CPU gets hot ?
I observed my CPU overheating and experiencing crashes, so I replaced the paste which resolved part of the problem. However, it’s still getting quite hot (over 80°C under load) and reached 90°C a few times. I’m concerned it might stay too warm during heavy use.
The CPU model is Intel Core i5-13600K – a 13th Gen Raptor Lake 14-core processor (6P+8E), running at 3.5 GHz with LGA 1700 and 125W power. It uses Intel UHD Graphics 770, paired with a Cooler Master Hyper 212 EVO V2 cooler featuring SickleFlow 120, PWM fan, and direct contact heat transfer. It also includes four copper heat pipes for AMD Ryzen/Intel LGA1700/1200/1151 configurations.
I purchased thermal paste from Amazon for about $15.99.
Any advice or suggestions would be appreciated.
Your CPU has the potential to reach up to 181W.
The review notes a 150W cooling capacity as the maximum for the Hyper 212 EVO V2.
In the comments, a figure of 150W is highlighted as the upper limit for cooling performance.
On the Cooler Master website, the TDP of the 212 is not explicitly listed, but 150W appears reasonable.
@thestryker shared their experience with the Peerless Assassin, used in two setups, and compared it to more costly models like Noctua NH-D14 and NH-D15.
The 13600K is expected to handle temperatures up to 100°C before thermal throttling begins.
The user questions whether overheating is the cause of crashes, asking about PSU specifications, motherboard VRM count, and XMP configurations.
They tested the 7950X under heavy load for over 36 hours, noting stable performance with a PSU, proper cooling, enough VRMs, and reasonable XMP settings.
They recommend upgrading the 212 to a larger air or 240mm+ AIO model if needed.
When I applied a new paste, it hasn't crashed and the temperatures dropped to around 80 degrees. I tried enabling XMP but the system won't boot when I do, my RAM clock speeds are already optimal so I didn’t check further, just one issue at a time. Everything else worked normally until that point when it started getting too hot. My PSU is an 850 Corsair Gold, but I can’t be sure that’s the problem since before the crashes and system freezes it was stable. I ran some scans on the SSD and memory, and everything came back clean.
Corsair offers a solid reputation, yet the gold rating and 850W output figure seem to represent just the efficiency level and capacity claims. We lack clarity on the specific model or its age. For instance, if it's an older HX series unit from 2010, it falls well beyond its warranty window. https://www.reddit.com/r/buildapc/commen...er_supply/ Other models with 850W include the AX850, RM850x, RM850e, and RM850x Shift. I only repaste my CPUs during heatsink replacement or CPU upgrades. My 7950X has operated for two years and six months without changing the NH-D15, while my TIM My 3800X with an NH-D14 has remained stable for five years and eight months. Both Noctua coolers are dual tower with twin fans, similar to Thermalright units. I still believe your 212 model is somewhat inadequate and would gain from a superior cooler like the Thermalright Phantom Spirit 120 SE. You might also look into a larger 240mm AIO cooler. This is the cooler you currently use. Compare the EVO's four heatpipes and single fan with the Phantom's seven heatpipes and dual fans. The Thermalright model is priced at $35.90 on Amazon.com. Just verify your case height matches the 120 SE's requirements. This site displays the 212's performance relative to the Phantom across different CPU power settings and fan speeds. https://pcanalytics.com/product/coo...r-...it-120-se/ The summary notes: "The graph... illustrates the sound normalized results under the '130W - Overclocked' test using a Ryzen 7 5800X. When examining the chart, the Phantom Spirit 120 SE outperforms in cooling efficiency across all comparable noise levels. The largest gap appears at 34 dBa, with a variance of 7℃. Conversely, the smallest variation is seen at 41 dBa, showing a difference of 4℃." From this, it seems replacing the 212 with the Phantom could lower temperatures by roughly 4℃ to 7℃.

Additionally, I swapped the paste since I previously modified the motherboard and didn't use paste before, which made a noticeable difference. I also bought the cooler that was connected via Amazon as suggested by the earlier poster.
Someone can clarify why your CPU appears to be under heavy load while your GPU stays idle, especially with a high-end RTX 4070 Ti.
