Unbalanced Fan??

[JigPu]

OK, here's the thing. The fan for my P-90 heatsink is messed up. It has been running strangely for a long time now, but it just got worse. Basicly, you turn on the computer and the fan spins up. Then, after reaching some speed, the blades and the thing they are on starts having a barely noticible wobble and drops speed significantly.

Usually, playing with the fan will get it back to normal. However, just today, I found out that "normal" wasn't. I messed with the fan, and it sped up like normal, only the pitch kept going up, and when it finally stopped, I put my finger by the HS, and WAY more air was coming out than ever before.

I wouldn't mind if it stayed at my "old" normal speed, or new, but now it won't spin up to either no matter how much I mess with it. It spins, then starts wobbling a little, and the fan goes REALLY slow. I don't think the CPU can handle such little air for a long time. Usually I can fix it, but not now!!

Is there any way to balance a fan so it won't wobble??

Sounds like the bearings are shot. It happens. Just get a new fan. Check some of the other threads here and you'll find lots of recommendations for sources.

chnces are it is 40 or 50mm, go to a local pc shop to see if they have any spare, it is quite hard to get anything under 60mm nowadays on the internet

if its only for a P90, then I wouldn't worry too much about the chip frying :)

Hmm.. P90.. fan not spinning up... (consults 'manual' on such matters)... SOLUTION!

While the computer is running.. you need to get the fan 'aligned'. To do this you hold up a very powerful eletromagnet (one used for picking up cars in the junkyard should do) to the processor and engage it. That should make the fan spin even on the spindle.

Now.. you need to make sure that it doesn't lose its concentricity again. The 'manual' says that an arc welder should do the job from here. Just fire that baby up and let her rip. If you want to really make sure use an oxy-acetalyne torch to do some touch ups.

Next.. the manual says to go buy a new system. What the hell? Dang thing.. last time I buy computer tech manuals from a bunch of crazed Macintosh Cult Followers.

p.s. I'm just joking around.. go buy a new fan like the other guys said :)

Yep it is a bearing, had it happen to me a couple weeks back.

dude if it's a P-90 you could probably get away with just aiming a fan at it, or making sure that you have really good case ventalation. Ya want to hear something SICK!!

I was working on a Gateway AMD 450Mhz system and the darn thing DIDN'T EVEN HAVE A HS FAN!!!!!! The power supply fan was above it and it was sucking air out. I guess they thought that would do.


Cool on

a p90 won't generate enough heat to fry itself, as long as it has it's heat sink it sould be fine

wouldnt buying a new fan be more expensive than buying a new p90???
