About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

KLIM Technologies
KLIM Wind Laptop Cooler

Product description of the manufacturer:

The KLIM Wind laptop cooler from KLIM Technologies was developed to effectively prevent laptops from overheating, thereby extending the performance and service life of the devices. Especially with gaming laptops or demanding applications, high temperatures can impair performance. This is where the KLIM Wind comes in with four powerful fans that provide even and powerful cooling. Thanks to its robust design, the cooler is suitable for various laptop sizes.

The efficient cooling performance and the pleasantly quiet operation should be emphasised. The device remains stable and ensures reliable heat dissipation. The simple design, which in combination with the high proportion of plastic may not be visually appealing to some users, could be criticised. Overall, however, the KLIM Wind impresses with its reliability, high performance and good price-performance ratio.

  • Efficient cooling performance thanks to four powerful fans
  • Quiet operation, ideal for gaming and office work
  • High compatibility with laptops of different sizes
  • Lots of plastic

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The KLIM Wind laptop cooler presents itself with a functional and modern design that is reduced to the essentials. Visually, it remains rather simple, without eye-catching design elements or special accents. While this may be an advantage for some users, we would have preferred a more appealing design at this point.

The workmanship is high quality, with clean edges and precise manufacturing. There are no recognisable processing errors or unclean transitions, which indicates careful production. The device is made of robust plastic, which ensures a long service life. However, a metal component or a more elegant surface structure could have further enhanced the design.

In terms of stability, the KLIM Wind is impressive across the board. The construction is very solid, so that even larger laptops stand securely on the non-slip surface. The well thought-out design ensures that the device remains stable and reliable even in longer usage scenarios.

In the practical test, the KLIM Wind laptop cooler was tested for its performance in various scenarios. A key criterion was stability on different surfaces, including a wooden table, a glass shelf and a carpeted floor. The device demonstrated a high level of stability on all tested surfaces, with only a slight wobble being observed on particularly smooth surfaces. The cooler also performed excellently in terms of compatibility with various laptop sizes. Models between 13 and 17 inches fitted easily on the support surface, the fans always remained free and worked without restrictions.

The efficiency of the cooling was particularly impressive. In long-term tests with demanding applications, the temperature of the laptop was reduced by 10 to 15 degrees, which is a noticeable relief for the device. The fans ran quietly and evenly throughout, without making any disturbing noises. Even after several hours of operation, the performance remained constant without any overheating problems. A small point of criticism is the slip resistance on very smooth surfaces, where a minimal shift was occasionally noticeable. Overall, however, the cooler was convincing in all relevant test categories and confirms the manufacturer’s promises.
