Had a problem with my brother's processor fan screaming bad, so ordered a new one (Intel) and it comes with the shroud, heatsink and fan (I'm assuming it's all together when I get it). And ordered thermal paste as well.
Will have to remove the old stuff and apply new paste as well. So if there's a tried and true method of cleaning and applying it would be greatly appreciated.
My nephew said I could use 409 on cleaning it and have looked at a few videos online on applying the new paste, but those videos are different and wanted to ask the experts here. One guy said to use a business card to spread the paste over the whole processor, where as another one said to just put a BB-size dab on it and then put the heat-sink on and it should be good to go.
