    I can see people's faces, but I can't see them clearly.

    Your requirements seem to be a little too high.

    1. Let's talk about this "one kilometer": - 1000 meters distance, if we look at a person with the naked eye, the height of the person is like a Chinese character". You have to use a kind of hand-held telescope to see this clearly."

    The size of the person's face - this problem, I specially found an authentic, more than 1,000 military telescopes to experiment, at a distance of 500 meters, can only easily see the male and female at the same time, barely see the appearance of this person's face - if you know this person, then you can recognize who he is. This is still at 500 meters.

    And to see the details, expressions, and wrinkles of his face clearly, this is something that cannot be done with a telescope in hand.

    It's 500 meters, — a megalomb — you're asking about a kilometer, that's 1,000 meters! Makes that clear, right?

    2. Let's take a look again, what kind of telescope can achieve the effect you said?

    This starts with the question, at what distance can you see a person's face with the naked eye? I'm afraid I guess it's at least 20 meters! From within this distance, we can really observe a person's face carefully.

    So, looking at the distance of 1000 meters, how many times does it take to get closer to 20 meters? Theoretically, 50 times. But in my experience, when looking at the scenery on the ground, the image quality starts to drop "very obviously" when it exceeds 30 times, because the air starts to boil, and basically 30 times is not suitable for looking at the ground.

    Generally more than 20 times is more suitable for high-magnification observation of the ground multiples range.

    Therefore, your requirements, even with desktop telescopes, are difficult to meet, this is not a matter of money, but we live on the earth, and some things are disturbed by the earth's environment.

    3. The above introduces some telescopes and the problem of multiples, but in terms of multiples, it is precisely where many inferior products are used to mislead consumers! So there are a couple of things to highlight:

    Now, there are many fake and inferior products on the market, accounting for more than 90% of the market, as well as false propaganda, such as "night vision", "infrared", "high magnification", "military", "Japanese cherry blossoms", "Russia" and so on, it is recommended that you understand the basics.

    Particular attention is paid to the issues related to multiples, military, night vision, etc., that is, the introduction of some common false propaganda.

    There are too many counterfeit and inferior products, and such products also have a characteristic, they like to use "high magnification" to deceive people, such as "15 times", "20 times", "30 times", "50 times", "999 times" - handheld telescopes, are all deceptive, not even regular products.

    4. Dude - when you asked this question - it seems that you didn't realize how scary the requirement of "1000 meters to see people's faces clearly" is :)

Find the Quick Launchbar.

Friends who have come all the way from XP and Vista must have attached great importance to the Quick Launch Bar, which has saved us a lot of time as a centralized place for application startup files and folders. After entering Windows 7, with the advent of the super taskbar, the previous fast launch bar was removed, which made friends who are used to the fast launch bar feel very unaccustomed. Although the new Super Taskbar also has the function of a quick launch bar, some people still want to get it back. >>>More

In fact, the CPU 50 is normal, but in view of the situation you said, it may be a problem with the fan, and the noise in the case may be that the fan is out of oil, but the original fan for three months should not be like this, so I think the easiest way is to take a look at the advanced BIOS, the fan speed, the CPU temperature is normal, if it is normal, open the case to see, if it is still normal, do not cover the case cover first and wait for the problem to look again, but it feels like there should be no problem.
