Help with loud pop and case fan failure!

I had accidentally broken some wire that one of my case fans had and I decided to solder them back together and make the quick fix. Once I finished soldering, I tried to re-connect the fan (via molex connector) but was not pleased to find that the fan didn't work...even with the new solder fix. So I was just simply about to pull out the connection when I heard a loud POP and then all of my working fans went out. The led's on them still worked and could still be turned on or off by using the included fan controller knob on the front of my case (CM sniper). So my question is, is there some kind of fuse that could have popped or something? Does anybody have any suggestions on fixing this problem?

There's no such thing as a "fuse" on the inside of your computer, at least not in the traditional sense. A pop usually means the power supply blew out, although in this particular instance, since there was a known wiring issue, it's more likely some kind of short ... the effects could be contained to that one component, or could be worse than that.

Does the rest of the system work at all? It sort of sounds like it, but can't be sure from your message. If so, you may have gotten lucky and just blew out the fan and/or the fan controller. First thing I'd do is disconnect all the fans, take a different fan and hook it up directly to the motherboard, and see if it works. If it does, it's likely you just fried the controller; easy to fix. If it doesn't, it may have had more far-reaching effects to the power supply or motherboard.

I generally don't like to mess with soldering small wires like that. It's not exact, and far from guaranteed that it will work out right.

Yeah I figured there wasn't any such "fuse." I was just making sure. The rest of the system works flawlessly, actually. I'm using it as I'm writing this. I'm about 99% sure it was the fan controller that blew out because when I heard the sound, it sounded like it came from the front of the case right where my fan controller and all is (hence the reason I looked straight at it right as I heard the pop). The fans all work (except for the soldered on, of coarse) because I tested them each individually on a motherboard header.

Where do you think I could get a replacement fan controller that is identical to the one Cooler Master included with the case?

Do you think Cooler Master would provide me with this specific part??

Thanks DogSnake! I'll do that. Do you think it would be more useful to contact them via telephone or just through internet (like email or something)?

just had the same thing happen to me but a bit wierder.....opened the case door while the pc was running to take a qick picture of the parts and i heard the loud pop and all the fans exept the one for my watercooled CPU just went dead(lights still works tho)...in writing moment i have connected all 3 fans(door front and top) to a molex each...managed to unhinge the top of the case to take a look at the fan control circuit board and it smells burnt

and my computer havent even passed 2 weeks old....seems to me like Cooler Master havent done their Homework when it comes to fan controller cicuit boards


gonna write an email to the shop i bought the comp( i chose the parts they put it together) and ask them to send me another circuit board as the current one is broken
