Lapping your cooler/CPU may or may not help your temps, depends on how much a mismatch the 2 surfaces have. You wont know until you try, sometimes it makes a big diff., it did on mine.

Note: Read my earlier post.

Correct. It's all about risk versus reward.

Removing your heat shield can pay enormous thermal dividends. But the risk of damaging your CPU is high. Lapping your sink and heat shield give a solid return on investment of time and effort with little risk IMHO. (Other than voiding your warranty, of course.)

I'll be lapping my Conroe & TT120 in a few days.

Are you saying I will see a drop in temps, consider that my idle temps are currently 25-28c with load 40-45c, which are pretty good temps anyway....

I'd love to drop the temps further but doubt that they could get much better

IMHO you would see a drop in temps (3-6C ....? - maybe). But why do it now? As you stated, your temps are great!

Yeah, they are great temps. But I want to hit 4.0ghz with this chip and right now its a no go because the temps won't allow it.

I recently had it a 4.0 ghz with 1.625v (a bit less after droop) but the load temps went to 62-65c.

If I could drop my load temps considerably then 4.0ghz at 1.625v would feel a lot better!

I'm sure you are aware of the impact your ambient temps have on air and you may very well get another 2 or 3 degrees drop under load. but that still wont give you what you want. Water perhaps?

lapping is not an exact science, insulglass posted another thread here about the need for good airflow over the heatsink to remove the heat from it. Your IHS and HS might not be perfectly flat and not performing as efficiently as possible but your airflow over the heatsink might be removing as much heat as it possible can, lapping your IHS and HS without improving your airflow might lead to no benefits at all, you might be able to get the heat into the HS faster through the IHS and HS contact but you won't be able to get that heat from the HS to air fast enough to make it worth while.

Still if your warrenty means nothing to you, it can't hurt. Although you might be one of those unlucky souls who actually has an already flat IHS and HS, although I highly doubt it.

After lapping don't lose heart if the temp drops aren't what you expected, you might just need to improve your case airflow or use a different method of applying your TIM.
