How much you but that aluminium netting

u mean buy it is ??? 1 meter x 1 meter = RM5
maybe at ur place different price lor.....

What is the netting for exactly?

what do u mean ??
if u mean why put the net at the fan, so the answer to capture dust i think....
coz i read one article dont know where, about how the net can minimize dust going inside pc

nice mod
where connect the fan power to

to fan controller, using 2 x 3pin extension cable... haha so long

I think he meant what for like, for mosquito maybe?

bro i have an idea. why dont you remove the LAN LED. than using another LED, you can tap the power from there and have a nice blinking effect on the fan while you're surfing.....

Yo shah, since ure 1 of the electronics experts here. Just wanna ask bout those modem LEDS. They're running on 5V or 12V? I wanna solder sum wires in parallel to the LED n power sum blue LEDs n a 40mm fan for my acrylic modem.

i think so hehehe

yeah good idea

yeah i also wanna know power for that led......???
but i think lower than that, maybe 2v only la

the modem LED should be running at around ~2V only. you can connect another LED in parallel but if you find that the LED became too dim, you'll have to remove the original modem LED. for powering your fan, i think most modem runs from a 9V adaptor. just tap the power directly from the adaptor connector on your modem boards. but please make sure the adaptor is DC. i've seen a modem use an AC adaptor with the bridge diode inside the modem.

Ya. I happen to haf the silly AC adaptor.

now now, dont cry yet...there's still a way to do it. the LED mod can be done just fine. the fan will be a bit tricky. you need to find the bridge diode output and tap the power for your fan from there. very easy to do. btw what is the voltage output of your AC adaptor? maybe i can help you if you have a high res picture of the modem boards

Take a look at my thread. C if u can c the pix clear enuf. Thanks for the help.

u can try to mod the fan draws the power from usb port(5v)

wow....

actually i already voided my warranty...

i opened up the casing 2 weeks after i got my modem,

but i managed to ensure the void seal looking like it was not tampered with....

i dunt know, since the modem is given by tmnut... and it is still new, but it is REally HOT !! crazy Zte Modem....

anyways...

maybe i can just find a Zte Modem which is spoilt and replace the casing.... 1 casing at stock, the other one i can mess around with

actually i found out that blue n white led operated on 3v-4v.....
so in this case, if gonna use the LAN led as source, i think can use red, yellow or green coz this led will function at 2v only

so what do u think when u look this....
can the fan connect direct to it ???
or must add resistor ????
my modem adaptor output = 18VAC......
so whats ur idea ???


that a good idea, thanks

ha ha going to mod ur modem is it ?....
so dont forget to show it later !!!

erm.... modding it soon...

currently this is how it looks like....




A 120mm fan sucking air from on top of the casing.. ehehe....

ok already added LED for fan taken power from LAN LED.....
so let see...


cutting the LAN LED and connect it with resistor....
not good solder n cutting actually


all done n light it up....


zooming in......


in dark action....


i connect the led using parallel...
i found out that the led not as bright as i expected........
i think coz the power for LAN led is only 2v.....
but if only using 1 led, its so bright....
so now when i surf, the led also blinking

so everyone plz give ur idea n suggestion on this mod....
hope to fix the LED bright n also the power for fan

Power for the fan:

that rounded thing is not bridge diode look at the picture below (ianho's modem). see those 2 caps that i pointed at. one of them is the power filter caps and you can tap the power for your fan from the +ve leg of that cap. just measure the voltage and the one that have the closest voltage to the output of your adaptor is the one. i think its the cap that is closest to your adaptor port.

now if the voltage is higher than 12V, you could use LM7812. this voltage regulator will reduce the voltage to 12V.

LED:

what is the value of the resistor? why dont u try connecting the LED without a resistor.
