    Every window except one freezes

    What are the system specifications, what game(s) and random background application(s) have you observed this issue happen with? Does task manager still work when the windows are frozen?
  2. There will always be some sloshing, I have never seen an AIO that had completely displaced all of the air in the loop with the coolant. Does it feel/sound like it is more air or more water? If the air from the radiator isn't getting warm then the cooler may need to be replaced. Double check that the pump RPM readback in the BIOS is actually for the pump. It might be worth installing Corsair Link if you haven't already to double check in there. If the radiator is laying horizontally mounted at the top of the case exhausting upwards then a typical air pocket in the loop would spread out in the top of the radiator and have minimal overall effect. If air got into the pump, the pump will often be unable to displace it, giving the loop a shake with the radiator at the top can help displace an air bubble and prime the pump. This would likely only be a solution if the cooler had stopped working properly due to the air being moved into the pump when the cooler was removed for cleaning, and not likely to help if it was faulty beforehand. If the cooler is within its warranty period it would help to contact Corsair to request an RMA if you haven't already.
  3. Is it summer or winter where you are, what is the ambient temperature? Is the radiator an intake or exhaust on the case, and do the graphics card(s) exhaust their heat out the back of the case or into the case? I have had a large number of AIO coolers fail over the years. Even if the pump is running it is not a guarantee that the water is flowing properly, or that the cooler is able to efficiently conduct the heat. How quickly does the air exhausting from the radiator take to heat up after the stress test starts? If the air exhausting from the radiator is cold, then the cooler will either need to be remounted, or replaced. If the air exhausting from the radiator is taking a long time to get warm then the cooler might need to be replaced. The most common issue I have seen with AIO coolers is oxidation of the heat blocks creating an insulating layer between the CPU and the water. This can result in increased idle and peak thermals. Oxidation on the heat block and radiator can be dislodged by the moving water and accumulate at restrictions in the loop and eventually block the water flow. This can further reduce the efficiency of the cooler. A less common problem that I have seen in a couple of AIO coolers is water evaporation. While the AIO coolers are sealed loops, the water can slowly pass through the rubber tubing, this evaporation process is accelerated if CPU temperatures are kept above 60°C for extended periods of time. Generally this should not be an issue until about 3-5 years though.

    Case Fans: Lying About Performance?

    Yes. There isn't the best standardisation on how measurements are taken, or whether or not the measurements are even performed with calibrated test tools, and there is no accreditation authority for this. A range of dBA and CFM is typically used on PWM fans, where they are designed to have the fan speed controlled. In my experience the Corsair fans that I have used have all been around 10-20dB louder than the manufacturer claim (possibly they had tested at 10m rather than 1m).
  5. Under sources, click the little plus symbol and add what you want to capture (display capture, game capture etc).

    Did I lose the silicon lottery?

    It really depends on your workload, in all of the applications I run on my R7 1700, RAM has made no difference. I get the same performance with the RAM at stock JEDEC 2133CL15, or overclocked to 3333CL14. However, if there is a lot of cross core communication with the workload, for example a physic engine computation in an un-optimised game, then the infinity fabric can cause bottlenecks which the RAM clock increase can alleviate. I would just stick with 3.8GHz. If your cooler can handle it and you are comfortable then you could increase you cpu voltage to push it a little further, although with Ryzen once you hit the wall you typically need a significant power increase for an insignificant performance boost.
  7. Unlikely. On the Wraith Spire my R7 1700 I was only able to maintain reasonable temperatures up to about 1.38V.
  8. Set cinebench priority to run as realtime. Run it 3 times with each configuration and take the average.

    AMD Ryzen vs. Intel - Programs

    I use a lot of programs that heavily utilise AVX2 instructions, which Ryzen requires 2 cycles to complete and thus have relatively halved performance. Although, I am not aware of any specific programs that run on Intel and not on AMD, software would have to be pretty poorly coded to not work on AMD hardware. Is there an alternative software package for the task?

    Is watercooling dangerous?

    The chance of there being an issue is very small, although it is best to always have a plan in case something goes wrong. Personally, if my water cooling loop leaked and killed everything in the system it would be pretty sad, although I have several spare computers to use in the downtime and have contingency budget set aside to replace it all. Consider replacing the thermal paste, and/or try undervolting it.

    Ryzen 1700x overclock

    That sounds pretty average for the R7 1700X.

    Ryzen and RAM CAS Latency

    I personally use a 3200CL14 kit running at 3333CL14. In my workloads it made zero difference compared to 2133CL15, but in several games (not all) you will notice a small improvement, I personally wouldn't consider the benefit worth the cost. Depending on your luck with silicon lottery though, you may not even get the rated speed out of the RAM due to the IMC on the CPU or poor RAM overclocking still present on some motherboards.

    OC with ryzen 1700

    Are you putting the system under load when you are checking the clock speed? Make sure the windows power profile is set to high performance. Try increasing vcore to 1.3-1.35V. How many weeks does a system need to be running at under full load to call it stable? The only crashes I get on my Ryzen system are have been traced to driver failures related to the killer network card on the motherboard, and it is typically 3-4 weeks between crashes.
