HOW TO REMOVE i7 IHS

corross · 03-23-2009, 08:34 AM

Hi guys. Today, my 4th i7 920 arrived. So here’s the guide how to get the pants off this baby.

First this is what you need besides the CPU:

1.razorblades
2.adhesive tape
3.permanent marker
4.Lighter / gas soldering iron or anything like this
5.something to clean the HS after burning (acetone + hankies)

If you have everythig collected, the show can begin.

Step 1 – prepare 6 razorblades for use
-->use some of the tape to protect your fingers

-->mark one of the prepared blades with the waterproof pen as shown in the picture. The cutting depth is max. 4mm for the i7! If you cut deeper, you may damage some of the small ceramic caps.

Step 2 – Cutting
-->Take your marked razorblade and cut from the corners to the middle (each side two cuts from the right corner to the middle, then from the left corner to the middle = 8 cuts around the CPU)

-->now cut the rest like this (each side one cut = 4 cuts, all in all 12 cuts)

Step 3 – get ready to burn
-->We’ll make a little fire under the IHS, but nobody wants to roast the PCB. So do the following:

-->the melting pot (if you heat up the IHS, the solder melts and gravity will do the rest)

Step 4 – Melting the solder
I’ve done this with a simple gas lighter. Sometimes you need to shake a little bit as you can see in the video.
Videos say more than thousand pictures:

After this, clean the Heatspreader using acetone

So heres the result, tested & works:

This is a photo of another i7, wich is currently running in my rig:

Carefully remove the tin with your razorblade.
Have fun with your naked i7 !

How the story continues: The custom-waterblock.

Copper 40x15x1000 vs. HS

What was your i7 Batch?

The copper met a milling machine, result: 29x38x12 + two holes

threaded (G1/4 inch thread)

I think you can imagine the leftover.
Performance:
- The water runs directly across the core now. CPUTemps are max. 30°C @ 4GHz full load, wich allows a nice 24/7 OC @ 4,4GHz; 1,39VCore (selected CPU, limited by the max. stable BCLK of my DFI LP UT mobo with HT&TurboMode on)

Regards from Germany,
Frank

30°C under full load with water? and that's with HT on? That's insane

Thats XS

I'll post some screenys of the rig when ready. Next stop: testing 8SSDs@Areca 1261ML on it.

Clearly not for the faint of heart!!.

Conquistador SW · 03-23-2009, 09:10 AM

Really nice

. How did you manage to seal the waterblock watertight to the core?

ghost_recon88 · 03-23-2009, 09:13 AM

What are your idle temps? And that's with chilled water I'm assuming.

corross · 03-23-2009, 09:22 AM

I soldered the IHS onto my waterblock. After this glued it on the CPU (two-component epoxy resin)

Yep, I'm using a "chiller". It cools the water down to 20°C. Idle Temp is 21°C.

Conquistador SW · 03-23-2009, 09:34 AM

Ok, thanks. I like how on the top of this forum there is a big warning not to pop the IHS and what do I see some threads lower……

Let's see some more pics of the whole set-up.

Yes, this is a great sample of craftsmenship. Looks like boble used a wrecking bar...

No problem, but I have to complete the rig first, like I mentioned before. The SSDs are on the way. Moreover, I'm building water blocks for the DFI, because the Mosfets get quite hot.

Made me lol too

HOW TO REMOVE i7 IHS

Damn, direct-die watercooling. You have balls lol!

The core aint that fragile that people tend to believe. I even lapped the core of my C2D E6600, and not a little either.

Bobsama · 03-23-2009, 12:54 PM

Wow--did you happen to have pre-removal tests for comparison? Because 30C... that's SWEET!!!

corross · 03-23-2009, 02:59 PM

Before this mod, the CPU temp was around 45°C with the chiller @ 20°C. So it dropped 15°C.

HuffPCair · 03-23-2009, 03:03 PM

FINALLLY i have been wanting to see someone do this with an i7.
Awesome job!!!!

Fafeifa · 03-23-2009, 03:06 PM

I'm going to try this over the weekend

QuadDamage · 03-23-2009, 03:30 PM

That's awesome dude. Popping a soldered IHS is quite a feat in itself but that direct-die water cooling is even better. Can't wait to see them pics of the whole setup!

Awesome.

loc.o · 03-23-2009, 03:36 PM

Very nice

Mescalamba · 03-23-2009, 07:12 PM

Thats not eXtreme.. thats totaly insane.

And that video .. wouldnt like to see what could happen if flame met CPU directly.. btw. how can CPU survive that much heat? (Yes I know, since it was soldered, it must been done with some heat too..).

Im tempted to try it too.. but its kinda expensive fun.

liftedcj7on44s · 03-23-2009, 08:20 PM

you have to remember intel puts these chips in an oven to start with. Cant remember the temp but its pretty hot. In that vid right as the IHS popped off it looked like the CPU exploded!
Awesome work. Might have to give this a shot. got any hi res shots of the Die BTW?
