Lubricating a stock intel fan

[magmag]

Sorry for my question about a kinda outdated cpu. I'm still running an old Intel Core i5 750 (Lynnfield) with stock parameters and stock heat sink. Everything is fine except that the fan is kinda heavy (it stops rotating immediately after I spin it) so I thought of lubricating it with few oil droplets (I got this oil with my hair cut machine). I tried removing the sticker - as shown in attached pic - but I found that there's no rubber to lift or something and lubricate under it (as I've seen on some youtube videos).

Is it the other side of the fan that has the stuff which needs lubricating? if so, that needs me to detach the fan from the heatsink in the first place. Is this possible or both are one unit?

In case of no possibility to do anything with this fan, I'm thinking about ordering from outside my country ARCTIC Freezer i11 CPU Cooler which looks huge as I've seen on youtube so I'm not really sure if buying this thing will work inside my Gigabyte Setto case and Gigabyte P55A-UD3P board.

Will appreciate your sincerer advice...

You'd not want to lubricate the fan, It will act in the way you describe because the fan is rotated by a DC Motor, so resistance is normal and is good for functionality. If there was little or no resistance I'd recommend a new fan, rather than a repair on existing fan.

Honestly however I would say get the new cooler as stock fans are usually cheap and do a mediocre job anyways.

the fan is not meant to be lubricated. If you input your motherboard and case into pcpartpicker.com, the site is pretty good at showing you only compatible coolers. But your best bet is to get another stock i5 750 cooler and just put its fan onto your existing heatsink, that way you don't have to uninstall your heatsink. Though I'm not really sure you can easily separate the fan from the heatsink - you'd need to check on that.

magmag. The fan will stop almost immediately if you spin it by hand, as it uses permanent magnets inside to reduce heat & power usage.

The main reason for replacing a fan that still works is if it's very noisy, which indicates a dry bearing & generally speaking it cannot be successfully lubricated.

If your fan runs normally & is quiet, leave it alone.

It's quite in normal days but on hot days, the fan is mostly changing between high and low speed rotation & it becomes noisy.

For the rotation of the fan, back in the days, when I blow dust from the fan, it used to rotate for a while after I stop the blower. Now the fan stops kinda immediately after finishing blowing air so I feel it has a dry bearing. I'm assuming that the oil has dried since I assembled my machine from mid 2010 (but it's not running for 24/7).

The Processor Fan will rev up if the CPU thinks the Processor gets hotter than normal. I'd rather buy new fan than lubricate it because you will destroy that fan.

I tried as you said, blowing the fan, to see where any difference could be.

I have a spare Foxconn Intel cpu fan that hasnt been used for nearly the past three years. So I tried blowing air over the blades to see where it would get me.

I must say that firstly I gave my puff a short throaty huff kind of blow - as you would to blow dust - and the fan blades rolled over only a few ticks then halted abruptly and swayed side to side momentarily before reaching a complete stand still.

After repeated efforts to get the thing to rotate on its own for a while, I then decided to blow a chesty lung of air, and it did indeed rotate at speed for a good 2 - 3 seconds, before the blades abruptly halted and swayed side to side as the fan came to a halt; you have to blow at the right place, like over the fan blades to the right side or to the left side, because otherwise, if you blow in the centre, then the fan doesnt move much and its rotational mechanism looks quite stiff also.

So my conclusion is that you are right, the fan blades on a cpu do rotate for a while if you put enough 'puff into your huff' (?), AND blow air across the blades from above in the right place, because if you blow merely 2 cm away from the right place, then the mechanism is full of inertia and abrupt in motion again.
