Lapping the Dark Knight

post #1 of 18
Thread Starter 
I've heard there are issues with lapping this because the pipes are hollow but let's face it, I'm not taking off half an inch. Has anyone successfully lapped their Dark Knight?

Other than breaking through the pipes, anything else I should be aware of? I've read Tech Boy's (hope I got the name right) guide to lapping and I understand the process pretty well.

Also, if I lap the Dark Knight, do I need to lap my CPU? That, I don't feel comfortable with. I'm guessing the CPU tolerances are much tighter than that of the pipes and fins assembly of the BK.

Why wouldn't you be comfortable with lapping your CPU? (Especially since it doesn't have pins)

The IHS is actually quite thick and near impossible to sand all the way through with hand lapping. (Unless you're like the uber-determined guy who lapped his Q6600's to the die)

I meant my new q9550 that's coming, not the e5200. The e5200 is actually destined for a machine my brother might be building. It's a 250 dollar cpu. Voiding that warranty would break my heart. Voiding a $50 HSF, not so much.

I lapped a Vendetta 2 (similar cooler with HDT). If you're going to do it, start with a high grit.

Lapping barely did anything with my cooler, so I recommend against it. I used 1500 then 2000 and by the time I was done, the copper was soo soft you could leave a fingernail imprint in it without even trying.

I lapped my DK without any issues with the heat pipes. It looks great with those 3 shiny copper heat pipes but you only get to see it for a little bit! LOL

Did you see any difference in cooling?

It was new when I lapped it. I was not happy with how rough the stock finish was so I lapped it right off the bat! I have lapped other HSF's in the passed and I noticed a 2-3c difference on average. It's not a big difference/deal but hey I had the thing in my hands for a hour or so for some piece of mind.

In my opinion don't lap your heatsink, I don't see much performance coming from it.

If you choose to lap your heatsink it's best to lap the heatsink and cpu both at the same time that will yield the highest amount of performance.
