The experience of the novice to the wingman - The choice of home ITX platform (Power and heat)

Will soon usher in the double 11, but recently all kinds of busy ah, but had previously agreed to finish this series before the double 11, and in order to prepare a number of players in the double 11 valued players, decided to stay up late to finish An article

Do not talk nonsense, first of all is one of the protagonists of this issue: Power

1.1 Power Supply Size

Remove the power that has already been eliminated and there is no conventional way to start, currently only available for DIY selection ATX and SFX power. The following will be a small player who won the first prize in the primary school students Mathematical Olympiad Competition according to the size of the standard size for everyone to calculate the size of the ATX power supply 150x140x86mm, a volume of about 1.8L; SFX power supply standard size of 125x100x63.5mm, a volume of about 0.8L In general The height and width of the power supply are the same (the side of the external power plug), and if the length of the power supply is slightly different from that of the standard size, the volume of the SFX power is less than half that of the ATX. Looking at the data is a bit far-fetched, let's take a look at it.

The figure above is a comparison of the size of the SRX and ATX power supply of the thief boat. This is very intuitive. Take the 15L mentioned in the previous article as the qualified ITX chassis size. If you use the ATX power supply, remove the internal board of the chassis at least. It took half a space to power

This is why even if the chassis supports ATX power supply, I also recommend the use of SFX power. As for the compatibility of the installation position, SFX power supply will usually come with an Adapter board. This will not worry about it and the rest of the space can be used to trace. If you have contacted a non-module, you will understand that for the side-transparent party, you can also choose to put it in your hands (the landlord is too poor to play with the side).

1.2 Power Interface

Having said the size of the power supply, the next step is the power interface. The interface here refers not to the end of the external plug, but to the end of the computer accessory. According to the pin number, the motherboard is generally 24pin (20+4), CPU8pin (4+4), and the graphics card is 8pin (6+2). ), there is SATA power supply In simple terms, the power interface is generally divided into full-module, half-module and non-module 3 kinds. As the name implies, the entire module is modularized and can be freely plugged and unplugged as required. The non-modules are quite unreasonable, and the combination of the two is a matter of giving you so many lines and half modules. The general motherboard and CPU are not part of the module (because it is necessary), and the graphics card and SATA power supply are left to the user to choose (as if it is very humane). The non-module black ones believe that everyone will see it and will not send it. Now, let's continue to look at the interface of the full module using the map of the ship.

Although the power of the half-module looks very practical, the evil is still there. For the perfectionist landlord, either to go to the end of the non-module black, or to complete the module is worth mentioning Yes, such as the landlord on the performance requirements of ITX powder is relatively low, in fact, as long as the motherboard and CPU power supply is enough, because there is no video card ah (said the new 1050TI do not need power supply ah) with M.2 interface SSD words Even SATA power supply is saved

In addition, if you choose to provide a full line of custom models to provide a custom line, in order to perfectly eliminate the black and thick but also side-bath party essential Oh ~ If it is the power supply comes with a flat wire group Oh, relatively thick It would be better to say that there is no need to buy customized lines for customized silicone, silver plating, etc., depending on individual needs. The landlord entered the silver plating, always feel that there is a mysterious addition

1.3 Power brand

Originally wanted to say that SFX power is only recommended by Yinxin, but afterwards, Yin Yin did not give me advertising fees, so at the same time, talk about another brand: Thieves ship thieves ship this year suddenly on the SFX power supply, quickly launched a series of Although the products are Great Wall OEM, but from the stability of the ATX power supply terminal for many years and the quality control of the pirate ship, it is still trustworthy, but the full module price is not cheaper than Yinxin.

Honestly, if you do not believe in thieves, or buy Yinxin bar 450W is not fully adequate enough to use the hyper-frequency band alone, before reflecting the high load screaming problem is also fixed in the 2.0 version, when you need to pay attention to the purchase oh

As for other brands, there is not a lot of word-of-mouth evaluation on SFX power supply. If you need to be cautious about pricing, we all say that a good power supply costs 1 watt per watt, but for SFX power supplies, the ratio may increase. To a block of 5 As for the gold medal certification, because I heard that many manufacturers have secretly shrunk after obtaining certification, so this will not have to care too much about it. After all, the difference between the power supply is enough for this electricity run for a long time, but the perfectionist landlord is sure Gold medal

1.4 Summary

Whether the chassis support does not support ATX power, select SFX power! Look at each person’s beliefs and choose Yin Yin or a pirate ship! No need to select the lowest power card like! 450W or so with a video card!

2.1 Classification of Heat Dissipation

According to the different heat dissipation media, it is mainly divided into air-cooled heat dissipation and water-cooled heat dissipation (think of liquid nitrogen.) Because of the small size of the ITX chassis, it often does not support water cooling, but the price of water-cooled chassis such as the Ncase M1 plus one-piece water cooling is not something that ordinary wire can withstand (such as the landlord). It is worth mentioning that According to actual measurement, the cooling effect of low-end water-cooling is not as good as that of mid-to-high-end air-cooling. Occasionally, such a devastating problem as water leakage (captain flutters on the street), so here's a detailed classification of water-cooling is skipped here... If the landlord wins the lottery If you do, it will fill in

Air-cooled heat dissipation is divided into side-blowing and under-pressure heat dissipation according to the direction of the wind, and the characteristics of the two are different because of different wind directions. The wind direction of the side blowing is parallel to the motherboard. According to the installation direction, the heat of the chassis can be effectively discharged or cold air can be sucked in. The wind direction of the downward pressure is perpendicular to the main board, which can effectively reduce the overall temperature of the main board including the CPU ( There are also cults that use the fan direction to switch.) The side blowing wind direction directly leads to the overall height of the radiator is significantly higher than the down pressure, running up 80mm, such as the famous silk artifact anti-human 400 has 159mm

Because of the compactness of the ITX chassis, there is a strict requirement on the heat dissipation level, and basically no side blowing. Therefore, the next combination of the recommended chassis, to recommend for everyone to recommend the appropriate pressure-type cooling

2.2 Heat Dissipation Brand

Before you say the specific model, first share with you a little more about the landlord's relatively good under pressure heat brand, after all, the back of the recommended heat dissipation is basically out of here

Noctua is a brand from Austria. The representative of silence is to say that the only drawback is that it is too expensive.

