    Ah the good buddies of the Bosnians.

    I will try and get a pile of fans up onto eBay. I think the international shipping does Croatia.

    Had some used THPDJ laying around, am selling them on a German marketplace at the moment. If you are interested I can check for shipping costs.

    Well, I'm sorry I didn't ask earlier...
    I'm in the process of returning the GPU fan to mr cicichen along with one CPU fan since I had two of those.
    I'm on a tight budget and these things add up and I've got some hurdles ahead too.
    So you both have genuine r4 fan 11.4 cfm, model THPDJ?
    I would really rather have one of those in, hope cicichen don't mind.
    How do we go about this?
    Can you pm me the link or something?
    Germany is close so I presume the shipping would be lower and faster but anyhow..

    So finaly the genuine THPDJ arrived!
    I have cut the wire (blue) and did the same to one of those turbofans for CPU and put them in.
    ANd the difference is HUGE!
    CPU fan goes to 5700 and the GPU one to 4500 rpm. They are noisy and irritating when non stop at 100% but coupled with U3 mod I have idle cpu at 26c, gaming (a game is my benchmark) I went from 50 to 40c on cpu and from 60 to 50 on gpu. Thats crazy!
    Can it get any better?
    Sure! Im preparing to go full copper cpu heatsink, change to much better thermal pads and lm.
    And after this instalation i went back to have a look at that gpu fan that I got earlier...and whadyaknow...the guy cut the wrong wire! Thats in the picture, the colored wires are THPDJ fan and you have to cut the BLUE wire, his are all black and he cut the wrong one.
    Anyhow, glad what the pwm wire cut does but have to get that all back until I find the right switch and time to put it in properly. This is way too loud to be something constantly going on.

    Yeah yellow is just the rpm signal.

    One fan says 11cfm @500mA and the other says 10cfm @ 1A

    I wonder what the max current of that fan connector really is.

    One other thing I will add to this conversation is what I have noticed screwing with this unscrewing fans business...is when you do that a lot (and admit, most of us do that far more than normal) the threads of the screws eat their way to the aluminum casing, making some hard to see bits, which can go places and do a lot of damage!
    Vacuum an check, then check again, that's what I would advise.

    I wouldn't vacuum, can generate static which isn't as world ending as it used to be but still a healthy precaution.

    I generally take air cans to the components and spray rinse the chassis.
