New CPU fan making noise P4, 3 Ghz, Socket 775

[chkmg]

Hi, I have just assembled a new P4, 3.0 GHz socket 775 and GigaByte MB. While shutting down or booting up and at times when there is much load on the processor, the cpu fan makes noise. I changed my old power supply suspecting it to be the reason (thought its fan is going wild) but now with new one though it is reduced to 20% of what it used to be but still bit noisy. Any suggestions?
I have upgraded from Northwood 2.533 GHz and it didn't make that much noise with the old power supply. I do have all the other hardware that I used with previous CPU. ( 2x SATA, 1xCDRom, 1xDVDRom, 1xFDD etc.)

Regards,
Chkmg

Could be a bad fan. Try lifting the paper label up enough that you can get some oil in and try that. If it does help then get yourself some dry graphite powder that you can buy in a tube at the auto or hardware store for $2. Mix that in with oil and it works better and lasts forever. Be careful as the graphite stains more than oil does! But it works better too!

Also, if oil doesnt do the job, it could be just the fact that the fan has to be that fast in order to cool the cpu!

Many thanx Garebo, I will try that soon

What type of noise? Air "rushing" past, "whine" of high speed, or "rattling" of the fan itself, due to worn bushings/bearings? Also, check that no wires, or cables can come in contact with the fan blades. The blades raise slightly when the fan is running.

This is the cpu fan right? You could also check any other fans for the same problem and the cure is the same too.
Also, some fans have a cover on them and the covers can get pushed down and the blades of the fan hit the cover when running so check yours and make sure thats not the case, not the cpu fans but any others, like if you have a northbridge fan. Use needlenose pliers to lift or pull the fan guard up just a bit, or a flat screwdriver to do the job.

Is your cpu fan temperature controlled? Is there any manual control for it? Control in the bios?

Thanks again guys, It definitely is CPU fan noise. It has reduced quite a bit after I changed the power supply. Now its only a bit on high side when booting or running some heavy applications. Its a brand new fan that came with the cpu so there might not be that rusting prbolem. Since it has reduced now, I think I can live with it .
There are no wires even near the blades, I can see through tranparent casing all the time. The noise is like too much air passing through. I checked the BIOS and it doesn't have any solution there.
Maybe if I could disable Hyper Threading then there will be less noise, but this is just my opinion. Any comments are welcome on disabling the HT thing.
Otherwise as I said, I can now tolerate it.

Sounds like the only "cure" is a different CPU fan. The cooler needs a certain amount of air for cooling. This can be accomplished by a small fan spinning fast, or a large fan spinning slower (quieter).

have you tried oiling it?

No, because I think being brand new it must not have the friction problem. But I sure am gonna do it to my Northwood CPU fan that I have taken out to put in another casing.
What should be the proportion of Graphite powder and oil? Is it 1:1 or some thing else? And how much is enough?

 

[garebo]

It doesnt really matter that much that you be that close, but somewhere around a 1:1. Basically i use the oil to transfer the graphite around as much as possible as fast as possible.
You just take a very small plate, something very small, i have a very small bowl and i mix a bit some each in it, about 1:1 and i keep it for next time as well, i cover it with plastic wrap in case of spillage as graphite stains worse than oil.
You peel back the seal on top and put some in. Some is your guess, whatever fills whatever cavity you find when you peel back the label. Dont be afraid to be liberal with it. I have these little pieces of flat wood stock, smaller than popsicle sticks, i got at the $1 store, they use them for crafts, to put glue on. I push as much of my mixture in as i can and clean the top plastic edge so the seal will seal again. But you can put in as much as you can of the mixture, it cant hurt the fan! You can use extra tape to seal the seal, but its not really all that necessary, unless the fan will not be on a horizontal plane, then you might want to seal it well, i have used small piece of duct tape on a case fan. I have taken the whole seal off and just used duct tape, up to each specific case.
Again, the oil is really only used to help distribute the graphite. Think of graphite as a top quality, thick oil, so thick that it needs a lighter oil to distribute it properly.
Now you can use plain oil to oil a fan but it wont last long, been there done that, as the oil dissipates thru friction and evaporation but the graphite doesnt evaporate or lose its friction ability, thats why they make it.

The cpu fan, some of them, even when new, can be quieted with this mixture. This mixture works with all computer fans new or old. Nothing to be afraid of, thats for sure, these materials wont hurt any fan if done the way i have suggested, been doing this for many years. I experimented with those removable ide tray fans, they are notorious for wearing real fast and being noisy as they are so very cheap to start with. The whole removable trays sell for as little as $5 so the fan inside it is worth about a nickel. The fan on a P 4 cpu costs probably about 20 cents or less to make.
I have even oiled some well known good quality fans as well.
Dont be afraid to try it and you will find it works and works well. Plain oil will not work as well and will not last very long either, but mixed with graphite it will last for years! I have fixed fans that were so bad they would barely turn with my finger pushing it! But no guarantee on those that are that badly off, lol.

Yeah right, so graphite is like "Viagra" that would bring life into lazy ones but not into dead ones, lol. Thanks once again for your detailed instructions. I will definitely try it soon and will let you know. Take care!

 

[garebo]

lol, hadnt thought of that, but i dont want graphite on my fishing rod, lol. Ill let you try it out, lol again. I dont need it yet, my case fan works great.

chkmg,

I would replace it. It may just be defective.
