Not Sufficient Cooling?

[Shrepto]

Recently upgraded my monitor to a 144hz 1440p display and ever since then my CPU has had to do a lot of extra work.  I have a 9600k with a Corsair H115i.  With auto settings on the mobo I was seeing spikes into 80c at the start of games like Apex Legends, hell it hit 82c during the game launch.  This is with the pump speed set to max (actually has a significant impact on temps) and a rather generous fan curve using Noctua fans (static pressure ones I don't remember which).

I don't really think that is very reasonable to me.  I have a Corsair Air540 case with every fan slot populated including an extra one under the GPU as an exhaust (it's an aio GPU as well so that's not putting out hot air into the case).  When I set a V-core to 1.27 and LLC to low my temps drop significantly, at only 65c.  Is Gigabyte's stock settings on their Z390 board just overly ambitious, or is my cooling solution just meh?  I feel like my chip runs very hot, seeing as it also overclocks like garbage so I know I have a complete lemon, but damn...

Sounds like a bad CPU mount and the TIM has finally dried up.  The increase in resolution will not increase load on the CPU, it will increase load on the GPU.

 

I know (from reddit and owning one) that the H100i's mounting backplate can be finicky and cause bad AIO seating issues, feeling like its tight but its really not.

I've remounted this thing countless times now and applied new TP lots, it's not that.

I've read a posts where people were suggesting to use washers on the mounting hardware to increase mounting pressure.

Now i don't own an AIO and i've only ever used one once when i borrowed one from a mate who had one spare, it was a corsair branded AIO that's all i can remember, and the mounting did seems rather loose even with everything tightened as much as possible.

I assume you would put the washers behind the motherboard sandwiched between it and the mounting hardware.

It might be worth googling around to find more info.

So the cpu is prolly hitting close to max usage when it spikes, so temps would go up. What’s the problem exactly? If you are sure the mount has proper even pressure there isn’t a real issue.
