120mm vs 140mm Fans for CPU Cooling
120mm vs 140mm Fans for CPU Cooling
Maybe you should revisit what I mentioned. What I said is that it reaches a limit,
100mhz represents a 2% variation in clock speed for 4ghz. I refer to this as "around," but perhaps your interpretation differs.
I believe you overlooked the key point. Ryzen processors aren't constrained by thermal limits like Intel ones. They're restricted by their design. You mentioned having enough thermal headroom to reach 4.2, but that's not the main concern. The real issue isn't a barrier; it's spending money on something that doesn't exist.
XFR can push your CPU up to 4.1ghz on 1-2 cores, which matches its intended purpose. However, once you start overclocking, XFR is turned off. I think XFR didn’t perform well in the first generation. The goal is to eliminate the need for overclocking altogether. Yet, on the second-gen chips, XFR does offer a slight boost to 4.35 on a few cores, though temperature plays a bigger role now. I'm looking forward to seeing how XFR evolves; it's possible that by the time Ryzen 2 arrives, your CPU might overclock itself.
I would test it using the original fan to check performance. The second fan won't be very effective since the air is already moving, and it's mostly being driven by the first fan. There are 140mm fans with 120mm mounts available.

Or consider purchasing a 140mm cooler.
