Are you guys kidding here? I find it really hard to believe lapping will drop temps 10 C!!
 
Never mind the destroying the warranty for the cpu/cooler. Can somebody show me of a review site showing a benefit of lapping? I haven't seen one website review showing a clear benefit esp. given the risks....
 
Show me something from Toms/Anandtech or other reputable site where I can trust the data to be reliable and you'll have me convinced... :) I would think Thermalright created this cooler convex for a reason, to maximize cooling, their engineers would know all about these issues!  
 
But hey, if there is some objective evidence, I got some work to do! My rig comes in on Friday and I'll have some work to do. :)


What you have to consider is that even though people at Thermalright would have known about it they would have to find a acceptable "range" to design the HSF around since each CPU is unique. The lapping benefits will differ depending on each CPU. I have personally seen some of these 10C or so temp drops after lapping (esp. on old Prescott CPUs), while other times it is about 2-3C. It all depends on if you want to risk the warranty and get cooler or vice versa. Another factor is the quality of workmanship and the concave/convexness of the CPU.

Shadow: Thanks for not flaming me, I had a feeling some people might get a bit upset about my remark.
 
However, I'm talking bout a modern pc, the q6600. There was one review site that showed no diff (forget which one, can google for it) and that makes sense for me. I agree the TRUE may not be 100% optimized for older chips in terms of modern chips, it should be for newer chips. Again for 2-3 C, it's not worth me spending 3+ hrs for very little gain and losing my warranty....

Even on the newer CPUs you can still expect about 7-10C drop. Seen this with a E6600. Again it depends on each CPU.

Hmm.... well let me OC my cpu to 3.6 and see how hot it gets this weekend. I'll think about the lapping issue after that. Some before/after screen's would be helpful! :)

^ Agreed, unfortunately I usually lap CPU/Heatsink any way even before OCing so I don't have any sceenshots. Make note that those 10C drops were due to lapping BOTH CPU AND Heatsink

 

Here is a pic of one of my lappped CPU:

Had anybody consider that temp. decrese is due to less space between heat source and spreader and so it could be important to lap as deep as possible and not only to match two surfices???

be difficult as gpu is not mounted in a socket so how could you take it out and do what is described.

the concavity probably comes from how they are stamped out of the sheet.
 
does removing the protective layer cause corosion problems.
 
I used to alwayes hear about removing the IHS from back in the s939 days.
 
does anyone still do this?

This thread inspired me to do the same with my E8400:
 
Started with 400 finished with 1000.

Temps are about the same... But it's way hotter today compared to when I did the pre temps. Also I am hoping once the thermalgrease is broken in it will be a bit lower. 36c before and 36c after.
