Hi everyone. First post here, although I've lurked these forums in the past with questions.
First, the story:
So I've had a Qosmio x505 for a few years now, and it has for the most part served me well. Recently, the CPU cooling fan died. I ordered a replacement part, and swapped it out. Unfortunately, the replacement didn't work. It seems like the motherboard itself is the problem. I've been looking at an alternate solution for a while now. First I considered finding an available output on the power supply, but since it's a laptop it doesn't really have any available. I really don't want to replace the motherboard, and I can't afford to get a new computer for a month or two, so I'm considering making/buying a USB to 3 pin molex adapter.
Something like this: http://www.moddiy.com/products/USB-to-Fan-3%252dPin%7B47%7D4%252dPin-Converter-Cable-%28100cm%29.html
There is some free space in the laptop to place the cables by the fan, so it should be as easy as drilling a small hole in the side of the laptop case. I know this has been asked here before, but my primary concern is that I don't want to start a fire. Although I'm pretty comfortable changing out parts and doing routine computer maintenance, but I'm not really too comfortable with creating my own electrical connections. If the laptop is bricked, whatever, I'll buy a new one in a month or two, but safety issues are a big deal. Anyways, USB puts out .5 amps and 5 volts, and I have both my old fan and the replacement I purchased. Both draw 5 volts. The old one draws .5 amps, and the new one draws .4 amps.
I don't have a link to the new one atm, but here's the specs on the old one: http://www.pchub.com/uph/laptop/88-81229-21553/ADDA-AB7005HX-CD3-Cooling-Fan-.html#
I have no ideas about the wattage. but I figure since the USB and fan both drew power from the motherboard directly, it should equalize without any safety concern, but I just wanted to check. If this checks out I can order that adapter or just make one myself(or ask an electrician family member 😀 ) So does this plan check out, or have I overlooked something?
