Cooling: Is this a potential fire hazard? [Images]

[1988mgrimes]

I am making a computer for my studies inside an old PS1 case. I have decided on having six fans to cool it; three intake and three exhaust. The fans are small 5v ~ 0.9W 30mm x 30mm x 6mm Sunon brand laptop fans (the fans are getting 5v from a molex adapter). I had an abundance of old 3pin to 2x3pin cables lying around, so I daisy chained them together to form this wonderful contraption:

















My questions are (keep in mind the final product will be in a case):
Can this cause a fire?
Would this be safe for extended use?
Would using electrical tape help to insulate any parts to stop a fire?
Should I not daisy chain it but instead buy a new 3pin adapter that has 6x male 3pins?

Everything is just splitting off, no difference between that or a 1x6 splitter really. I would at least wrap the connectors in tap so no chance the exposed pins can contact anything.

Ok. Thanks, I'll wrap them in some electrical tape to stop exposure. In the rare event of an overvoltage I want to be safe from a fire (as does anyone really).

From taht thread there, the 5v line has 11amp, or 55w or power available (A=WxV, so W=A/V). You have 0.9w fans so you could run about 16 fans before the Molex would be at it's rated spec. You have 6, so almost 2/3 less, so you should be fine.

Nice. I might order four or so more fans then for some better airflow, and maybe a better 3pin splitter.

Thanks for your help.
