So basically i was playing path of exile and suddenly my fan started to rattle and its been doing that for 5 days now (I cant really send it to be repaired at the moment since i use it for school) so my question is can this do any damage if i dont repair it within a month or should i repair it immediately (Since i cant repair it myself since that will break the guarantee)

Rattling noise of any kind is a warning that something is wrong. Get this taken care of as soon as possible. Do not wait. (It might be some foreign object that is interfering with the fan blades).
Cleaning the laptop with a can of compressed air would help. Take the rear cover off and do this very carefully.

There are two types of fans.
Cheaper quality fans tend to use what we call a copper bush, they are know to wear out quickly and once the bush becomes miss shaped the fan starts making a buzzing sound, with lots of vibration. This is because the inside of the bush becomes worn away and becomes slightly elliptical in shape.
Other than a perfect circular shape.
So the inner pin connected to the fan blade assembly begins to rub or wobble around in the elliptic worn shape of the copper bush center.
Just simply by a whole new unit if the case.
With the type of bearing used these fans should simply be replaced with a whole new unit, or fan.
The second type of fan does use two bearings, and lasts a lot longer, in fact about five times longer than the other solution.
So if the fan is only a year or more old then it likely has a cheaper fan based on a copper bush.
The bearings in more expensive fans are in fact sealed and look like this.

You can take the fan assembly apart and lubricate with WD 40 if the bearing type above.
