Very High Temps Water Cooling!? (70-80°C)

VideoklipBG · Jan 10, 2017

Hello Everyone!

I am very confused and decide to ask you for help.

I have CPU i7 6700K 4.00GHz Normal, 4.4GHz Max.
And my Cooler is Water Cooling "Cooler Master CM Seidon 120v - 120mm".

When I stream, play not - Maximum Settings Games (Like CS:GO, Minecraft, Ect.) My CPU Is on 10%-20% Load! This is pretty normal.

(My GPU Is Gigabyte GTX 980Ti G1 6GB Overlocked)

Even When I Streaming on Twitch (With OBS Software on "Medium" CPU Preset) My CPU is 40-50%, to 60% somtimes Max Load.

And the CPU (Via Aida64) shows 68-69°C, Even Up To 86-87°C !

I think this isn't normal. In the Intel's Site it says "These CPUs (i7 6700K) Are up to 80-90°C", but this is water cooling (And it's normal quiet, not very quiet, not very loud. When CPU is on load, I hear the fan a little more, but normal)

AND! - My CPU Is NOT Overclocked on Max! The Normal Clock is 4.00GHz, Max is 4.4Ghz

I Overclocked the RAM (With X.M.P, my RAM is Adata 2666MHz Max, My CPU Uses 2133MHz and I have enabled X.M.P with 2400MHz RAM, My RAM is not hyper overclocked, it's under limit - 2666Mhz)

And the CPU with 100Mhz (Overclocked from normal 4.0Ghz to 4.1Ghz, the Max is 4.4Ghz)

Even WITHOUT Overclocking Anything - It's Very very high temp!

And I want to say - This "PC" is new, from October 2016! I have new Thermal Paste every 2 Months, now It's with new. - And the same problem.

Overall Specs:

● Case: Cooler Master K-350
● Motherboard: Gigabyte GA Z170 - HD3
● PSU: Seasonic X-Series, 1050W, 80 Plus Gold
● CPU: Intel Core i7 6700K, 4-Core, Up to 4.00 GHz
● GPU: Gigabyte GeForce GTX 980 Ti G1 Gaming, 6GB
● RAM: 16GB (2x 8GB) Adata XPG, DDR4, 2666 MHz
● SSD: Adata SX930 XPG - 120 GB, 6GB/s
● CPU Cooler: CoolerMaster Seidon 120v
● HDD 1: Seagate SV35 - 2 TB, 7200rpm
● HDD 2: Toshiba P300 - 1 TB, 7200rpm

So Please Help if someone can! Thank you Very Much in Advance!

what is the CPU core voltage ?
If it's below 1.2v under load, try to reset the MB bios to defaults.

No, the voltage is normal, these temps and voltage are when the PC is not in use (Right Now).
When the CPU is Loaded (10-20-30%) the voltage is 1.224 to 1.230, but the temps are not normal.

50С under load is fine.
Let it run for 15 mins (to warm up the liquid) and see where the temp stabilizes.
if it goes byond 65c, you probably need a better cooler. May be something wrong with it. Like the flow is too low (few reasons for that)

I just clicked "Start Test" and it's not veery hot. When I Render videos (For YT for example), or / and Streaming the CPU is 40-50% Load (Like I say in the 1st thread) and Max 60-70% sometimes, which is fine I think. But when I play for Example Minecraft and Streaming with "Medium" Preset on Twitch my CPU is 55% or 60% and it's over 65°C - 70°C, Even on long Streaming (3-4 Hours) it's Around 80°C, may be little bit lower, may be higher.

I am confused for that - When I just play games, not very heavy, not streaming / rendering / recording. My GPU is around 50-60°C, but the CPU even more than 60°C.

