Thermal cleaning compound? Can't I just clean the old thermal paste with some isopropyl alcohol? Also thanks for all the answers guys
Yes you can. Long time builders recommend using the actual product when it comes to cleaning the heatsink but I usually don't. Unless using isopropyl alcohold will lead to an early death for my CPUs or make it perform drastically worse I don't see the point in buying thermal cleaning compound. Many people already have Isopropyl alcohol at home (not that expensive) or at least what I would think. Not all used heatsinks have the old thermal paste still on the heatsink.
A used heatsink, like he said he could be getting, will most definitely have in on there unless his brother already cleaned it with alchohol. To me, if you have Isopropyl on hand, I would use that. Otherwise its best to buy the cleaning solution. In addition, you have to wipe the surface with something that won't leave traces behind. Coffee filters do the job.
