I have to say that when I was too young, I entered the pit of the Lianyu Q02. Now it has become an old driver. After seeing a lot of knowledge, even though this kind of ITX chassis structure is spurned, because this Lian Li PC-Q02 is how to say that Ah Cai is meticulously matched with the color, it still can not bear to discard.
From the sequence of the fuselage, this is my family's No. 3 ITX machine, ITX No. 1 and No. 2 machines have been completely abandoned by a component I have left, but also the Queen's exclusive No. 1 machine. However, the written sequence became No. 7 because it was very early in service. It had been in service at home for 14 years and Ah Choi had only started publishing the text in Zhang Ama's codewords until 16 years ago.
LIANLI Lianli PC-Q02E Royal Blue MINI all-aluminum ITX chassis 479 yuan in addition to small size, unique color Q Meng, exquisite workmanship, no other advantages, this can support the size of the single slot alone did not support significant independence expansion slot, power supply Location design tricks, power supply fan and CPU fan grab wind, front USB 3.0 cable too hard. Jingdong direct link I did not know when I approved the improper oar paddle, the power supply cover the design of CPU heat chicken structure, do not know whether it was the first launch of the joint force, but it was the first time I learned in the joint force, in short, is 2 words - Hot chicken!
The official wind road is as shown above: but it only installed the power, did not install the motherboard. In fact, because the chassis design only supports the CPU cooling and SFX power supply, the air duct is actually facing the fan.
At the beginning, I gave this radiator a hand-made person named G large direct power supply and Limin Fengling TS 90M radiator.
Limin Xiaofengling TRUE Spirit TS90M 4 heat pipe CPU heat sink 189 Yuan Li Min Feng Ling True Spirt 90M is 135mm 9225 side blow tower radiator in the best cost-effective representative. Jingdong direct link 
However, this non-mainstream power architecture always requires a 220V to AC 12V notebook power adapter. Moreover, due to the safety regulations of single-wire 20A current limit, the maximum power is only 240 watts, although there are hand-work products to transform the capacitance to 300 watts, but I believe I do not have 3C and safety regulations with absolutely no reassuring.
Later it tossed into a combination of the ID-Cooling IS60 press cooling + Yinxin SX500-LG gold full module power supply, this heat dissipation is the only maximum heat dissipation (6 heat pipe) scale in the case of official design and installation of SFX power supply s Choice. The reason is that the thermal limit of Lianli PC-Q02 is 60mm high, that is to say, Limin AXP-100/AXP-200 (62.7mm), Owl NH-C14, and Hercules PH-TC12LS (75mm) are all extremely high. The conflict with the Q02 chassis of the SFX power supply.
However, this heat dissipation and power supply configuration constitutes the worst case of heat dissipation. So this chassis long-term standby temperature 50+. As shown in the figure below, the cross section of the CPU fan is completely blocked by the SFX power supply.
The negative pressure at the inlet of the two fans is equal to that of the fan. My God, this must be the designer of the CPU cooling more careless to make such a big design, it may be coupled with the designers have never seen the TDP more than 80 watts of CPU. The only solution is to replace the CPU fan, but the thermal performance of the anti-loading fan itself must increase the full load temperature by more than 5 degrees.
According to the design of the Lianli PC-Q02 chassis, this CPU has a poor chassis design with a 60mm ceiling. Although "inspired" countless, but every year a new Qiao Sibo, U1 chassis structure is better than it, and the latest U1 PLUS has indeed been considered Dacheng.
Now look at this Made in Taiwan's joint force Q02 with only black and Acacia left to show off 80 points of workmanship.
A Choi once wanted an impulse to sell it with salted fish, but ... frustrated is that the price of 499 is more than 30 yuan more than the original price, and the salted fish is sold for 3 months (in fact, it is a chassis that has never sold sincere Q, I don't sell with a dragon knife!) Nobody bought me.
Wrath, I will change it and continue to use it! The first step is to change the power supply and replace it with a power supply that meets safety regulations and is small enough. The FLEX 1U power supply is a good choice. But - most of the 4015 fans of the FLEX 1U power supply can be noisy. Until Ah Cai visited the C Forum to see the installation of the post when it encountered this: Haiyun SSP-300SUG. Full module, 80PLUS gold, standard FLEX 1U
Haiyun SSP-300SUG_ Taobao search Taobao search is the most intelligent product search engine, through the operation of big data, accurate understanding of goods and users, to provide accurate personalized search experience. Direct links to s.taobao.com Do not look at it and expensive to buy less channels, but Ah Choi waiting for it for many years. First of all, it is a standard FLEX power supply. The standard FLEX size should be around 150mm x 80mm x 40mm. The YH 1U power supply and Haiyun SS-300M1U with a power of 350W were found to have a size of 190mm x 81.5mm x 40.5mm.
This 4cm will not be installed into the joint force Q02 chassis - installation mode see the following figure:
The universal nylon cable tie Dafa bundles Rhyme 1U power supply on a 3.5-inch 2.5-inch drive bay.
Don't laugh, this is the only way to break through the original design of the chassis. After all, I don't have machine tools and CNCs to cut metal parts.
I have to change the chassis has a principle is in addition to the last resort hole, basically do not destroy any of the chassis structure and panels. Therefore, the AC power lead of the power supply must use a homemade extension cable, a 1.5 square power cable, and heat insulation of the heat-shrinkable tube.
