h110i re apply thermal


fun

Recommended Posts

how to know if i apply thermal paste correctly?

 

using arctic mx-4

i5 6600k 4.5ghz turbo at 1.264-1.280 adaptive.

h110i extream

 

monitor software im using hwmonitor and corsairlink.

 

core 1 (53c) core 2 (56c-57c) core 3 (50c) core 4 (49c) hwmonitor

 

corsairlink software same result but core 2 (54c)

 

is this normal?i try re sit the cooler and reaply 2nd time still the same.

 

core 2 always higher 2c or 3c. so far i test in gaming only,mafia 3 and csgo both cpu intensive game.

I have an overclocked 6600K and the difference between the hottest and coldest cores is between 6 and 9 degrees, which research on the internet suggests is not that unusual. If those temps are whilst the system is stressed, they seem to be ok, mine goes up to 60, what are the temps at idle and what is the room temp?

 

Link doesn't play well with other monitoring software, so you may be better off if you just use either Link or Hwmonitor. You can use them both, just not at the same time.

thats the max temp on hw monitor,during load test on prime95 core 2 also get 2c-4c more than other core when max.ambient i think aorund 25c i live in malaysia hot in here.wierd why prime95 spike my voltage on manual.btw my corsairlink profile is quite and fans i set base on coolant package temp.

The fans and coolant will have zero effect on core differential. Most CPUs have one core that is predominately warmer than the others. This can be because of the physical chip layout or in more rare cases because of less than perfect construction. Either way, there isn't anything you can do about this with cooler function. The TIM application can affect core differential, but the die size on 6700 is so tiny you would have make a colossal mess of the whole thing to cause the problem. Even a random blob with no planning would likely cover the entirely of the four cores. Pretty much every person I see coming to forum with a 6700K has one core above the other three and from my casual perspective, it seems to be the #2 core. Other Skylake owners are welcome to add in and I imagine there are a lot of people who have asked this same question in some forum or another.

 

On a separate note, if you want to use Package temp for fan control that is up to you. However, that was not the intended design and if you get tired of the fans racing up and down all the time, switch it back to H110i Temp. The coolant temp is a steadier variable that will result in more even fan speeds. It also reflects what the fans actually do, remove heat from the water, not cool the cores directly. For Malaysia or anywhere else with a warm climate, you will likely need to create a custom fan curve. The default curves were all designed with a 20-23C room in mind and you likely won't have that often. You don't need super high fan speeds. Take note of your normal max H110i temp during gaming (or whatever) and set that to the highest speed you are comfortable with in terms of noise. You can then give the curve a lift to high speed past that to let you know when things are not normal.

I seem to recall that Prime95 causes problems with Skylake by boosting the voltage and therefore it is better to use a different stress test such as Intelburn.

 

25 degree ambient won't help, as your idle is likely to be 6 degrees above that, putting you at 31 before you do anything.
