4770k stock cooler performs well under extremely high temperatures.
The core i7 4770k hits 100 °C during Asus realbench. The BIOS is default with stock settings. Temperatures fall to 35°C idle and 70°C load after installing the cooler master napton 280L. I attempted a 4.2ghz overclock but it remains unstable below 1.3 vcore. Could this mean a faulty chip? It's still under warranty, so I can return it, but are the high temps enough to justify a replacement request?
Would you consider sending it back? The 100 C stock price seems elevated even without overclocking.
You can't RMI a chip because it doesn't handle overclocking well, only if it functions properly.
Anyway, trying to overclock automatically voids the warranty.
I had a bad luck with a CPU a few years ago—my 3570k runs on a good motherboard with a powerful cooler, but it caps at 4.1GHz.
Just have to accept it, can't always be lucky.
I understand you're asking about the RMA process and whether a 100°C stock setting is appropriate. It's okay to have questions about this.
You could achieve an overclock up to 4Ghz at 1.3V. That would still result in a quite powerful system...
My chip thrives at 100C with 4.5Ghz, though I avoid letting it reach that level because it requires 1.35 volts. Instead, I opted for 1.3 volts at 4.3Ghz. This setup results in peaks around 71C, paired with a robust water cooling system. As mentioned, 70C under load is a solid performance for an i7-4770k, offering a safe margin for daily use up to roughly 85C, leaving some flexibility for overclocking. If it's a new buy, consider swapping it for an i7-4790k and stop using it. It comes out at 4.4Ghz right out of the box.
The information about 4.2 ghz at 1.3v being safe for continuous use with temperatures under 85°C and its effect on CPU lifespan is not present in the provided context.
