What kind of radiator do you need in the era of low power consumption
What is the Requirement?
First of all is Noise:
Noise is a subjective problem, and for the average consumer, it is impossible to quantify it. But there is one job that must be done at the time of purchase, and that is-listening. Connect the radiator to the power supply (the radiator seller usually has a radiator fan interface) to make the fan work normally. Then people stand about 50cm away from the radiator. If you can't hear the fan noise or the fan noise is very subtle, then we can consider this radiator to meet the demand. On the contrary, if the noise of the fan at 50cm is still "sounding", then this product is not worth considering.
Pay attention to volume: Don’t buy a radiator that can’t fit into the case or a radiator that is very difficult to install. Although most of the dual-core silent radiators of around 100 yuan are relatively small, they have to be tailored according to the actual situation of their chassis. Take the original radiator as a reference. In contrast, products that are too high or too large do not need to be considered, unless you are using a large tower case.
Price: Obviously, whether it is for the needs of HTPC or for our own silent needs, we don't have to pursue large heat pipes or water-cooled radiators that cost hundreds or even thousands of dollars. It is precisely because of the significant reduction in processor power consumption that we do not need to pursue the extreme heat dissipation performance, and can be used. After all, the focus is on silence. Therefore, we believe that silent radiators within one hundred yuan are the key points that need to be considered. In fact, from our survey, most users are also most interested in silent radiators at this price. Here, we call it the "low-end dual-core silent radiator."
Material and rated current should not be ignored: the rated current is generally directly related to the fan speed. According to our experience, under normal circumstances, an 8cm or 9cm fan with a good mute effect can maintain a good mute effect (speed around 2000rpm) at a current of 0.1A to 0.2A, while a 12cm fan can generally be kept low within 0.3A. The mute effect of speed (not absolute, for reference). If you find that the rated current of a radiator is too large, it is likely that its speed is also quite amazing, and you have to consider it.
Correctly interpret the radiator label: No matter what you buy, reading the manual is always the first thing to do. The label of the radiator can tell all the parameters related to the performance of the radiator we need. Under normal circumstances, the label of the radiator should include the processor model supported by the product, the material used in the product, the diameter and speed of the fan, the nominal noise value, the electrical performance parameters of the fan (voltage and current), and the maximum air volume (air flow). ) And information such as the type of power connector. If you find that some heatsinks are unclear, such as fan information is not given, noise values are not marked, or the maximum supported processor model is not marked, then such products are not worth considering at all.
