Is my GPU causing extremely high tems in my watercooled CPU?

[ItsMeAro]

Ok, so, I am wondering if my Open Air GPU is causing high temperatures in my CPU.

My CPU is the 6700K at stock speeds, my CPU Cooler is H100i V2, and my GPU is the Strix 1080. Additionally, my case is the H440, which isnt the best for air flow. The CPU cooler is mounted on the top of the case with fans set to push air out of the case.

IDLE:
CPU: 27C
GPU: 35C

CPU STRESS:
CPU: 68C
GPU: 35C

GAMING:
CPU: 88C
GPU: 68C

I was wondering should I do anything to improve the temps or do I have nothing to worry about?

Thank you,

Aro

Well try to put out your h100 out of case and test, whats your room temp?

I dont think the GPU can cause High CPU temp..
I have H100i GTX and Zotac GPU when gaming My GPU temp can exceed 90'c but stiull my CPU temp stays Lower then 65"C

Check if you have properly mounted H100i CPu bracket

Try taking door off case and direct a house fan into case and game, seeing as your stress test(what tests?) temps are good I suspect poor case airflow.

How many and what fans are you using with the H440?

88c is to hot.
