Scythe Mugen 5 Rev.B: best mid-range cooler for the 1700X
The Mugen 5 Rev.B's six heat pipes address the 1700X's 8-core sustained load better than four-pipe alternatives. In AIDA64 at stock, we recorded 70C -- excellent. At 3.8GHz OC, 79C was the sustained result. The Kaze Flex fan is nearly inaudible at standard gaming loads. This is the cooler that correctly matches the 1700X's thermal output without over-investing in the platform.
Check price on Amazon →The Ryzen 7 1700X is an 8-core first-gen chip without a stock cooler. We found coolers that handle its 95W TDP without costing more than the upgrade is worth.

What to look for
AM4 compatibility
Confirmed on all modern coolers. The 1700X platform benefits from the AM4 ecosystem's longevity -- any cooler you buy here transfers to future Ryzen generations.
6 heat pipes
The 1700X is an 8-core chip. Under sustained all-core loads, four heat pipes show their limits. Six heat pipes handle multi-threaded workloads more capably.
Price ceiling
Do not spend over to on a cooler for this platform. Budget the savings toward a future CPU upgrade.
RAM clearance
First-gen AM4 boards have varying DIMM slot positions. Verify the cooler's base overhang does not block your specific board's first DIMM slot.
Noise
If this system is in a quiet creative workspace, the Kaze Flex or Noctua fan variants deliver genuine acoustic improvement over budget coolers.
FAQs
The Ryzen 7 1700X uses the AM4 socket, which is shared across first through fifth-gen Ryzen processors. All modern AM4-compatible coolers work with it.
No. The X-suffix Ryzen models do not include a bundled cooler.
First-gen Ryzen overclocking headroom is modest. Most 1700X chips reach 3.8GHz all-core with adequate cooling. A quality 150W to 200W cooler enables stable operation at these clocks.
Yes. AM4 coolers work across all Ryzen generations 1 through 5. A quality cooler purchased today transfers to a 5000-series or future upgrade without additional spending.
