e21XX IHS Removal

Am pretty certain you can remove... just if it would work is another matter :)

You can sand them down "lap" them in order to make the IHS flatter and therefore improve you temperatures

Didnt think you could remove it? Only sand it back so its nice and shiny/flat.

Thats called lapping. This thread is about IHS removal. These e21XX series CPUs are different to the majority of core2duo CPUs, in that the e21XX series, mostly do not seem to have the cores soldered to the underside of the IHS. They are as easy to remove as the Ahtlon 64s were. Same principle. Just razor blade around the edges carefully. This is why these cpus run high temps under load when clocked high as the internal interface between Cores and IHS is poor. Hence lapping does nothing for these.

Was wondering what results people have had. A guy off of XS got his load temps down 10-15c after he did his.
 
It appears it can be done on the L2/M0 E2xxx's and E4xxx's. The main issue is that your Core will sit below the LGA775 retention bracket meaning no cooler would actually make contact with the CPU. You might drop the temperatures a little bit by removing and then properly remounting the IHS but that only really applies to a cpu which had a poorly mounted IHS to start off with.

If it were me I'd just lap it.
 
Lapping my 2140 knocked 8*c off the load temps at 3Ghz + Equalised the two core temps.

I've been toying with the idea of removing the IHS... Yet us know how you go on mate :)

No probs mate will do. I ordered a Thermal Right Ultra Extreme today and a couple of fans and some AS5. I had some AS5 I bought years ago. A tube has lasted me like 4 years! Does it have a shelf life on thermal materials? ;)

@ MUL: Yeah the retention bracket needs to be removed so the CPU sits not very securely in the socket unfortunately (plus a mock up shim is usually recommended) ...hence you really need to use secure heatsink mounting system with screws/threads rather than swing arm like the AF pro. Unfortunately straight after I bought the Thermal Right Ultra Extreme (TRUE) I read of some people not liking the way it mounts. So not sure how i will get on with that. Some people made some mods to the mounting system allowing the threads to go further through to the underside of the mobo. I will see what happens when I get all the stuff together. Only other thing that concerns me is this whole contraversy over whether to lap the TRUE or not. I think I might. We'll see.

Thats some good results with lapping I must say. I'm just not sure if I can be bothered with lapping when I bet I'll still want to go naked afterwards anyway! ;)
Nice to hear though thanks. I will try to provide some pics and what not for you guys on here. What did you get up to with your clock? I got an e2140 M0 stepping and I hit a FSB wall at 400. I can occasionally post at 410/415 but 400 is rock solid at 3.2ghz ram 1:1, but load temps are higher than I would like. Load temps are under 60 if I have the freezer pro fan at 85% plus, but that is too noisy for me personally. When at 60% and I can barely hear the fan, load temps can climb to high 60s.

Thing is, it idles very low regardless of clock.

I also have speedstep EIST thingy turned ON with no effect on stability. Nice to save on power/heat.
 
The 8*c odd i lost from the e2140 was mainly due to it having a bulge in the middle of the IHS... this was an extreme case and not all cpus will loose this much (sometimes nothing at all, but equalising the core temps).

Quick shot of the [email protected] in my water setup. Not sure if it's gonna be prime stable for 12hrs, this was just for an overclocking compitition over on another forum :-

Nice. I know there is a trend developing towards prime-stable fascism, but I like to see everything possible - even if this was just a suicide shot it would still be highly impressive.

What kind of RAM is that?

[Edit]Oh - and good luck Pendulum666 - I can't see it working personally, but kudos to you for the effort.[/Edit]
 
Well guys still waiting on my delivery but I will take the CPU out soon and get to work when I get a chance today. I have done mods on expensive hardware before with chances of killing it and all fine. Atleast this CPU was only £42! ;)
