MX-4 paste vs AS5.. which is the one where its safe if it touches the components on the mobo? also can someone tell me what positive pressure is?

Hi

I'm still waiting for my z77 sabertooth to be delivered and I was wondering which of those two pastes is safe if it gets on components. Isn't it MX-4 where if it comes off the side of the heatsink it won't damage the components?

Also how do I get positive pressure in my HAF X?

I have h100 in push pull w/ 4 cougar vortex, two 200mm top fans, 230mm front, 140mm front bay, 140mm back, 200mm side.

pls help!

yeah mx4 is non conductive. arctic silver is...

Neither of them are conductive. Anybody saying AS5 is wrong.

Arctic Silver stated themselves it wasn't.

You will be fine if they touch other components.

on as5 website it says it can bridge two connections if it gets on it and ruin them frown.gif

If there is enough of it, yes. It could even happen with too much dust inside a case.

You don't want to apply too much to your CPU anyway. With any thermal paste.

As for your positive pressure issue. Basically there is more airflow going into the case that what is being let out.

You could do this by calculating the CFM of the intake fans versus the CFM on the exhaust fans.

I think the point is that it is capable of inducing a capacitive discharge, vs lets say MX-4 that wont.
dust can yes, but so can air rolleyes.gif AS5 has a much much higher chance of doing so.

That is because it is slightly capacitive, not because it is conductive, It is not conductive.

I have used and like both. Never had an issues with Arctic Silver. I have MX-4 on my CPU now, there was no real difference after the change was made. Temps are pretty much the same.

Not discharge, where did you get that?

To get positive pressure its very easy. make the top of your case exhaust, make everything else intake. Boom. Heat rises, positive pressure, have a nice day.

As to the TIMs, either is fine. MX-4 will yield slightly lower temps, and also doesn't come with a 200 hour cure time.
