The high score is rewarded with Winter Construction Plan for the Welding Process of Natural Gas Lon

Can I help you, what is the construction plan of manual paving subbase? Please elaborate and give the quantity of work.

There is no other way ... The only way is to use water cooling, and it can't be cheap water cooling. I'm only going to give you a plan to reduce the heat. There are specific brands and things. You'll have to pick for yourself.

Let's talk about why only water cooling can satisfy you. First of all, it's air-cooled... As long as it's a fan or something, it will definitely have a sound. It is not possible that the sound will disappear just because of the high or low speed. Because the rumors never go away.

Passive heat dissipation is absolutely impossible. First of all, both your you and the graphics card determine his popularity. Reactive doesn't meet your requirements.

In the case of dry ice. The lasting effect is too short. The price is too high. Not considered.

In the case of liquid nitrogen, the price is still much higher than that of water coolant. It is not a refrigeration solution that can be popularized, but it is now water-cooled. As long as the coolant is good. The cooling effect is basically the same as that of liquid nitrogen.

And the sound of water cooling is estimated to be in the range that you can accept. His decibel level is estimated to be the sound of a mosquito. It's a sound that you can only hear when you get closer. Hehe.

Friend! No more wasting time and brainpower!

Now the computers are out @silent@。

Buy a tablet with an SSD and you won't even have the sound of a keyboard and mouse.

Super quiet!!

Ha ha!!! 1

According to the requirements of LZ, I think that the silent system is not a simple fanless system, because the noise generated by the hard disk operation is the largest in many cases. Because the working principle of the hard disk causes this noise to be basically impossible to eliminate. Therefore, blindly building a fanless system is not advisable and expensive.

Fanless graphics cards, fanless power supplies, fanless coolers, that's all very expensive).

The so-called silence is as long as the sound is reduced to a range that is basically imperceptible to the human ear, and the following suggestions are given.

Considering that the LZ is a dual-core P4 (a well-known stove with a power consumption of about 100W at full load), I recommend muting the hard disk (adding a film buffer). Consider using a large-area heat pipe heatsink with a low-speed, large-size fan (12cm) to achieve better heat dissipation. Because the processor itself has a high heat, you can consider using dual 12cm fans, one blow and one suction.

As for the graphics card, you can consider installing a heat pipe heatsink and then installing a low-speed fan at the corresponding position of the case for active cooling, but because of the limitations of air cooling. The surface temperature of the heatsink should only be controlled at about 40, and the core temperature of the graphics card is around 60 (ps, so far I haven't seen a graphics card that can be controlled within 50 degrees when playing games, because the software detects the core temperature of the GPU, and it will take time for the heat to be transferred to the heatsink. Even if it is water-cooled, it can only be maintained at about 50 degrees Celsius).

For the above equipment, the CPU radiator is recommended to use overclocking 3 Nanhai (about 200 pieces) or Limin U120E (about 600 pieces, which is not cost-effective, stronger than Nanhai, but limited).

Fans can consider using all adda 12cm fans (about 30 yuan), with a governor (10 yuan) to adjust the fan speed at about 800 rpm.

The graphics card heatsink is relatively simple, find a large-area copper and aluminum heat pipe heatsink on Taobao to meet the requirements (generally about 60-80), and if the requirements are high, you can consider CoolerMaster's Z1 fanless graphics card heatsink (about 220 yuan).

In addition, after the modification of the machine, the wind direction of the 12cm fan should be aimed at the outside of the chassis. Timely heat dissipation from the chassis and control of the low ambient temperature in the chassis are the foundation of long-term stable use.

Intel and AMD's CPUs have high power consumption, and the motherboard chip level plus the heat dissipation of the graphics card are big problems. I've seen the old Saiyantu Ding fan not turn the graphics card without a fan to run. P4 has seen countless fans crash when they are a little slower.

There will also be a pump for water cooling. Finally, even if you use a CPU, the graphics card does not have a fan, the hard disk also uses an electronic disk, and the power supply always has a fan sound. I sometimes think that if I can find a glue that conducts heat and does not conduct electricity, install the motherboard, spray it with a layer, and throw it in the water tank, I don't think it will be a problem.

Maybe you can boil an egg or something. Haha, the reality is that you can only choose from a variety of silent versions of the device. Installed water cooling is still an outlier at present.

How ugly and ugly the water cooling equipment is after aging.

Put a refrigerator next to the computer desk, put the main unit in the refrigerator, make a hole in the refrigerator door to get out, and seal it with silicone rubber. ok!

It's not normal to add a copper radiator the size of a refrigerator, but the cost is less than four figures.

Go buy AMCP rapid cooling tablets and PPVR204V cold snorting tube (power supply only), your graphics card fan, CPU fan and power supply fan can be honorably laid off, pay attention to the tea near the case will freeze, if you don't want to drink cold, you have to pay attention, you are cool!

Semiconductor refrigeration, buy a semiconductor cooling block.

Find a large glass jar ......Pour in the bird oil ...... you saidBuy a portable hard drive with no sound, no, a USB drive or a memory card might be quieter, I mean no hard drive.

The display must be a liquid crystal floor ......The big head has a sound, and the mouse and keyboard seem to have a set of silent ones. What else?? Subwoofer, subwoofer?? You can't silence him, yes......It can be ...... with headphonesSorry, I'm too worried.

It seems like this is Europe...... rightBut the appearance is definitely ugly......Hey......Let's see for yourself......Guy, it's very demanding......o(∩_o...Ha ha!!!

