All the above pastes you mention are very good, your already using a pretty high end paste in mx4. The only conventional paste that might give you a further temp drop is ic diamond. It wont be a big drop tbh. The next level after that is coolaboratory liquid ultra/pro. Link to ultra below.

This stuff is on a whole different level from normal pastes. The cons are, it stains heatsink bases, and cpu surfaces. It is conductive, it is very different to apply than other pastes. It eats aluminium parts, not an issue as cooler bases arent made of aluminium. The pro is, it produces far better temps than any conventional paste could ever do.
Ic diamond doesnt stain a standard cpu heat spreader, the stain that liquid ultra/pro leaves can be cleaned of with a good metal polish cleaning solution. Application wise, ic diamond is different from liquid pro/ultra, and yes it's safer. With diamond, you put a small rice grain size amount of paste on the cpu. Then place the cooler on top. With liquid pro/ultra, you use a tiny amount of the paste, then spread it out from the centre of the cpu's ihs with a very small brush. And no need to apologise, your english is fine.![]()
Thanks again
I`m just confised because a couple of guys is saying that IC diamond will erase the write in the CPU and mine is still in warranty, should this be a problem?
From my experience, applying IC diamond for the first time won't erase the ihs marking but would darken the ihs. Applying it for the 3rd or 4th time will erase the marking but it reduces the temp by 1-2C compared to MX-4.
Stulid did a round up of thermal pastes here.

Another vouch for liquid ultra here. I'll never use anything else. Stains? Good polish will get it off, probably take a while but worth a 10'c drop![]()