Thermalright comes from the brand of Baodao, and the representative of efficient cooling is also very expensive

Silver Stone also comes from the brand of Baodao. It is famous for its excellent chassis design and SFX power supply. Its heat dissipation is also outstanding.

There are also some brands that are not particularly famous, but have excellent performance in terms of cost performance

INTEL original heat this will not need to say it Looks like a Delta OEM oh ~ But on the difference between boxed and bulk, in terms of the original heat does not really advantage

Although ID COOLING is an English name, it is a domestic brand. Regardless of this point, its rich product line and the price of close to the people really make this brand fire up.

Jonsbo (Jonsbo) is known as the "Luo Sibo", the all-aluminum side of the chassis is popular in the DIY industry. In recent years, the heat radiator products have been introduced. It is worth mentioning if you look at the parameters and prices, regardless of the actual performance.

There are also some brands that have good external reputation but do not have regular channels at home, such as Scythe . The landlord also remembered ABEE

2.3 The choice of heat dissipation

According to the overall height of the radiator, there are generally several watersheds:

1 limit height (below 40mm)

    In this height range, the owl L9I rides

The height of the owls are basically compatible with most of the chassis, the performance is not inferior, but the price has always been very touching ... ... but Baidu looks like there is an order minus 40 activities, are interested can look at

But what surprised me was that I uncovered that there was an HP400 that was 1mm shorter than the N9I.

Although the cooling effect is generally reflected, the price less than 100 is indeed very competitive.

At the same time Yin Yin also has a 37mm, so with the silkworm and owl formed a 100 series of arithmetic progression.

As for those fans that are designed to compress the heat sink volume, the height can even be compressed to less than 30mm, but the effect is... So if it is not the ultimate requirement, it is not recommended to buy such as this (it is not really black)

   However, in the previous article, we did not have a chassis of the ultimate size. With the principle of best use, we jumped directly to the next level.

2 normal height (40~60mm)

This is a common range of heat dissipation in ITX chassis, and INTEL's original heat dissipation is also included in this list. However, the official did not give the size, but from the wide width of 51mm just wide enough to plug the original heat, it should be around 51mm (estimate the width of the design is also out of this design) and ID COOLING even in this range There are three products in the layout, and the model is also the three leopards IS40/50/60. The heights of the IS50 and IS60 are the same. It is also the principle of best use. I would like to add more money on a heat pipe. IS60 (the landlord is really not a card bar)

In addition, there is a PRO version and a soaking version on the basis of IS40, but according to the reflection effect and IS40 is not much difference, so it is not recommended

In contrast, Yin Xin's product line layout is very reasonable, and the gap has been appropriately opened. And AR06 is perfectly compatible with the small crow RVZ02's ​​58mm height limit (as Yin Xin powder landlord must be included)

The landlord's cabinet is placed on the desktop, and there is no noise in daily use. Now about 20 degrees at room temperature, standby is about 30 degrees. The full load temperature is more than 60 degrees, but at this time, there will be slight noise in the night.

As high as the AR06 is the AXP-100, which is a king of heat dissipation. If it isn’t Yinxin’s faith, I’m into it.

3 high height (60~80mm)

   This height is basically the limit of heat dissipation under pressure, and further upwards is the side blowing.

The owl is still the most important, the effect is still outstanding, the price is still touching

The king of heat dissipation is not to be outdone

Under the pressure of the giants of the owl and the Limins, Reese Boley pushed an HP 625 attempt to get a share from the high-end market. 168 also brought light pollution, and I have to say that Reese is really the gospel.

2.4 Summary

The recommended heat dissipation here is basically over. In order to facilitate comparison, we have made a matching table, we can refer to the chassis are recommended in the previous one, according to the thermal limit order; heat is recommended in this article , sort by height, sort by price, same height

Basically, under the same workmanship, the heat sink with the same number of heat pipes has a higher heat dissipation effect. Therefore, it is recommended that the conditional value friend refer to the above table to select the maximum heat dissipation. As for anyone who cares about nickel plating, mirrors, or heat, I just want to say: Actually, there are no birds that use a few degrees and they will not blow up.

PS: Remind by friends, a Gabriel leaked 60mm, here reissue

Finally say, in fact, this heat does not matter this thing is not so important, the daily home use original heat dissipation is actually sufficient, but the landlord obsessive-compulsive disorder must be on a best heat dissipation before the chassis toss for a long time everyone is still the right to do it ~ In addition, some There may be stalls in the heatsink and motherboard, so it's best to check before you buy.

So here, this series is over and the task before the double 11 is completed. I am not a big god. I am just an ordinary lover who loves tossing love. Sending this series is the first to leave an imprint on the road to his own opportunity. He also hopes to give some help to newcomers who are just starting to take the opportunity.

If there are mistakes, please also ask the great gods to criticize and correct me.

Afterwards: Given that a lot of valued friends requested to send a HD picture of the queen of the cover, the end of the last article will satisfy everyone.
