Introduction to the Cooler Master Gemini II S524 CPU Cooler

Proper cooling of computer components is one of the most important procedures to consider when building a new rig. The first thing that comes to mind when it comes to cooling is making sure the CPU is operating at a satisfactory temperature, but many seldom go any farther than that. What about extra cooling of your RAM, North Bridge or even the phase power MOSFETs of your motherboard? Yes, these things should be cooled as well. Whether it is to extend your overclocking ceiling or to help prolong the life of your components. Cooler Master has adding the Gemini II S524 to their line of CPU coolers and it helps achieve all of those.

Cooler Master’s take on the Gemini II S524

Gemini II S524 features a larger Heat sink for improved cooling performance, and increased memory module clearance to support high end memory modules featuring large Heat sinks of their own. It comes equipped with a modular 120mm fan with an ideal noise performance ratio throughout its supported range of rpm. It can be upgraded to a 140mm fan to further boost its cooling performance or opt for a super low noise, low rpm fan.

Closer look
The new Gemini II S524 is the rebirth of the Gemini series that was known for expanding the cooling capacities of the typical CPU cooler. The Gemini line was designed to help cooler other components of the motherboard, like the North Bridge and memory. Yes, the coolers are just this wide to cover other areas of the PC in order to keep it running cool and operating at its highest level.

The Gemini II S524 may look large and heavy but far from it. The cooler weighs 490 grams and measures 5.7 x 5.7 x 4.1 inches. Installing in a case as large as a mini tower or large should not be a problem. Some other styles of cases may or may not have an issue with installation.

The new S524 follows in the same footsteps as it has a tabletop design where the fan sits on top of the cooler and blowing down over the surface of the motherboard as well as the CPU. The fan used measures 120mm and is PWM controlled. According to CM the fan speed varies between 800-1800 RPM and has a decibel level of 15-31 dBA. The mounting brace for the fan is large enough to support an upgrade to a 140mm cooling fan.

The fins that made up the cooler are made of aluminum which is pretty normal. About 1/3 of the fins extends from the top of the cooler to the base while the rest help to make up the upper half of the cooler. The arrangement of the fins is simple and not angled or designed in a way were air is directed in a particular direction. The density of the fins is enough to allow sufficient airflow to travel to the lower regions of the cooler.

The S524 uses a total of five nickel-plated copper heat pipes to help move heat away from the processor. The pipes measures 6mm in diameter.

The base of the after removing the protective plastic sheet came out in better condition than the CM 612 PWM we review a few weeks ago, leaving no residue behind to remove. The overall condition of the surface of the base is flat and partial shiny.

Stress Testing

For our testing we will be using the following procedures and parameters to acquire the necessary data:

  1. Thermal compound used is Arctic Silver 5
  2. Idle temperatures are recorded after the system has been allowed to idle for thirty minutes from the point Windows has finished loading.
  3. Load temperatures are recorded by running LinX for twenty-five minutes on all available threads.
  4. Real Temp is used for the recording of all temperature sensor reading.
  5. PWM function is disabled via BIOS to allow the fans to run at full speed.
  6. CPU model and overclock speed used for testing are outlined below in "Test Hardware".

Test Hardware:
Motherboard: ASUS P67 Deluxe B3
Processor: Intel Core i5 2500K @ 4.5GHz w/ 1.3 voltages
Ram: Crucial 2133 4GB Dual Channel (9-10-9-28)
Video Card: ASUS Radeon HD 5870
HDD: Hitachi 1TB
Power: Thermaltake Tough Power XT 850 (Sponsored by Thermaltake)
Case: Open air
Cooling: Cooler Master Gemini II S524

Testing Results


Conclusion

The Gemini II S524 is not Cooler Master's answer to the super coolers we have previously reviewed here at Pro-Clockers. However, it is the answer to superb cooling of addition components around the CPU socket, which no super cooler does. Just what is it the S524 does that many others do not? Well, how does possibility cooling your ram, North Bridge or power phase MOSFETs sound? The S524 isn't going to win any awards in the maximum cooling performance category but it does help to maintain the life of other components that are often neglected. This is ideal when air circulation is an issue in some air restricted cases, like HTPC models.

If a portion of the above statement makes it seem like the S524 isn't a good cooler, well that is far from what we are trying to say. Cooling some of today's popular processors like the 2600K from Intel and the 1090T from AMD is no easy task. The S524 handles our overclocked and overvolted Core i5 2500K with no problem.

Another nice feature of the S524 is the lack of noise from the fan, even when the system is under load. The S524 is geared towards those that want decent performance and low noise, which is exactly what we got out of this testing session. If you can get this cooler to fit in a case with air restrictions then at least you'll know those important components on the motherboard will survive.
