I recently put together my PC that isn't working I have to take it apart to return the piece that's not working I don't have any alcohol to clean the thermal paste off the CPU would it be a big problem if I kept the CPU in it's box with the thermal paste on and then clean it in a few days when I have the alcohol? What about the CPU Cooler can I keep that with thermal paste on? It arrived with a sticker on the part to put on the CPU I don't have that any more would that make a difference?
