Now wrinkle # 2
Ever had afan go bung and all you have is soem old ones or the one that is playing up. Now mostly it is through lackof or drying up of the lubrication.
My methos involves firstly cleaning the fan as previously described and then applying some lube I usually use one of those produts that get rid of moisture and loosen rusted bolts / nuts - WD40 or RP7 and follow it up with some light sewing machine oil.
* Remove the fan from the case, PSU CPU heatsink etc
* First clean the dust and rubbish from the fan blades and venturi as stated using methylated spirits.( I use hogs hair brushes on all computer stuff to minimise the production of static)
* Once clean carefully peel back the round label on the fan body usually away from the domed and / or intake side)
* Carefully prise out the small neoprene plug covering the bearing aperture (I use an old penknife)
* Drop in some of the free up lube (WD40 or RP7 whatever it's called wherever you live)
*Connect to a power source (I have an old PSU rigged for this purpose and testing drives) and turn on the power.
* Let the fan run for some time say a couple of minutes - some that are really quite hard to turn may need a bit of assistance.
* Turn off the power
* Then drop in a couple of drops of light machine oil (I use Singer sewing machine oil)
* Restart the fan with the power supply.
* Let it run again for a few minutes - 2 is usually enough.
* Take a twist of kitchen paper towel and gently blot the excess out of the bearing cavity.
* Replace the neoprene plug
* Stick down the round seal - it might need touch of supaglue - depends if you have spilt any oil on the contact surface.
* Replace the fan to its position - wherever that was.
Result is you now have a fan that will run for as long as you want it too or until you can replace it.
Cost $0.05 as opposed to $9 thereabouts for a new fan plus the wait (and you maynot nee to replace it!
I do this to all old revivals / rejuvenating / dissembles and have never had a problem.
In the pics you will see the materials needed. The small lube bottles are ones that is for instilling ear drops in dogs and cats (comes with screw on top) and one that is an old eye drop container that I have "modified" with an intravenous cannula glued into the removable top - you need to cut down the syringe end first as it is too long. The other is a draw up needle (blunt) and same thing - cut down to fit.
You may need to know some friendly medical person or health professional to get the cannullae - they are Teflon so flexible and the different colours are different gauges - depends on what you want. The very pale pink is the steel one - the cut to the syringe attachment needs to be about 1.5cm from where the tube emerges form the syringe attachment.
The other little gadget is a spatula for mixing the five minute epoxy glue and is fantastic for applying thermal paste to those older (and new CPUs) north bridges.
Oh the PSU is fixed on boot start - green to black and sealed with cloth duct tape and worked with the power switch - not pretty but does the job.
