it isn't really that difficult - you just need some cleaning alcohol to clean the processors and a high quality thermal paste (for example the Arctic Cooling MX-2 or MX-3 ) for ~$10
gilksys ylod youtube guide can show you how to do it, but because you don't have a ylod you don't need to (or better _shouldn't_) heat/reflow the chips, so there are less steps to follow
