| 348463 | 2005-04-24 23:47:00 | when a psu fan is noisy, it doesn't mean the psu is stuffed. what i do is use a drop or 2 of 3-in-1 oil into the fan. you do have to open the psu, take out the fan, take off the sticker cover, then use a jeweler's screwdriver & prise out the little rubber/plastic cover - use only a drop or 2 of oil, then put all back into place. the fan needs oil for lubrication. may take 1/2 hr. i have been doing this for years, saves clients money & i make money. if you don't want to do all that, replace the psu, but the oil can dry out within a year, depending on usage - it's silly to buy a new one each time. |

| 348464 | 2005-04-25 00:23:00 | when a psu fan is noisy, it doesn't mean the psu is stuffed. the fan needs oil for lubrication. It usually means the bearings are on the way out. This person still has his PSU under warranty. I would recommend he RMA it. |

| 348465 | 2005-04-25 00:41:00 | that is possible & if it's under wty, return it. but i have fixed lots of fans with a bit of oil - lasted longer then the computer. a lot of techs don't know about this or too lazy to do it, but it's so easy money & customers are happy. | quarry (252) | ||
| 348466 | 2005-04-25 00:49:00 | a lot of the fans (normally cheap ones but not always) use sleeve bearing which the oil trick works fine most of the time. however other fans use sealed ball bearing and oil won't get in them and the ball bearings are often stuffed so the oil only quietens it down for a week or so. no need to buy new power supply, just replace the fan in it. its usaully an 80mm x 20mm tho a few have odd sized ones. | tweak'e (69) | ||
| 348467 | 2005-04-25 00:54:00 | power supply makes a bloody racket I think thats the difference between shot bearings, and a bearing that needs oil. The bearing looking for oil will usually make a slight racket, that gradually gets worse. The shot bearing will just collapse. Another possibility... may be a shot spindle bearing |

| 348468 | 2005-04-25 01:32:00 | I agree with Quarry here. Is it a generic PSU that came with the case or is it a special one you purchased (Topower, Antec, Entec e.t.c)? For the generic PSU you should just re-oil it and not bother with the RMA. For the special one you should get it replaced. |
