I am not a fanatic factor. Therefore, for my own home computer, I only need to use enough. Of course, my selfishness is still there. Although I do not play large games, I can improve my computer's performance. The mainframe has been placed under the desk all the time. There are closed desk legs on the right side of the desk. Therefore, the air circulation is relatively normal. In addition, the dry dust in our northern house is large. So recently, even if we watch a video, the host fans will Speed ​​up the speed, mainly CPU fan cooling is not enough, you know, I still use the CPU comes with the pressure fan.
In order to reduce noise and cooling, replacing the CPU fan is on the agenda. The impression that I wanted to put water on the water at once was always high, but considering the price, risk, and noise considerations, I would like to see that some pumps are more like fans than I would like to see if there is no space in the chassis. At most install a 120 cold row of CPU heat sink, or give up, return to the traditional cooling fan. After some exploration on the Internet, cat fans are more recommended. Indeed, fans of ordinary users are already very good fans, and the price is not lower than that of low-end water cooling. In view of heat dissipation and noise, the last decision was made on a cat fan. Let me talk about the case of my chassis. My computer host originally bought the brand machine. It was the HP HDX 913cn that was purchased in 2008. At that time, this host was a machine designed for games, and the host and the monitor were sold separately. From a current point of view, this machine case belongs to the size of the tower, although the hardware inside allows me to replace it again three years ago, but this case has been retained, in general, the material used in this case is still relatively thick , with three 5.25 optical drives and four 3.5-inch hard disk drives, and two special slots, one of which is occupied by the HP mobile hard drive slot.
Taking into account the heat problem, this time to buy a tower radiator, in order to prevent the installation, I deliberately measured the internal width with a ruler, to determine the data after the start of selection, cat fan D series is too large and certainly not fit, after several comparisons, The 120mm cooling fan with the NH-U12S cooling fan and NF-S12A was selected. The S12A was not installed on the U12S, but was installed on the back of the host to replace the old back-side fan. After the order is confirmed, it will be handed in 3 days and the installation will begin.

Owl (NOCTUA) NF-S12A PWM 12cm fan (4-pin intelligent temperature control / CPU fan) 160 yuan Jingdong direct link After the arrival of the hand feels really heavy, the box is not imagined big, first talk about U12S. The brown color of the cat's fan, as always, is very rigorous. It looks like a big factory. After opening, the accessory box with the contents reminder is used, and the fan radiator body is taken after the removal. Let's talk about fittings and accessories. There are three installation instructions for three different platforms. The installation tools, heat-dissipation silicone, and fan hooks and deceleration lines for the other fan are all available. Taking out the fan's body is bigger than I thought. I'm afraid I can't fit it in, probably it should be no problem. The fan is also equipped with a 12mm 1500 rpm F12, with 7 trapezoidal blades, which are designed with emphasis on the air pressure. The bearing is the latest SSO2 (self-stabilized oil pressure bearing), and the stator guide vanes with slots on the back of the fan can be used. Play a role in reducing wind noise. The heat sink body has 5 6mm heat pipes and 57 heat sink fins; the overall appearance of nickel plating improves the texture and strengthens the anti-oxidation. From the top, Noctua full wire radiator products are still used for reflow soldering combined with heat pipes and fins, fins The saw-tooth design on the edge of the sheet can reduce the wind noise, and the leak-proof wind diversion design is adopted on both sides. The heat sink is polished and the lines are delicate. Because the heat sink has a thin body design, it has no effect on the memory.
Look at another cooling fan S-12A. The packaging box adopts a transparent window to open the front cover to see the design of the physical body. The S-12A and the F12 with the radiator do not look very different, so we will not go into detail here.
Because it is the old chassis, unlike the current chassis is open on both sides, so the installation of the heat sink base needs to remove the motherboard to install the buckle back, the installation process is not shown, in short, all the cards are only removed for installation Buckle back plate. According to the instructions after installation, this small installation space in my chassis also feel that the goods are really not small. My chassis has an overhead fan in addition to the CPU fan and chassis rear fan. After winning the original chassis fan, found that the S-12A is not on the original screw eyes of the chassis, and later found that the original chassis fan has a grinding tool, remove the new fan installed after the perfect installation, in addition to not match the color Everything is fine. As far as the colors are concerned, no one can see the cover.
But the problem lies in the chassis cover, after all the installation, found that the chassis cover is not on, carefully looked at the chassis cover, the original chassis cover in order to install the chassis card lock mechanism, a large piece of convex inside the chassis cover, this is my Unexpectedly, I always measured the vertical distance but ignored the protrusions on the inside of the chassis cover, resulting in the lid being covered with a protruding part that just caught the radiator head and the tip of the heat pipe. This will not happen. What should we do? First start with the radiator, the height can not be reduced, remove it and turn a 90 degrees in the installation, unplug the bottom of the screw position, but unfortunately only from the chassis cover to find a solution, and finally reluctantly part of the raised iron sheet cut off, waste Even though the radiator can still touch the lid of the chassis, it can be a good idea to cover the lid.
The overall speed of the radiator fan is not high, so the fan noise is not large, and the fan noise source in the chassis is the video card fan. As for the cooling capacity, because we haven't gotten hot in the north yet, we can reduce the three or four degrees from the previous tests. As for noise, there will certainly be sound at full speed, but there is no quagmire of vibration noise brought about by the high-speed operation of the fan. This is just wind noise.
