Am I doing something wrong here? (13700k Gaming Temps)

[Ablindrhino]

After a night of running MW2 on my new setup HWMonitor measured my max temperature for my cpu package at 89C. I am aware that this cpu runs very hot, but that seems a bit excessive.

 

My Specs are:

 

CPU: 13700k

Mobo: MSI Z690 EDGE WIFI DDR5

Cooler: H150i Elite LCD 360mm AIO

RAM: 32 GB 6400 MHz DDR5

GPU: MSI Gaming Z Trio 3080

PSU: HX1200i

Storage: 980 Pro 2 TB

Case: Lian-li O11 Dynamic

Windows 10

 

Currently I do not have the thermalright cpu frame but plan on acquiring it.

 

Top is configured as exhaust with the radiator and included ml120 rgb elite fans

 

Side is intake with 3x ll120 rgb fans

 

Bottom is intake with 2x air series sp120 fans

 

 

I have not touched bios, all drivers are up to date. I have all case fans running at about 1000 rpm as well as the radiator fans as I am a bit sensitive to noise. Gpu fans are running at about 1600 rpm.

 

Any suggestions as to how I can fix these temperatures? I know my fans aren't working very hard but surely I shouldn't be this high right?

Yeh, that is way to toasty especially if its all running at stock speeds. I wouldn't even expect to get that hot when OC'd.

 

Try removing the AIO block and look at how the thermal paste is spread on the CPU IHS to make sure the block is making good contact. Re-apply any paste and reseat.

 

89C at Stock must be that.

Got almost exactly the same setup as you except I run the AIO as intake on the side, CPU temps while gaming are under 75.

 

As exhaust, your AIO is using ambient case temperature air for cooling. When you're gaming, especially with a high end GPU, the GPU will be exhausting a shitload of waste heat into the case (320-360w at stock for a 3080), which your radiator will be (trying) to use to cool the water. It's doing double duty of trying to cool the water and exhaust that GPU waste heat.

This is like turning on your oven and using that to blow directly into your AC system to cool your house.

 

Rule of thumb is intake is better for the thing being cooled by the AIO, exhaust for everything else inside. For a gaming rig, set it up as intake always. The CPU won't usually be running an all-core load enough to affect internal case temps meaningfully, compared to the alternative. You will have short bursts of high CPU load, but otherwise, the radiator as intake is not doing much. But the other way around, you're choking out your CPU with guarantied high GPU waste heat.

 

And if the game you're playing is very CPU intensive, then it's even more reason to run it as intake. Actually, I can't think of any reason to run as exhaust unless you have no other choice.

Thanks for the lengthy reply. As an electrical engineer, you think I would have been able to see the fallacy in my setup myself, but I guess you are right that even with the side intake, at best it is getting 50% clean air and 50% hot air. I don't have any thermal compound on hand at the moment and also have 3 phanteks t30 fans on the way, but do you think flipping the side fans to exhaust and the radiator fans to top intake would rectify some of the issues for the time being? When I get those new fans in I will likely place those fans on the radiator, put the radiator on the side as intake, and have the ml120s as top exhaust and the bottom ll120s as intake. Also for the fans on the radiator is it best to have them side panel side or internal side?

I will say that when I was trying to align the block so that the screen wasn't crooked, I did have to unscrew the 4 mounting screws a few times and kind of "shift" the block. You think that there is a possibility I really messed up the thermal paste application doing that?

It could work, only one way to find out!
