    Wait
    Do I understand this right?
    I have a ranger with stock fans at 1.66 cpu/ 1,74 gpu/ cfm, 5v 0,5A
    This thing has 9*more cfm and its plug and play?
    It says 1A - any concern?

    It's currently running. The 4930mx also died in the motherboard socket but my backup 4700mq still works.

    It's a bare minimum ranger currently. But I'll be modding the storage shortly so I can be rid of the precision. Total of 8 drives in the ranger.

    Well, I have it in.
    Seems better than the stock one.
    Is there one like this for GPU?
    Or can this one be transplanted to the gpu housing?

    For the gpu we use the M17x r3 fan which has 11.2 cfm iirc

    You won't be able to max it without cutting the pwm wire. Some of us made a physical switch so we can go back to being silent when we want to.

    yes, Ive seen that.
    I was just wandering, shouldnt the higher cfm give the better cooling result at the same, non maxedout speeds?

    No it tends to give higher Temps avg because the EC was designed with one fan in mind.

    At least this was was happened when I did the same mod to my old y510p before it kicked the bucket.

    That being said, max fan yielded much better results. I was cooling the 780m during gaming it never breached 56c. This was while playing siege, one of the only games I play on the daily that's relevant. Everything else is older for the most part (mass effect trilogy)

    Been trying to get my hands on THPDJ but its impossible.
    The listings are fake.
    So I got one of our good friend Cici since he eventualy listed GPU turbofan.
    I got one for the CPU before and although I dont use HWinfo fan control and did not (yet) cut PWM wire it works better than the stock one.
    Originally, stock ones went to 3900/3300 rpm (CPU/GPU) max.
    Ive seen this turbo go at 4700 but just for a very short time, but its new, better max.
    So when I got the GPU turbofan (It looked weird he listed spec table and it was the exact same one as for the CPU fan) I noticed that one of the wires on the small fan board was lose, like it was poorly soldered so it fell out. I went on resoldering it and put it in. Then I noticed that when you insert the conector, those wire ends that stick into the conector tend to pull out since they are not glued like the stock one. Well, that would probably short those wires so I made an effort to push them back in.
    All well.
    But no, the temps were worse then with the stock one.
    So I contacted our good friend and he said, yes, he "cut" the pwm wire!?
    Then I too desoldered the same wire but nothing happened, no fullthrotle max speed as I was expecting to see.
    Anyhow, I am all for making that switch and have it done with, Im waiting on some Ram so I dont have to pull the thing apart more than needed.
    I was looking for some really, really small switches though. As I can see, they could fit the kensington lock and need just a small cut to fit the wire trough. My idea is to make the minimum of dremmeling as possible.
    Oh, and heres my U3 mod done yesterday=)
