Big Typhoon not spinning....

[Lynch Hung]

I have no idea why but sometimes when I power up my PC my big typhoon wont start spinning - i have to give the fan a little push so it starts going...how can i fix this?

Also...
Sometimes when I boot up my pc, the motheboard makes a single beep sound and nothing happens. I usually have to turn off the computer & switch off the PSU and then start it up again to make it work...Any ideas?

What is your mobo and PSU? Is the power connector to the mobo a 20 pin or 24?

Mobo = DFI LanParty UT nF4 SLU-DR Expert

PSU = SilverStone Zues 650W

24 Pin.

Take the fan part off, and look on the front and back..you should see a sticker. Carefully take the sticker off, removing as little bit of stickyness as you can. Then you should see a little hole with a nylon washer inside. Squirt a small bit of bearing lubricant in there (WD-40 will work too), and then wipe the surface as clean as you can. Use a little bit of rubbing alcohol to clean it so the sticker will stick, but don't get any in the hole.

Replace sticker. If the sticker doesn't want to stick, then just wait a while for the surface to evaporate, then clean it again, and cut out a little piece of ducttape.

Should be good as new. I had an old hard drive cooler, and it was so bad that you had to push hard with your finger to turn the blades. I did the above ^^ and it worked really good, moves a lot of air still.

EDIT: Actually, before you do that.. how many amps does your 12v rail have? When a fan starts, it takes something like double or triple the amps to give it the intial start up. Could be that your PSU doesn't provide the power to start it. I base this theory on the fact that I've never heard of that make of PSU (which doesn't mean it's junk, maybe I've just never heard of it) and the fact that your computer sometimes doesn't start, lol.

But try cleaning it and see what happens. Maybe because it's dirty, and it doesn't start sometimes, maybe it's robbing all the power and then your computer doesn't start? Who knows..try cleaning.

First off thanks for the reply.

I keep my computer very clean, and the PSU isn't junk! =)

I'll try that first method, but I have a feeling the fan just isn't getting that kick to start it up.

my guess is that the cpu temp is below the spin up temp for the fan. remembering that the big typhoon makes a decent passive cooler on its own. my typhoon does this.

So what should I do? Cause at the moment i'm having to open my case and phsically tap the fan so it starts up...

worst case scenario, you could just get a new fan

check the temps, change the temp for spinup in BIOS

Or connect the fan to a molex connector from the psu. Adapters cost just a few dollars.
