Cryorig R1 Universal Dual Tower CPU Heatsink with XF140 and Xt140 Fans

I am using the Cryorig R1 Universal on an Intel Core i7-6700k processor, on an Asus Maximus Hero VIII motherboard. The cooler fit is perfect and provides just enough clearance (about 1/16") for the 4 sticks of Crucial Ballistix Elite DDR4 RAM which has somewhat tall and fairly wide heat-spreaders. Plenty of clearance for the side panel of the CM Storm Trooper case as well.At stock speeds, I'm getting 28 Celsius idle temperatures, and during heavy loading with stress tests, the CPU maxes out at about 67 Celsius. When overclocked to 4.8 GHz, idle temperatures raise to 34 Celsius and 72 Celsius respectively. Note the maximum temps are under heavy stress testing that is not indicative of normal use. Under normal use during gaming or processing and transcoding high-definition videos, CPU temperatures average 48 - 50 Celsius. These temperatures are achieved while letting the motherboard handle the fan PWM tasks on standard speed control settings.Installation was easy and quick. The provided alcohol pad, thermal paste, and screwderiver was a nice touch. Everything provided made for a simple installation with no extra parts or tools needed beyond what Cryorig provided.The fans are virtually inaudible inside the case with the computer running. The entire system is so quiet I have to press my ear to the case in order to hear any sound from the system at all.The fit and finish of the R1 Universal cooler is excellent. It is truly a gorgeous looking cooler as well, I have gotten nothing but compliments on how nice it looks. So it looks great and performs excellent too. I couldn't be happier with it.

The media could not be loaded. Easy to install. Works well, runs quietly, & maintains low temperatures on my CPU. i7-8700K not delidded, with profiles to run at 4.2 GHz, 4.5 GHz, & 4.8 GHz according to needs. Using the included CP7 Thermal paste. Ambient temperature of my house is 24 C. Idle temps are 33-35 C & under load 40-45 C. Will run stably at 5.0 GHz where again the idle comes up a bit to 38-40 C & under load 48-50 C, but I don't see the point in stressing the system that hard all the time.The system (built 2018) mainly for gaming with workstation, video editing, & streaming capabilities:Corsair Carbide Series Air 540 High Airflow ATX Cube Case with Corsair High Airflow AF140L fan x33 Noctua NF-F12 industrialPPC-2000 IP67 PWM 120 mm FansASUS ROG Strix Z370-E Gaming Z370 ATX MotherboardIntel Core i7-8700K @ 4.8 GHz on 1.25VCryorig R1 Universal Dual Tower CPU Heatsink with XF140 & Xt140 FansASUS ROG Strix GeForce GTX 1070 Ti 8GB GDDR5 Advanced EditionCarbon Fiber Graphics Card GPU Brace SupportPCI Slot Bracket holding 2 Noctua NF-F12 industrialPPC-2000 IP67 PWM 120 mm FansCorsair Dominator Platinum RGB 64GB (4x16GB) DDR4 3200MHz C16 on 1.29VEVGA Supernova 850 P2 80+ PlatinumASUS BW-16D1HT Blu-ray burnerSamsung 960 PRO NVMe M.2 512GB SSDaddlink S70 2TB SSD NVMe PCIe 3x4 M.2 2280 Internal SSDSeagate FireCuda 2TB Solid State Hybrid Drive Performance SSHDSeagate BarraCuda Pro 10TB Internal Hard Drive Performance HDDDEMCiflex Dust Filter Kit Corsair Air 540 (8 Filters)Dell Gaming S2716DGR 27.0" Screen LED-Lit Monitor with G-SYNCLogitech C922x Pro Stream Webcam

Not compatible with a Gigabyte X99-SLI motherboard due to memory card interference. Really disappointed because I researched this as best as I could to try and avoid this. Now it is just a pretty boat anchor.

Pros:Easy to install.Excellent Cooling.Looks awesome.Cons:The 25mm fan makes a slight clicking sound, and the 15mm fan is a bit noisy (typical of thin profile fans)! In the end, they're alright and get the job done, and as long as your computer isn't up on a desk a couple feet away from you (like mine), you'll never notice them. I just replaced them with ones that sound nicer!
