3. mining? 580 must be better, but it's more expensive. Generally speaking, 470 mining is the most cost-effective. It can be converted into 570 by brushing the BIOS. The investment cost is low. If you really want to mine, you should go to Sichuan. There are many hydropower stations there. The electricity charge is super cheap, and the power of hydropower stations can't be used up. They have to thank you when you use electricity
4. Rx580 4G, performance can be about 25% different
5. ASUS rx580 graphics card, equipped with 8GB gddr5 mass video memory, video memory frequency of 8000 MHz, with 7 + 1 phase SAP II super alloy power supply design, can enjoy a reliable experience no matter in general daily use or in the execution of bone ash level games or overclocking! With aura, players can freely set their favorite light colors and effects according to their own preferences.
6. The rx470 brush rx5802048sp can improve the performance by about 10%
if it is the rx470d brush after the core is turned on, it can increase the performance by 15%
but the power consumption will increase a lot. Even if the fan is adjusted to 100%, it may not be able to suppress the heat dissipation in summer, and it is easy to reach 90 degrees
so it is almost the same to brush rx570

RX 580 vs RX 470, in short, rx580 wins.... The following figure shows the comparative test of various games:
8. Enter the BIOS to adjust the speed of the fan.
first power on, then press the Del key on the right keyboard, the system will enter the COMS settings, and then press up and down to select PC health status, in which CPU faneq speed control is fan speed control, and select enabled to turn on the speed control function, If there is no CPU fan EQ speed control, it may also be CPU fan control by. In short, it is an option for fan adjustment, which is usually an option with fan words
enter BIOS --- power --- hardware monitor --- set the CPU q-fan control option to enabled. The CPU q-fan profile option appears. When it is set to [optimal], the CPU cooling fan will automatically adjust the fan speed according to the case temperature. If it is set to [silent], the CPU cooling fan will operate at the lowest speed on the premise of quiet. If it is set to [performance], the CPU cooling fan will operate at the highest speed on the premise of heat dissipation efficiency
however, it depends on whether your machine is this kind of BIOS, and the best way is to read your motherboard manual<
best answer
Step 1: to use the intelligent CPU fan control function, you must first set the "CPU fan control by" in the BIOS of the motherboard to smart
Step 2: no matter which model of LGA775 CPU you use, it is recommended to set the CPU fan start temperature at 24 ~ 35 ℃. If the initial temperature of CPU cooling fan is set too high (e.g. above 50 ℃) and the start PWM value is set too low (e.g. about 800rpm PWM value), the heat generated by CPU can not be discharged in time, resulting in overheating and crash
Step 3: the CPU fan off (℃) setting is very useful after the system enters S1 standby mode, because the CPU load will be minimized after the system enters S1 standby mode, and the CPU temperature will also be reced (usually only about 20 ℃). Only the heat sink can effectively discharge the heat generated by the CPU, and no cooling fan is required. Therefore, it is suggested that the value of this item should be set between 16 ℃ and 20 ℃
Step 4: for the value of CPU fan full speed (℃), it is recommended to set it in the range of 60 ~ 64 ℃ (no higher), because the maximum normal working temperature of Pentium4 or celeron d of most LGA775 interfaces is about 75 ℃. If the CPU works for a long time beyond or very close to this limit, it will cause damage to the irrecoverability of CPU
Step 5: when adjusting the start PWM value, make more attempts, because the ratio of fan speed to PWM value is different for different CPUs. However, it is recommended to adjust the starting speed of CPU fan to more than 1100rpm (some brands of motherboards will give a zero speed alarm or shut down automatically when the speed of CPU fan is lower than 2000rpm, at this time we can turn off the speed alarm function of CPU fan), and the approximate range of PWM value is between 15 and 35
Step 6: generally, the step size of slope PWM should be set below 16 PWM value / ℃, otherwise, as soon as the CPU temperature rises by a few degrees Celsius, your CPU fan will sound like a bell<
an effective method to remove computer fan noise
Wen / Xue Mingming
