Lapped core 2 duo IHS pics

Wouldn't removing the IHS significantly improve your thermal conductivity possibilities? Has it been done with good results? Or is it just too risky...

What was the difference between lapping and IHS removal?

Not much, Maybe 2 - 4 C under load. But I could also lower my Vcore one notch at my max oc and it became orthos stable at 3,6 Ghz with air.

Before I couldnt get stable in orthos at 3.6 even with water.

Yes, especialy with the E21XX series since they use tim between the sillicon and IHS on those. Not solder like the more expensive C2d.


It Is risky. I wouldnt do it on a more expensive cpu. You dont gain that much.

I have a e8400 now and Im not even going to lap this one because I wanna keep my warranty a couple of months more.. Never know what could happen with with the new 45:s. The sure have an issue with the temp sensors on these.

I lapped a 1.4Ghz P4 a few days ago... lol. 2ºC idle temp drop!

That was the crappyiest lap ever, it took about 2 mins.

Am I supposed to lap my IHS? As you can see, the gap between both core temps are a lil high.

So whats the best finish for me using AS5?

A friend sends me a Q6600 with IHS off:

For fun on my watercooled rig, with a 1.60v Vcore, 8x450:
idle: 30°
full: 46°
Water: 27°
Ambiant temp': 25°
gains are here

So you saying if i lapped my IHS even though it is flat i checked it .... i would get 4-5C more off of load temps and maybe 2-5C on idle?

My load temps under folding = 63-65C max on core 0 and the rest are 60-56-58 MAX

Wow, Thats Nice!

If your IHS is perfectly flat you wont gain anything lapping it. I havent seen a single flat original IHS.

It can be hard to se if there are "unflatless". You can be surprprised how unflat the IHS:s are when you start lapping them.

my e8600 had no contact in the middle.
so I lapped it.

its a void of warranty and it lowers temps somewhat.
gains can be good depending on cooling system.
