I think I am experiencing the cpu overheating problem as stated in this post

http://en.community.dell.com/owners-club/alienware/f/3746/t/19516339.aspx

If I want to clean it myself, what things I need? thermal paste? and other materials ?

Please give me a correct name, so I can search for them.

If I want to replace the cpu cooler,  what type of cooler will be best fit for Aurora R4 (desktop)?

this desktop is mainly for hardcore gaming.

Thank you very much!!

Please help.
