Was thinking about yesterday when re-doing the paste on my Corsair H50. On removing after putting AS5 fine it seemed only have the surface was covered. I changed brackets in order to clamp down more which should force the heat spreader a little flatter. Still thinking I'm going to lap the H50 copper plate sometime this week. Not too keen on doing the cpu top.

I doubt the H50 plate is the problem..

Wow, all that money and the base plate is clearly rough, uneven and difficult to install?
Dayum..
Lap your cpu as well, shocking to see how uneven the surface is.
And all that money on a CPU and it's built so it can't be cooled? Dayum...
Actually, why do people lap heatsinks, even the expensive ones? They're not even either, so to those you can apply the "all that money" statement as well.

Umm, ok.. That's not a point I was trying to make. You seem to have somewhat taken offense. All i was saying was I was under the impression that the H50 was THE one to have at the moment and after reading reviews and user reviews you seem to have come to a different conclusion.
No offense taken. 
Just taking a dig.
I had the same impression and alot of places indicated a nice shiny finish, yet in reality it isn't that perfect at all. It still works like a dream though, knocking 5C or more of the stock temp under idle alone.
Thing is, I think it can do better, so want to lap the thing, but do not want to lap the CPU. I think at R700 or so I'd rather mess up a H50 than blowing the warranty to hell on the R2.5K CPU.

There are a few things you need to realize:
*Zalman make **** products. There is the main reason your temps didnt get any better.
*The best thermal paste you can get in this country is OCZ Freeze. Try that rather. take 2 sells it.
*You may have applied it incorrectly. The best method, backed up by overclocking professionals is always to put a small blob in the center of the cpu, about the size of an uncooked grain of rice, and then put the heatsink on. The cpu cooler base will spread out the thermal paste evenly, and avoid air bubbles.

Yes, but that depends on the viscosity of the paste. Rather thick pastes don't fair so well with that method. AS5 warmed up a little, however, is excellent in that scenario. Thicker clay-like pastes will barely spread.

That was not from anything i read, i mentioned it because i actually bought and used the stuff and it was horrible.
In my opinion thin does mean bad because you have to struggle to get any out the bottle, the coverage is really thin. The layer is very thin and in my experience it was the worst thermal paste i have ever bought in my life. My temps actually went up from the old cheap white thick paste i used.
Would that title not go to the Coollaboratory's LiquidMetalPro (Galinstan liquid)?
How easy is this stuff to apply in comparison to AS5? AS5 is very slippery once I heated it up. I don't want to go waste more money on something that's a bitch to apply.

There's your answer. The pads are apparently very good as well without the issues with aluminum
Found no fan speed control in the Bios. I noticed a few scratches on the heatsink when I took off the old paste. I think I'm just going to take off all the paste again and leave a small amount on the heatsink and see what happens
I've applied a small amount of paste to the heastsink and the temps have gone up. They're now up in the low 50s 
. Less paste has resulted in more heat.
IIRC my 965P S3 motherboard is compatible with the E7500. Perhaps even a quad core if I end up upgrading

Tbh that looks like a bit too little.
