it's simple
1) measure ur laptop for buying acrylic, find out ur notebook heat area so tht ur fan is designed at the heat area
2) choose the amount of fan n size u wan (i take 12cm fan as it's silent n has great airflow)
3) buy adapter, either 500mAH, 800mAH or 1000mAH, the higher the greater ur fan will run when u full load it
4) take ur fan n goto those shop which sells arcylic (i used 2.5mm thick arcylic, 3mm oso can), tell him ur idea n give him the fan for reference
5) make sure u do not miss out the hole for screws when the shop makes the blowhole, every blowhole n screw hole is done by the seller
6) now arcylic kaodim, go buy the red rubber tube (any size as long as taller than the fan) n screw w nuts for the red rubber tube
7) screw them all, cut ur fan n adapter wire, connect it to the fan n remember to use tape to wrap the joint part, n u r done
normally shops which sells arcylic are those DIY shops right? they'd also be able to cut the blowhole for me as well right? cause i have no idea how to make a blowhole to fit my fans. if i'm planning to use 2 12cm fan one at bottom right the other at upper left of the board, how much of an adapter capacity should i be using?
