Can this be a problem? Because i installed a new cooler for my CPU and i heard people say not more than a peasize... and if this is true, I over-did it by a long shot... Can too much thermal paste hinder performance/temperatures? If so, is it a noticable difference?

Yes it can if you put to much on the processor temps could be varied by 10c or more compared to if you put on theright amount.

Wondering if i did it right drives me insane, Ive re-mounted at least 10 times now, and im still thinking about re doing it.

for c2d the best i found is the razor blade method to the base of the HeatSink.

Durring all this I've also learned that not enough is far worse than too much. (heat wize)

Depending on the condition of your IHS, concave or not, this is not true.
Less is almost always better.

If you put too much in, it's just gonna end up getting squashed out the sides.

Once of my friend's HS and CPU was smeared with thermal paste that it seep out and went all over the CPU socket and motherboard, the store he took it to to build it seems to have not idea how to apply it

if it oozes out all over the place that might not be very good cause some of it is conductive.

This is why I recommend Zalman's STG-1 thermal compound. You just brush it on and it works about as good as Arctic Silver.

Yes but the thicker it is, the harder it is for the heat to be transferred, aka resistance. That is why people say to spread it out as thin as possible.

Ya thinest is the best, but i think with too much at least your getting complete contact, not enough and you could end up with only a tiny contact point and alot of air.

If both your IHS and HS are flat, there is practically no need for TiP other then to fill the microscopic gaps/grooves which is why just hazing the surfaces with TiP offers great thermal performance.

I use the finger in the inverted plastic bag and latex glove.

but since the thermalright ultra 120 extreme base wasn't flat, I couldn't have used ac5 or zm-stg1 because theey bleed easily. So I used the thermalrights paste, and the finger method wouldn't work I had to get a brush from the zm-stg1 cleaned it thoroughly, I still have to lap my heatsink though, which will take quite a while, not to mention the driving time to get sand paper.

When I was using the finger method with thethermalright paste it kept coming off the cpu, and going everywhere on my motherboard.... I had to get 5 q tips to clean the motherboard...

I just put about a blob of about 1.5mm x 1.5mm x 1.5mm

I find finger the bag method a good prerequisite to razor blade method.

Alright thanks for the help guys. I just reapplied it and noticed that my temperature went down 2-3 degrees :)
