Portable PCs have become part of our lives and they have become powerful enough to cover our daily needs for computing applications. If you are among those who spent many hours behind their notebook PCs then you should consider having a notebook cooler, which will help you keep your notebook cool as you work, avoiding unexpected shutdowns due to overheat. Akasa has released the Gemini and the Libra series of notebook coolers for this purpose. The stylish product feature fans that provide cool airflow directed onto the PC base, keeping your notebook's internal fan noise to a minimum and allowing for a more peaceful environment.
Akasa Gemini cooler
The Akasa Gemini notebook cooler is ergonomically formed to ensure comfortable keyboard operation, and it is available in Satin Black and Polar White.

2. Akasa Gemini - Retail package
The Akasa Gemini costs around ~22 Euro (+shipping) and it is available in black or white colors.
Inside the retail box, the device is safely packaged in a plastic bag for dust protection. A USB cable and an printed manual are also available.
The product can be used with 12~15.4" laptops. It is made out of durable PVC plastic and it is light enough to be easily carried.
Two USB ports and an on/off switch are placed on the rear side of the device. The main USB port should be connected to your notebook in order to power the cooling fans, while the second one can power your mouse or your card reader.
At the bottom side you can see two 70mm fans and several anti-slip pads. A deep clicky sound was coming out of these fans while our laptop was in idle mode, although this sound was not audible when the laptop was fully operating.
When you place a 15.4" laptop on the cooler, all you will see cooler's front strip, since the laptop fits perfectly on the cooler's surface. Once put in place, the laptop is lifted by ~5cm on the front and ~2cmon the back, possibly making things a little bit uncomfortable, at least in the beginning.
3. Akasa Libra - Features
The Akasa Libra is another lightweight notebook cooler for use on the go. Specially designed air intakes and side recesses for easy handling allow the cooler to sit on your desk or lap were ever you are and effectively cool your notebook PC. The cooling performance will be enhanced when using the notebook on full load (i.e. gaming).
Airflow is generated by two quiet fans and a full size aluminum face panel dissipate the produced heat. Its ergonomically shaped aluminum surface with seven rubber non-slip pads ensure comfortable and stable notebook operation. The cooler is powered directly from your notebook with included USB cable. The ventilation fans can be also disabled through the available switch, allowing the cooler to work passively. The device also comes with an additional USB port for low- power devices (mouse, card reader etc), and it is available in anodized satin black or brushed aluminum.

5. Tests and Summary
We tried to find out how efficient a cooling product can be when you are using your portable PC in your typical daily tasks. The laptop we used in our test was an Asus A6JA with a 5400rpm HDD installed.
We run the 3D Mark '06 software three times and via the Everest Ultimate Edition we measured the temperature of the motherboard, the processor and of course the HDD. At the same time, the HDD was put under Everest's Ultimate Edition Burn-In Test in order to maximize the produced heat. Below is a table that illustrates the average/maximum temperatures of the various components of out notebook with the Akasa coolers installed and not installed.
For comparison, we have added the results of two other coolers by Thermaltake; the Ixoft Pad and the T200.

The test results are very interesting. Without any cooling solution installed, the Asus A6JA runs rather hot. The Akasa Libra seems to be the most efficient cooler on this test. It managed to reduce the overall temperature of the motherboard by 6.4 degrees Celcius. The overall gain at the raw CPU temperature is less (3.2 degrees Celcius), while at the VGA was kept cooler by 5.9 Celcius. In addition, the HDD temperature was 7.5 degrees Celcius lower with the Akasa coolers installed. On the other hand, the Akasa Gemini proved to be less efficient but still, it is a very good cooling solution.
To sum up, using any of the Akasa notebook coolers (Akasa Gemini/Libra) will reduce the overall temperature of your notebook. So both products do work. Especially if you are a hardcore gamer, the Akasa Libra seems to be the best solution. It feels more robust and its brushed aluminum surface make it look great. Priced at around €20 Euro both solutions look rather attractive purchases.
