Northbridge fan too loud after cleaning

[neutralizer]

My northbridge has one of those small fans, but after cleaning it with canned air, it's now making a grinding noise. Is there any way to silence it or reduce the grinding noise without installing a new hsf?

mine did that, i took it apart and oiled the bearing and now its smooth as silk. but i replaced it anyways with a passive heatsink later on.

I think all it needs is some oil.

Will WD-40 do?

Oh btw, the fan now spins up, grinds, and then silences itself, slows down and shuts off atleast abit eq reports the fan as "off". Did the fan just die?

I would suspect that it died.. Plug it in again and see what happens.
If it doesn't spin up or it spins down, maybe a new fan would help?

I don't know about WD-40. I just use some tube of oil thing that we've got at the shop.

Hmm... bleh I guess I'll have to buy a passive Zalman chipset hsf that matches my CNPS-7000. Is it bad to run the northbridge without the fan, there's still a small sink on it. I going to need to run it for the next 4 days without a functional fan.

i found it unable to overclock. i had to reduce my overclock by 10 fsb,

My $.02.

WD-40 is NOT a lubricant nor is it a cutting oil. It's a water dispercent.(sp?)

The bushing in the fan has worn to increased running clearence, it might just need a DROP of lite machine oil. Get a small bottle with a long
needle type dispencer. Using compressed air to clean directly at the shaft area can/will blow away what little lube is in there, also and much worse it can drive abrasive dirt between the shaft and bushing. In machine shops ppl do get fired for cleaning metal cutting machines with compressed air for the above stated reasons.

Enjoy

Yep, it started making noise after I put in compressed air, but lack of oil can make the sound, but it can't cause the fan to completely stop spinning?!

I'm not an expert!! But from hands on experience. Little or no lube plus the entry of dirt,
can/will cause abrasive action to take place. This abrasive action will cause the gringing sound you speak of in your OP. As the metal abrates itself these particals have nowhere to go. They build up in the area of clearence between the shaft and bushing and cause the fan motor to bind-up. Remember we are talking of a running clearence of around .001".
So these bits of swarf are very small indeed.

I'm here to learn not argue

Enjoy,because life's too short.
