4.6 GHz or 5 GHz?
4.6 GHz or 5 GHz?
I'm wondering if it's worth spending more to upgrade my cooler and hit or even surpass the 5 Ghz target. I currently have an i5 9600k with a Z390 extreme4, decent case cooling, and an RTX 2070. I plan to play FPS games like Fortnite at 1080p 144 Hz. The H7 cooler costs $38 on Newegg, but will it really boost my clock speed enough and improve performance?
The H7 offers great value as a budget cooler, but if you're aiming to maximize overclocking potential, consider opting for a more advanced cooler and possibly a premium motherboard such as an ASRock Z390 Taichi, Gigabyte Z390 Aorus, or ASUS Z390 ROG STRIX.
Keep in mind, though, that results can vary widely depending on the CPU model. Performance improvements usually come in small steps. If you approach overclocking with high expectations for a specific speed target, you might face disappointment.
So you haven't developed the system yet and are seeking some fresh tips? I've heard the noctua is popular, but the cryorig also offers solid performance. The H7 should provide decent oc results, though the noctua might edge out. Regardless, if the H7 maxes out at 4.6, that's according to the specs, it could be a bit of a lottery with silicone.
As mentioned earlier by DSzymborski, it's impossible to foresee how effectively your i5-9600K will overclock. We can only share general information about typical outcomes. Varying by up to 200MHz depends largely on the sample quality you obtain. The process is constrained by two main aspects: voltage and temperature. Just as diamonds differ, each processor has its own flaws that influence voltage tolerance, heat management, and overclocking capability—often called the "silicon lottery." If you prefer not to gamble with your setup, consider buying a CPU that has been professionally delidded, tested, and categorized for specific overclocking. You can find such options at Slilicon Lottery https://siliconlottery.com/collections/a...4952450134 This service delivers excellent results, includes a warranty, and provides an overclocking report. The documentation outlines the necessary conditions and BIOS configurations to replicate those gains, eliminating guesswork or trial-and-error typical in overclocking. When increasing core speed (MHz), the voltage (Vcore) must also rise to ensure stability. This leads to higher power usage, which in turn raises core temperatures. Here are the recommended maximum core voltages for microarchitectures from 14nm to 65nm since 2006: The standard operating temperature range is: Core temps exceeding 85°C are discouraged Temperatures under 80°C are preferred With advanced cooling solutions, you may surpass the Vcore threshold before reaching 85°C. With basic cooling, you’ll hit 85°C before the voltage limit. In either case, the point at which you stop should be clear. Keep in mind the broader context of overclocking. For instance, the jump from 4.5 GHz to 4.6 GHz represents less than a 2.3% increase, which doesn’t meaningfully affect overall performance. Pushing beyond the suggested core voltage and temperature limits offers little benefit compared to the risks involved. Beginner’s guide to overclocking your CPU http://www.

OC gains are hard to forecast and sometimes justified. At 4.6GHz my i7-3770K achieves around 300fps in CSGO, while at 4.9GHz it reaches closer to 350fps. With 60Hz monitors, even on 144Hz displays, the performance gap is minimal. Many games, particularly open-world titles or titles like Civ, depend less on clock speeds and more on core strength, making the jump between 4.6 and 5.0 almost insignificant. Anything above 3.2 should be roughly fair.
For cooling options, both models are decent, but the H7 is still a 145w budget cooler with limitations. At temperatures over 250w, the NH-D15S outperforms it significantly. The H7 works well for light or moderate overclocking, but you won’t get much more unless you rely on earplugs. In contrast, the NH-D15S can handle much more demanding tasks and deliver better results overall.
