    What a good idea!

    Uncharacteristically, I'm going for this straight away, but for some reason amazon.de don't want to send this to Belgium so am forced to hunt around.

    I notice that Cooltek do a thinner (4010 = 1cm instead of 2cm (4020) thick) fan: any reason not to go for that since there's going to be an abundance of airflow anyway?

    EDIT: Cooltek fans are 12v but the BB is 24v. How did you deal with that?

    How about these: http://www.digikey.be/short/340cm7

    I have two of those at home not tested yet. They have about the same amount of flow as the original fans but a lot less noise. At least on paper.

    I suspect 'on paper' is the critical bit here. I have yet to meet any fan made by Delta that could remotely be described as quiet, but I'm prepared to be wrong!

    I might try this mod with some Noctua fans as they make some very quiet, albeit pricey fans. They do a 40x10mm one, it's 12V but that should just be a matter of switching the jumper on the RUMBA to set the fan output to 12V.

    It should fit with most 40mm fans, the screw holes are 6mm deep.

    I thought the hotend fan is already set to 12V on the RUMBA, I didn't check it, I just soldered a small XT30 plug and socket plugged it in and it worked so I didn't bother checking the voltage.

    It is significantly less noisy than the stock one (which had also vibration noise) and with the XT30 I can swap it out in seconds.

    I got these: http://www.aliexpress.com/item/10pc...lugs-for-RC-Lipo-Battery-FPV/32443401570.html
    There is also a three pole version: http://www.aliexpress.com/item/Bras...th-Sheath-Female-Male-For-Rc/32657892082.html

    @Sarah Nicholson I really like the look of the Noctua (esp. small motor profile) but it's unbelievably 160g http://noctua.at/media/blfa_files/infosheet/noctua_nf_a4x10_flx_datasheet_en.pdf

    versus: http://www.cooltek.de/ArboroPDFCreatorSW4?id=110

    @CHP oddly, seeing your cute furry profile picture at the top of the thread, I initially mistook you for Sarah! You might want to check your voltage to prolong the life of the fan. And get some extra quietness for free.

    Nice dual pin RC connectors, though they're more for the heater cartridge IMHO.

    Ouch, I didn't notice the weight. Yep, that pretty much rules that out. :-(

    @R Design I'll check the voltage today.

    I'm using XT90 on my bike since the Anderson PowerPole melted after a month and I'm very happy with them. So I ordered some XT30 and was surprised how tiny they are. Also they are very easy to solder and plugging/unplugging is very smooth.

    I think I'll use them for most stuff.

    PS: It's feathers. But you are the first to say cute. Most people say it looks ugly.

    I have "fond" memories of a FOP38 cpu cooler with black delta fan maaaany years ago. One floor down my parents asked me what is that whining sound from up stairs. So I know they Deltas can make sound. But I bet they also can make more silent fans :D
