Is my overclocked Intel i7-5820k running too hot?

[nern9]

Hello! I have overclocked my i7-5820k to 4.3GHz a few weeks ago, but i noticed that its running at about 52 degrees C when idol. under full load, it only goes up to about 65 or so. Is it normal for it to run this hot when its not doing anything? I have the Cooler Master 212 EVO for my heatsink, and i just replaced the thermal compound, but that only pulled it down 2-3 degrees. Any advice would be greatly appreciated! Thanks!

[Interfectorem]

That does seem a bit high for idle temps but load temps are well within range, so I wouldn't worry about it too much.

The picture you show is not load.

Run prime 95 in place large FFT if you can stay under 95degress or thermalthrottle you're good to go.

52C idle for 1.219v is fairly high, expected would be in the 30-40C range depending on ambient.

 

What cooling solution are you using? Might try kicking up the fan profiles. If you're using an AIO make sure the pump is running at its rated speed.

hyper 212 evo lol....

@OP

Still it sounds like you have speed step disabled or something... And are you using adaptive and not manual voltage?

I wouldn't run Prime95 on Haswell CPU' s.

Why not? A stresstest is a stresstest if it fails its not stable.

It can stress too far. It puts unrealistic loads on the CPU.

Thats the point of a stresstest  you need to know what the max capacity is.

Which is what stress tests do. But Prime95 can be finicky and can kill CPU' s.

When did that happen? also i wouldent run large fft for over an hour for long tests small fft is fine.

[Curufinwe_wins]

Or you can not overkill it (because if you want overkill run some linpack) and just use intel xtu like a sane person...

It's happened to me. Poor, poor Pentium E6300... You will be missed.

Sorry to hear that seems like older generations where thougher.

 

Edit i just realised that cpu is from the same era as my but nothing has ever killed it yet

[nern9]

Sorry, im new to overclocking. Just to make sure im not screwing anything up, heres a screenshot of my bios. Is there anything that you guys recommend i change?

[Dabombinable]

It only kills CPU that don't have adequate cooling to deal with the CPU running the FMA3 instruction set.

Not necessarily. It just pumps the voltage higher than you specified within BIOS. Some CPU' s die before the temps hit unsafe if the voltage just pushes it too far.

[Najuno]

I´d recommend AIDA64 Extreme for CPU stress testing. I´ve been using the software for years already in full version, it gives you a lot of insight and info.

[Dabombinable]

The CPU automatically overvolts by 0.100V to handle the load. Running it my 4790K gets pushed to 137W when it normally goes no higher than 87W with other instruction sets-and that's at 4GHz since the boost gets disabled. Straight up if your CPU isn't Prime95 stable its not stable. Going to another stress test that isn't as intense and calling it a day doesn't make your overclock suddenly stable. And any dead CPU would be from idiots running an overclock that's already close to or at the safe voltage limit with insufficient cooling. Also-all CPU (except those on the AM3+ socket) thermal throttle at the correct temperature when overheating.

Why don't you run linpack instead then? If it isn't linpack stable then clearly it just isn't stable... You see how this argument devolves right?

'I must pass all stress tests!'

This kind of thinking might had merit in previous generation CPUs, but in Haswell at least, it is a load of bollocks. As you can see from my chart below, the range of temperatures vary wildy from test to test. We are talking about a 45C difference in temperatures. If I had stuck to Linpack or go home, I would be down from 4.6ghz to 4.1ghz. (This is backed up by testing.) This is insane. Linpack is so ridiculously hot, so completely out there, it's not worth counting. The mentality of passing all tests for the sake of stability is more irrational than you might presume at first glance. That kind of mentality means passing whatever test people happen to be able to make. If nobody made Linpack, then you would think your CPU is stable. If somebody made Linpack 2.0 that makes Linpack 1.0 look like child's play, then you might as well never overclock, because Linpack is throttling a few people at STOCK. Indeed, Linpack uses AVX2 which is a new instruction set, but so does x264, and that is one of the coldest benchmarks. Stressing AVX2 set doesn't nessesarily mean high temps and failing Linpack doesn't mean AVX2 instability. And how will you know when to stop stress testing under the original ideology? You can only estimate. Computers are built for using, not for stress testing. If you're running Linpack, and you're under the opinion that you must pass all possible tests, you need to update the math logic for Linpack and run it at MAX setting. That means using up all of your available ram for the largest problem size.

 

Run 2-3 different types of stressing programs, and then use your computer normally. If you crash, then it's not stable. What's stable for you might not be stable enough for me. Some people need 100% reliability because of their jobs. Some people can handle a Bsod once a week. NO, saying that you want to pass Linpack 'just in case you use your CPU to extreme limits' is complete hooey. Prime95 is already ridiculous. Linpack is ridiculous on top of ridiculous on top of unicorn blood powered by the core of the sun, worshipped by space aliens. What if there comes out a new normal application that uses as much CPU power as Linpack? Well, there is no hint of that happening, so this is just a 'what if'. Well, what if there comes out a new application that throttles you at stock? Then let's all downclock our CPUs! If you insist on passing every test just because, fine, just don't expect any half-decent overclock. If I hit 95C+ easily at 1.2v with D14, there is no way anybody can hit 1.25v+ with Linpack set to max even after delid and x60 Kraken. And guess what, the average voltage setting for the OC results chart is 1.3v, so what does this tell you? You'll be lucky to stay on 1.25v after delid and liquid cooling and having a stable setting because between Prime 28.3, which discovers stability issues like a god and Linpack at max which raises temps like a god, you will be severely hampered by the combination of both tests.

 

Don't give me that 'If you crash on anything, you're unstable, period' crap. Anything is decided by whatever program people decided to make. And if your definition of the word stable means not crashing in anything, ever, then I don't care about what you call stability. You will never know if something is stable by your own criteria because if you pass Prime for 500 hours, what's to say the 501th hour will be stable? That's right, you stop at some arbitrary time. I care about the computer not crashing often enough to annoy me. And that could be once a week, once a month, once a year, never, every 5 seconds. But as long as I'm fine with it, that's all that matters because it's MY CPU.

That is pretty much just a gimped version of Prime95. If you want to delude yourself then fine. But the only way to be even close to certain that you have a stable 24/7 OC is to run Prime95.

You know it's funny, but my current overclock is actually not even 24 hours stable XTU, because I happen to know from experimentation and well a few 1000 hours of use already, that I have never encountered a stability issue in any game I own or any program I've run (including some that do peg my computer at 100% cpu like MCNP 6).

 

I know I can't do F@H on my current voltage (my PSU also shouldn't be running all my components at full power anyways) but even a bsod every 1000 hours under load would totally be acceptable for my current usages.

 

Because I am a very through person, I know exactly what voltage gets me 24 hours XTU stable and what voltage gets me 24 hours Prime95 stable just in case I start using a program that gives a shit. In the mean time, I will take my better component life (not that I'm concerned about it anyways), lower temperatures (not that they were ever bad, but ocd issues), and lower power bill (not that I'm strapped for cash).

my 5820k runs @ 4.1GHz and gets 30-35°C on idle
