The graphics card 7750 is also considered to be a good point of graphics card that can be bought within a thousand hours now. It has been bought for more than two years before tossing.
Sound card this is quite good support for the rack tuning what was previously played recording
Memory is a server bar that was removed by a 500-buy friend's unit
The power supply has just changed. . . . The original 150W power head suicided when it was installed for a few days.
The reason was that gen8 had been on the table and had been stuffed into the cupboard because the cabinet was not well ventilated and the back was a warm valve. So the boot is 90 degrees. The door of the cabinet cannot be closed, and it restarts itself after an hour or so. Above 110 degrees went. And when it was originally on the outside table, the temperature was extremely high. The fan runs at almost full speed. You know gen8 on hand. It is the sound of a boot fan.
Has always endured use. Then I watched the 200-block water cooling program at the station. Think it changed. Then he entered the pit. True --- pit.

The standard first generation, on the water cooling can be seen, the inside of the silicone curing is very powerful (water temperature and cpu temperature difference). As early as possible, the original radiator should be able to be used from 80 degrees to 60 degrees.

The original plan: four cold rows and four cold fans. A small tank is a submersible pump. Two cold head pumps inside the main unit.
Put the water-cooling drain on the top of the cabinet and then add a submersible pump inside the tank. Inside the CPU, a pump card is on a pump, and then it is less because it is the first time to do water-cooled homework. The head of the entire system is responsible for only one submersible pump. Large wattage is the circulation pump, which can only increase the flow of water. The three pumps plus one no-load (although the cold row) can only reach a height of 1-5 meters, and the amount of water is very small.
The water pipe in the stairway is the original test head
Very disappointed. Afterwards, it was a good idea to see those good DDCs.
Then made a plan, and now I personally feel the best solution.
The circulation pump on the CPU circulates the pump to give up the water. The hot water comes out directly into the water-cooled head built in the semiconductor cooling sheet, and then the inlet tank is again driven into the host through the submersible pump.
Taking the 12705 cooling chip as an example, the power consumption is 50 watts and the ambient temperature is 28.5 degrees. One liter of water at 28 degrees can be reduced to 15 degrees, and then use the cooling plate to cool the 15 degrees of water into the host. After talking to the seller, the seller said how it can be done in the summer. But in the winter, for example, if you only have 15 degrees of room temperature and then the water that comes out of it is likely to freeze, you must replace a larger water tank. Or open and stop this.
Later, I went to the group and said the idea to everyone. Everyone said, consider the dew effect. Cpu80 degrees coming in at a water temperature of 5 degrees for a long time certainly exposed. One night, gen8 is sure to enter the water.
Later discussion of the program is: The graphics card cycle out of the hot water into the cpu, cpu cycle out of the hot water, a modified 5L Nongfu Spring as a pure bucket, and then pumped from the bucket to the graphics card up. This is a group of hot and cold exchanges. Then make a group of cold and heat exchange, cold water from the semiconductor cooling sheet into the barrel. In the same way, hot water pumped into the cooling plate. Cool the water in the bucket. For example, in three hours, the temperature in the barrel reached 30 degrees and the refrigeration plate was turned on to begin cooling. After the water temperature in the bucket is lowered to 15 degrees, the cooling plate is manually turned off. (Actually, I added another group. The friend said that he was the cpu of the fx-8300. It was also externally water-cooled. Two pipes, two pipes, one water and one water came out of the back of the cabinet. Then I took a wash basin. Said to start at 6 pm, until 1 pm, put the pot into the pot had to add water to it. About 3L water, boot for 7 hours, from the 8 degrees of tap water to 28 degrees.) In other words, 5L pure water bucket, if used for 10 hours, 8 degrees of tap water is raised to 20 degrees. Can completely replace the cold row.
Popularity: dew point, dry bulb temperature - (100-relative humidity)/5 Example, actual air temperature 30 degrees relative humidity 60.
The dew point is approximately equal to 30-(100-60)/5=28 and the dry bulb temperature minus the dew point temperature is 30-28=2
Change to water cooling, actual cpu temperature 60 degrees, relative humidity 60 degrees,
The dew point is approximately equal to 60-(100-60)/5=58 Then the dry bulb temperature minus the dew point temperature is 60-58=2
Theoretically, if the water is more than 2 degrees, such as three or four degrees of water, the outdoor temperature is 30 degrees, the cpu temperature is 60 degrees, and the water temperature is 3 to 4 degrees. ! ! You are big swindlers.
Therefore, the water coming out of the cooling plate directly into the CPU and the graphics card is not a problem. And so on, in life's common sense, at 30 degrees in the summer, a bottle of drink is taken out of the refrigerator and put outside. It looks like it will indeed show up. The temperature in the refrigerator is 4 degrees and the outdoor temperature is 30 degrees. Am I mistaken in the formula? Still wrong?
Because of this problem, there are still two hundred oceans I can not afford to buy. So we had to go through the original plan.
Open up
Cold row of anhydrous 233 grams
Cold row filled with water 416 grams
The water content can be calculated to be 183 grams. Calculate it by 200ml.
