So, I've just ordered all the bits for my new PC which should be delivered tomorrow. However, I totally forgot about the thermal paste for the CPU/Heatsink. Now, I haven't built a PC for over 4 years and am not up to date with the latest stuff. Last time I user Arctic Silver and spread a small amount over the CPU die (Athlon 64) and then slapped the heatsink on. After doing some research, seems like Arctic Silver 5 might be the way forward. Is this the case, or are there some better products available? I also checked out some application methods on Youtube and a lot of them show that the paste needs to be spread over the entire CPU using a finder?!? Is this right? Thanks in advance. PS. The CPU is an i720 and I'm planning to use the stock heatsink that comes with it.
