Delidded CPU Squeezing TIM off Die

[LiquidPanic]

So I delidded my 3770k to get around the horrendous TIM Intel started using after they stopped soldering their dies with Ivy Bridge. Long story short I have had to re-open and reapply the TIM 5 times now just messing around and testing because for whatever reason, though very few other people seem to have this issue, my temps skyrocket back up to and sometimes higher than stock TIM levels after just a couple days. The last time I reapplied it I noticed that there was barely any TIM on the die, it was mostly around the edges, despite my very deliberately spreading out a thin layer right on the die and making sure the whole thing was covered.

 

Has anyone else run into issues like this? At this point I'm ready to put a spacer or something in there to stop my cooler from pressing the IHS on too hard.

ok but why would you delid the 3770K? that chip isnt even that bad, the really bad ones are the 4770K and then 6th gen up, not to say there isnt temps to be found but its really not horrible beyond those. anyway sounds like you are using some really runny TIM, what are you using? could also be that what you are putting on there is just worse also

That's called TIM pumping, it's a problem on normal TIMs used on CPU dies. Use something like Antec Formula 7, IC Diamond, Kyronaut, or a liquid metal based TIM. These TIMs are thicker than normal TIMs and should be good.

Naw any TIM under the IHS can really hurt the speed you can run them. If you're pushing the chip to 5GHz you'd need to replace the TIM

more like if you need over 1.35V than 5GHz, but sure. my 4790K did fine at close to 4.8GHz with defult TIM, got it up 300MHz replaceing it and down a bit in temps as well but i havent seen much of 3rd gen chips or earlier going 5GHz really

Over 1.35v is not that much. I have run my I7 7700K at over 1.6v (on both phase change and custom water) for 6GHz and 5.4GHz respectively, My daily voltage and overclock ranges from 5GHz at 1.32v to 5.2GHz at 1.44v, depends on what GPU I'm using at the time.

yes but i was refering to when its apropriate to rip out the TIM and slap some LM in there, ofc you should if you are going for extreme overclocking lol

Well, extreme liquid cooling, but for phase change, liquid metal is a massive no no. Kyronaut or King Pin cooling TIMs are the two dominant kings. Kyronaut is a really really good TIM anyways on air or water, @LiquidPanic I would recommend that, but the other pastes I listed are good too.

No issues deliding mine. Just had to set a good amount of pressure for when letting the silicon cure after putting the his back on. Dropped about 20c average and used regular tim.

Fist time didn't have enough pressure so only dropped about 10c average.

[LiquidPanic]

To answer everyone at once. I delidded it for a higher overclock yes (4.6ghz with a 4.8ghz single core boost), but mostly for noise as it allows me to run my fans at a lower speed and maintain identical temps. I'm using Gelid GC Extreme under the IHS. For @Bananasplit_00 the 4790k is just a rerelease of the 4770k with slightly better power management and better TIM under the IHS, which is why it would be fine temps wise compared to the 4770k and 3770k. I can see what you mean though @Lord Nicoll, it could definitely be that the mounting pressure is just too high for how runny the TIM is.

As someone who owned a delidded 3770k, the tim was bad. Delidding got me 20C overclocked. 

 

To op, i would suggest putting more paste. Too much tim doesn't itself cause bad temps, but not enough does, so don't be afraid to overdo it. Just make sure it's non-conductive. 

Or just use LM.

I can assure you it's not that I'm using too little TIM. I actually spread it across the die using one of those little spatula things they include with some TIMs. The problem seems to be, from what Lord Nicoll has told me, that the TIM I'm using is too runny. Whenever I remove the IHS to troubleshoot and reapply almost ALL of the TIM is pushed out the sides and there are areas on the die that look like there hasn't been any TIM applied.

Liquid metal could be the solution. Maybe your paste is too runny? What do you use?

I'm using Gelid GC Extreme. It is quite a bit less pasty than the Arctic MX2 I used in my last system.

[Mick Naughty]

I tend to use Artic or the ek stuff. Just used grizzly for the first time as it came with my block. 

 

Own all 3 CPU’s mentioned. Can’t say any have thermal concerns for oc’ing as much as it is being lazy.
