Can I Remove My i7 860 IHS Like the 3770k Ivy Bridge - Page 2

post #11 of 17
oh yeah...heh, you can remove any IHS. I've actually been doing it on a lot of older LGA 775 CPUs recently since I am considering getting a 3770K and there seems to be at least some truth to this IHS scandal that Intel has going on. So I thought I would practice a bit on CPUs that have IHS's that are actually hard to remove.

when it's warm outside, my max temps on my i7 2700k is 60c after 12 hour of prime95.

Materials you need:

Some very thin blades (as shown in the pictures), a torch/lighter, cardboard.

1. use blades to cut into the rubber seal between the IHS and PCB, starts from corners and slowly work around the chip until everywhere is cut through. Be careful don't force it as there are surface-mount component on the PCB under IHS.

2. Insert four blades into the four sides between IHS and PCB, they will exert force to crack open the IHS in the 4th step.

3. Use a thick plastic/card board and cut open an area about the same size of the CPU and place the CPU at the opening, IHS facing down. Use tape to secure the CPU on the card board. If possible, place something (as heatsink) on the pin side of CPU to help dissipate extra heat. That help to prevent melting the solder on the pin side. Don't light up the cardboard.

4. Use a torch/light to heat the IHS from bottom. For about 45-60 seconds the solder melts and the blades will pop the IHS off.

5. Use blade carefully scratch off the soft solder on the die and clean the PCB. Don't polish die with sand paper (although I did).

Now you have a naked die for some fun. Core temp should be lowered by 5-10C. Be sure to test the temp before removing IHS for comparison. For the IHS you can drill a hole and make it a nice geek key chain gadget.










wooow!! veery nice!!

I'll do that with my 3970x, I think I'll use a lighter.
But a question even if the IHS is soldered do you still have a temp gain of 5-10 degree using liquid metal paste?

Be sure to use a good lighter. Quicker you can remove the IHS, less risk to damage the chip.
In my case core temp did drop noticeably on i7-960. I was using MX-4 or Gelid Extreme I cannot remember. I think you will need to try and find out. smile.gif Liquid metal is proven to be the best TIM on bare die.

Well I did it with a small candle it worked perfectly and beautifully. But now... I need a spacer because without ihs the waterblock doesn't reach the cpu!!!!
I didn't thought of this, and also without the metal that made contact between ihs and cpu there is no contact unless I put alot of liquid metal thermal paste!!

What to do?

By the way a few pics








And by the last one I'm lost rhe waterblock doesn't touch the cpu

Well I took off this



And now the motherboard (asrock x79 champion) looks like this:


By the way the cpu is a 3970x. Hoping it survived smile.gif

Logically, the next step is to solder the CPU to the heatsink.

Makes you think.
