CPU Lapping

[xserd]

Quick question guys, does CPU lapping really improve temps? anyone still do this?

[Reslivo]

As far as I'm aware, people still lap Sandy Bridge processors to improve temps, if it's necessary.

With Ivy Bridge, delidding is apparently the way to go.

[Umeshwarnath]

please don't try anything of that sort....it is very risky business and the returns are not worth it!!

Delidding does improve temps quite well on Ivy Bridge CPU, but take note that you will lose your warranty. If you delid and the CPU breaks, you've pretty much had it unless you want to buy a new CPU.

Yes it will help

No it is not worth it unless you do it just for fun. its quite risky and your warrant voids (doh)

I did it with my i7 920, it does improve your temps but the time it takes makes it not whorty.

Sandy bridge chips were soldered to the IHS, so lapping the IHS would improve cooling performance.

Ivy bridge had TIM between the chip and the die, so delidding it would be a lot more beneficial than lapping. Also, running it without a lid altogether would be best; it'd be risky, but would have the best temperatures.

When you have to delid the IHS from an Ivy CPU you need a VERY sharp and thin razor. and I still don't find using it without an IHS safe, since there's a slight chance that you might damage the die, which is very easy to do.

[Fordox]

the die isn't the problem. it is the razorblade thing.

you cant put your razorblade more than 2mm under the IHS, because you will cut in some small capacitors under the IHS.

Running it without IHS isn't a problem, a lot of chips had, and still do have no IHS (for example amd graphicscards and various chipsets).
