Processing heat levels are increasing.
In most games (besides League of Legends) my CPU operates between 78-85°C and occasionally reaches the low to mid 90s for brief moments. It stays around 40°C during idle. When playing demanding titles like Witcher 3, Cyberpunk or Black Ops 6, my PC gets noticeably warmer. My GPU stays at about 80°C in-game, which seems fine. I haven’t observed a significant drop in performance since, except when the fans get louder. My old AIO stopped working some time ago; I’m unsure of its temperatures then. Now I have a Coolmaster Master Liquid 120. I re-applied thermal paste but didn’t notice any change. Deep cleaning helped slightly. I still use default CyberPower fans and have a Coolmaster fan nearby, though the rear setup looks odd—possibly due to a Molex adapter. I’m worried about making further adjustments.
No CPU details provided. Here’s the full specification list:
Processor: Intel i9 9900K GPU: 2080 Super Motherboard Type: Asus Prime Z390-P ATX RAM Quantity: 64GB DDR4 Corsair Vengeance 3600 MHz
The 9900k/kf is an extremely powerful processor, but a budget 120mm AIO may not handle the heat well during intense workloads. Temperatures around 78-85°C are acceptable, though the mid-90s range feels a bit excessive. I was able to maintain a stable 5.1ghz overclock with the NH-D15, but using the free ML240L coolant from the CPU proved insufficient. Upgrading to a cooler like the Peerless Assassin SE120 would likely result in better thermal performance.
Thank you for your feedback. Your setup involves using a computer that needs significant processing power, and the cooler you found is available through Prime shipping. The Cooler Master Hyper H412R is also in stock with Prime delivery—would you like me to compare it to the Peerless Assassin SE120? Alternatively, the N H D15 offers higher performance at a higher price, while the Cooler Master model could be a solid choice if you prefer reliability over cost. Let me know your priority!
120mm AIOs offer little improvement over a basic single tower cooler. Opt for a top-tier single tower model or combine two towers in your case for better cooling. If you prefer staying with the existing AIO, verify it's functioning correctly and check for unusual sounds during operation. You can also perform a stress test before installing it in the CPU socket; if temperatures drop, your thermal paste may be inadequate.
The quantity of thermal paste applied can affect your setup. Too much paste may hinder its effectiveness. A thicker paste behaves more like an insulator than intended. Opt for a thinner layer if possible. Ensure the paste fully covers the CPU surface. If you notice spillage or issues, clean it with alcohol and try again. Excessive paste can lower heat transfer, cause uneven performance, lead to slowdowns, crashes, and reduce efficiency in demanding tasks.
