Hey everyone! I'm new here and just built my first PC, but I have a few questions about cooling my CPU. I built the system for both gaming and computational chemistry work, so I'm looking to keep my Intel Core Ultra 9 285K CPU running optimally during heavy workloads. Here are my current specs:
- Intel Core Ultra 9 285K CPU
- MSI PRO Z890-P Motherboard
- Noctua NH-D12L CPU cooler
- PNY Verto RTX 4070 GPU
- 64GB 6400MT RAM
I've noticed some high peak temperatures while running benchmarks, reaching around 102C with individual cores hitting 104C. While I've tried undervolting the CPU, it hasn't significantly lowered the max temperatures. I'd love some advice on a few things:
1. What are considered safe sustained temperatures for intense workloads like computational chemistry? I've heard differing opinions about 90C but wonder if that's applicable to gaming rather than heavy CPU tasks.
2. What are average stable undervolt levels for this CPU? I'm considering pushing bigger undervolts as I'm open to sacrificing some clock speed if it means colder temperatures.
3. Is my cooler sufficient, or should I look into upgrading? I initially thought the D12L was fine, but I'm curious if something like the Noctua D15 would provide enough of a difference. I prefer staying away from water cooling but might consider it if it's a significant improvement.
Thanks for any tips!

Those temps are definitely on the high side. It sounds like you’ve already done some good troubleshooting, but here are a few things to check:
- Make sure there's thermal paste (looks like you have that covered).
- Consider your case airflow; stock fans might not be enough for heavy loads. You could benefit from adding more fans.
Letting your cooler deal with those temperatures means something else might be off. Maybe check how your case is set up?
Also, did you remember to take any protective film off your cooler?
For heavy workloads, if you want solid, sustained cooling, I suggest looking into an AIO cooler. They tend to manage heat better under continuous load than air coolers. However, I get it if you want to avoid water cooling. Just know that AIOs have pros and cons too.
What makes you say that AIOs are better? I've heard some mixed reviews on them.
I’ve seen both sides. AIOs can be great but can also experience thermal saturation under heavy loads, while air coolers can handle prolonged use without issues. I'd do some research before switching!
Yeah, I have the stock case fans for now but I'm planning to add a couple more soon!
