I need to re-apply a fresh new layer of thermal paste between my CPU and heat sink (I'll be cleaning off the old layer with isoproply alcohol). It's been several years before I last did it. How much paste do I need to put on? The CPU is an old Intel P4 3.2 GHz Northwood (old but it still does what I need this particular PC for). Articles I read about applying thermal paste are very vague, they just say not too little (or it won't be enough to do the work) and ot too much (or it'll insulate rather than aid in cooling). Some diagrams on the Net show "this is too much" but there's never a picture showing the right amount. The paste I'm using is Akasa 445, but I don't think the type of paste matters regarding the amount needed. If I was to put a blob of the paste on the CPU before spreading it, how big should this blob be so I know I've put on enough? Some reports say the size of a grain of rice whereas others recommend the size of a pea, which is a big difference. Thanks in advance.
