help... i bought very powerful 120mm fans and the air flow is crazy...
and i bought 3...
their demissons are 120mm x 120mm x 25mm
i install them under the CM notepal u3 and the airflow is ***king imba
bottom was no enough air to suck and cant get full air flow cus the holes blocked the air flow cus the air flow too large...

damn crazy... u might dun belive the air will reflect from the laptop bottom case and return to the fan...
so it ***king noisy...

I've wired up 3x 120mm fans to adapter...
I have CM Notepal U3 and 3x 120mm fans...
any suguessions for me to get nice air flow and good perfomance?

I tried to do the case with box but the fan is ***king heavy...

its annoying i really don't know i am happy or angry...lmao

Attached thumbnail(s)

The old fan i used for my modem cooler, and i used 5V usb adapter to power up it so it won't noisy...

I get another one









Is it powerful you should know... Aluminium Mesh
The power adapter i get from my old modem,\
now days all modem power adapter is 12v, hard to find 5v

Extremely silent, only can hear airflow sound

Added on May 14, 2011, 3:46 pmI strongly recommend to clean your laptop's heat sink before you get a cooler... Also change its Thermal Paste to Arctic Silver 5 ,Tuniq TX4, Arctic MX-4 etc.
Works great for me, btw i don't need a laptop cooler anymore for now, thats a gift for my sister's birthday...

yea...i am so happy my laptop's heat sink is hot for now...and the temperature is balanced... unlike before only CPU and GPU part is hot like boil water...now all bottom parts are warm... so with cooler will be perfect

thanks for support
long time no come here oledi
i sold my fan cus my sis bought a new pc
i install in her pc and damn noisy so i sold it lol
cus install on U3 it cannot suck 100% air that the fan can suck(mean fan can push 90cfm and it only able to push about 30cfm cus too near table)
and it make my hand very cold at night oso
since my laptop change thermal greese and clean up all dust it wont hot... so just make my u3 become backplate
no do worklog cus the wire keep loose duno how to wrap them together

and the CM fan static pressure is **** low

for that diy cannot lah postage here there around rm20 already

the wire should be like this

the power 5v or 12v oso can depend on speed u wan
usb is 5V but beware fan power dont over 0.5A or ur usb will burn
how to connect to usb can google for usb pins

fan recommentation just dun get the cm 90cfm it really suck imo
if u wan mod u can make it taller to let it suck air but still dun use that cm 90cfm the static pressure too low
perfect if you have something like 230mmx10mm fan, you made a zalman RM200+ suck ass cooler

more question can pm me