The power supply is installed with the 3.5-inch bracket buckle originally designed for the chassis.
The power supply and driver are already in place.
This is so firm that you don't have to worry about the power source moving into the motherboard and the heat sink.
After retrofitting the power supply, optional heat dissipation includes the 9255 side blow-tower type, and the 12025 lower-pressure heat sink can be perfectly installed. No longer worry about the original power and heat dissipation structure of the Lianli PC-Q02's original chicken lead to the use of the i5 ribbon. The high temperature performance of high-performance CPUs above K/i7/E3 is a problem.
In fact, as the only one who uses the best BIS (Best in Slot) selection principle, Ah Cai has tested the Geminll M5 T520, Owl U9S, and ID-Cooling IS-60 three radiators Contrast, the test process in order to make as much as possible to make gold coins, I will write a separate press-type thermal test Zhang Aunt original list of small Aunt Xiaobian me.
Here directly to the results - I finally chose Cooler Master Geminll M5 T520 as the final configuration.
CoolerMaster (CoolerMaster) Blizzard T520 radiator CPU cooler (multi-platform / 5 heat pipe / heat pipe direct contact / with grease) 159 yuan 150 price of the most powerful under pressure radiator, fan mute, E3 / i7 full load below 70 degrees . Jingdong direct link Here also have to mention the compatibility of the ITX motherboard installation - because the IS-60 radiator is the pursuit of high chassis compatibility, the height is very low, only 54mm.
So it can only be installed in one direction, that is, the direction of the heat pipe toward the IO baffle. If it is installed horizontally, the memory vest will push up the radiator.
Into the cool Geminll M5 T520, height increased to 63mm. Of course, in accordance with the original design of the joint force Q02 heat dissipation limit 60mm, this height is completely installed, will conflict with the SFX power supply. It really takes care of the memory and can't take care of the power.
The advantage is that the entire heat sink fins can cross the vest memory. Can be installed in two directions, horizontal and vertical.
Finally, the fit is completed. The ITX chassis is extremely difficult to install as usual. The process is cumbersome and complex, and even accidentally breaking a pin on the front USB 3.0 interface of the motherboard leads to only one of the front two U3 ports. what.
The heat dissipation is easy to install. At present, I only accept air-conditioning, owls, and chasers. All of their pressure and tower heat dissipation are unified standard fasteners. They can be loaded with fasteners and pre-installed into the chassis to connect the cables. Then install heat.
Both the ID-Cooling IS-60 and the cool T520 need to be installed on the mainboard of the cooling system, and the CPU power supply line should be connected at the same time. Then the mainboard is installed in the chassis. ITX chassis installation difficulty increased by 50%, bad review!
The original aluminum foot pad of Lian Q02 chassis is very small, the most important thing is not to slip! Do not slip! Do not slip! The consequence of not being slippery is that plugging in a front USB can push the entire chassis away. I replaced the aluminum alloy CNC amplifier chassis pads bought by Taobao with a rubber slip ring.
The 9205 mining and melting blue fan in the following figure is the chassis exhaust fan. This is also a must for long-term high-load working chassis. Otherwise, the heat of heat dissipation will not accumulate in the chassis, causing the CPU temperature to rise above 50 degrees.
This position can be seen after I modified the original design of the chassis power wiring, through the three AC extension cable to the tail of the chassis SFX voltage bit baffle, this baffle is also the finished product of Taobao, you can search for PPLANE, this store is my city The hometown, bizarre metal power baffle a lot.

Chrysanthemum looks like the picture.
The actual test of the power supply and cooling remodeling is a very successful drop. The first satisfying factor is silence, although it isn't completely silent like fanless cooling, but there is only a little weak ball bearing noise.
The second purpose of meeting my second goal is to achieve a rapid improvement in the standby and full-load temperature of Lianli PC-Q02 chassis. From the original standby of 50 degrees to 35 degrees standby, full loader from 90 degrees to 72 degrees. Do not look at this temperature is only the normal level of the ATX chassis, in fact for an 8L and still fully silent ITX chassis, I have been very satisfied. The important thing is that there is no harm without comparison - the temperature of the copying machine can be seen at a glance - the green line is the ID-Cooling IS-60, the yellow line is the owl U9S, and the brown line is the cool and cool T520
Satisfying my third purpose is noisy. As a home Internet access, quiet is good! Dell aliens Alpha 2 and Intel, along with my previous installation of the wide Chopin chassis 2 ~ 4L smaller, but because CPU heatsinks use ultra-thin heat / high-speed turbo fan, they work very fan noisy! This is a deadlock that can't be solved. Only when the volume of the chassis is enlarged to about 8L, can it accommodate the large-sized CPU heatsinks such as the owl U9S or the cool-cooled T520, so as to be relatively quiet in working condition.
This noise is basically the volume of the ambient background noise, of course, the ear can hear a little bit of the sound of the three fan ball bearings in the chassis.
A picture of the last one, which announces the originality of new and new players -
The 8L "small" chassis yelled at 32-inch "big" monitors -- the AOC Q3277 32-inch AMVA 10bit 2K monitor, Jingdong Special 2149 to start unpacking.
There are also by-products of this thermal transformation -
