Name: giggles
ok so i've had my system for a year and my fan noise is starting to bother me
today i am going to dust the whole case out and i would like it if i could grease my fans because they are getting bothersomedoes anyone know the proper grease i should use for case fans, a chipset fan, and a gpu fan? i have wd-40 and some doorknob grease junk and some silicon lube that i used for airguns...
any help is awesome, thank you
common sense isn't very common
They make a special grease for fans etc. Here's one example

It makes them think you're up to something...

For best results change the fan. If you want to try to lube the bearings you need to use a light oil. I've used WD-40 and sewing machine oil. Most of the fans have the bearing covered with a label. Carefully peel the label up. You will either see the shaft and bearing or a rubber seal. If there is a seal, remove it carefully. Put a drop of oil using a tooth pick in the bearing. Hand spin the fan. Put another drop of oil as needed. Do not over oil. You should not get any oil on the surface where the label is attached. Replace the seal, then the label. If the label is damaged, use a piece of plastic tape. Remember to use the oil sparingly, if the oil gets on the blades then the dust and lint will stick to the oil.

Believe it or not, I use 90W gear oil. I peel back the label, dip a toothpick in the oil, then put a drop or 2 on the bearing. Work it back & forth a bit, then seal it up. I usually run the fan with the sticker side up for a few seconds to get the oil worked in, then I reinstall it.

"Believe it or not, I use 90W gear oil."
That's heavy, brother. How long you been into that?

If at first you don't succeed, you're about average.

I just love the smell of the stuff...LOL!
I realize that lubing the bearing is just a temporary fix & that the "real" fix is to replace the fan. But I've experimented with a few different things to see what works best & provides the longest "temporary" fix. I've tried WD40, 3-in-1 oil, motor oil, grease, petroleum jelly etc. I had some leftover 90W oil after replacing the axle seals on the rearend of my truck, so I gave it a shot...I've been using it ever since.

The plain bearings on fans are sintered bronze bushes. This means they are deliberately porous, so when they manufacture them, they are preloaded with a special grease that is soaked up. Since you can't replace the grease, the next best thing is light oil, such as sewing machine oil. You need a few applications, spaced out, so that the bearing soaks up the oil. Avoid 3 in 1 and WD40 since they're not intended for this kind of application. I have a power supply fan that's been going for fifteen years with this treatment.

I don't think the bearing load is high enough for MolyD to matter. For sleeve bearings all is needed is a low viscocity oil film.

errr, ok so what i did was i pulled out my vid card and dusted it and removed the tiny little fan (asus v8200 deluxe geforec 3) and i peeled back the sticker and got my mom's sewing machine oil but i guess i put too much in there
actually, i know i put too much in there lol
so that was bad but then when i put the fan back on the heatsink, i put it on off-center and fan blades were touching the hs
so i turned on the computer and i said "wow, this really worked, there's practically no noise whatsoever" lol
i then shutdown and re centered the fan but after all the stuff i did to it, it now has a really bad rattle to it so i jimmy rigged an 80mm fan with lights in place of iti thought it was pretty sweet
my temps are the same but the computer is much much quiter, i was turning it on this morning and i did a double take "is it on?" because it was so quieti think that will be the last time i try to grease a fan, i have the $12 to replace any noisy problems
the chipset fan on my abit nf7s is next, i need to replace that whiny POS nowand maybe get some of those rubber hdd gaskets to help with metal to metal vibration on the case
anyway, thank you guys for the information
it was fun messing with my mom's sewing junk and now my computer is much quietermaybe if i ever figure out how to upload pictures, i will take one of my new fan and post a link in this thread
