i5 7600k "Kaby Lake" safe temperature?

[Umut__]

I just got my brand new i5 7600k kaby lake today. I've installed it with corsair hydro h45 water cooling. when I test it with prime95 for 5 minutes it goes up like 65 degree. when on desktop its around 25-35 while playing games its around 50-55.

my question is I had amd fx 8350 with thermaltake 3.0 water cooling and I've never seen above 61 degree with 10 minute prime95. I am little bit disappointed with intel. btw the performance is incredibly awesome compare to amd.

I thought I installed water cooling maybe bad. re-installed it with brand new thermaltal paste its still the same.

1. - Sorry to break it to you but the low-end water coolers aren't as good as the high-end big air coolers. Just because it's water cooling doesn't mean you should expect amazing performance from it.

2. - 65 degree absolute max temperature is totally fine, 55 in games is actually pretty good.

3. - I would expect the AMD chip to run hotter, this is true, but you had a different water cooler on it, so I guess that's where the difference came from. Was it in the same case with the same setup?

If you want to try to improve temps you can get two fans on the rad, so a push/pull setup. Or are you already running it like this?

65C is good. Yeah Kaby Lake does run hotter, mainly because it uses higher stock voltages than Skylake.

I'd say if your going beyond 75C is when your getting into the danger zone.

Regarding temps compared to your 8350, AMD measured core temp differently than Intel. You can't just compare the two numbers and say that your i5 is running hotter than your 8350.

yes I am using same case but when I had amd I could put water cooling inside the case. but now its out of the case staying on the floor. I want to use 1 more 120mm fan but my mainboard doesnt support more than 2. how can I attach 1 more fan to this water cooler? without getting power to my fan from motherboard .. and when I should be concerned about temperature? I just got this pc and im so exited but little bit disappointed I dont want to use this cpu as long as possible. so is anything below 70 okay?

Intel publishes information on this:

https://ark.intel.com/products/97144/Intel-Core-i5-7600K-Processor-6M-Cache-up-to-4_20-GHz

Tjunction is listed as 100c, and 100c is where your CPU will throttle to ensure stability and preserve longevity. Mobile versions of these CPUs run at 90-95c under heavy load, and show no signs of reduced lifespan. Server versions of these CPUs are often allowed to run at 85-95c under heavy load for years at a time with no issue.

That said, the moment you start adding voltage and clockspeed above stock, Intel's published "100c" figure no longer applies. The combination of temperature and voltage are what degrade and eventually kill your chip, so if you're going to be overcocking, the farther you go, the lower you'll want temps to be.

Just so you know, forum moderator CompuTronix has written a very extensive thermal guideline, which is in a sticky at the top of this very forum:

http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Their recommendation is somewhat more conservative, calling 80c "hot" for an Intel CPU, and it's undoubtedly true that lower temperatures will provide greater longevity, though whether this is relevant to you is another matter. You can probably expect your CPU to last decades if you leave it at stock, but most on here upgrade frequently, so if you subtract 5 or 10 or even 20 years off of the CPU's lifespan, it's probably still going to last longer than you'll keep it.

damn intel is pretty impressive. UPDATE: tested 20 minutes of stress test. maximum 63 degree and it was around 50-55. its awesome but the only problem is now when I launch "core temp" I see power : it goes up like 22 and goes down like 10. when I play games its around 25 and on idle its 10. but whenever this happens my fan goes fast and slow. and this annoys me. is there anything that I can fix it? Like make it stable so the sound doesnt always change and annoys me.

That would be related to fan speed profiles, which you can play with in BIOS. If your motherboard has a value called "hysteresis" you can change, that will be what you're looking for.

Hysteresis - the phenomenon in which the value of a physical property lags behind changes in the effect causing it, as for instance when magnetic induction lags behind the magnetizing force.

In this case, you want a lag in the time your fans spin up, so they don't immediately speed up as a result of very brief changes in CPU load.

...I want to use 1 more 120mm fan but my mainboard doesnt support more than 2. how can I attach 1 more fan to this water cooler?

Look up "molex fan adapter" on google. It plug into one of the big 4-pin connections on your PSU (that would have been for old IDE hard drives or old disk drives) and converts it to the little fan plug. The only downside is that this will run your fan at 12V (100%) all the time, but you can switch over the connectors to get a lower voltage. Use google, my friend. ;-)

This sounds like the opposite of what OP wants. By removing fan speed control, you're either always running it too fast, or making it stay too low under load.

yo dude , i got a i5 7600k too 1 month ago , i paired it with a corsair h60 water cooler , i have been reaching tempratures like 78C . i think your 65 degrees are perfect

I just bought seidon 240v . 2x fans and its the most expensive one cooler and its still reaches like 62 ingame. and reaches like 75 on %100 load for 30 mins.
