Control Fan Speeds With SpeedFan [Tutorial]

Control Fan Speeds With SpeedFan [Tutorial]


What is SpeedFan? SpeedFan is freeware. SpeedFan
monitors voltages, fan speeds, and temperatures. SpeedFan can dynamically adjust fan speeds
based on changing computer temperatures. SpeedFan runs on Windows 9x, ME, NT, 2000, 2003, XP,
Vista, and 7. SpeedFan also has 64-bit support. Let’s download and install SpeedFan. Open
a web browser like “Internet Explorer”. In the address bar, enter “almico.com/speedfan.php”,
and press enter. Click on the “Download” tab. Under the “Download” section, click
the “SpeedFan 4.45” link. On the “Download Information Bar”, click the “Run” button.
This will download the file, and then automatically start the installer. On the “SpeedFan Setup:
License Agreement” window, read the license agreement, and then click the “I Agree”
button. On the “Components” screen, leave all options selected, and click the “Next”
button. On the “Install directory” screen, click the “Install” button. Once the installation
finishes, click the “Close” button. You can start SpeedFan in one of two ways. Option
one. Double-click the “SpeedFan” icon on the desktop. Option two. Click the Windows
“Start” button, “All Programs”, “SpeedFan”, and then select the “SpeedFan” option.
On the “Hint” window, click to select “do not show again”, and click the “Close”
button. By default SpeedFan uses Celsius and not Fahrenheit like we use in the United States.
Let’s change this to Fahrenheit before we start looking at setting up SpeedFan. On the
“Readings” tab, click the “Configure” button. On the “Configure” window that
opens, click the “Options” tab. Click the radio button to select “Fahrenheit”,
and then click the “OK” button. We can now see that all temperatures are in Fahrenheit.
Let’s review the ‘Reading” tab. In the top of the screen, you will have the output
window that will show a log of the items scanned and found. Below this you will see bar graphs
representing each core in the CPU. There are three graphs showing because I have three
cores in the AMD Phenom 2 x3 720 processor running in this computer. To the right, you
have a two buttons. The “Minimize” button will minimize SpeedFan to the system tray,
but will remain running. By clicking this button we can see that the icon for SpeedFan
in the taskbar will disappear when we click on “Minimize”. You can open SpeedFan back
up by clicking the SpeedFan icon in the system tray. By default Windows only shows a small
portion of the items running in the system tray. If you don’t see the SpeedFan icon,
then click the “Show Hidden Icons” button. Then double-click on the SpeedFan icon, which
will be showing the temperature for Temp1. If you want this to show in the system tray
at all times, you can click on the “Customize..” button. Scroll down and select the “SpeedFan”
option. Change the drop down to select “Show icon and notifications”. Then click the
“OK” button. We can now see SpeedFan in the system tray. To open Speedfan back up,
double-click on the Speedfan icon in the system tray. Below the “Minimize” button we have
the “Configure” button, that has all of the settings for the application. We will
go over this more later. In the middle of the screen, we have all of the fan speeds
in the left pane, and the temperatures in the right pane. Below the speed and temperature
information we have the controllable fans in the system listed. This will typically
be the fan connections on the motherboard. My motherboard supports 6 fans, but i am only
running 3. By default the speed for all fans is set to 100%. At the bottom of the screen,
we have information on the voltages of various components. The “Clock” tab is used to
overclock you processor. There are much better programs for overclocking so I would recommend
avoiding this option with SpeedFan. The “Exotics” tab is rather interesting. If you don’t
see anything showing, click the “Show the magic” button. You will get a nice view
of all the different settings being monitored. The “S.M.A.R.T.” tab, allows you to view
the SMART information of your disk drives. Selecting any drive will show information
like the error rate spin up time seek error, and so on. The “Charts” tab will allow
you to graph “temperatures”, “fan speeds”, and “voltages”. Clicking any of the options
will start to graph them with their own unique color. This is really useful to fine tune
the fan speed control to the exact temperature patterns of your system. Now that we have
reviewed the available information in SpeedFan, let’s get into using it to control the speed
of our fans. Back on the “Readings” tab, you can adjust the speed of your fans just
by reducing the settings manually here. If you use a static setting for the fans here,
you will want to set this to graph the temperatures on the “Charts” tab, then run a game or
other application that will stress your system. After running it for at least 15 minutes,
take a look at your readings. If any of the temperatures get higher than you would like,
then adjust the fan speed higher. In addition to being able to manually set a static speed,
you can also set the fans to increase and decrease in speed based on varying temperature
readings. Let’s click on the “Configure” button. The “Configure” window will open.
You can select which “Temperatures”, “Fans”,and “Voltages” to monitor with the first three
tabs. The “Options” tab has settings you might want to adjust to your liking. If you
have trouble with anything you might want to come to the “Log” tab, click to select
this “Enabled” option, and then see if you get additional information on your problem.
The only thing we are going to go into detail about is the “Fan Control” tab. Click
to select “Advanced fan control”. Here we setup thresholds for temperature and fan
speed. Typically you will want to create a separate rule for each fan in your system.
This system has 3 fans as we saw before. We will create a rule for each of the three fans.
For this system “Temp2” is the ambient temperature inside the computer case. Click
the “Add” button. I’ll create three controllers. Enter a name for the rule. We’ll
call them “Fan4”, “Fan5”, and “Fan6”. After creating the 3 controllers. We’ll
select “Fan4”. We now get additional settings for each controller. Click to select “Controlled
speed”. Click the drop down to show the available fans, and select the first fan to
control. We’ll select the fan for “Speed04”. Now we need to tell this controller for fan
4 what speed it needs to run at for each temperature setting. Under “Temperatures”, click the
“Add” button. The “Select temperature” window will open. Select the temperature to
use to control the fan. “Temp2” is the temperature of my computer chassis. We’ll
select “Temp2”, and click the “OK” button. We’ll go and setup the other two
fan controllers the same way. If you click on the entry under temperatures, you will
see a graph with the temperature and the corresponding fan speeds. You can adjust these by clicking
on
the graph. Once complete we’ll click the “OK” button. Before the automatic control
settings take control, you need to click to select “Automatic fan speed”. We can see
that as soon as we click this button the fan speeds change from 100%. Ok, so at this point
we should have SpeedFan installed and configured correctly. As it is now, we would have to
start SpeedFan each time we restart Windows. Here we will create a shortcut for SpeedFan
and place it in the Windows
Startup directory. Click the Windows “Start” button, “All Programs”, and the right-click
on the “Startup” folder and select “Open All Users”. A Windows explorer window will
open. Any shortcuts placed in this folder will run after the Windows desktop loads.
Right-click and select “New”, then “Shortcut”. On the “Create Shortcut” window that opens,
click the “Browse…” button. Unless you changed the install location, browse to c:program
filesspeedfan and then select “Speedfan.exe”. Then click the “OK” button. Click the
“Next” button. Change the name to just “SpeedFan”, and click the “Finish”
button. There is now a new shortcut in the Startup folder for SpeedFan. Now every time
a user logs into the system it will start SpeedFan automatically. The only other thing
we need to change is to set SpeedFan to start Minimized so we don’t have to click the
“Minimize” button every time. Click the “Configure” button. On the “Option”
menu, click to select “Start Minimized”, and click the “OK” button. We can now
see
that if we close out SpeedFan and then click this shortcut again, it will start and then
automatically minimize to the system tray. You should have a good understanding of SpeedFan
and it’s basic features. You should also have your system setup to be properly cooled,
while being quieter than before.
