  1. I attached a screenshot of a Prime95 SmallFFTs 15 minute load using the quiet settings. With the fans barely spinning my coolant temp slowly rose up to 28C. The air coming out the AIO was slightly warmer this time. The CPU temps also went up by 3-5C up to 83-85C. The CPU automatically adjusted his all-core clock to ~3.95ghz compared to ~4.125ghz when the fans and pump are running at full speed. I'm guessing that's just the nature of these new zen2 chips. While the TDP isn't that high (65W) the Tctl/Tdie temperature can still get quite hot since all that heat is coming off that single little chiplet. I don't think I'll ever be able to use iCue to setup a fan curve based on coolant temp since I only get a 1C delta (~24.5C @ idle and ~25.6C @ load) in my coolant temps when the pump is set to "balanced".
  2. I'm only using HWinfo64 for the CPU and Precision X1 for my GPU. I disabled the reporting of the AIO's status in HWinfo as per Corsair's support article. The air exhausting from the back of the rad doesn't feel warm at all. The CPU will hit 80C in prime95 and CinebenchR20 while some other benchmarks (ie: wprime) seem to be less intensive and usually over around 50-60C. I've looked at reviews that benchmarked the 3700x temperatures and the results are all over the place since they're not all using the same benchmarks. Some sites are using the stock cooler while others use an AIO or a custom loop. Quite honestly my temps *might* be OK but it still doesn't explain while my coolant temp isn't fluctuating. I can't even use the default fan curve in iCue since it's based on coolant temp.
  3. I reran the tests just to grab screenshots but I can assure you that I'm getting pretty identical results over 30+mins of SmallFFTs. The test in my screenshots was 6 minutes not 6 seconds btw. If I lower my fans to more acceptable levels sound wise (around 50% / 1100rpm) I get identical results in regards to CPU and coolant temperatures. I've never seen my coolant go over 25.6C. I don't think that's a realistic value given the fact that it's trying to cool a 65W load at 24C ambient.
  4. Hey guys, I'm making a post on the forums since Corsair seems to be having issues replying to support tickets swiftly. Like many of you, I built a new rig last month with the release of zen2. The full specs are in my profile. I paired the CPU with a H115i Platinum. My current setup has the 280mm rad setup as a front intake with 4x ML-140s in a push-pull config. I've got 2 additional ML140s setup as bottom intake fans and two other 140mm fans that came with my case as top exhaust. I've also got two 120mm 1850rpm Gentle Typhoon fans in push-pull with my GPU radiator setup as a rear exhaust. So overall I'm assuming I've got more than decent airflow. Here's my issue. While the temps I'm seeing seem OK at best (80C under a full Prime95 small FFTs test with all fans running at 100%) the reported coolant temps in Corsair iCue is wrong. At idle my coolant temps is around 24.5 - 25C while under load it doesn't even go up by a full degree. My ambient temperature is at 24C. I'm pretty sure that my idle coolant temp should at least be a couple degree above ambiant. Under load I'd expect and additional 6-10C rise in coolant temp. Please see the attached screenshots. I placed my hand on the tubing while the benchmark was running and it doesn't feel warm at all and I don't feel any or much flow. iCue seems to be reporting my pump speed correctly at 2800rpm. I tried re-seating the block three times and I also used different thermal paste just to be sure. I'm getting near identical results each time. Anyone ran into a similar issue? Anyone thinks I might have a defective unit? Thanks!
