The fan on the auxiliary power supply is quite large, so I'm going to modify it so it fits inside the case. First, the original fan is way too big to fit, so I went to Hard Off and bought a slightly smaller fan\u2014or rather, one that came with a heat sink and a vacuum unit. Judging by the looks of it, the performance seems about the same.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I want to mount the fan on the front side of the PC chassis, so I'm making it external. Then, I cut away aggressively at the power supply casing wherever it was interfering, making it a much slimmer power supply.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After removing parts and bending the metal, I successfully made it slim.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I tried placing the power supply neatly right here at the front with the power supply fan positioned as shown, but when I drew power from the power supply's fan connector, it would spin at maximum RPM right from startup and was really loud. I probably should have routed a fan control signal into the power supply from somewhere, but even after probing around with a tester, I couldn't figure out which signal was for fan control.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Right where I wanted to place this fan, there was already a connector coming from the main unit's CPU cooler, so I decided to tap into that by splitting the connection.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Thinking Handsman might have what I need, I went there and found a nice little universal PCB, so I bought that and gave it a try. I think I was able to neatly solder and split the connection.<\/p>\n\n\n\n

Now, just like the main unit's fan, it can speed up or slow down depending on the load. That said, when playing Monster Hunter as a game machine, it constantly runs at high speed anyway, so maybe it's not super meaningful, but I think it's nice that the fan gets quiet if you accidentally fall asleep with it left running.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Next is the 8-pin connector for supplying power to the graphics card. Initially, I just hooked up 12V and ground using a 6-pin\/8-pin connector I happened to find at Hard Off, but this time I tried making it look clean with heat shrink tubing. It would be better if I could attach the connector a bit more neatly, but I don't have one right now, so please forgive this version. I might reinforce it with UV resin later.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Next is the AC 100V power input. The original PC has a service outlet, so I could use that, but to keep the appearance clean and wire it internally, I'm going to cut the power cord and solder it.<\/p>\n\n\n\n

By the way, to turn on an ATX power supply, you usually drop the power-on signal to ground, but this Fujitsu PC's power supply has a slightly advanced specification where the AC power to the service outlet also turns on whenever the motherboard's power turns on. Because of this, I didn't need to control the power-on signal for the auxiliary power supply and just wired it directly to the ground line.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Since it's an AC power supply, as long as you don't mix up the ground, it should be fine, but just in case anything happens, I marked the left and right sides with a pen so I don't mix them up.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I soldered it to the AC power service outlet. This is connected to the AC cable, and when the power turns on, the AC 100V here turns on as well.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The wiring looks much cleaner now.<\/p>\n","protected":false},"excerpt":{"rendered":"
