Re: [OT] Making CPU fans spin [was: Re: Seeking advice...]
Andrei, > Is WD40 suitable for such fans? The bearing is covered by a plastic cap or a sticker or both. Very little of any sprayed lubricant will reach the bearing. Very similar to spraying a jet of oil at the wheel of a car to "fix" a bad wheel bearing. Also, the spray will coat parts which don't need it. That will collect more dust and help polymers deteriorate. If you really want to fix it, the fan must be dismantled. Not difficult; just requires patient & careful effort. Once it is apart the repair must be appropriate to the problem. As mentioned a few days back, a ball bearing will need cleaning and oiling or replacement, depending on condition. A sintered bushing will need to have wear particles cleaned out. Fresh oil in a dirty bushing won't help for long.

No, WD40 won't last use sewing machine or 3-in-1 oil. I've never disassembled one of these little muffin fans that come in the PC or power supply but have had good luck just cleaning and oiling them. About every 6 months I take the fans out and clean the exterior with alcohol and Q-Tips removing the grease and dust that builds up. I then lift the sticker or pop the little cap on the front (blade side) of the fan that covers the bearing and put a drop or two of oil on the end of the bearing and recover it. I haven't replaced a fan in this old P1 system since I started doing that. HTH, Mike -- Satisfied user of Linux since 1997.

FYI: don't go cheap in the lubricant. If you want to mess with the fan lubricant, get a can of the highest quality bearing lubricant you can (it will NOT be liquid), and instead of six months, it will last for six years. Never EVER use anything that will change its flow density or "cook" in the -10°C to +120°C range. Don't use anything that has solvents (like WD40). And you will have to clean the old stuff from the fan as Peter told you. If you DO remove the thermal sink assembly, be advised that you need high quality thermal compounds to replace the stuff Lenovo used, and you need to apply it _right_, so get the proper tools first. I.e. go straight to Arctic Silver 5 or one of the top-rating (AAA+) compounds. Do NOT use anything conductive or any of the ones who react with other metals. OTOH, just by doing a proper Arctic Silver 5 application AND cleaning the fan, you can expect a drop of at least 5°C on the CPU when compared with the performance your ThinkPad had fresh out-of-the-factory. After it cures, anyway. The thermal interface between the thermal sink and the CPU (and if you're very unlucky, the GPU or the northbridge) *can* crack on thinkpads. It is your number one suspect if a thinkpad ever overheats and shutdowns (or engages the emergency CPU clock modulation) with a still working fan (even if the fan is somewhat dirty). -- "One disk to rule them all, One disk to find them.

This is the first thing to do as soon as I have "my" Debian running on the "other" machine ;) Is WD40 suitable for such fans? In my experience, compressed air does wonders and may even spare you the effort of having to dissemble your laptop. I'm lucky to have access to a compressor, but canned air should be just as good. The point is to thoroughly clean the laptop with compressed air through all of its orifices; there'll be clouds of dust coming out from everywhere, so don't do it on your favorite Iranian carpet. If the problems persist, WD40 can probably help too, but I wouldn't advise using it *before* thoroughly cleaning the part. And, once you clean it thoroughly, you may find out that you actually don't need WD40 at all. -- Cheerio, Klistvud http://bufferoverflow.tiddlyspot.com Certifiable Loonix User #481801 Please reply to the list, not to me. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

This is the first thing to do as soon as I have "my" Debian running on the "other" machine ;) Is WD40 suitable for such fans? If you think lubricate the fan to get a better spin I would rather take a fine machine oil, but WD-40. I'm not sure that "fine machine oil" is best translation, it is a fine oil used in precision mechanics, eg for repairing watches. I think that 1 or 2 drops will be fine, at least worked for me.
