[M17X R2] CPU FAN Upgrade

Hi,

I have made an other thread about that on notebookreview, that might interesset some people so i post it here too.

Some of you know that the m17x r3/r4 cpu fan can be upgraded with an m14xr2 fan, 2.2 Cfm vs 10.1 Cfm ! I wanna try that too on my m17x r2.

The problem is the wiring of the r2 is a bit different, there are 5 wire for the stock fan and only 4 on the m14x, but the m15x has five wire and the last wired is solder on the ground wire so ...

I have ordered an m15x fan, cut its wire and soldered it on the m14x fan, be careful , the wiring pinout is not the same on the m15x and m14x .

m15x :

red +5v / black ground / yellow rpm / blue pwm / green soldered to ground

m14x :

black with red dot +5v / black with yellow dot rpm / black with white dot pwm / black with no dot ground

So it work ! And It run at 4500 rpm and not 4000 rpm like the stock one, but its way smaller and the airflow goes every where. Anyway my i7 920xm stay at 70 ° under wprime @8 thread and 3.35 Ghz.

Now my idea is to use the stock fan frame, i will cut off the rotor and keep the frame as an air duc, a new stock fan is comming, i don't want to destroy mine without any spare as i need my laptop to work.

I think this fan is way more powerfull than the stock one, i will keep this thread updated with the result.
