Is there some way to replace the 2000's fan with a quieter fan without compromising the cooling system? The fan is unacceptably loud for use in a studio apartment. I am almost thinking of a 3000 solely on the reports that it is as quiet as the 1000. Why the noisy fan anyway? It sounds like the 1000 has at least as high demand for fan-power due to tortuous ventilation routes! hints, advice, comments, commisery all welcome. dylan dylan@cs.washington.edu

I ordered the fan from Digikey and it looked to fit exactly in place of the current one. Only problem, earthquake. The fan was sitting on top of my computer when the Loma Prieta struck last October (I'm in Santa Cruz, only about 10 miles from the epicenter). The fan, I think, went sailing out of my third story window, never to be seen again. I can't think of what could have happened since it was there before the earthquake and gone after. So that's my earthquake damage I guess. Anyway, personally, I'd go for the Digikey fan. It is incredibly quiet and easy to install. I needed to solder the wires from the fan into the connector off the old fan but I didn't have a soldering iron on me. I hope this helps.

My fan is driving me crazy!!!! References: <5559@portia.Stanford.EDU> Status: OR Amiga 2000 Stealth Fan Instructions Tired of listening to that Jet Engine Turbine fan on your Amiga 2000? Well, heres a solution I came up with that cuts the fan noise down by at least half. Over the course of the last 6 months, the noise of my Amiga 2000 fan slowly increased as the bearings for the fan started to make more and more noise. Since my warranty was out, I decided to go ahead and pull the power supply and check out the fan. To my surprise, when the fan is seperated from the power supply and held by hand, it was almost whisper quiet, except for the noise the bad bearings generated. But when mounted in the power supply, the noise was terrible. Drawing on my experience in the Submarine Navy, I realized that it was a simple problem of sound isolation. The fan had been popriveted onto the aluminum case for the power supply. This direct metal to metal contact allowed the noise vibrations to transfer from the fan to the power supply, and from there to the rest of the Amiga case, amplifying the sound generated by the fan. The solution? Well, I went to the local hardware store and bought four 1/8" x 1" round headed bolts with nuts and lock washers and four round rubber grommets with a 1/16" slot for the power supply casing and a 1/8" hole for the screws. These parts should only cost a couple dollars. Now, installation. First turn the 2000 off and unplug the power cord from the rear. Next, remove the 5 phillips head screws holding the cover on, and remove the cover. There is one screw in the top middle of the back, and 2 screws on the bottom of the cover on each side. Next, remove the 2 screws on the back of the 2000 for the power supply, one is located at the top on the inside edge of the fan, the other is at the top, just above the power cord connection. Now remove the 2 screws that mount the power supply to the metal mounting bracket for the power supply and drives. These screws are at the front of the power supply next to the protective cage. Now, unplug any power supply cords coming from the power supply to the motherboard and disk drives. You should be able to remove the power supply now. Ok, now to remove the fan, use a 1/8" or 5/32" drill bit and drill to drill out the rivets connecting the fan to the power supply. Next you need to drill out the fan mounting holes on the power supply to accomadate the rubber grommets. The grommets I used required a 5/16" hole. Now install the grommets, and mount the fan using the 4 bolts, lock washers, and screws. I found it was easiest to install the bolt at the bottom right corner of the fan first. (Looking from the rear of the power supply) Tighten the screws until snug, but don't overtighten. One last item, you should trim any of the rubber grommet sticking out on the side of the fan cover plate so that the power supply can fit snugly against the rear of the 2000. That's it! Now just re-install the power supply and the 2000's cover. Glenn Nielsen CIS 75115,444 BIX gnielsen -- Jimmy Liberato ...!amdahl!drivax!liberato "My life is conventional and uneventful.

It's much quieter and there are no modifications needed to make the fan work.

The only thing that needs to be done is to solder the two wires off of the old fan onto the new fan. Don't get the Radio Shack fans! A friend did that and after trying about four of them, he gave up trying to get a quiet one. They all were very noisy and some even rattled, like they already had bad bearings or something. Good luck. -- _____________________________________________________________________________ |Jon Granrose |ARPA: odin@ucscb.UCSC.EDU jonathan@sco.com | // Only | |Cowell College, UCSC| odin@pilot.njin.net odin@ucscb.bitnet|\X/ Amiga!| |Santa Cruz, CA 95064|UUCP:..!ucbvax!ucscc!ucscb!odin | `-----------------------------------------------------------------------------'

I am currently using an Sprofran on my 2000 and I can barely tell it's there. Works damn well too... sometimes makes the breeze around the back a little too cold for the typing fingers :-)

Take a few minutes to clean them and it should run alot quieter. Mine did. >dylan >dylan@cs.washington.edu -- Stephen Menzies email: menzies@altitude.CAM.ORG
