i'm a tx 1221 user...for about 1.5 years my laptop kept overheating with temperatures above 70 degrees...somehow i survived...last month it finally died so i had to replace mobo for rm 500 at my cousin's repair shop...complete service n cleaned inside out...now its working like magic...no more overheating no more loud fan noises...no more lag in games that i play...i kinda like my tx1 now...hopefully it will last for at least 1.5 years more...^^
