Arctic Cooling Arctic F12 TC, 120mm Temp Controlled Case Fan

Temperature Controlled High Performance Case Fans

The intelligent programmed temperature controller and accurate temperature detection in this fan make the ARCTIC F TC one of the best temperature controlled fans on the market.

Features

Temperature sensor on a 40cm long cable
Accurate case temperature detection
Cable can be positioned wherever it is required
Extremely quiet from only 0.04 Sone
Patented fan holder eliminates any buzzing sounds

Cutting-edge thermal management concept

Unlike other generic temperature controlled case fans, the ARCTIC F TC fan provides cooling according to not only the temperature, but also the overall need for cooling.

The revolutionary programmed temperature controller plays a key role. As shown in the chart, when case ambient air temperature is at a safe level between 0C and 32C, the ARCTIC F TC fan speed remains at its lowest (300 RPM). This is to offer adequate ventilation at the lowest noise level possible. The ARCTIC F TC is therefore completely inaudible (0.05 sone) at low temperatures which is a much quieter level than generic TC fans.

However, once a system is under load, the case ambient air temperature will go up rapidly. High performance and instant cooling is vital at this stage in order to eliminate the risk of overheating and causing system instability.

The ARCTIC F TC is programmed to achieve top fan speed at 38C. The fan responds to the rise in temperature swiftly within a critical 6C range, the RPM of the ARCTIC F TC fan increases from around 300 to its maximum of 1350 RPM (the steep curve in the chart). Heat is then dissipated from the case rapidly in order to achieve immediate cooling. As a result, the case air temperature remains at 38C or below and thus the possibility of having a system failure can be virtually eliminated.

Highly flexible sensor on a 40cm cable

The accurate temperature sensor of the ARCTIC F TC is equipped at the end of a 40cm cable. This gives much better flexibility when choosing the most appropriate spot where users would like to have the temperature detected.

FAQ

How do I measure fan size?
The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.

As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.

If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.

I received a small cable (resistor) with my fan; what is it for?
The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.
How can I tell which way the air blows through the fan?
Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.
Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?
Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.

The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.

Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.