Hehe. In fact, I am not in the line, passing by ......Mixed up.

The landlord asked for silence, but the contemptible person could provide a way to use semiconductor refrigeration chips.

Its biggest advantage is that it is small in size, noise-free, and power optional; However, it requires a good filtering effect of the power supply, which is highly susceptible to the influence of reverse current and reduces the power factor. However, the existing mainframe power supply can easily solve this problem (generally a separate power supply should be used).

The following are the ** of semiconductor coolers produced in Tianjin.

The landlord can choose "TEC1-127**" 12 as the rated voltage, that is, 12V; ** for the current value) series of construction, when the ambient temperature is not more than 40 degrees Celsius, the theoretical temperature (low temperature surface) is not higher than 0 degrees Celsius (after the installation of cooling fans, the temperature of the low temperature surface can reach 5 degrees Celsius), of course, the installation process, heat dissipation conditions, etc., restricts the temperature of the low temperature surface, as well as the heat dissipation efficiency.

First, the choice of refrigerator.

1. Graphics card, select TEC1 12703, voltage 12V, current 3A, power;

2. CPU, choose TEC1 12705 (or 12706), voltage 12V, current 5A (6A), power, use CPU cooling fan to dissipate heat to the cooler;

The total current and total power of the above two devices (** not high, not more than 40 yuan) are: 8 9A,685.

2. Heat dissipation. The heat absorbed by the cold end of the semiconductor cooler must be "pumped" to the hot end and then released to ensure the cooling effect.

For heat dissipation at the hot end, you can use the "passive" method, that is, the method of ordinary radiator, but practice has proved that this method has low heat dissipation efficiency and poor effect; Therefore, the "forced air-cooled type" is often used, but the noise increases.

Contemptible people believe that "forced" air cooling is still necessary, for example, the fan of the host power supply must not be dispensed without, the key is how to use the least cooling fan to achieve the best heat dissipation effect.

I did an experiment at room temperature 28 degrees Celsius:

1. Open the cover of the case, and measure the outlet air temperature of the CPU, host power supply and the surface temperature of the hard disk 30 minutes after turning on the machine.

2. Close the cover plate of the case, install an exhaust fan (the same size as the power supply fan) on the spare fan port on the back of the case, and make the air supplement from the front end of the case as much as possible (mainly to avoid "wind short circuit") to produce the "wind tunnel effect", and measure the outlet air temperature of the CPU and host power supply and the surface temperature of the hard disk 30 minutes after turning on the machine;

The measurement result is (using a high-precision reading-type electronic thermometer):

The first type is 13 degrees Celsius warmer than the second type.

It can be seen that accelerating the circulation of air inside the chassis is an effective way to reduce the internal temperature of the chassis.

It can be arranged like this:

1. Graphics card and CPU fan are installed at the heat dissipation end of the cooler;

2. Install an exhaust fan on the back of the case, together with the power supply fan, to increase the amount of air circulation in the case and take away the heat emitted by the cooler and hard disk in time.

Put your machine in the freezer. I don't know if this will meet your needs. There are no absolutes, and there are advantages as well as disadvantages in other aspects. The landlord himself measured.

Turn on the speaker with headphones.

Listen only to **, not to the noise.

o(∩_o...

Putting your console in a different room won't be fine.

Or stop all the fans inside and put the main unit in the refrigerator.

, you're not right, just go to the computer fan, put it in the refrigerator, and it's all right

Of course, it's all water cooled.,Those who say liquid nitrogen's xd:lz is not to be overclocked.,What are you doing with liquid nitrogen.,What's more, it's just an 8500 graphics card.。。。

LZ just buy a full set of water cooling, you can ask specifically, there are many people, you go to the overclocking heat dissipation area, just say that money is not a problem, ask for a silent heat dissipation solution, to ensure that there is enough YY answer.

Landlord: Do you think there's a compromise, but I'll give you a suggestion: using heat pipes might solve your problem.

300 yuan to buy a water cooling solution directly.

It's OK to buy a water cooling system! The cheap ones are about 100 yuan, and the expensive ones are about 500! A water-cooled system can connect CPU, graphics card and hard drive!

If you want to dissipate heat better, add liquid nitrogen to the water cooling system! Liquid nitrogen should be changed once a year at most! This is both silent and has a significant heat dissipation effect!

It's impossible for you to have no sound at all! Unless you're using passive cooling! However, passive heat dissipation is only suitable for some parts with relatively small heat generation!

If you're going to use passive cooling on a dual-core or quad-core CPU, HD3850 or N8800, then it won't take 6 hours to get reimbursed for the hardware! If you really want to have no sound at all, then just leave the computer on! I really can't help it!

CPU, use Tec1 12705 (or 12706) or buy a water cooling system to ensure silence.

A, you don't need to. The general pipe welding process qualification is at least twice the upper cover, and the lower cover is also doubled. But it also depends on whether it is a material, the high can cover the low. The low one can't cover the high one.

Semi-automatic cellulose welding? Are you doing long-distance pipelines?

There is no need to remake the welding evaluation.

Check JB 4708-2000 "Welding Process Qualification of Steel Pressure Vessels" and SY 0452-2002 "Welding Process Qualification of Oil and Gas Metal Pipelines" by yourself.

If the construction unit has pipe welding technology and welding process assessment, it should be familiar with the above standards and learn more.
