Windows 7: Used way too much thermal paste

Used way too much thermal paste

This isn't that important, all it is is that I'm worried.
It was my first time round putting thermal paste onto a cpu, and i sort of used an entire 3.5g syringe of arctic silver 5 underneath a zalman9700.

Yes some did come over the sides, wiped it off, I'm guessing there is a layer inbetween the cpu and the fan now. (maybe even an air bubble)

Temps on a q6600@ 2.8GHZ, fan RPM 1500, 28C per core, 42C on load.
Since arctic silver takes 200 hours to set in, does anyone know what the effects be during that time and after ?

Can anyone estimate how much hotter the temperatures are (compared to if I didn't smother the cpu in paste) ?
And really is there any risks or future problems that could happen ?

Overall nothing seems to be too problematic, but then again, there might be, thats why I'm asking.

Yeah, that's not too good there.

You only need a very thin layer. As long as it covers, thinner the better.

Anything more will cause unnecessary heat. A whole syringe could cause cpu failure from too much heat, in the future.

It's only been there for a day or two, I have some thermal remover if its possibly to actually take the fan off and scoop a little out, I guess I can check, but I don't know If it will have solidified already. (that would possibly be during the 200 hours..)

You can always remove the paste no matter how long. Use a dry paper towel and q-tips. Be very gentle.

Thanks for the help", I'll be sorting this out tomorrow.

Look here for how to, direct from Arctic Silver:

For a quad core, here is the pic of what you should have done. The red line represents the line of paste:

It's worth bearing in mind that Artic Ceramiqué does not set quite as hard as Artic Silver, yet offers excellent thermal conductance - and it's also easier to squeeze from the syringe.

If you get excess thermal grease onto electrical contacts you should gently and very carefully clean it off with a little rubbing alcohol, since it has some electrical conductivity and capacitance properties.

Overall, since the fan is mounted on a bracket, when the fan was tightened onto the cpu, it squashed out the excess compound, basically there is a very fine layer in there now, which is in a big square across the entire cpu, although its supposed to be a nice circle, i doubt this will make too much a serious problem.

there was actually loads of excess at the sides, which i cleaned off, although now, temperatures are now 1 Celsius higher than they were before, but I guess I'm just imagining this, or thats due to any air which is now in the solvent.

Atleast I and maybe some other on looker hath learned =p
