Monoblock water cooling CPU getting hot. Help please!!!

[UVGamer1225]

Hey Yall. Im new to the site and a total newb when it comes to certian things. One of them being watercooling. I recently just converted over to a water cooling loop. The breakdown of components are:
Gigabyte Z170 Gaming 5 mobo
6700k cpu (overclocked to 4.7mhz)
EVGA 1080 FTW gpu
Photon 170 pump/res combo
EKWB monoblock for mosfets and cpu
EKWB 1080 FTW waterblock
Alphacool 360 rad
Corsair high performance SP120 x3 (Exhausting through rad)
Corsair AF140 x3 (2 inlets, 1 exhaust)

So heres the problem. I am getting temps of 38-40c on the GPU (Awesome!). However my CPU under load is getting like 75-80c! Thats no good! I had the same overclock running cooler on air cooling. Im using 16mm hard tubing so there is no way im kinked anywhere. Also i have a flow indicator showing awesome flow. The path is pump to GPU to CPU (monoblock) to rad to res. I remember when i installed everything that i didnt like the way the block mounted to the CPU. It almost looked like a very slight gap. it was hard to tell because of the way the monoblock fits the mobo and the color of the thermal paste. Is the block supposed to be touching the CPU? I really think thats where my problem is. Im just looking for experianced memebers to give feedback. please let me know. Thanks!!

If the block weren't touching your CPU, it wouldn't be 80c under load, it would be 100c at idle.

Be aware that by putting your CPU in the loop after your video card, it's receiving water that has already been warmed by the GPU. This probably has at least a few degrees C impact. What air cooler were you using before?

So i have been doing some research and am finding these temps only being seen when stressing FPU. Im still investigating but from what ive read so far this test is the most temp increasing test you can perform. So when i test without out using FPU my temps are 55-60c. I believe i just didnt know what i was testing. What do you think?
Also I have read many forums and reviews that indicate that temps only very 1-2c when running after another component. i plan on adding a second rad. At that time ill run: pump to gpu to rad to cpu to rad to res.

In general, the temperatures that matter are the ones you actually get the way you use your PC. It's true that you can get temperatures much higher than you'll ever see during your typical usage patterns by using something like Prime95 or IBT, but what use is that?
