if you guys wanna find a hobby shop, you can go to the one i go to in damansara jaya, atria shoping center.. nearby KDU college, sunday morning to evening we have pratice sessions. people there are really friendly, come have some fun.
Recently i've read up some articles, found out a good IC SHOULD not only lower down the temp but also to improve flow which shld be the factor if we ever wanna change it.