As a Virgo for perfection, how can we tolerate such a chassis? Well, for the chassis, it will be more convenient to upgrade the system later. Ever since then, they have started various sea elections. Originally they wanted to select a full-tower chassis, such as Cool Mother's tank soldiers or a thief ship's 780T. However, a ruler is too big, and the table below it cannot be installed. Various types of light pollution are popular, but the effect of the acrylic plate is not very good. Moreover, I rarely turn on the lights. I have already had a blue atmosphere lamp in the old chassis before, and I have barely opened it.
There must be a semblance of shape for the appearance of the model. The words Virgo are so difficult to wait for, so tangled. Afterwards, he saw the MasterCase Maker 5t chassis in good condition, especially on both sides of the tempered glass side. The official price of the 1699 was higher than that of the tanker who had chosen only to sell 999. . Tangled for a long time or finally fell down in the MasterCase Maker 5t chassis (hereinafter referred to as MM5t) under the garnet skirt, placing orders.
Cooler Master MasterCase Maker 5t Modular Tower Chassis (Supports ATX Motherboard / Red & Black Dual Color Design / Magnetic Suction Panel) 1699 yuan Jingdong direct link After a few days, the express delivery arrived. It was really a big guy under the outer package. Fortunately, the elevator in the house, he took it back. Open the outside of the logistics box, which is a regular box, writing the production date is February 17 or relatively new. After opening the package, the thick black shockproof foam is seen. There is also an iron box on it. Open it to see the original box, the screws inside are classified and sealed. The bottom of the box is a foam coating with a fleece texture. In addition, the box actually has a magnet suction that can be absorbed on the iron plate. Take out the chassis body, not to be scared, after all, just a mid-turret chassis, and in addition to a width wider than my previous chassis, height and length are similar. I didn't have heavy weight on my previous chassis.
After packing, 18.8 kg is packaged
MM5t has many cover plates that can be disassembled, and they all rely on magnetic adsorption, which is very convenient. The vertical handle at the top is also one of the reasons why I chose MM5t without choosing the cheaper MM5. First talk about the front jack, the chassis with four USB3.0 jacks, but my old Z77 motherboard only has a USB 3.0 slot, so in fact only two jacks so. On both sides are the light control button and the fan control button. The light has three modes of long light, breath and close. The fan can only control the high and low speed two gears. It is recommended to change it into a potentiometer-like stepless adjustable current gear. Less. After opening the front cover, there is a front side panel with a mesh inside, there are two 140mm fans, there are two 5.35-inch optical drive panel above the removable, if you do not install the optical drive can also install a set of 5.35-inch fan. There is only a two-bay 3.5-inch hard disk tray inside the chassis, and two SSD mounting positions. This mounting position is too far from the 3.5-bay, even if the tray can be moved forward. In addition, the chassis is equipped with a graphics card holder. There is also a 140mm fan on the back of the chassis. There is no standard fan at the top of the chassis, only the mounting position. The whole chassis adopts the power supply design, back wiring, and a dedicated LED light fan control box on the back of the chassis. The device is powered by SATA cables. The fan is a 3pin plug and can support 6 groups. The LED light interface can support 4 groups because I Light pollution is not a cold, so it is not intended to increase the installation of lights. There is a filter at the bottom of the power installation section. The cover and handle at the top of the chassis can be removed.
The following began to move, the original computer boards were removed one by one, and then installed into the new chassis. The original newly installed S12A fan was mounted on the top of the chassis as an intake fan. The overall situation of this chassis is very good, but it is a lot of trouble on the wiring, which makes me have a lot of trouble in the installed capacity, I originally used Zhenhua Kingdee 550 power supply, its module power cord does not match this chassis The installation location is mainly due to the fact that the distance between the optical drive, hard disk, and SSD is relatively long and requires two SATA power cables to be connected. In addition, the rear control box also needs a SATA plug, which sometimes seems to be stretched. The top fan's cable is very short and can't be connected to the control box. Finally, it can only be connected to the motherboard. In addition, I don't dislike the SATA socket of the original ASUS motherboard. Finally, that graphics card holder, I may not have used this high-end gadget, the original installation location, the bending angle of the metal cylinder and the graphics card conflict, but unfortunately I removed the cylinder will change the direction, but the support seat will interfere with the graphics card The fan, in short, didn't feel much better. Maybe I didn't play right.
Ebara mainframe with equipment total weight 22.6 kg
The new chassis is fully loaded with 21.9 kilograms
After installation, the overall system is very clean, with no extra bumps. The black glass on both sides is blackened and the built-in red light tube looks particularly good. In addition, the interface of the front panel has a backlight, which is really good. Because the interior space is spacious and there are many fans, it is still very obvious that the temperature has fallen drastically, at least by 7 or 8 degrees. Of course, there is a small problem that the front cover has noises on the fan noise, and the noise on the front cover is smaller, but it is not beautiful enough.
Because a heatsink was finally triggered to change the entire chassis, suddenly 2K Ocean went out, and it was really not as good as the entire water-cooling, but considering the hardware upgrade in the future, the chassis can be used to comfort. Yourself.
