GK3V & Others -- Fan Behavior EXPLAINED

[pixelkiller]

Is anyone else having a problem with the fan staying on even after shutdown? I bought this fan set it all up and i dont think i can keep it like this. I have tried chaning the USB behaviour in the advanced power settings, tried turning off fast boot. Neither worked at all. In the device manager ive also set it to allow the PC to power down the usb if it needs to.

This situation is useless. Due to the shutdown mechanism, the hardware and software of the machine will stop working. Therefore, the fan function will also stop.

pixelkiller has the fan connected to the USB port. My AK3 does the same thing. When I shut it down, the USB ports remain powered. The only way I could safely remove a USB external hard drive that was still connected after shutdown was to unplug the unit from the power.

Here's a link to a 5v 120mm fan that plugs into the USB port if anybody is searching. This one comes with grills even. 120mm Fan 5V USB Cooling Fan

Just wanted to show some results with a GK2 (j4125/8gig/128ssd) using THIS 5v USB FAN that I linked to in the last post. I ran some tests with Cinebench and HWMonitor. As you can see, my idle temp reduced to 38c, earlier, I saw it go as low as 35c, and while running Cinebench, I peaked at 66c. These are much much better results then I got when I did the same tests on a Terryza with no other cooling but a laptop pad. Not to mention the fan just looks cool as well.

I am using a similar fan placed underneath the case so that it 'pushes' air through the bottom grid.
I am having excellent results: temperature stays low (in range 50-60°C) during normal office activity (web browsing, filec copying, etc)

The only problem is that the USB port of the AK3 (I attached it to the port between HDMI and power cord) is ALWAYS POWERED even when system is shutdown. Any configuration workaround to this?

I don't wanna put a mini switch in bewtween....

coolmo,

Unfortunately, the only options are a USB switch or unplugging the unit.

As an alternative, there are present 5V output on the main board:
