Superior Cooling Performance
An interchangeable 120 mm PWM fan in combination with 4 direct touch heatpipes and a 48-fin heatsink enable the Freezer i30 CO to deliver outstanding cooling performance and improve heat dissipation from the CPU. According to the test results from Hardware Secrets, its superior cooling performance surpassed the stock cooler and similar models by up to 34 degrees.

Low Noise
The test in Tom's Hardware has shown that the Freezer i30 CO is the quietest cooler in their roundup. Thanks to the PWM control, the fan speed adjusts according to the CPU temperature and thus the noise level remains at an absolute minimum which qualifies it as a silent cooler. Click here to see how the PWM control settings can be changed according to your performance and noise preference.

Sturdy Mounting Mechanism
There is no need to worry about the weight of this muscular, yet gentle cooler. The Freezer i30 CO is using a durable steel mounting clip and comes with a bundled back-plate*. As a result it has an excellent mounting stability and is fully transport-proof. * For Socket 2011, it is compatible with the existing back-plate
Direct Touch Heatpipe Heatsink
Rubber Vibration Absorbers
The Freezer i30 CO heatsink consists of 4 double-sided direct touch heatpipes, 8mm in diameter. A patented process (20 2011 000 71.8) allows us to pack the heatpipes without gaps and thus increase the contact surface and achieve better flatness by precision machining - both leading to an improved heat transfer.
4 Mounting Directions
Interchangeable Fan
Continuous Operation
"CO" stands for Continuous Operation and makes the cooler suitable for PCs with non-stop operation like servers. The Japanese dual ball bearing used in the "CO" fan reduces rotational friction considerably, is significantly less sensitive to dust and high temperature and hence up to 5 times more durable than other bearings.

"Excellent thermal performance with minimal noise"
"Performance:Excellent thermal performance with minimal noise, even at the highest fan speed despite limited motherboard support and additional fan mounting options."

"The Freezer i30 is the strong, silent type, able to withstand plenty of heat, even with just a single fan. The build quality is excellent, as expected from a flagship CPU air cooler, even if it is priced for the mainstream segment. Installation was swift and the mounting kit doesn't apply too much unnecessary pressure on the motherboard."
The Freezer i30 offers great performance to price ratio with a simple installation process. The PWM fan is so quiet and barely noticeable.

"Brilliant performance"
"Noise is a modest 44.0 dBA. At the minimum fan speed of 400RPM, noise output falls to a whisper quiet 30.8 dBA - quieter than a fart in the vacuum of space! Well, not quite."
Frosty Tech
"Performance of the Freezer i30 is astounding, cant find anything better than this near this price range."
ARCTIC A30 is extremely quiet and it cools my processor better than any other of our coolers in comparison.

"Quieter than a fart in the vacuum of space! "
"The sound emission is really very low, thanks to the fan ARCTIC F12, which emits 22.5 decibels at full load. I would venture to say that the ARCTIC Freezer i30 is one of the quietest sinks ever, comparable to silent NZXT Havik 140."
HW Master
"The i30 is able to keep the temperatures at safe levels under full load (in Idle: 14 delta; at Load: 51 delta.)It is a solid choice for someone looking to do some overclocking without spending too much money on cooling."
"Excellent performance without compromising noise! Great!"
"Despite the seeming simplicity of its design with four heatpipes and direct heat dissipation efficiency is at a high level. In fact, we face a very versatile solution that allows us to exploit the highly overclocked CPU under normal conditions with an average noise level or to build ultra-quiet PCs in case of normal operation or chips."

"The Freezer A30 is very quiet, I could barely hear any noise from 1m distance and shows very good cooling results with a single fan."
In a push configuration, Freezer A30 produced great numbers for an Over Clocked 965 AMD processor. But we were amazed by the results when we changed to a pull configuration, and the core temperature dropped an additional 17 degrees C!

The LGA 2011 socket of my motherboard looks different. Will it fit my Freezer i30 CO?

There is a chance that the Intel LGA 2011 socket on your motherboard looks different from the others (see example below). Please ensure that there is a metal plate around the screw holes (see left), otherwise damage to the motherboard may happen during the installation.



Special case

The PC is reporting a low fan speed during booting.

Your PC may send you a CPU Fan Speed warning when starting the PC if the fan speed is lower than the default minimum value. If you do not wish to receive this warning in the future, you may enter the BIOS to reset the minimum value or disable the function completely.

As shown in the example below, you can adjust the settings under Power -> CPU Fan Speed warning. By setting the value to 800 RPM, you should avoid any warnings of this kind in the future.


Intel LGA 2011(-3) compatibility (square / narrow ILM)?

For the socket LGA 2011(-3), Intel specifies two different formats: SQUARE ILM & NARROW ILM. Please note that Freezer i30 CO is compatible to LGA 2011(-3) refer ONLY to mainboards fitted with SQUARE ILM (80 x 80 mm spacing).
