This heatsink has previously had value for money, but I would like to give more intuitive and detailed usage reports and purchase advice for reference. Last September started Dell Inspiron 7559-2512BLK, classified as a game. Due to the need to render video and large-scale 3D games, it is more concerned with heat dissipation. Learned that this laptop cooling short board is not enough at the bottom of the amount of air into the air (the case of a significant drop in the temperature of the computer, that is, the bottle is obviously cooling), and taking into account the 7559 has 3 side outlet, and noise problems, they gave up the ventilation type heat sink. My selection criteria are: not too expensive, not ugly, not light, dark. Therefore, after some screening, he decided to purchase the heatsink as shown in the title. Unfortunately, at the time, it was necessary to render a video, and the price of the radiator was at a high of 69 yuan. After thinking about it, it decided to start as soon as possible. Speaking of it, I personally think that the camouflage version is really ugly... actually worth 10 yuan. Radiator designed a "borrow one" USB interface, the actual use, it can only say enough, better than nothing. The work of the interface is general and the depth is not enough, so the inserted cable can be shaken by the external force. In other words, it is not tight. The switch is also relatively loose, the sense of confirmation is very small, often dialing or not dialing. Since the inlet of the 7559 only corresponds to two large 14cm fans, I generally only open to the first gear in winter to avoid cold hands. Of course, if I'm too lazy to go back and feel the position of the switch, I'll go straight to the end. It is a relatively big problem whether the switch is so easy to damage. People who bought with me also reflected that there were depressions in the net mask, indicating that this may not be a case but a common problem. Or, my non-infectiousness transmitted him In order to reduce the number of variables to be more intuitive, to watch the vanguard of all the special effects as an example, the 7559 fan noise is divided into 6 files, recorded as a day when idle, when the notebook self-diagnosis fan is fully opened when the 6 file, the test object for the graphics card Temperature and fan noise levels. On the desktop, do not pad radiator: fan noise about 4 files, graphics card at about 65 °C; Pad radiator, but no fan: fan noise about 3 files, graphics card at about 63 °C; Pad radiator, only open 14cm big fan: fan noise 2 files, the graphics card is about 59 °C; Pad radiator, fan full open: fan noise 2 files, graphics card at about 58 °C. It is worth noting that the radiator itself is also slightly noisy, approximately equivalent to the 7559 fan 2nd gear recorded in the test. In general, the noise is reduced. It can be seen that for the 7559, the role of this radiator, in addition to cooling, is to reduce noise; In addition, the cooling effect depends on the bottom of the notebook inlet, such as 7559, 10cm fan does not What to use but for (for example) Shenzhou Z7 at the bottom of the huge air inlet, the effect of four fans will be much better. Taking all the factors mentioned above together, I gave the following ratings for this notebook cooler: Appearance ★★★★☆ It feels cool enough, but in fact I personally prefer the design of some of the coolness. Although this is no longer a good pick. Portability ★★★☆☆ After all, is the notebook accessories, or to evaluate the portability In fact, the thickness of the X6 is not small, but relatively light, and similar products are nothing more portable, in addition to exhaust type radiator. On the other hand, there should not be a demand for laptops and radiators to be back and forth every day. Performance ★★★★★ The wind pressure of the radiator is not really large, but the fan diameter is large. I think the air volume is actually not small, and it can meet my cooling needs. Of course, the wind pressure as an electric fan is still unlikely. Cost-effective ★★★☆☆ Yan value is enough, enough air volume, is the details (such as interfaces, switches) work in general, if you want to 69 yuan or 79 yuan high start, then the price can only give three stars. The X6 has had a good price of 59 yuan or even 49.9 yuan. It is better to wait and see. If you need a tough look, reduce fan noise, increase the amount of air entering the bottom, increase the notebook, and the demand is not urgent, it is recommended to wait and see until the good price of 59 yuan or less to start.

What is high frequency PCB?
High Frequency Board refers to a special circuit board with a higher electromagnetic frequency. It is used for high frequency (frequency greater than 300MHZ or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meter). The copper board is a circuit board produced by using part of the process of the ordinary rigid circuit board manufacturing method or using a special processing method.

1. DK should be small and stable enough, usually the smaller the better. High DK may cause signal transmission delay.
2. DF should be small, which mainly affects the quality of signal transmission. A smaller DF can reduce signal loss accordingly.
3. The thermal expansion coefficient should be the same as the copper foil as much as possible, because the difference will cause the copper foil to separate when the heat and cold change.
4. In a humid environment, the water absorption rate must be low, and the water absorption rate is high, which will affect DK and DF.
5. Heat resistance, chemical resistance, impact resistance, and peel resistance must be good.
