#9 in System Utilities SpeedFan helps you stay on top of your system's vital statistics, including temperature, fan speed, and others, to ensure that things are running smoothly. Aside from basic monitoring, this program enables users to troubleshoot issues and make adjustments to various systems.Pros Clear interface: This app's interface is nicely organized into sections that you can move through using the tabs across the top of the screen. Options here include Readings, which features stats about CPU Usage, Fans, Temperatures, and more, Clocks, which lets you reset your Motherboard clocks, and SMART Data. Charts section: There is also a section that lets you create charts to visualize data recorded about various aspects of your computer. You can choose to see readouts of Temperatures, Fan Speeds, and Voltages to get a better idea of the way these values are trending over time so you can quickly identify when something is going wrong.Cons Not for beginners: Most of the information this program presents will have little meaning to inexperienced users.

There are good warnings about taking actions that could potentially harm your computer if you don't know what you're doing, so you're not likely to do any harm. But it won't do you much good either.Bottom Line SpeedFan is a nice, free utility to help you monitor various aspects of your system. It presents all data clearly, and you can find what you're looking for quickly, thanks to the conveniently tabbed interface. It's not much use if you don't have some significant knowledge about your computer's inner workings. But for power users, it's a good tool. SpeedFan monitors voltages, fan speeds, and temperatures in computers with hardware monitor chips. It can even access SMART information for hard disks that support this feature, and show hard-disk temperatures if that are supported. SpeedFan fully supports SCSI disks and can even change the FSB on some hardware (but this should be considered a bonus feature). At the lowest level, SpeedFan is a hardware monitor software that can access temperature sensors, but mainly it can control fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your PC, thus reducing noise and power consumption.

Gives blue screen consistently as SpeedFan starts to load. Four tries -- always the same. Maybe my computer is just too old... Earlier version ran ok on my machine.

Utilities & Operating Systems Add to my list More Products to ConsiderIf 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.
