just put on some silver compound then had to redo it - i got some residue from the silver compound on the surrounding chips around the core. i cleaned out as much as i could with soft cloth but could only get so much off. comp hasnt been turned on for more than 30 minutes since i put in so i dont think i have damaged anything. am i put the cpu at risk or should i just forget about it. also what should i use to clean it - soft cloth or something else. much thanks.
