I just ordered a t9600 from ebay for my g51vx-rx05 asus gaming laptop. when i opened the package, the seller had held the chip onto a plastic piece with masking tape (touching the topside of the cpu chip and heatsink) and thermal paste was caked all around the small metal heatsink on the green chip. i have 70% isopropyl rubbing alcohol and cotton swabs. is it ok to use this to clean the caked on thermal paste that oozed onto the green chip? or should i just clean the heatsink and leave the caked thermal paste on green ship?
