Ok it occured to me from time to time a lot of us have problems with noisy fans, either from CPU, Graphics cards or Onboard Chipsets. I decided after a little while debating if I should try do a very small and crude tutorial and show people how to strip and quieten down their fans.

So forgive the crudeness and poor quality of the pictures ;)

I will hopefully be doing a small video soon to accompany this tuturial as soon as I can find the time. Hopefully it will prove a bit more informative and easier to follow. All I need to do is find someone that is willing to host if for me..

------------------------------------------------------------------
OK first of all I wont go into detail on how to take a fan out or off of your system I think that is pretty much straightforward. However the first picture shows you basically what you need to hand.

1 Fan (DOH!)

2 Pins preferably the sort you see in the picture. The small bead of plastic help it not to slip between your fingers.

3 A steady hand

And finally oil of some sort. There are many kinds, and to be honest probably WD40 would do the job just aswell, however I have decided to use some Castrol GTX that I had laying around from my last car. (May she rest in piece amoung all the others waiting to be scrapped GRRRR) However some light machine oil as Mucks suggested is probably more than ample

Pour a tiny amount into the cap or anything else that wont spill easily (and I mean tiny you dont need much at all)


Right now the fan, turn the fan unit over and look or feel for a small hole underneath the sticker. Peel the sticker off if it has one. Bear in mind not all fans are and will look the same under the sticker. In this case the spindle had a small plastic cover over the top. You should see a small steel rod in the centre, around that should be a very small plastic split washer. This is the tricky part, using the two Pins gently prise the washer out. Keep in mind you need to do it carefully as you do need this to put back on. The washer does sit into a notch in the rod very slighty so please be carefull and patient.

Ok once you have dont that you can gently remove fan from the rest of the unit as below. One thing i want to mention is other fans I have come across have had a separate ball bearing spindle inside the hub take care not to lose it.

Ok clean inside the hub of the main unit with a cotton bud or a dry cloth to get rid of any debri that may hav accumulated over use. Now get a pin that you used earlier and apply a very small amount of oil from the cap to the centre of the hub, or if you have one the Ball bearing spindle (Very important. You literally only need one drop)

Once this is done slot fan back into main unit again and carefully replace the small split Nylon washer you removed earlier again taking care not to damage it (use both pins to position into place)

Put sticker back onto rear of fan and reconnect.

That's a great little article and I would encourage Ian to list it as such. :thumb:


However, I have to wonder ... why bother? Are fans that costly?
Your choice of oil seems a little on the heavy side. ;)

Now don't get me wrong here but I personally haven't paid much for any "replacement" fans, and, where possible, have always tried opting for a passive alternative, or even none at all.


I can just see PSD now stripping all his fans down just to make them quieter. :D


Still think Ian should post this on the front page though. :cool:
 
Thanks m8.

The oil as I said was just laying around however was ideal for this kind of thing Metal against metal so to speak.

Its not just a case of buying a new one is it really its all about saving money. If its broken why not fix it ;) Remember you have to add postage to stuff you buy aswell! It can all add up.

I thought it was about time I offered something to the forum and I thought something like that may come in useful after all the talk about noisey fans recently :D

No, I take your point ... I do like the article ... you may want to edit it in favour of some light machine oil, the type they use in hair clippers or sowing machines. ;)

I tend to forget I used to buy case fans by the box ... and tried also to stay well clear of anything with one of those ridiculous "gimmicky" looking HSF.

Yes I have got my knife ready!!! :)

now which one first.....
 
Great article TriplexDread!

I run a PC repair centre and manufure PCs - it's amazing with the amount of fans - PSU, HS&F, northbridge, VGA. The order/amount of fans that need replacing are as follows;

1. Northbridge
2. VGA
3. HS&F
4. Case
5. PSU

Why on earth don't mobo manufacturers use passive northbridge coolers? We regularly have to strip them and oil them. The best thing to do when they do fail is to replace the northbridge HS&F with a passive cooling solution.

Fortunately Asus now has the new Silence series of their popular VGA cards - using those in our PC manufacturing and helps to reduce noise - needs good passive cooling (case fans).
 
Thankyou, and I agree it passive heatpipe cooling of a sort should be integrated into motherboards eventually

Spread the word about it. I hope it helps ;)
 
Excellent article TD :thumb: - I love stripping things down out of curiosity or just to see how they work, so this is ideal for me!!:D
 
Great article Triplexdread ... £5 saved is £5 in my back pocket :thumb:
 
I havent but if i do ...your article will possibly save me dosh :thumb:
 
Well it's certainly saved me some m8 ;)

I wanna do a video to accompany the pics but finding the time to do it really

I'll get there eventually
