Anyone can tell me if the small rubber piece next to the fan is for the vibration of the fan ? because mine lose the adhesive tape and it moves when i touch it, and if it loose maybe that can be the problem? i didn't test it because i don't want to open the laptop only for that...

With the keyboard assembly i think is the problem of the vibration, because i don't feel vibrations around the fan without the keyboard, im going to record a video showing how it looks...also the left side of the palmrest in the coupling is a little bit propped up but i don't think thats the problem.

Im going to try without the keyboard, and i tell you what happend...

bump. Someone who have dissasembly the whole laptop can help me ? M14x R2.

The new bios A12 fix that problem. Download from here : Driver Details | Dell US

i didn't understand the first part " tighten the screws of heatsink and fan only "over cross" not Clockwise or vice versa ", i don't know what do you mean about " Over Cross "my english is bad too, i speak spanish acctually. Im going to do this : take out the fan, and align the holes of the fan to the heatsink and motherboard and paste the tape again, place the screws not to tight, only secure. and then the motherboard the same place the screws not to tight. About the palm rest on the left side is a little bit propped up so maybe something pushing up that im going to see on the next fan " replace ". The rubber from the air flow doesn't have that glue because i take it out a lot of times..doesn't matter that ? thx for your help! any tips are welcome!

I replaced it with a new fan and heatsink, and the problem persist, i don't know if it a problem of the air flow passing inside the fan thats provoke that vibration, i tryed to adjust the screw and loose of the fan andand still persist the problem, also i tryed to loose the palmrest a little bit, but nothing change, don't know if the position of the keyboard or someting beetween the keyboard and the fan...well nothing works...

yeah is strange...i checked a lot of times...but well..maybe i'm going to check again...

well i try again untightening the screws but still persisting the vibration...i can only feel it when the fan goes faster...if the fan is on low rpm i don't feel it..maybe the keyboard or the palm rest assembly is a little bit loose but really i don't know..the screws are secure... after a minutes trying the fan i opened again the laptop and completly remove again the fan and put it back again tightening the screws of the fan again but is the same...i dont know if i can try it before assasembly again the whole laptop...or its dangerous doing that...i have al the cloth anti static and everything for the secure of the components of the laptop... and i dont know if that vibration can harm the components of the laptop...its not a big vibration...but you can feel it and its annoying... if you know something or someone reply my! I repaste with ic diamond 24 when i changed the fan for the new one, so im trying to solve that without taking apart the heatsink...because i read about this paste that cannot remove easly and can damage the diode from the chips... The laptop i bought it in Mexico and i live in Argentina ( here doesn't sell Alienware ) so i think they have to send my laptop to Mexico and i don't know for how much time and the cost of that.. for that reason i want to do it by myself... :S Edit : well i take out the fan, and i blow air with compressed air and the vibration i think is the blades spining... i test the new one and the old one and vibrate mildly both...i have a fan of an alienware m14x r1 and i test it too and that one doesn't vibrate or something when i blow it with compressed air...i think my both fan from the r2 are bad...( i don't know why because the new one had the security tape and everything..so is new..) but well..i don't know...i have warranty but i don't know if it gonna cover me...you know what i mean... i'm frustrated a little bit...

i will try doing that..another thing is that the back of the keyboard had the mark powder ( circle ) of the cooler , maybe is touching the keyboard ? for the moment im going to untighten the screws a little bit... you mean only the 3 screws of the fan right ? thx for your help I appreciate that..

Hi guys again, well i bought a new cooler from a internet website, today i change the old cooler for the new one ( had the secure stick on the tape ) and the problem persist, i feel the same vibration on the keyboard with my hands when i playing... don't know what is wrong really, that happend the first time that i repaste the laptop...i don't know what to check because the fan is new and secure with the 3 screws... i live in argentina and i don't know how is the support here, because they don't sell alienware in my country...so i do the things by my own... I have a lot of years repairing computers and i have a certificate ( microsoft ) of that on my college...but i don't know what to do to repair that, i think is something easy but i can't find the solution... if someone know something about that and want to help me, i appreciate that! Thx for your time!

Ok Brian! i will do that then, thx for all your help

I test another thing today, i take the cover of the back of the lap, i run prime 95 ( to make the fan spin faster ) when the vibration start y push with my finger the fan ( from behind ) and the vibration stop considerably, but don't know to solve it. Maybe is the vibration between the fan and the heatsink or dont know what.

Hi Brian, the fan keep running faster ( like on the video ) before i used intense aplications during long time of use, i restart the laptop and still the same, since i bought the lap was the same, but that not bother me really ( i think is the sensor of the pch temp is high and thats why the fan keep runing ). Well Brian if you think the sound is normal i don't know what to do about the vibration, the lap is in warranty, it doesn't matter if i dissamble before to repaste right ? if the fan looks normal ( without nothing broken ) this keep my warranty valid to replace them ? Thanks for your assistance Brian!
