May be a little bit of a silly question but I'm thinking of upgrading my motherboard although keeping the same CPU, I'm not exactly sure what to do with reapplying thermal paste. Do I need to remove existing paste? If so what with?
Any advice would be great!
Thanks

Yes you need to remove the remaining thermal paste from the old application. If you have a coffee filter that would be best as it doesn't leave fibers behind. If you don't have that you could use paper towel. You'll also want to make sure to use some 99% isopropyl alcohol. Apply the alcohol to the coffee filter or paper towel lightly and wipe the cpu clean. Be careful not to have alcohol go everywhere also not to leave fibers behind.

Yes you have to clean all the paste. Use a little bit of rubbing alcohol and tissue. When you apply the paste again, apply it on top of the CPU. About the size of a the Capital letter O on your keyboard. You'll read about putting a small dot size, but my small might be big to you. But keyboards are standard. :p haha

Yes you need to remove the old paste, wipe the cpu clean, wipe the heatsink clean, the reapply the paste. Use the highest % rubbing alcohol you can find(91%) or Everclear is even better if you have it in your liquor cabinet (or with your oven cleaning stuff) lol
 


anything 70% or higher will be fine, don't run to the store just for 99% lol. If you need to buy alcohol anyways get 91%+. As for getting it off you want something that wont scratch a bunch, or leave any little fibers behind as they are bad for heat dissipation to the CPU cooler. When re applying make sure not too add too much, this is one of those 'less is more' kinda deals. You want the thinnest possible application, with full coverage and no bubbles. More paste will actually hinder performance. There are plenty of tuts on how to apply thermal paste, just make sure when you clean not to get it on the other components or the socket/bottom of chip. (I clean from the outside in as to not accidently wipe onto the mobo).
