How to determien which direction a case fan blows

I have the 120mm and 80mm 4 red LED Typhoon case fans. I need to know which direction the fan's airflow goes. The blades have one side curved in and the other curved out. Which way the air will flow?
Thanks.

    I could not find the arrows that was why I posted the question.



    In the center, one side has the product label. Aslo can the curvature of the blades reveal which way the air will blow?



    Thanks.

If you look on the sides of the fan there will be two arrows on one of the sides indicating the direction of the airflow. Thanks and please take a moment to rate this answer with a fixya rating. Thank you.

    Odd, usually there are arrows :c) Nonetheless, the airflow goes in the opposite direction of the curve. In other words, the curve goes down, the airflow goes up and the rotation is counterclockwise.

Rear grill computer case fan


The larger holes are for a 120mm fan. The smaller ones are for a 80mm fan. Personally I would get a 120mm fan.

You can get a good deal on a 120mm fan here:

What size case fan for HP Compaq dc7600?


What size case fan? Dunno.

1) How to measure the fan? Across the fan's shroud. (Surrounding Cage) Fan stood up, measure the Height, and Width.

2) Look at the label on the fan's center hub. Write the number down.
Now which of these CHASSIS fan numbers match?

http://www.sparepartswarehouse.com/HP-Compaq,Business-Desktop-dc7100-dc7600-dc7700,Computer,Fans.aspx

A) 3777791-001
Chassis Fan - 70mm x 70mm x 15mm.

70mm x 70mm is the height and width of the fan's shroud. (Surrounding cage) [ Chassis fan stood up ]

15mm is the Thickness of the fan shroud.

Nope, not that one.

B) 451144-001 Chassis Fan - 92mm x 25mm

Could be.

C) 455310-001 Chassis Fan - 92mm x 25mm.

Could be.

What is the best way to keep these computers running cool? They only come with 1 fan, the CPU fan. I installed a new graphics card which comes with 3 fans on it (radeon 6950) and added an 80mm fan at the...


Hello, I am the technician that you be assisting you today. My name is Norman-Wynne Damstra.

Welcome to Fixya Jeffery.

Yes you are quite correct, your upgraded computer system is giving off a large amount of heat, that graphics upgrade is quite substantial.

See these off the shelf PC's from manufactures really don't take the computer gamer's needs into account with regards to cooling. Gaming gear gives off a whole bunch of heat and this heat as you have come to find needs to be expelled quite quickly for a stable and cool gaming computer system.

Here are two possible solutions for this problem:
Option 1.) Installing cooling into the side panel is the easiest, most effective way of cooling your computer's components. I would reccomend installing at least two 120mm fans. What you do is set the one so that the fans hub would sits directly above the CPU. This fan would therefore provide freash cool air from outside the chassis to your CPU cooler.
The second fan would be installed so that the hub sits slightly below the Circuit Board (PCB) of the Graphics card. This fan would therefore provide freash cool air from outside the chassis to your Graphics card. Be sure to check that the fan, once installed over the Graphics card clears the actual graphics card once the side panel is slid closed.
You will need to measure and drill 4 holes for each fan, and then cut out the metal in the middle for air to pass through the chassis side panel. One can buy 120mm fan grills to protect anything large from touching the fan blades, it also makes the mod look smart and finished off. They are bought in crome or black finish. Check your computer store.

Now that the intake is sorted your will need to work on a suitable spot to install exhaust fans. Some-times there is enough space around the rear 80mm fan to drill and fit a 120mm fan. Again you will need to drill 4 holes and cut away the middle of the chassis for the air to pass through the chassis. You will need to check if this option is available to you. Another exhaust option is the top of the chassis for natural convection currents (hot air rising), usually install either 1 or 2 120mm fans depending on the position of the Power Supply, as some are fitted on the top and others on the bottom.
Visit your local computer store for fan mounting; kits, ideas, available fan speeds and airflow rates, purchase fans.

Option 2.) Involves the purchase of a suitable gaming computer chassis. These would be better suited to your gaming setup/needs and have lot's of fan install points. You would want to get one, if you so choose that offers 120mm or 140mm fan mounting options. Usually offering in excess of 3 mounting points. Giving your computer components freash air, thereby decreasing tempreature, increasing performance, reliability and longevity.
There are lot of diffent sizes and styles available.

I would reccomend either Cooler Master 690 series or Corsair.

Take care!

Usually the red is +12 volts DC, the black is ground, the yellow is the tach sensor, and the blue is speed control. The fan will run at full speed off the red and black. The yellow and blue are of no use unless the motherboard is designed to use them.

I have an old gateway 7023ge computer and i wanted to find out the size of my cooling fans so i can replace them. i have 2 fans one front and one rear. they are both the same size.


Computer case fans for older computers were usually standard sizes of 80 millimeter or 92mm, maybe120mm. 25.4mm = 1 inch, so an 80mm fan is about 3 inches. Measure the diameter of the fan from the tip of one fan blade to the tip of the opposite fan blade. A 92mm fan is about 3 1/2 inches in diameter and a 120mm fan is about 4 3/4"

Again, these sizes are _nominal_, so whatever your measurement is closest to is what you need. You should be able to measure the rear fan from the outside back of the computer without taking anything apart.

Replacing the fan or fans in a dell 4600 with the quietest fan I


First you need to tell us which fans are the loud ones you are talking about but normally it is the cpu fan. Any computer parts store should have various fans available for different chipsets.
This link will take you to a page to find a fan. You will probably have to get the model number off your current one to find an exact match

Case fan for pavilion 533w


well the fan sizes usually go like this.
80mm
92mm
120mm

If 80mm is too small then its got to be 92mm or 120mm but 120mm are usually reserved for the more expensive pcs and\or servers.

My hypothesis is that its 92mm
www.newegg.com has extremly cheap fans try them first.

Hope this helps

Thanks for reading!
