(english is not my main language, sorry about any mistakes)

So guys, i was wondering.. I'm thinking about getting a i7 7700K, but i really dont know which cooler to buy.. Can you guys indicate a cooler that carry the i7 in a good overclock without putting my house into flames? I head about the overheating of this CPU and i'm pretty afraid of it.

A good AIO or beastly air cooler like a Dark Rock Pro 3 or R1 Ultimate/Universal. 


Maxwell is still awesome, and so is X58. If you wanna discuss the X58 platform and get tips and advice: General X58 Xeon/i7 discussion. If you want to discuss old Star Wars games like Battlefront II and KOTOR, check out my thread: Anyone still playing old Star Wars games? 

 

Long live his RGBness, @Damascus! And Fractal Design/SeaSonic dude, @Ordinarily_Greater is awesome as well! Also the man who introduced me to the glorious XCMR, @WhisperingKnickers.

Storage: HyperX Fury 120GB SSD
Storage: WD Blue 1TB HDD

More storage: 2TB something or other drive lying around. 
Video Card: MSI Gaming 980 Ti 6G

2012 MacBook Pro (Work): 2.9GHz i5, 16GB RAM, 525GB SSD. 

 

iPad Pro: magic (and you can't open it up to disprove it, as it's glued shut). Jk, it's got an A9X with 4GB RAM. I didn't need it, so I surrendered it to my Mum.  She never used it so It's mine again. 

 

iPhone 6 Plus: more magic, with an A8 and 1GB RAM.

I've read delidders can get a 20c drop just replacing the Intel mayonnaise under the IHS

If you want the best chance of hitting 5GHz, I suggest delidding the chip. Pair that with a good cooler with a bit of luck from the silicon lottery and you're basically there.

I delidded mine and dropped 10C, not that temps were horrible to begin with, but I wouldn't bother getting an AIO, they don't cool that much better than a big air cooler like I have. 5GHz is going to depend on a good draw from the silicon lottery though.

I can get 5ghz on my 7700k, but it get uncorfortably hot(85C) even with a EK Supremacy EVO...

 

IMO you're likely to be limited by the TIM lottery(its actually a thing with the 7700k) than you are going to be limited your cooler. Of course, if you plan on delidding then you should probably be getting a pretty beefy cooler.

 

I would suggest one of the high end dual tower air coolers(Noctua NH-15, Cryorig R1 etc.) or a 240mm+ AIO.

There's no TIM lottery really... all 7700k's will run hot when pushed to their limit if not de-lidded. The de-lidding process itself can have a variable effect though, and I have seen some only get around 10c, with others reporting over 20c.


My rigs:

Custom Loop - InWin 303 - 6800K - EVGA 1080 - 32GB RAM

Custom Loop - Evolv ATX TG - 6700K - Strix 1070 - 32GB RAM

Admittedly, my research is anecdotal but I have seen people getting very different temp out of the 7700k while running similar voltages and cooling solutions. I am not even the first one to suggest that the amount of paste and distance between IHS and die, might be slightly different between individual chips and be influencing cooling performance.

 

For instance, I'm putting around 1.3v in the 7700k to ahieve 5.0Ghz, and getting the aforementioned 85C. I have seen plenty of people getting similar temperatures with a custom loop as mine, and I have seen plenty of people getting better temps with an inferior cooling solutions.

There are of course a ton of variables that I cannot know about when looking at these results, so every conclusion should be taken with a grain of salt.

 

My main point is this though: You cannot be sure that you will get better cooling performance on the 7700k with a beefier cooling solution. But you might.

Valid, and I'm sure not all CPUs are created equal, but the way Intel put together their CPUs is simply not conducive in and of itself to low temps when they are overlocked. I would say that case, fans, your chosen cooling solution and a host of other factors are going to impact temps more than the CPU itself.

Well I agree. But I'm getting the impression that if the CPU is a 7700k, the CPU itself matters a bit more than if you have 6800K for instance. It might just be because it runs so damn hot in the first place.

 

I have no hard evidence for this though.

Yes, they do run hot... which is why de-lidding is a good idea... but that voids warranty of course. And now Intel have said people shouldn't overclock their CPUs, despite paying more for the 'K' version in the first place so that they can do precisely that. Great job Intel, great job. :dry:

The 7700K is an absolute thermal beast, to put you into context, I ran a short Realbench run on my "almost 5 GHz" chip (somehow the new Realbench always down clocks my multipler by one, weird). I can get a stable 5 GHz, but with a bit more voltage than I'd like to be honest. I am rocking a delidded chip with conductonaut with a full custom loop (albeit, quite a packed one with 2x 1080s).

 

I also ran the fans at max rpm so that it may be easier to reproduce for others. You can see that compared to idle at ~40 degrees, the load temp is at 75 degrees or so.

 

Of course it is possible that my chip is hot, but I think most 7700Ks are comparable.

Maybe they want to limit the K CPU overclock and make a super K model where they charge you even more money to get a useful overclock. Hahaha

thank you all for the answer, but im really noob when it comes to this much technical skills with CPU.. delidding the CPU.. i dont know.. is probably not the best move for me. If i get a nzxt kraken x61 280mm AIO or a Dark Rock Pro 3, not delidding the CPU, should i be fine at 4.8 ghz?

The TIM itself isn't that bad (it could certainly be better, but Intel likely made their choice in choosing longevity over raw thermal conductivity); it's also contributed by too much of the black silicone adhesive (thus creating more gap between the IHS and the die).

You will probably be fine at 4.8 GHz with those coolers. You might even be able to go higher, but as mentioned earlier it's hard to say.