VideoklipBG · Jan 10, 2017

I think my GPU have the same problem, but I am not sure. It's 60-70°C, Up to 85-90°C on some Heavy Games. On non - heavy games it's 60°C Min, 65-70°C Max. When I am not recording / streaming again. It's Gigabyte GTX 980Ti 6GB G1 Gaming, with Overclock on base clock: 20Mhz and Overclock on Memory clock: 50mhz. It's not even overclock, I think it's under limit (In the official website)

On a 120mm cooler you can reach those temps, had deepcool maelstrom 120 and nzxt kraken x31 both 120mm and they could not keep it my 6700k at 4.2 ghz. Now i have a corsair h100i v2 and my temp never go more then 60 degrees at 4.5 ghz.

n0ns3ns3 · Jan 10, 2017

i forgot to mention that poor case airflow might cause the high temperatures.
Have you tried to do your "heavy tasks" with side panel removed ?

Dragos Manea · Jan 10, 2017

n0ns3ns3 :

Doesnt matter, even in open space (how i had mine) it cannot cool enought at a room temp of 27 degrees, my i7 67000k would go into high 80s with kraken x31 at 4.2 ghz with a voltage of 1.27V, for this cpu it would really need a 240mm cooler to keep it below 70.

VideoklipBG · Jan 10, 2017

Dragos Manea - Thanks for the reply, Unfortunately my Case does not support more than 120mm Liquid Cooler (I even thought about Air Cooler, but I don't know the noise, current liquid cooler, which is the problem I think is a bit louder, when the CPU is around 80% Load). I look for not so expensive, but quiet cooler. And to keep my i7 6700K with overclock at 4.1GHz (Even 4.2GHz) without flames

n0ns3ns3 · Jan 10, 2017

120mm RAD is more than capable to keep the CPU cool enough. 240 will just do it quieter.

VideoklipBG · Jan 10, 2017

Yeah, with open case, with cables not in one "Ball" (Becouse I try to make a good cable management and it's pretty nice now), with even a desk fan facing the open case - It's the same, unfortunately.

Dragos Manea · Jan 10, 2017

Depends on your budget look at noctua for some solutions that are into your budget and search online reviews and see how they are compared with the 240mm cooling solutions.

Dragos Manea · Jan 10, 2017

Very weird because i had 2 120mm coolers and none could keep it below 80.

VideoklipBG · Jan 10, 2017

http://imgur.com/a/qPo8V - This is now with Aida64 Around 5-10 Mins on Max Stress. But It's more hot (65-70, even more) whe I Streaming or Rendering sometimes. Not now, It's randomly I think. Yesterday I was Streaming on Minecraft, American Truck Simulator, games like these and the CPU was 70-75°C

this is good, cheap AiO with 120mm rad with excellent performance
Other good options are at least 140mm

On my old PC (Amd FX 6100 3.3GHz, 6 Cores, 4GB Ram, GT 740 Palit 2GB, 400w PSU) The CPU Was with sh*t air cooler ($10) xD It was 50-60°C Maximum on max load

And this PC also working now, but I don't use it.

VideoklipBG · Jan 10, 2017

What do you recommend for liquid cooler (Quiet if it's possible) or any Air Cooler? Like this: http://noctua.at/en/nh-d14/specification I hear that Noctua are good in air coolers, but I don't know what to get. I think liquid coolers are best, than air, but depends on the brand.

This is my GPU on Max Load with Unigine Valley Benchmark Ultra Settings, 1920x1080 Antialiasing: 8x
The whole time the GPU Was 70-75°C + and I don't know is this normal or not.. But.. Here are results (Download vai File Dropper)

noctua are great coolers, it's just i don't like those huge pieces of metal hanging on MB and blocking access to RAM etc.
I personally don't like the sealed AiOs due to many reasons.
the one that will fit into your case, is what i posted above Arctic Liquid Freezer 120.
If you could fit 240mm rad, there are Swiftech AiOs (quiet, excellent performers and affordable) http://www.swiftech.com/aio.aspx
Or EK Predator 240 - a bit more expensive, but much more convenient with cabling https://www.ekwb.com/shop/aio/predator
