Delidding i7 4770 non k

[sparkdh]

I live in a warm region (34°C max room temp in summer). My CPU i7 4770, with stock heat sink and fan used to touch 99°C while rendering 3D models. Now i have installed CM hyper Tx3 evo and CPU maxes at 78-82 °C, which i am still uncomfortable with. At these temperatures the copper pipes are relatively cold to touch (as compared to my gpu heat pipes which are hotter when it is at 72°C, at full load, GTX 650ti boost) This makes me think heat transfer between CPU and heat sink is the bottlenecking the cooling process. Case ventilation is good, and thermal paste under heat sink is fine too ... I think the TIM under the heat spreader + gap between die and IHS is responsible for high heat.
Should i go ahead and delid my CPU , and if i do so, the best paste i can use is Noctua nh-t1 or AS 5 for IHS as well as heat sink (coollab liquid and other good componds are not available in my country). Or should i be happy with current temps and not risk damage while delidding ??
From all delidding methods, i find vice only method easiest and least risky.
Has anyone delid a non k haswell before ??

* additional info: CPU idles at 38-45 °C with temp of all cores unsettled and varying constantly within the mentioned range. GPU idles at 36 constant and no constant variation in temps.

80 C is nothing to worry about. Don't delid, you might break the cpu.

Tjmax is 100C. So 80C at peak is relatively cold, specially with a 34C room temperature. Remember its tested for warranty at 100C for 3 years straight. And you cant damage it due to heat. Your worst experience would be throttle above 100C.

Also you cant compare your GPU with your CPU. They measure it completely different. And your GPU, if measured the same way, may be much hotter than your CPU.

Thanks for the reply .. So ill be happy with 80°C

You dont need to be told to be happy with the CPU temps, that is a high temperature regardless and you should aim for you hardware components to be as cool as possible within reason.

Only the mediocre will suggest you to stay put with such temperatures (and oddly, the very same people that suggests you to stay away from AMD's GPUs because of thermals when those chips have the same if not higher Tjmax, but that deserves another thread) when it is known that having unneeded higher temps in your system leads to higher operating voltage needed for stability, more power consumption, more amperage needed and in turn higher VRM temps, which lead to worse MOSFET efficiency, etc.

If you have a vice and are patient enough to learn the vice-only method (no hammer needed) I would suggest you to do it. Nothing but good things can happen from having better temperatures in your CPU. Also you dont need to run your CPU without the IHS, just tighten the gap between the die and the IHS with a better TIM and you will still be a lot cooler than with the crappy thermal interface Intel ships their mainstream chips. Going direct-die contact with your heatsink is even better, but you have to be careful of the mounting pressure and the weight of your heatsink there. Would be lovely that someone copied the MSI delid guard design and started selling their own (I would probably model and 3d print my own if I happen to get the masurements right )

EDIT: Loved that ninja edit "cold"----> "relatively cold". If only you did the same with every post that is flooded with unneeded hyperboles...

34 c is puny; 42c is hot.
dont delid. you cant OC, so you dont need the extra headroom. if you are so keen, you could undervolt the cpu,meaning, you reduce the amount of voltage that the cpu gets at stock speeds; generally, they will gladly run on less voltage than specified by Intel.

i delidded my 4650k, and *slightly* scratched it. no damage, but about 1mm away from bricked.
dont do it.

- You should have RMA'ed it cause its obviosuly defective.. No way a stock desktop haswell should throttle under load .. thus it must be defective and you're entitled to a new non defective part. (bad news is the next one will throttle too .. and the next and the next.. haswell is a legendary throttler unless you apply extreme cooling or, as you suggest, delid.)

Funny how some people are moaning over ie. iphone6 sustained performance while being totally blank on top notch desktop parts doing the exact same.

He can't even overclock though. Risking killing the CPU outright while also voiding the warranty without really getting anything out of it is flat-out stupid. DigDog's suggestion of undervolting is infinitely better.

Also, AMD and Intel don't have their sensors in the same place.

OP never said they were throttling. Are they?

I'm going to say don't delid. Honestly, that's the correct answer for most people, even if they are ocing. What you gain is trivial and what you risk is a reasonably expensive CPU. Also, even if even goes perfectly for warranty is then toast.

I *almost* destroyed mine once attempting to delid , I was incredibly lucky that I didn't.

Even the vice method has a *certain* risk to it.

A working CPU which get's "a little hot" (and 82C is nothing to really "worry" about) is better than a €330 paperweight. (Yes weak Euro, those CPUs are very expensive currently, even the old 4770k).

And yes I also didn't expect that I would have any troubles delidding, but online videos etc. often don't show you that it's a rather risky thing to do.

You have to make this decision. I made mine. I am glad I have a working computer and I don't care about high temps during stress testing when otherwise the CPU barely reaches 80C. If I were really worried about, say, 5 C or 10 C less I would *probably* look into water cooling. Even then, what do you really "gain" from 10C less? Yes, 10C is "great" but it's only in your mind, it doesn't make your comp better, faster etc. (I also established that delidding would only enable me to up multi one notch, so I would, at best, gain 100mhz at reasonable voltage otherwise I would already be at 1.45V..in other words: Delidding would not turn my CPU into a great overclocker, this is another criterion that I dont delid)

Actually, it didnt go that high right from the beginning .. When it was new 2 years back, temps were in high 80s .. And when i searched on the internet , i got results saying those are fine temps for stock cooler. I didnt check temps for last 1 year as i had not changed cooling fan configuration. But now when i checked, temps went up to 99°C and dropped only to 97°C after cleaning and reseating the stock heat sink with fresh TIM. And after getting CM hyper tx3 evo , temps came down to 82 max

CPU temps look fine. I have the same temps idle and load. Why risk demolishing it?
