days, though they don't always give you as much control as something like SpeedFan does. But, if your computer isn't supported by SpeedFan, this is a good plan B. Open up your motherboard's BIOS settings (usually by holding a key like Delete when you boot your computer), and search for the fan settings.
They're called all sorts of different things (for example, Asus has "Q-Fan Control", while Gigabyte has "Smart Fan Control"), but generally you should be able to find it under one of the BIOS menus. Enable this feature, and tweak any settings it gives you to your liking. Some machines may only let you set it to conservative or liberal mode, while others will let you individually set temperature thresholds like SpeedFan. It'll also offer you a choice between two regulation methods: voltage and PWM. The voltage mode adjusts the voltage of the fan, while PWM mode sends calculated voltage pulses to the fan to make it run a bit slower. For the most part, this depends on how your fans are plugged into the motherboard. Fans connected with a 4-pin connector should use PWM, while fans connected with a 3-pin connector should use voltage. Voltage is slightly less efficient, and you can't get speeds quite as low as with PWM, but PWM can be finicky sometimes too. If you find PWM is giving you problems, you can always switch to voltage.
And, if you can't connect your fans to the headers on your motherboard (that is, if you're using the large, 4-pin Molex connectors), you'll need to use method 3 below. Again, your motherboard will only support this kind of fan control for a few fans, too (usually your CPU fan and a system fan). If you want to control them all, check out method three below. While the above methods are great for automatic fan control, they aren't always available on every motherboard—and they'll usually only control one or two fans in your rig. If you want control over everything, you can install an inexpensive fan controller like one of these from Newegg. It fits in one of your computer's drive bays, and gives you a number of knobs that let you manually control the speed of each of your fans. It won't monitor temperatures for you, so you'll have to keep an eye on them with something like RealTemp or Rainmeter—but it will give you full control over every fan in your machine.
