I’m preparing a significant hardware refresh for my current setup. This includes a new MOBO, an MSI Z370 PC Pro, a Corsair CX-650M power supply, a Gigabyte GTX 1080 OC graphics card, and an i7 8700K processor. I intend to keep the 8700K cool using a Noctua NH-D15 and their thermal paste, though I’m not sure of the exact temperature target. I won’t be overclocking any components—CPU, GPU, or RAM will stay at stock levels. My case offers good airflow with four 120mm fans, two intake and two exhaust fans. One intake is located at the back of the case directly behind the CPU cooler radiator and fan, while the other is at the top of the case.

I’m curious whether this configuration will be adequate to maintain a reasonable temperature for the 8700K. I don’t typically run highly demanding games; my main workloads are FSX Steam Edition, Prepare3d, and I’m considering X Plane 11 and Digital Comat Simulator. The average room temperature is usually in the low to mid-70s, depending on the season.

Any suggestions or advice would be greatly appreciated.

It seems everything is in order. The Noctua D15 is impressive and likely the top air cooler available. It should maintain a comfortable temperature. The thermal paste from Noctua - NT-H1 appears to be among the best, possibly surpassing that of TG Kryouanaut. The fan placement also looks good.

I believe you should be all right.
Corsair CXm is a solid choice, though upgrading to a higher-quality PSU would make a significant difference.

Thank you for your message. I felt a bit anxious about this, as the 8700k is known for being quite hot, especially when overclocking, and I don’t plan to do that. I wasn’t sure if an air cooler would be enough or if I’d need a liquid cooling system. Regarding the PSU, what advantages would a higher-quality one bring, and do you have any recommendations on brands or models? I thought Corsair had a solid reputation, which is why I chose the CX-650M.

The Noctua cooler is capable of handling medium to high OC levels, which should be acceptable. Regarding the PSU, Corsair offers a variety of models and options. The advantages of a high-quality unit include improved power delivery, stability, ripple reduction, and load balancing. These can serve as useful references: It is recommended to stay within Tier 2.

Thanks for the details, this information is really helpful. It seems my CX-650M is a tier 4 model, which isn’t ideal—it’s just one tier above the "avoid at all costs" lowest tier. I assumed I was managing well with the CX-650M, not pushing it to overclock, and it definitely isn’t a top-tier gaming setup. My budget is starting to feel a bit limited for upgrades without upsetting my wife, who expects me to follow her instructions. I might consider switching to a tier 3 Corsair unit if that’s an option. Thanks again for the support—you’ve been super helpful and clear.
