Might have overspent just a little on a cooling fan ... been looking for this one on and off for about a year or two to recreate my lanparty/clangaming machine from back in the day. Came across one on ebay for about €80 excluding shipping more than a year ago and thought to myself "No way am i spending that on a fan" ... then the ad was gone for some time. Ad came back with a pricebump (seller probably had more than one) ... said i was surely not spending more than €/$100 on that fan even though it's rare. There is still a seller (in Greece i think) on ebay selling one ... for an outrageous $140 excl shipping ... simply not worth it (plus you will probably end up with a knocking fan like i did)
Then a stroke of "luck" and recently found one NOS in the UK for £50 ... expensive but won't be getting much more chances on getting one. So £50 for the fan and £40 shipping and import tax to EU ... paid something around €100 total. (Stupid expensive tbh)

When it came in it became clear the box was very yellowed ... praying that the fan itself was not discoloured and luckily it was just the plastic sleeve (you can see it on the pic on the right hand side.

Well on to testing! Hoping the 20 years in a box won't have harmed it (bearings/lube). Started it up and ran fine for all of 20 seconds ... then it started to make a knocking sound. Not the typical rattle but more a constant knocking .. it's the top fan (gold one) making the noise. Problem is i don't see a way of getting it off the hub. Both fans have their PCB pointed at eachother and only the bottom fan has a sticker that probably covers the circlip (the top fan is sealed at the top).

Two pics are from 20+ years ago when i used to run that exact type of fan on my lanparty machine. Pics didn't do it justice but it were the only ones i could find where you could actually see the fan (nevermind the dust .. flash didn't help)

So now i need to do two things .. find out if i can convert this thing to a 3pin connector instead the wire spaghetti going to a pci bracket with a pot on it .... and fix that damn knocking.
Also to be honest the fan was kinda "meh" at best ... also i can remember my example started knocking aswel after a few years and i probably took it apart destroying it in the process. Was great for turning it up to max power at lanparty's though because you couldn't hear it anyway above the ambient noise.
