Well those temps are already great out of the box. I hit 92c with my 7700k at 5ghz with 1.31v. Delidded and temps dropped to low 70s. Reduced the voltage. Stable at 1.285v and now I get 65c. This was with Asus Real Bench. What is your cooling? I am on a full 720mm custom loop. I also used the glue method.

Temps shoots shoot up exponentially though so going to 1.3V definitely pushes me into the 90s. I'm using a Noctua D14 and the previous temps were with MX-4. So really it comes down to the chip.

I am a bit worried though because in my re-de-lid I added a bit more CLU but in re-examination my photo seems to have enough, and seeing actually some of it leaked off the die (perhaps it was during the relidding process).

You should use a thin layer of thermal paste on the die, no paste under the HIS, and no glue at all. That's what I'll do when I receive my Rockit Cool 88 and Thermal Grizzly Conductonaut.

I used a thin layer initially, and in my disappointment over the small delta I added a little more. It's not like mountains full, but I put down like half a grain of rice. I'm just worried now it may leak onto those bridges. I'd be less concerned if I had put something like clear nail polish.

My CPU Is sitting in the Rockit spider relidding tool right now, but now I'm itching to take it apart yet again. I'm also used less RTV this time but may consider doing just the 4 corners.

1st RTV:


2nd RTV:


Another data point is that at 1.34V for 4.9 ghz now I'm getting 82C max (before it would soar past 90s). My chip is definitely not the best and I don't see hitting 5ghz for 24/7 use with those voltages, so I may just settle with 4.9. I just want to get cooling improved a bit. I think lower-mid 70s would be nice.

Edit: Gaming in BF4 never surpassed 69, so it may be good enough for me as we all know Prime 95 isn't accurate.

Yea gaming for me I stay in the mid 50's. The Real Bench puts me into mid 60s. I really go off gaming temps cause that is all I do, but for benching purposes I use the software stuff.

Cooling hardware? Prime95 is not often used to test stability because burns the cpu to temps it will never reach in normal use. I try other test programs like realbench (bench and stress), intel xtu (bench and stress) and real life apps like bf1...

By using glue you recreate a gap between the IHS and die, which affects temperatures. It isn't a problem at all to not glue everything back on, when it's locked on the mobo socket it won’t move a bit. The only reason why you would want to relid is before RMAing it to Intel wink.gif
You will have to redo the liquid metal pasting if you remove the CPU from the socket though.
At least it's safer IMO.
I wouldn't be comfortable putting back on the CPU cooler on the IHS without cleaning everything up and repaste, so the liquid metal on the die should be no different.

Prime95 uses AVX2 instructions, which is why it runs so hot. It hits the silicon harder than anything else. The load that is put on the CPU is nowhere near what a game would, plus a little more voltage is needed as well.
That's why they made an AVX offset option in the BIOS (at least on Asus motherboards, I don't know about the others). If you pass stability at 5.0 GHz on games and Aida64 for example, but not AVX2 enabled applications like Prime95 or Intel Burn Test, you can set the AVX offset option to let's say 4.8 GHz, and no more BSODs. Sadly you can't set a custom voltage with the AVX offset, that would have been great.

I agree with you there Prime 95 isn't accurate for real world testing but at the same time I want my system to be rock solid stable. The thing about builds is once I finish I don't ever want to look back at it, so I'd rather be safe than sorry. I don't want 2 years later to figure out why my system keeps crashing or if I need to raise vcore at some later date what I should raise it to. I also know that Prime 95 runs very hot, but I've also seen people obtain lower temps on Prime 95 or other AVX benches too.

That's why I'm shooting for lower temps still. I'll give my CPU a whirl tonight and if the temps are better with the job redone I'll be happy. If not, oh well. I can live with a mediocre chip I suppose. I have yet to become lucky with the silicon lottery.

It's a heatsink, I think?

- Red Silicone RTV for re-sealing

Images below. A few things I did learn though as well as a few thoughts:

- Probably used too much RTV to reseal it back. I would use less in the future. I used a syringe and needle for the thin application.

- Rockit Cool tells you to use your fingers to rub the silicone off the CPU. I tried that but it was slow even with nails. Credit card worked beautifully. Be gentle though because if your card isn't all worn out it may have relatively sharp edges that can remove the silicone fast. I wouldn't recommend using metal credit cards (ahem Chase Sapphire owners). As a tribute to United (RIP), I decided to pull out my old MileagePlus Explorer card.

- Kryonaut was applied horribly as you can see, but I suppose it should still work out in the end once you smash it down and let it spread naturally.

- Not sure if I put enough CLU. I put very little on and was able to spread it and saw little bumps suggesting there's still too much so I tried to get it down to a film. But every video I watched seemed to put way too much and some applied to the IHS too.

As for temperatures? I ran the exact same settings at 4.7 GHz, 1.25V, and while previously I got a max of 84C, my max temp is now down to 71C in Prime 95. A 13C drop in temperature. I'll take it.



















Oooooooh, I need the info to add you to the list but love the photos! thumb.gif

Some pics of it











Temps went down at least 15c, since (without changing voltages as there were without delid, temps where reaching 72 and 74c.
Now after some quick stress tests, there are around 55c at 5000 1.175mv set on bios with llc6:







Happy with the temp gain!!!
EDIT: Used the rockitcool tool with the relid tool, with coollab ultra...
The tool is excellent and really easy to use. I recommend it.

Give Vagur the required info and I'll add you to the list! Awesome pictures though!

I couldn't agree more.
