Lapping a CPU?

Alright, so i got this Q6600 Intel. I think it kicks ass as it is, but was curious about trying to overclock it. Now the problem is that i know that once you overclock this processor, the heat skyrockets. I am already sitting at 50C under load. I have heard that if you lap your processor and heat sink that you will drop in temps. I have watched few videos on this and seen the results.

I am kind of worried about trying this, but want to give it a shot. My question is, do you guys lap your CPU and Heat Sink? If so, how hard was this? have you ever wrecked your CPU trying to lap it? I work in a shop and we lap bearings all the time so i am confident on lapping. Just worried about trying this with a processor lol.

Now if i do try to lap my CPU and Heat Sink i would overclock a bit to try it. I also want to try liquid cooling. Does lapping your CPU also help with liquid cooling? I am thinking it does, but unsure what the end result is. Is lapping a CPU with Liquid Cooling greater result then lapping with Heat Sink?

Would love your guys opinions :)

Lapping will help a bit but it is not worth it IMO. What cooler are you running now?

LOL cooler? lol. actually right now i am just running stock intel cpu heat sink. I got 120mmx2 and 40mmx2 fans on the case. This computer is my old one, so it's the one i want to try new things with (ie liquid cooling). I though about giving that corsair self contained one a try, but would also like to try going full out with liquid cooling (because my graphics card is hot too NVIDIA GeForce 8800GT).

Reason i want to try new things with this one is because i plan on building a new PC this fall/winter. I just want to make sure i get it right lol. More expensive parts going into the new one.

So lapping isn't worth it? i seen that it dropped 20 degree in the videos, isn't that a lot? What kind of cooler should i go with then?
 
^ no you wont get 20 degrees...I can tell you that right now.

I did it as a project, my temps went down 3-4 degrees (fahrenheit)

Worth it? Not really...

Was it a fun little progect to do, you betcha ;)
 
Stock heatsink? Not even worth the effort. Lapping really shows it's true effect when coupled with a good heatsink, preferably one that is nearly straight in both axes, although anymore most heatsinks & waterblocks are bowed in order to account for the typically convex nature of an intel IHS. Even then, taking off a decent amount of material as well as lapping to a flat and near mirror finish, the best i would expect to see is maybe 2-3C difference, and that's with a lapped waterblock/heatsink as well.

In short...i'd suggest grabbing a decent heatsink off of newegg or such, in the budget range xigmatek as a decent selection of heatsinks.

Did you lap both the processor and the heat sink? (BTW what kind of heat sink you have?)

Of coarse i wouldn't lap a stock heatsink. LOL im a noob not a retard. IF i did choose to lap my processor, it would be with an aftermarket heatsink. I was even concidering (what you were talking about) waterblock system. BUT if heatsink doesn't really do anything other than 2-3C difference, then whats the point right.

From what i have seen on youtube people lapping the same processor as myself (Intel Q6600), they show using RealTemp a difference in temps up to 20C. Now they are also overclocked to at least 3.4GHz (stock clocking is 2.4GHz). When you guys say you only gain 2-3C difference, how much overclocked is that? Is it comparable to what the guys on the video are doing? What i am saying is if you lap your processor and heatsink with stock clocking, ya of coarse your not going to get results. If you have your processor, from stock, overclocked a fair mount then lap your processor and heatsink, that is where you see the extreme differences. Is my theory true or am i totally wrong?
