Default Lapped my i7

Well i finally got around to lapping my i7.
Temps are about 2-3C better on load but i mounted the block in a hurry and will do it properly once i move to my TJ07 build.

Here are the pics of the process.

Wow the i7 is very unflat as you can see, the middle and corners really needed to be sanded town quite a bit.

Nice!

I've been thinking about doing the same thing as mine definitely looks uneven.

The chip I've got does 4GHz at 1.35 but runs a lot hotter than the other two that did lower speeds at the same volts.

Interesting. That's actually fairly close to what my processor's IHS looked like, I think. I think I got a degree or two improvement, although I presently have temperature problems with my processor, so it's hard to say for sure.

Takes alot of balls, personally I'm not sure voiding the warranty is worth 1c or 2c better temps.

Looks great regardless!

No kidding. Definitely different than the horrible Q6600's. I guess that means (assuming this is the norm) that even stock, we can expect good centre-point contact between the IHS and heatsink, so minimal gains from lapping.

I hear that. My E5200 was so concave I went into lapping intending to get it as flat as possible no matter how long it took! But after I only had minor grooves in a razor test, I got so bored that I started checking every 50 laps or so and decided screw it, I'm not patient enough for this

you and me both i might try this if i buy an upgrade but for a 1 to 2 c drop is it really worth voiding (nice job by the way)

Looks good! I did the same with my old Q6600. I couldn't believe how much material came off before the processor was flat. Took me quite a while. I found that the mounting pressure of my TRUE was reduced due to my processor being a bit shorter. I still need to lap my TRUE as well, so I'm probably going to need to do the washer trick to increase the pressure by the time I'm done
