bibilit Posted January 27, 2016 Report Share Posted January 27, 2016 I have collected an early SE monday (two 800k) I removed the casing yesterday to have a look inside, and instead of the square fan, this has a cylindrical fan. I haven't seen any of those before, but looks original. Common setup ?? Quote Link to post Share on other sites
Compgeke Posted January 27, 2016 Report Share Posted January 27, 2016 It's original, only found on early models. Heard them referred to as hamster and squirrel cage fans before. Quote Link to post Share on other sites
bibilit Posted January 27, 2016 Author Report Share Posted January 27, 2016 That's the one, found pictures with the "squirrel cage" tag, a bit noisy. Quote Link to post Share on other sites
uniserver Posted January 27, 2016 Report Share Posted January 27, 2016 i like the squirrel cage fans. I like the air flow, and the ones that i have are silent, products with a fan like that were usually High-End from the era. Quote Link to post Share on other sites
Elfen Posted January 27, 2016 Report Share Posted January 27, 2016 It's common for the early SEs to have "squirrel cages". I prefer them as they have better air-flow and keep the SE cooler. Quote Link to post Share on other sites
unity Posted January 27, 2016 Report Share Posted January 27, 2016 The first round of SEs did have that fan. It was found to be noisy so Apple issued a "silent" recall and replaced the fans with the standard box fans. If you look at the board, you can see it has mounts for both styles. So someone at Apple was thinking. Remember the SE was the first compact with a fan. With the recall, the squirrel fan units are a little harder to come by. But since the SE was a well sold machine in bulk, its not hard to come across a large quantity from a university, or such, that still have the original fans. I think the first one I saw was a couple years ago, before that never an SE with one. Now I have several. Quote Link to post Share on other sites
uniserver Posted January 27, 2016 Report Share Posted January 27, 2016 i think what happened is they plug up full of dust and begin to vibrate and cause NVH that way... but the 3 or 4 that i have been around move a lot of F'in air efficiently and quietly. Quote Link to post Share on other sites
CC_333 Posted January 28, 2016 Report Share Posted January 28, 2016 I bought an SE from it's original owner, and it had one of these fans. I upgraded it to the later box fan, but in retrospect, maybe I shouldn't have? I still have all the parts from the old fan, so I could always put it back if I *really* needed to. c Quote Link to post Share on other sites
bibilit Posted January 30, 2016 Author Report Share Posted January 30, 2016 I have cleaned casing, drives and the dusty logic Board, then gone for a test, working fine.. The Squirrel cage fan Quote Link to post Share on other sites
SE30_Neal Posted January 30, 2016 Report Share Posted January 30, 2016 I'm nervous as I've just stripped my SE/30 down and cleaned it up ready for recap, hope it works when I put it back together. Quote Link to post Share on other sites
uridium Posted March 12, 2016 Report Share Posted March 12, 2016 I've got one of these in my SE. Actually moves a heck of a lot of air. No squirrels here in .au ..so I'm naming it the "whirly-gig" .. you'd have to be from west.au to get that though. Quote Link to post Share on other sites
olePigeon Posted March 12, 2016 Report Share Posted March 12, 2016 Now I want a squirrel fan. Quote Link to post Share on other sites
olePigeon Posted March 12, 2016 Report Share Posted March 12, 2016 Whatever it is, I'm sure it's poisonous. Quote Link to post Share on other sites
Paralel Posted March 13, 2016 Report Share Posted March 13, 2016 (edited) If Australia had squirrels, they'd likely spit venom or something. Everything down there wants to kill everything else it seems. Edited March 13, 2016 by Paralel Quote Link to post Share on other sites
Schmoburger Posted March 14, 2016 Report Share Posted March 14, 2016 Nah Australias not too dangerous... hang on, is that a white-tail spider? Shit. Halp. Quote Link to post Share on other sites
SE30_Neal Posted March 14, 2016 Report Share Posted March 14, 2016 You do seem to have all the nasty critters down under, back here in blighty (uk) we have lots of pesky squirrels though, giving you the evil look and destroying your garden plants! Damn you squirrels! Haha Quote Link to post Share on other sites
uniserver Posted March 29, 2016 Report Share Posted March 29, 2016 drake stuff back then was high end! Check out its cooling fan. 2000watt ham radio amplifier. http://www.ebay.com/itm/DRAKE-L-4B-RF-Linear-Amplifier/161993284503?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D35624%26meid%3Dbf6ac17373484849a87c0eeccae33eef%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D141925359184 Quote Link to post Share on other sites
Paralel Posted March 29, 2016 Report Share Posted March 29, 2016 Looks like you're coming up against standard circuit tolerances, a typical circuit can only handle 2400 watts. After that I guess you need a special industrial installation? Quote Link to post Share on other sites
68kMLA Supporter rsolberg Posted March 29, 2016 68kMLA Supporter Report Share Posted March 29, 2016 I imagine 2000 watts is its rated output power. Assuming 70% AC to RF efficiency, it could draw over 2800w- meaning 800w of heat for that fan to move! Uni, I'm curious if I'm even close. What's the supply voltage, is it AC or is there an external power supply? Quote Link to post Share on other sites
Paralel Posted March 29, 2016 Report Share Posted March 29, 2016 Well, if its a standard 20A circuit, it can't pull 2800. It would be 400 over the limit. Quote Link to post Share on other sites
68kMLA Supporter rsolberg Posted March 29, 2016 68kMLA Supporter Report Share Posted March 29, 2016 Doh! I thought this was Uni's- I didn't see the eBay link. The seller has it configured for 240v AC. It has a NEMA 6-20 plug installed in photos. That requires a 20A 240v circuit. Quote Link to post Share on other sites
Paralel Posted March 29, 2016 Report Share Posted March 29, 2016 (edited) 240V service these days is fairly uncommon, without one requesting such. My house is a mess. 100A service, 15 amp circuits from the 70's. Needs to all be ripped out and throw away. Edited March 29, 2016 by Paralel Quote Link to post Share on other sites
uniserver Posted March 29, 2016 Report Share Posted March 29, 2016 yeah guess hams that run amps like to have 240 volt outlets, the amps's run more efficient and cooler at 220/230/240, Quote Link to post Share on other sites
uniserver Posted March 29, 2016 Report Share Posted March 29, 2016 yeah that amp at full drive can output 2000 watts, witch is 500 over the legal limit. it has a couple of these bad boys in it. Quote Link to post Share on other sites
slomacuser Posted June 16, 2016 Report Share Posted June 16, 2016 I was browsing old Macworld (April 1988 and 1989) magazines and found this (see picture below) :9 Quote Link to post Share on other sites
