Phanteks PH-TC12LS CPU Cooler Review: Low-Profile, High Value

« Installation Procedure and Clearance Issues | Final Thoughts »

Test System and Benchmark Results of the Phanteks PH-TC14S

  • Ambient temperature monitored at case intake and temperature Delta was used.
  • All case and heat sink fans were benchmarked with fan control settings disabled and running at 100% unless otherwise specified.
  • Intel integrated video is utilized to eliminate additional ambient heat source from discrete graphics cards.
  • Temperatures are averaged (last minute) from individual core temperature results monitored by AIDA64 after 15 minutes.
  • Stock settings have all power saving features enabled in the motherboard with Vcore set static to 1.1V and set to “Balanced” in the OS.
  • All tests were taken at least three times to get the final result.
  • Note that performance results on this setup are not directly comparable with any benchmarks from previous reviews as the UEFI BIOS on the motherboard has been updated and now has a much tighter control on the Vcore voltage.
  • Since it is an ASUS motherboard, it engages all cores when it turbos so temperature will be higher compared to other Z87 motherboards that do not by default.
  • An American Recording Technologies SPL-8810 was used for noise level measurement in dBA, 20CM away from the center fan intake.

Performance Summary:

With the stock Intel i7-4770K cooler as the reference (which actually tops out at 99C), all the other aftermarket coolers understandably fare a lot better. Not surprisingly, the thermal performance lines up with their respective sizes as well with the smallest Noctua NH-L9i sitting closer to the reference and the largest 140mm Raijintek Pallas low-profile cooler at the top. The Phanteks PH-TC12LS bests the Deepcool Gabriel by 8C and manages to run quieter as well.
