My 4770k never gets pass 4.3ghz. Even with water cooling, it hits the thermal throttling temp everytime I play games or use Prime 95. so I followed the tutorial online and bought all the parts I need to removal the IHS.

Pretty damn easy if you have the proper tools, I spent about $25 for all the tools I need. Took me 3 minutes to set it up and removed the IHS.

The CPU is very light without the IHS, need to be very careful not to scratch the core.

Need to remove the glue surrounding it, a credit card will do the job cleaning it up.

liquid metal, whatever people call it. It is conductive so have to be very careful.

It comes with the new copper IHS, it claims to have better performance than the stock IHS. Many buyers disagreed but I still use it anyway.

I have been using high-end thermal paste since Pentium 3, now people use these thin metal sheet as they claim that transfers heat much better, oh well, let's give it a try.

I will do a lot of stress testing tonight, idle temp seems fine except Core#0 is bit higher than others, might re-do the IHS again. Hopefully, no more throttling.

Idle before

Idle after

4.2ghz (68C to 80C), before it hits 90C easily

4.4ghz - first time hitting 4.4 stable, but temp is crazy high, will reopen the IHS

Material Thermal conductivity [W·m−1·K−1] Notes
Diamond 1,000[4]
Copper, pure 401[4][7][8] For main article, see: Copper in heat exchangers.
Aluminium 237[6]

Thinner the better. If you had a slab of diamond, it's 5 times better heat transfer than aluminium. :lol

I remember the days of lapping a heatsink to get better heat transfers. Those days were fun.

You could also try polishing both sides of your IHS.

The 4770K had such shit paste that Intel actually did something about it :lol

A minus of 10C is pretty good with a simple DIY.

Maybe I'll try this on my 6950X when I feel gutsy enough...
Overclocked to 4.0Ghz. On water cooling, it's running at 28C idle and 45C on load. I was blown away...
I guess I could push the clock speed up some more as I have so much temperature headroom.

[smoothie.]

what sort of performance gain are you looking to get from this?

I used to OC my 2700k for fun, but random instability like bsod once a year turned me off from running close to max 4.8, and now im down to about 4.4.

For some reason I never thought about that piece as being removable. Do people make heatsinks that mount directly to the chip so you can remove this piece in between?

[DragonChi]

It's also known as a heat spreader on top of the chip to cool it more evenly and effectively.

i'm getting too old to bother tweaking for more serious overclocking

also, slightly different pressure delidding and your chip is done...and you can't replace it because it's EoL meaning your mobo is useless unless you buy the same chip used.

Same, I used to love overclocking a few years back. Overclocking the G3258 was mighty fun and I eventually had it at 4.5GHz at 1.25v.

But I have a 6700K now undervolted at 4.2GHz. I prefer silence over all else. I can't hear any of my fans even at load.

Found this today, looks alot easier to use, and I'm sure it could easily be resold after

[asian_XL]

it seems like the stock IHS is much more efficient than copper one I bought.
re-do the whole thing, now it is 80C max
