the system is overheating under Dark Rock 4
Hey guys,
This is the second PC I've ever built so I'm still fairly new to all of this. My current build is:
CPU: i7 8700k
GPU: Gigabyte Gaming OC 3080
RAM: 16gb Flare-x DDR4 (3200MHz in XMP)
PSU: Corsair RM 850x
Mobo: Asus Maximus X Code
Here
is the inside of my PC for those curious
I've had the 8700k for a few years now , but I got lucky getting a 3080 last week and replaced my 1080ti with it and started noticing temps getting really high with the cpu. To be frank, it could have always ran hot in the past because I never really took an interest in temps, etc. until now.
I figured I'd try a simple overclock at 4.7GHz and followed this video here

I pretty much followed his settings to a t but had my cores at 4.7 with a voltage of 1.3, but I planned on lowering that until it became unstable.
However, I noticed when playing the Cold War beta that temps would hit around 80-90c after an hour or so of playing and occasionally hit 95c. I then reverted back to the default bios settings just to check temps, and they were still getting around those temperatures when playing. Idle seems good though and is usually around 35-40c. I made sure to re-seat the Dark Rock 4 cooler (there's no sticker so please don't ask that lol), apply new thermal, and dust the fans. Everything still runs hot and I'm not sure what to do. Please go easy since I'm fairly new and any guidance and tips is very much appreciated.
Edit: Another thing I'll point out, it looks like the DR4 fan next to the ram doesn't run as fast as it could and just barely ramps up from idle to under load when gaming. I'm not totally sure how I can check what the rpm for that is or if I can even adjust it.
Edit 2: I tried using SpeedFan to see what the speeds were and
this
was what it showed when running the Cold War beta. Is that a normal RPM speed for the cpu? Also, why were my back and rear fans that are spinning not showing up here?
The bigger sizes are indeed better. The S340 Elite can handle 240 and 280mm front-mount units. The 120 and 140mm versions aren't really worth it unless you require a cooler that fits in a compact chassis. Here are some of the most popular options in both 240 and 280mm variants:
Arctic Liquid Freezer 2
Corsair H100i and H115i
NZXT Kraken X53 and X63
Fractal Design Celsius+ S24 and S28
A few other notable models include:
Alphacool Eisbaer
EK-AIO D-RGB
Lian Li Galahad
There are many choices available, but the Corsair, NZXT, and Fractal models generally share similar pumps.
I was planning to recommend some advice on correct cooler installation and paste application based on the title.
In this situation, you seem to have two fans installed.
Could the front of the case contain vent holes? Maybe additional fans are needed there, perhaps one more at the top or even an AIO?
This isn't about the cooler's performance, but rather the heat being released through it from the GPU.
Are your high temperatures on the CPU matching the GPU load and temperatures?
There are no fans at the front of the case, only a dust filter covering the whole front. Two 120mm fans included with the NZXT S340 Elite case are currently in use (placed rear and top). GPU temperatures are stable, generally staying between 60-70°C during games like Cold War beta, RTX titles, and Control with high settings, while the CPU runs at about 50-60% load and reaches 80-90°C during intense play.
I notice insufficient airflow – the CPU and GPU coolers are functioning properly.
The GPU heat dissipation is higher than with the previous 1080Ti model, and part of that heat must be directed elsewhere, likely into the CPU cooler.
Dark Rock 4 is handling both the CPU cooling and some GPU exhaust. It seems it's working a bit too hard, so additional airflow from you would help restore balance.
The chassis appears to be an NZXT S340 Elite; adding more fans might not solve the issue.
Thermal performance in these models isn't the main concern—similar to other NZXT H500 series, cooling wasn't the priority. You might need to consider swapping the DR 4 with a hybrid cooler or replacing the chassis entirely if you don’t want to modify the current setup.
Since we don’t have the original thermal data from the 1080Ti, it’s worth testing the old unit in your system to compare performance.
Man, you're absolutely right. The Gigabyte 3080 features a special screen cooler on the backplate (right next to the cooler fan) that helps move warm air upward. It makes sense that warm air is being pushed up from the card into the DR4 fan and directly to the CPU. Your temperatures seem to align with that setup. For the 1080ti, I gifted it to my brother because he's starting PC gaming and I wanted him to have a great beginning.
It wasn't just that, but is a given with all the aftermarket models. Notice the orientation of the heatsink's fins at the sides. They are guides for air after the fans have already pushed it through.
It comes out the sides and does 2 things:
-circles downward back into the cooler.
-circles upward and out of the chassis. That some of it goes through the cpu cooler is just a means to an end; it eventually makes its way out of the chassis.
Another potential issue is the lack of exhausts the S340 has at just 2.
Once you've maxed those out, there's nothing else beyond replacing with stronger fans, and they have their own set of problems, mainly noise.
No one can say for sure, because there's nothing to compare to. I'm just using some deductive reasoning.
That's why I mentioned the 1080Ti's thermals earlier. Nothing to be done about it though, so you'll have to work with what you've got.
Hands down, replace the DR 4 with a 240/280mm hybrid cooler. Orient the radiator's fans to pull air through.
If you believe a better cooler would be ideal, I’ll secure one (until I acquire a new case later). For your current setup, what model would you suggest? Also, does the top feature just one ventilation opening for a single fan, and is the rear similar?
The bigger sizes are indeed suitable. The S340 Elite accommodates 240 and 280mm front-mount units. The 120 and 140mm variants aren't really justified unless you require a cooler that fits in a compact chassis. Here are some well-known options in both 240 and 280mm:
Arctic Liquid Freezer 2
Corsair H100i and H115i
NZXT Kraken X53 and X63
Fractal Design Celsius+ S24 and S28
A few other notable picks include:
Alphacool Eisbaer

There are many choices available, but the Corsair, NZXT, and Fractal models mostly share similar pump designs, making the selection mainly about style.