Connect fan and hose. (later it was too wide, it changed to vertical)
There are 30 and 45 in the 2.5M screw market but there is no 32. Had to buy a 45 and then use pliers for short use.
Water valve buy less, the best external water-cooled four, the host water a water-cooled system to the host a water, a host water, water-cooled system to the host water. I bought two of them so that the host does not leak when disconnected. But the cold exhaust system has to take the basin. Then fill it with water again.
Graphics card pump one cold polishing (actually prove this is a garbage pump, or I bought sticky silicone too rubbish. Behind the problem)
Apply a light layer and hold the hard disk
Remove the original fan and stick it to the heat sink with sticky silicone. (Because the original fan of this video card is back buckled, this water is too cold, so you can't use the screw up, only use silicone to get on)
CPU water cooling pump installed
No place for pipe out
Wan Wanbao
Directly cut out a small hole
The original sanding pieces that were originally intended to be polished are all fine sand. It is too wasteful to play this, and it is too lazy to get it.
In memory of my power that has been unable to oppress the suicide.
The original power supply has only one sata interface that can be used for modification.
The black line is the ground line. Yellow is 12v red is 5V.
Connect converters.
The blue line is used to power the external tank submersible pump and the cooling fan. 
Broken 12V into large 4D and then the original 5V reserved for later upgrade Blu-ray burner.
Basic completion (ideal completion, there are many pits behind)
Can't go in
Later, the tube on the graphics card changes the 90-degree turn. You can go in without damaging the water pipe. (not shot)
Then all installed, cold shot is also good with a line brake. The lines are all going well.
then. . . . Turn on the fan and turn it on. The pump is also draining. Cpu temperature is 12 degrees (tap water just poured in). Water tanks and submersible pumps are behind the cold exhaust.
then. . . . . Excitement began to burn. . . . Then the power was hung up. . . . The performance before hanging was when using everest to do system stability testing. Then the fan suddenly began to be violent, because the fan would not have changed when the temperature of the cpu was changed after the water cooled. It means pure meaning and turns to prove that he is still alive. The fan turned violent for about five minutes and the whole machine was powered off. Gen8 usually does not start when the power is orange power light, and now it is not lit, with no plug-in like.
Asked in the group. Everyone said that the power supply was burning. I said that if the power supply was burned, it would be directly powered off. Later I learned that HP's original power supply has temperature sensing that can be transmitted to the motherboard. Calculate the power consumption, because the former high temperature has been used for down-clocking, said that my 95W 1280 is 20W to 30W this state is running. With the graphics card 30W, motherboard and hard drive what is 30 (cpu) +30 (graphics) +30 (mainboard hard drive, etc.) is 90W so 140W original power no problem. Later, I changed the water, because the temperature was down and opened the test, it is estimated that the cpu directly up to 95W. Then 95 (cpu) +30 (graphics card) +5 (submersible pump) 10 (cpu circulation pump) +20 (graphics circulation pump) +28.8 (16 fans of 0.15A12V is 28.8W) +30 (mainboard hard disk, etc.) = 218.8w Then 150W power actually uses a standard 220W. . . . . He glows. . . Then he committed suicide. . . .
Then changed the 400W disassemble power supply downwind.
To change the graphics card 8P into a large 4D motherboard green line and any black line docking and then turn on the power supply on the pass
Then measure the graphics card 8P is not regular 4 12V
Four wires tied into one
Too many piles cannot fit in
Later, they were all tied up and tied up.
Later, when he was afraid to re-burn the power supply, he let him cycle for one night. He did not leak water and he did not restart.
Flat water can also
Three small tails. . .
Boot temperature 14 degrees
One hour after booting, the cpu temperature 21 to 22 degrees graphics card 52 to 53 degrees (only open a cfun and a QQ). 15 degrees at room temperature, cpu outlet temperature of 19.1 degrees
The video card was cratered, and it may be that it was coated too thick for about 1cm because the thin coating fell down for the first time. Later on the squats were painted more, and the result was that the thermal conductivity was too bad, or I didn't polish it, and the exchange rate itself was low. (The seller said that this thing was originally used by ddc, the exchange rate is not very good)
It's all over now, thinking about it. Should first cop open cover for liquid metal, and then only cpu water cooling. The graphics card is usually 50 degrees cold. Also. Then, the water cooling system can use external water source or built-in semiconductor cooling sheet (that is, the water pump radiator can be integrated in the gen8 chassis).
But better plan. Is for i5-7500 and 1050. One is the current power consumption is indeed very large, I gave the old man with i3-6100 configuration power consumption is only 50W Laozhang people usually play mahjong is 20W to 30W look like . One month and 720 hours a month without shutting down the power consumption of 30W per hour would also be 2.16 kWh without powering it on. And the i3-6100 uses the top 400 of the top 4 fans behind my fan like this one. Standby temperature is one or two degrees lower than room temperature.
Another question, I am stronger than i5 E3-1280 and i5-7500 than i5 it?
another. Two ssd arrays read 950M writes 750M (only one disk in a dual disk array)
Nas1 is n54l group of black group Hui 5 4T plus p610 array card.
Nas2 is a living room watching movie, 4T 2T group of 8T usually put Blu-ray and movies.
Another 32-inch and 27-inch match is really good
