From the title itself, it's seem unfair to compare Enermax T40Fit (dual fan) vs Cryorig R1 Ultimate. These 2 parts are from different tier according to this tier list, T40Fit is in tier 6 and R1 Ultimate in tier 2. And the price of R1 Ultimate is more than twice of T40F. Here in Indonesia, best price for T40fit is around 35 USD, and R1 Ultimate is around 82 USD (1 USD = 14481.75 IDR). Anyway here I just want to share what I got by upgrading T40Fit to R1 Ultimate. Maybe this is useful for somebody out there. My build for this comparison: i7-6900K RAM Corsair LPX DDR4-2400 32GB (4x8GB) ASUS X99 Sabertooth MSI GTX 1080 Gaming X 8G PSU Corsair HX750i Case: Corsair Carbide 400C Fan: 3x12cm at front (pull), 1x14cm at top (push), 1x12cm at back (push) Thermal paste: Arctic MX-4 Test condition: Tested using AIDA64, stress on CPU+FPU+cache+GPU for ~30 mins Temperature read from AIDA64 on CPU Package Hyperthreading: OFF Inter Turbo Boost 3.0: ENABLED Tested each in 2 freq: stock (auto freq, XMP: OFF) and overclocked (at 4.2 GHz, XMP: ON) Tested each in 2 time: after midnight (room temp 25-26 C) and afternoon (room temp 30-32 C) Room temp measured using desk digital clock+temperature+humidity, put in front of case (the manufacture said temp accuracy is 1 C). Sorry, no air conditioner in my room... All fan curve tuned by AI Suite 3 (thermal tuning). That's the point, right? I don't want to run them in constant full speed, because it's not the real condition when I use it for work and gaming. Result: Discussion: Yes, your cooler performance is very dependent to your room temperature. As other electronic products in this planet, twice the price doesn't mean twice the performance. If you work in controlled room temp, and you can maintain it below ~30 C, Enermax T40Fit dual-fan is "enough" even if you overclocked it to 4.2 GHz, as long you can provide enough air from inflow/intake fan. Maybe you need to upgrade to tier 1 or 2 air cooling products if you want to overclock more, or if you are working in slightly hot room. Not temperature-controlled room, usually have more dust. Air cooling is better option since it easy to clean, assemble and disassemble, troubleshoot, etc.
