Well my new TR Ultra Ex arrived the other day and as with all of them is wasn't flat 
. So i decided to lap it and post my finding on here with some pics of how i got on.
The cooler that i had before was an coolermaster geminII with 2 coolermaster fans attached to the top of it. The thing was massive, didn't allow me easy access to the ram and was bs at cooling (hence the upgrade).
Now when i say the new heat sink was convex i mean convex....
To get this cooler flat i went to my fathers workshop to see what i could do armed with a metal file and some wet and dry.
First of i colored in the bottom of the heat sink with a pen
and went at it with the file for about 30 secs. Here is the end result.
as you can clearly see the top of the convex mound has been taken off and showing the extent of the curvature. It was then time to get on with the wet and dry, and to do this i re-colored in the bottom of the heat sink and set to work on some 600 grit. After about an hour i had this. As you can see there is still some of the ink left on as were not finished yet
15 mins later...
and finally
I had used the 600 grit so much that at this point it was finer than the 1200 grit that i had to hand so i didn't bother using it
All the while i was doing the wet and dry i was checking my progress with a metal ruler in the following places (Please excuse the bad effort in paint)
This is important as it will show up if you are sanding it down unevenly
Here is a pic of the end result
Now the important bit, how are my temps?
Well, with the coolermaster geminII @ stock i was getting 39,38,38,37 idle and 60,59,59,58 load. Not to good as you might agree. Now with the TR coupled with a Yate Loon D12SH-12 and a D12SH-12 swapped with the standard Lian Li exhaust fan i am now getting 38,36,34,37 idle and 52,48,49,52 load which is much better. I am a little worried about the 4*C differance and this may be solved by resetting the heat sink and/or when the the thermal past that settled in.
When i get some time i will overclock and see how much further i can get the chip and post up here. I could only get it to 3Ghz at 70*C load with the coolermaster and i am hoping the significantly improve that.
cheers

. I'll try some overclocks tonight when i get in from work and post up my results.
, anyway it was rubbish at overclocking. I have a Gigabyte GA-X38-DQ6 in the post atm so i will try some overclocking with that and see what i can get, hopfully arround 3.3 Ghz and above is my target
