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!
