watercoolig Problems with watercooling loop/temps

[Mufflen]

Hi, I am looking for help to fix my loop. I am running an Intel i5-8600K with a custom EKWB loop, and I am having some problem with heat. When idle, the CPU is between 37-45 degrees Celsius and when under load (in a game, around 80%) it is between 50-68. I am running the system with a small overclock to 4,4 GHz, and when I have been playing a game for a long period, my CPU (under load) hits around 70-75 degrees Celsius. For me these temps. are a bit high when running a 240mm radiator, although overclocked, it doesn’t seem right. Anyone having experienced something like this before? I have tried several things to fix this problem, and my config now seems to give me the best results, but still a bit high in my opinion (picture shows config).

If anybody have some great ideas or tips to getting the temps. down, it would be much appreciated 

My next step would be to take the entire loop out, drain it and start all over again, but that seems like a big undertaking.

 

I have attached some pictures of the loop config. Red arrows shows water flow, green arrows shows airflow (i have a 140mm fan in the front)

Is this an EK SE radiator? The temps sound about right to me since you have severe impedence of airflow on the second fan. I used to get 75 degrees on a 8700K on a 240 mm radiator using RealBench. The next obvious step to drop another 15 degrees or so would be to delid the CPU

Thanks for the quick response. Yes it is indeed a EK SE radiator. Is deliding the CPU difficult? I have seen sevearl vidoes on it, but have not had courage to do it yet. Any thing you would recommend  if i choose to do it?

I always had the right tools so for me it was easy, my personal recommendations are:

 

- Get a proper tool, I used Der8auer Delid-Die-Mate 2

- Use liquid metal, I used thermal grizzly conductonaut

- Don't use too much, but also don't use too little. I've put pictures of my application below

- Apply liquid metal on both the die and IHS underside

- I personally don't bother with conformal coating

- If you have a proper tool that comes with a pressure applicator, I would glue the IHS back on with UHU silicon.

- Use normal thermal paste for the IHS to waterblock interface (i.e. liquid metal only for the die)

Going off the build it seems right. Especially the fan orientation. 

 

No info on on ambient temps, pump/fan speeds for the curve. Aside from dropping voltage or a delid, it’s where it should be.

Thanks for the advice, maybe a projekt for the future :)

I agree, the temps are where it should be. Just wanted to clarify that it wasn't too high, which it seemed, but now i have a better understanding of the temp. range. Thanks the for the response btw
