Default Delid Results - Core i7-7700k and H115i (over 20c drop)

BLUF: I would do it again in a heartbeat. Dramatically lower temps and a relatively easy process.

After installing a shiny new H115i on a shiny new Core i7-7700k, I was dismayed to see it hitting 80c under load and OCed to 4.9ghz. I decided to make the leap and delid, after seeing how straight forward it look thanks to Rockit88's tool. So I grabbed one, plus their relid kit, and Liquid Ultra off Amazon. Off to the races!

Before getting started - slightly nervous about the possiblity of wrecking a $330 chip...

The kit is well-made, and the multiple videos on their site and YouTube make it fairly idiot proof. It included a wooden pick/scraper that came in handy for getting the JB Weld type adhesive removed from the chip and spreader.

When they say there's an obvious "pop" as the adhesive releases, they aren't kidding. It was surprisingly easy.

Taping off the die:

Applying the Liquid Ultra:

This stuff really is interesting. It moves around like mercury, not so much like a liquid. It cleans up easily with rubbing alcohol in case you get it on the table. Or the floor. Or your chair. My young assistants helped make a bit of a mess.

Applying it to the heat spreader:

Time to relid:

The super glue I was using was the type with a brush - looking back, not the best choice. I'd use one with a precise applicator tip, as I had a tough time getting it just in the right spots. It also made removing it from the tool difficult after it had set - I ended up having to use some q-tips, Goof Off Super Glue Remover, and a knife to get it out. That was a bit sporting.

I used Arctic Silver Arctic Alumina as the interface between the heat spreader and the H115i. I used the method recommended by Arctic Silver, a 1mm wide line down the vertical center of the heatspreader.

Now the fun part. IT WORKED.

Results:
Before Delid at 4.9ghz:
  • Idle: 49c
  • Load: 80c
After Delid at 4.9ghz:
  • Idle: 27c
  • Load: 57c
After Delid at 5ghz:
  • Idle: 39c
  • Load: 68c

5ghz wasn't obtainable before the delid - was stuck at 4.9ghz no matter how how I pushed the voltage.

I'll probably drop it back down to 4.9ghz for long-term. Then again, I should see a few more degrees drop once the Alumina is set in. Screen captures of the results follow.

Great job PapaChop,

I have the same kit from Rockit 88 and an i7 7700k overclocked to 5.0 GHz at 1.44 v.

I will be doing the delid and relid later today. I want to get my Vcore down below 1.35 v with lower temp (been hitting 100 C with Prime 95 and 94 C with Realbench).

Thanks for sharing your experience and wish me luck!

You bet. I didn't want it running above 70c or so, and there's no way I was going to let the wife's i5-6600k outspeed my newer i7.

Proof again that Intel need to stop cheaping out on TIM and just use liquid metal TIM, It would only cost maybe a few cents/pennies on top of each CPU.

It's savings like these that allow Intel to charge such bargain basement prices for their cpu's. NOT.
