Hey guys

Recently re seated my heatsink and cleaned the cpu + heatsink base with "Akasa Tim Clean" then applied some artic silver 5.

My idle temps were 33-35 with the old original paste, now its 38-40 with the new paste.

I applied 3 lines of paste across the top of the cpu because the original paste covered the entire bottom of the heatsink.

However the Artic silver website says to apply to the middle of the cpu the size of a grain of rice, it also says it can take up to 200 hours to reach optimum temps.

I would say I have had my pc on for around 15 hours, with 10 or so shut downs.

So is the paste just needing to "bed in" further? or have I applied too much??

Don't think you've applied to much. You might just find that you are a couple of degrees higher because of the humidity difference from your old temps to your new temps. Also AS5 does take about 200 hours to reach it's best cooling, so probably another couple of degrees of there and you're about the same.

I did exactly the same the day before yesterday. Took heat sink off and it was caked in the stuff! So I thought it best to apply less and therefore went for the "one line down the middle and two either side" approach. Temps stayed the same, however there is meant to be a 200 hour bedding in where you "should" get 2-3 degree temp drops according to the website. So I'd be interested to know what other methods people have used and how much they have used? :D

Way too much.

What you are trying to do is apply just enough paste to fill in any microscopic crevices in the IHS and HS - not make a metal sandwhich. Too much paste will act as an insulator and not a conductor. Clean it off and apply a very thin strip down the middle as per AS5 instructions.
