Re: Excessive fan noise - Quicksilver 2002
... an update. My replacement fan is in transit, but in the interim I disassembled the power supply and removed the old fan - a bit of a challenge due to the tight fit and various items glued to its case. I removed the label carefully drilled a small hole (1/16) into the hub (there was no removable cap under the label), and fed several small drops of 3-in-1 machine oil into the hole. After manually rotating the fan for several minutes, the fins rotated easily. I sealed the hole with black electrical tape, replaced the hub sticker, and reassembled the power supply. The fan started up, is much quieter, and is really pumping out the air. I hope that this will keep me in business until I can replace the fan with the new one. Thanks to everyone for your advice and comments. --Bill On Mon, Jul 2, 2012 at 10:11 AM, William Tomcanin wt8091...@gmail.comwrote: Thanks, everyone. I've bought a StarTech.com 80x25mm Dual Ball Bearing Computer Case Fan (rated at 32 cfm) that I'm going to use to replace the PSU fan. Hopefully the ball bearing will last longer than the sleeve bearings that I think are used the existing fan. Incidentally, since I last gave the existing fan a good flip to get it started, it has continued to spin, although I think at lower rpm. In any event, it's coming out soon.

Re: Excessive fan noise - Quicksilver 2002
Thanks everyone! After some cleaning and further investigation, I discovered that the power supply fan is binding. I had to flip it a few times with a toothpick in order to get it moving, albeit rather slowly. I suspect that this is driving the internal temperature too high, and is resulting in the other fans running at higher speed. It looks as if I will need to either replace the fan or power supply soon. I know that you replaced your fan, Peter, has anyone replaced the full PSU? If so, how difficult is it?

Re: Excessive fan noise - Quicksilver 2002
It's not too difficult. http://manuals.info.apple.com/en_US/powersupply.pdf shows replacing a G4 Grey Tower PSU, http://manuals.info.apple.com/en_US/g4mdd-fw800-pwrsup.pdf shows replacing a PSU in a MDD There doesn't seem to be one specifically for the Quicksilver, but IIRC, it's quite like the Grey Tower (Sawtooth, Gigabit E, DA etc.,) internally.

Re: Excessive fan noise - Quicksilver 2002
With the usual care and precautions PSU complete swap relatively straightforward ( You have to remove the optical drive chassis to create the space for withdrawal) - there are step by step illustrated guides out there - I've swapped PSU's in my QS and QS 2002. The problem is finding them at prices that don't call the whole project into question especially this (UK) side of the pond. My lucky break has been finding stripped end of use QS class machines intended for disposal - with working PSU's still in place. I'm in need of another (hint). * *Tim Martinhttp://www.cityandguildsartschool.ac.uk/staff/foundation_staff/tim_martin e timjomar...@gmail.com* Clapham Park* *London* 17 1GHz AL Powerbook G4 (Leopard) | 2.7 GHz MacMini i7 c/w 23 Cinema HD (Lion) Powerbook G3 Series Wallstreet - (now G4 500 Sonnet) (Tiger) | Power Mac G4 Quicksilver 2002 - now Sonnet Duet 1.8 GHz (Leopard) | Quadra 800 - (8.6) (now Sonnet PPC 100 MHz) -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: Excessive fan noise - Quicksilver 2002
I know that you replaced your fan, Peter, has anyone replaced the full PSU? If so, how difficult is it? No, not difficult. The three Allen screws on the outside are metric, not Imperial. The threads are M3.5-0.6, too, so DO NOT make a mistake and assume they are the much more common #6-32. The internal screws are also M3.5-0.6. Once the PSU is out, you can replace just the fan by cutting off the cable which terminates in a proprietary connector on the PSU's printed circuit board and soldering it on to the replacement fan. Insulate with heat-shrinkable tubing. It is a 12 volt fan of a conventional size. Just get the same size as a replacement. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: Excessive fan noise - Quicksilver 2002
Thanks again for the responses .. I assume the PSU fan is 80 x 80 x 25 mm, at least 32 cfm? Any restrictions on current draw at 12 v? Nope. The fan is supplied off of the +12 volt bus, which is common to all +12 volt devices, such as HD, and, indeed, CPUs in Intel Macs. I have ... in an earlier lifetime ... resurrected many an Apple Network Server PSU simply by substituting a generic 12 volt fan unit for the original, failed one. These 12 volt dc fans, and the very much quite similar 120 volt ac and 240 volt ac fans, are made world-wide, and most PSU or system manufacturers simply buy whichever one is the lowest cost, at that particular moment in time. Not a lot of rocket science is involved in cooling fan selection. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Thanks, Bill I had problems with fan noise and overheating with my MDD dual 1.25 - resulted in me stripping it bare and performing certain 'modifications' - some of them to the fan and airflow.

Re: Excessive fan noise - Quicksilver 2002
Thanks, peter. The one thing I didn't do was to clean the actual fan blades. I will do that immediately. The noise doesn't appear to be a whine that I normally associate with bearing wear, but seems to be more of a noticeable whirring. If additional cleaning doesn't improve the situation, I'll start looking for a replacement fan.
