Precision Oiler

Fan in your computer whining because the tiny bearing needs oil? Nothing does the job as well as a micro oiler. Owned one of those cheap leaky plastic pen oilers — the one where you squeeze and too much oil squirts out? Empire’s precision oiler allows precise oil delivery, one drop at a time.

Don’t mistake this for a pen — the push button on the end controls the flow of oil from the tip. The 5-1/2″ oiler, complete with screw-on cover and pocket clip, sports a stylish brushed aluminum finish. An O-ring sealed compartment keeps oil inside the pen, not all over your hands.

Getting oil where you need it and only where you need it should be worth $8.

    Thank you, Mr. Johnson. I haven’t been called out to replace a heatsink assembly or fan because of an end-user trying to quiet it down by _oiling_ it yet. This should make for a few more good stories.

  2. I’m not sure if you’re being sarcastic or not. But I guess like everything else now-a-days a warning label is required — “Hey dumb@#$ if you don’t know what #$%@ you’re doing inside this case grab a beer and call LMB”

    I have _oiled_ fans for years without any problems — extending the life of the fan and getting rid of the annoying whine. You remove the sticker, put a small drop of oil on the shaft/bearing-bushing, replace the sticker, and the fan work like new.

    I’ve done this, too. Granted, you have to be carful not to over-oil, and you do have to replace the sticker. But I’ve fixed a few this way. Of course, YMMV.

    For what it’s worth, we actually ran into this in the TM offices last week. The fan died in one of our older (and out-of-warranty) laptops and it whined like a stuck pig. Even with fast shipping we couldn’t get a replacement in until a few days later, so after almost going insane from the whining we pulled the fan and (I’m not joking — or recommending that you do this) soaked the bearing in oil for a few hours, then cleaned it up and re-installed it.

    It worked, at least until the new fan arrived. The bad news — it did smell a bit. Hey — you takes what you gets, right?

    Mr. Johnson,

    First: I’m sorry if I sounded like a jerk, I really wasn’t trying to. In the interest of being factual, here’s why I think oiling computer fans is a bad idea:

    Case fans usually squeak because they get dust in the bearings or collar. Oiling these parts will make the dust removal technique that everyone I know uses (canned or shop air) moot, and when the oil mixes with the dust it will gum up the fan.

    Modern heatsink fans are usually ‘mag-lev’ (there must be a generic term for this, but I don’t know it) and can be rather fragile because of it. If a heatsink fan is making alot of noise or otherwise seems to be not running within spec I replace it. I’d rather spend $5 on a fan than $150 on a new processor.

  5. LMB, Thanks for the clarification. You do make a good point.

    I should put some caveats in as well, I failed to mention blowing out the fan first, yes, make sure there is no dust causing problems, I thought that was just common sense. And like Chuck said, replacing the sticker is a must.

    I also have never had a “modern” processor fan (K5 fan yes) start to whine on me. I usually use this technique on case or GPU fans. All the fans I’ve used this technique on have had bushings, I’ve never had a fan that whined that had bearings or ‘mag-lev’.

    If I was charging somebody, heck yeah replace the fan, you don’t want to deal with them later. But on my own systems (I have five running right now and that’s like a record low), I know what to listen for and watch for and I have good redundancy so running the ragged edge of disaster isn’t a big deal…

    Having worked at an old motorcycle shop (with lots of old stuff) i’ve come across window and box fans that require (gasp!) occaisonal oil. you put a couple of drops of lube in the oil hole on top the motor, and suddenly the whole shebang is running MUCH better… and quieter.

    I’m half… no, 3/4 tempted to order this, just to see if I can shut some of the horribly loud fans on our computer lab switches up.

    … okay, I just ordered it. Precision tools are nifty! Also bookmarked the manufacturer’s website. Neeeat tools.

  7. Adam, Please let us know how the precision oiler works when you get it…

    I have a few of these and you can REALLY regulate the amount of oil dispenseddown to the smallest fraction of a drop. While they are tremendous for applying oil, if you are going to store them with oil in em, store em vertically as they are not terribly oil-tite. There is an o-ring thats supposed to seal the cover that goes over the applicator but it’s not very snug and if any oil leaks out of the applicator tip it will leak out of the cover.

    Adam, actually I purchased these specifically for oiling some antique fans I have and it’s perfect for getting to the bushing on the front behind the fanblades without removing the guard.
