Does delidding give good temperature decreases?

[dizmo]

To those of you that have delidded your CPU, did you see decent temperature drops? Most interested for those that use air coolers, the smaller or cheaper the better. 

 

I'd be using the best compound available, but does it give the same drop to all chips, or is it a gamble just like the silicon lottery? 

 

Basically, I'm wanting to use a 7700k or 8600k in an upcoming build. It's a super compact case, so thermals are an issue. Cooler will be a Noctua NH-L9x65. Just seeing if delidding might be a solution, or if a locked chip is in my future.

Yes, (on air- be Quiet! Dark Rock Pro 2)

Also, the after delid ambient temperature was higher by about 2-4*C.

This was in July, and I get the exact same temperatures now, no change at all, it is holding up really well (used Thermal Grizzly Conductonaut)

went from 72C load temps to 56C-64C load temps, so there is around 10C diferance core to core now, but its cooler overall

yes it will have a significant improvement unless ur cpu cooler has reached its peak already without delidding ( such as using an intel stock cooler like linus did coz he dont want ppl to know delidding actually improves temps alot... he knew if he use a stock intel cooler it wouldnt make a crap difference )

Beware that your ability to vent the case coudl be the limiting factor. Even if your 'thermal resistance' from the chip to the air is low you need to vent every Watt of power you put into the chip so keep that in mind. (similar to radiator problem)

Yup.  A drop of 15 - 20 degrees is seen on a regular basis.  Don't expect to get anymore overclocking headroom out of it though.  It's pretty damn nice seeing your CPU temps hovering around your GPU temps though (I'm on water).

im sadly only temp limited but i dont have a delidding tool ( fk the razorblade )  tried it on a vice but the fker wouldnt pop off ( smashed it quite hard and several attempts haha i think my cpu die is GLUED hahaha )

 

i put it in the vice, wooden block and hammered it fking hard but it wouldnt even budge, i think my cpu once got RMA'd and the user who sent it back used friggen superglue haha

Which gen do you have? 
You should check for other users experience before delidding (obviously). Example: Threadripper ... hard to delid, not worth it.

What are the 4 temperatures for? Different runs? I've never ran a stress test before.

What cooling do you use?

Yeah I was thinking of that too. Shouldn't be too bad though, it's a small case and Temps were shown to be decent.

Yeah, I'm not too worried about overclocking. Moreso hoping to lower the Temps while keeping decent performance.

That's for each core

Did you try to heat it up gently before removal?

yeh didnt work rofl

 

this is the only chip i cant delid also, delidded other chips just fine... i tihnk i got the luck of having a superglued one

 

tbh my friend was laughing at my trying to delid that one chip bcoz all the other ones just pop and fixed and i got pissed off at this chip just smashed it fking hard and it still didnt do shit my friend died from laughter and im like WTF FK THIS CHIP BANGH BANG BANG

custom waterloop, but those are the overclocked to 5GHz 1.375V results for my I7 4790K. the waterblock is a EKWB Supremacy EVO which im not especially happy with and i have a 360 and 240 rad and a GPU block

There are two separate gains to be got from delidding. Part is from reducing the IHS spacing, part is from upgraded thermal compound. For the 1st part it depends on how good or bad it was before the delid, and how much load was on the CPU, as more power = more gains. Replacing with another higher quality compound at same time, I've seen drops in ball park of 5C. To get the bigger gains you're looking at liquid metal not conventional pastes. 

[Brett_Bst]

I used liquid Tim and thermal grizzly, 7700K and temps dropped 10-15c, most get from 8c up drops but some people have had hardley any differences, I will say that I'm useing a AIO not air cooler. I wouldn't do it for the 8700K until I have used it and tested it for a while. 

[Simon771]

Usually it helps a lot.

But then again it depends on your current temps. If you have i7 7700k that is already running at 90°C at stock, it should sure drop down to 70°C.

 

I'm still waiting for people to buy i7 8700k, to see how bad are thermal problems with it.