I do computer maintenance work, and I have made some attempts to remove computer noise in the practice of computer maintenance for many years. Computer noise is mainly proced by CPU fan, graphics card fan and power supply fan. My method is to rece the supply voltage of the fan, that is, to rece the speed of the fan. I have done this transformation on several computers, and the temperature of each part in the chassis is basically the same as before. The results show that the surface temperature of the CPU radiator is 37 ℃, the surface temperature of the graphics card radiator is 36 ℃, the temperature of the power outlet is 37.5 ℃, and the maximum temperature in the whole machine case is 35 ℃. The temperature in the case fully meets the specification requirements of Intel's "38 ℃ case". This method is simple and practical, so I recommend it to you
the principle of the step-down circuit is shown in Figure 1. The + 12V voltage from the red line of the fan interface is connected to the input 1 pin of the three terminal voltage regulator 7806. After the internal circuit of the three terminal voltage regulator 7806 is step-down and stabilized, the + 6V voltage is output from its 3 pin to supply the fan. Pin 2 is the common ground terminal of the input and output terminals of the three terminal voltage regulator 7806, which is connected with the ground terminal (black wire) of the fan interface. The specific installation steps are as follows: (1) cut the red line from the fan interface to the fan from the middle 2) Connect the cut red wire at one end of the fan interface to pin 1 of the three terminal voltage regulator 7806 3) Connect the cut red wire at one end of the fan to the three pins of the three terminal voltage regulator 7806 4) Connect the black wire from the fan interface to the 2 pins of the three terminal voltage regulator 7806 5) The difference between the additional power supply fan and other fans is that one pin of 7806 is connected to the yellow line of power supply, and two pins are connected to the black line of power supply
The buck circuits used by the three fans are the same, but e to their different power, they should be treated differently: (1) the CPU fan is the most powerful of the three fans, so the three terminal voltage regulator 7806 should be connected close to the fan and naturally suspended in front of the fan, so that the air from the fan can heat the three terminal voltage regulator 7806, and the specific location is shown in Figure 2 2) The power of the power supply fan is small, so it is unnecessary to consider the heat dissipation problem of the three terminal voltage regulator 7806. However, for computers with poor matching between the power supply and the whole machine (that is, insufficient power supply) or too many things installed in the whole machine (for example, two optical drives and two hard disks are installed), recing the fan speed will cause poor heat dissipation, A power fan can be added outside the power supply to use with the original fan at the same time. The additional fan is directly connected to the computer power supply after connecting the three terminal voltage regulator 7806. The yellow line in the computer power supply is 12V, and the black line is the ground wire. The specific location is shown in Figure 3. Although some computers need to add a power supply fan, it can prolong the service life and remove the noise after recing the speed. In fact, it is very cost-effective and worth trying 3) The fan of the video card is small, but its speed is high, which leads to a lot of noise. Therefore, we need to remove the original high-speed small fan, replace it with a fan with larger volume and power, and maintain the original heat dissipation effect. After the replacement of a large fan, it is very important to fix the large fan. At least two (diagonal) screws should be used to fix the fan on the radiator. When it is impossible to fix the fan with screws, double tube universal glue or stick glue can also be used to stick the fan on the radiator. The video card fan can be connected to the original interface, but it is better to connect to the power supply through the adapter. The specific location is shown in Figure 4 4) The structure of power supply and external power supply fan can be seen from Fig. 3 and Fig. 5. According to the cooling hole of power supply shell, the external power supply fan can also be installed at the lower part of power supply. It can be seen from Figure 6 that the installed three terminal voltage regulator 7806 is suspended in the chassis. Make sure that they do not contact with the circuit board and all metals 5) The purpose of recing voltage can also be achieved by using series resistance. However, e to the different sizes of fans, the rated current is different, and the requirements for the resistance value and power size of the resistance used are also different, so the calculation is troublesome. The resistance calculated according to the formula can not reach the expected value of recing voltage after being connected into the circuit, so 7806 is better, Just connect according to the picture.
