THat's news to me. No where in any literature or white papers I have read does it say anything about warranty hinging on cooling used. Link/proof please.

I did make some interesting discoveries. Though some where obvious... For one, the HK 3.0 bow is caused by the top piece of the block, not the plate itself and therefore it can be lapped. I lapped mine to a perfectly flat shine, according to a few new razors, and then re-assembled. The HK 3.0 bottom plate retained it's bow when assembled.

Another thing I discovered was they are actually rather thick. I was able to lap this the first time and then go over it again with some 800, taking off a few more layers and then polish it with a 2500 grit and I don't appear to have compromised the integrity of the contact plate. I had heard of people lapping too much off and actually puncturing through the channels.

There is also only one, out of a possible 2, correct way to mount the contact plate for the HK 3.0. If you will look closely you can see the contact plate has slight angles at the end of each of the channels. These angles need to be pointed towards the outlet for the block.

I re-mounted the HK 3.0 5 times just to make sure that it wasn't a mounting issue. The temp rise was still there.

Today I removed the block from my loop and dis-assembled it. Both o-rings were in place but as I removed the block I could hear the small silver plate on the inside rattling. As I removed the contact plate the silver "pressure" plate came with it so I guess I will never know if that was the problem, other than that the block looked great. It had a bit of tarnish on it so I removed it with a quick surface lap, re-assembled the block, taking great care to make sure the silver plate was in place. I then re-applied TIM and re-mounted the block.

Not only did the 6C jump disappear, I was able to dial in the mounting pressure and get a 1C drop in load temps.



I wish I had recorded the original temps of my block before the original lap. It was a very, very slight lap to an area about as large as a dime in the center of the block (it was dis-assembled). I think I say around a 3-4C drop in temps if I remember.

Wait shrimpykins...so are you saying that lapping the HK 3.0 got you a 1C drop in temps?

The second lapping which was a lap of the entire bottom side of the contact plate gained me an extra 1C. This is due to the bow that is designed into the HK 3.0.
