CPU Delidding

[MultiDJRoni]

Hey there

 

Digitec is currently offering a discount on the delidding tool from der8auer. But im wondering if i really need this expensive UHU High temperature silicone or if i can just fix it with a little bit of normal adhesive. (I know i coud just do it without the adhesive but i might want to sell the CPU in the future so i want to it)

If your referring to remounting the IHS a common product used is RTV gasket maker, you just need 4 small dabs in each corner to hold it in place.

I never even remount the IHS...

 

I just remove the torx screw from the bottom of the holddown, potition the IHS on the old glue outline, put the socket holddown back down (but of course it won't clamp anything with the bottom screw missing) and then I reinstall the bottom screw, using that as the clamping force on the holddown. Its a bit tricky, but if done right, you can use this method to clamp it down without the IHS moving.

 

I've seen others use dots of superglue on the corners. Its not too critical.

So the CPU Should not take damage if i just glue it down with normal adhesive? Because its a 7700K and i dont really want to destroy it

You should be fine. If you use liquid metal paste, be sure to insulate any pads or capacitors on the PCB

ok thank you for your answers. But which pads and capacitors do i have to insulate? I have never seen that in a tutorial

See those four gold dots to the left of the die? If you're using metal thermal paste, just be sure to cover them with something like nail polish. If you're using something non electrically conductive like MX-4, don't worry about it. The risk is that any stray CONDUCTIVE paste on those pads will destroy the CPU.

 

Some CPUs will also have a row of capacitors next to the die, such as the 4770k. Those capacitors also pose a risk when using metal paste, but thankfully the 7700k only has those four little dots to cover when using metal paste.

 

 

I delidded my 6700k and I could not be happier with the results. It made a massive impact on my temps.

Oh wow, thanks for the information. Thats something i wouldnt have done elseway. Tecnically i also just can tape them with electrical tape, because its thin enough to not interrupt the temps, right?

 

And yes, i will use metal paste

Hey i have delidded my intel core i7 4790k with a razorblade. It was not so difficult but it needs some time and concentration. I would use liquid metal this thermal compount is pretty good but you should isolate the liquid metal on the DIY for example use a sticky thermalcompunt non conductive and place it around the chip. After that do nothing more than clean/remove the HS from the last high temperature glue and just press it on the chip. If you does it correctly you feel the HS floating on the diy. At the end you intall the cpu in the mobo and your cooler has got a lot of pressure so there is nothing movin. By the way if you remove the cpu your non conductive thermalcompound for isulation sticks the hs and DIY together.

I used a 9.99 delid tool on eBay...... worked on 7700k and used liquid metal and some cheap black silicone to stick it back together, that was like 2 months ago and had no issues, temps dropped by 19c overall for me, after I put the metal on I then applied the silicone in a thin layer round the outside of the his and placed it back in the motherboard and used the socket to hold it while the silicone dried, worked like a charm just remember the his will move a little when clamping it down, good luck

Well i have watched now every delid video on youtube (at least it felt like it) and not a single one said that you have to cover those gold dots. I also rode that electric tape will melt because of the high temps. So im not shure what i have to do when delidding and what i souldnt

Nail polish will work on the dots, but I just used electrical tape on mine lol

 

Really you just want to prevent the metal from getting on them during reassembly, and as long as nothing moves, it should be fine. I used electrical tape on a GTX 1080 and it didn't seem to have thermal issues.

Ok so i was in a DIY Store today and i bought this glue here (They didnt have silicone that was temarature resistant. Yep, swiss DIY Stores suck) http://www.uhu-profi.de/produkte/montage-konstruktionsklebestoffe/detail/uhu-kleben-montieren-dichtenglasklar.html?no_cache=1&step=332.5

 

I think it should work since it is temparature resistent up to 100 Degrees Celsius and is permanently flexible, just like silicone. At least i hope so. Do you have any experience with it or is UHU not a thing in america?

That stuff should work fine. Just let it fully cure before using the CPU

Ok, and would you recomment just putting it in every corner of the CPU or go fully around it like you would with the normal silicone? (Ecept with that little gap)

I used superglue today, I just did it in the four corners, using the old glue's outline to line up the IHS, and then I put it in a clamp until the glue cured.

Ok, thak you. You helped me so much I will keep you updated with the results

 

[MultiDJRoni]

Aaaand one last question. Can i use Arctic Silvers ArctiClean to clean the thermal paste inside the CPU? After i delidded it?

I can't wait to see how it turned out! I've gotten addicted to delidding CPUs, I'm delidding pentiums now

I've never used it, I just use rubbing alcohol, but I'd imagine it would be fine. The metal thermal paste needs a very clean surface, and at least for coolabratory liquid ultra, you'll need to use the included pad to actually roughen up the underside of the IHS for the metal paste to "wet" it

 

Instead of applying it with the brushes, I found it easier to just use the tip of the syringe to apply it. I've had the best results applying it to both the IHS and the die.

Ok so i hope i didnt fuck up too hard. I removed the heatspreader, replaced the compound with the liquid metal one but when i clued it back together i noticed the heatspreader is upside down (see pictures). I dont think it should make any difference, or does it?

It might sit a little uneven due to the old glue, but it really shouldn't be much of an issue.

Phu. Ok, so in about an hour i will build it in to my PC and hope for the best

Haha, i hope i dont have to

 

But there is another question in my head. I have my Motherboard mounted vertically in my case, and since it is LIQUID metall, can it drop out of the CPU, or is it "non-liquid" enough that it souldnt move inside the CPU? I know it sound dumb
