Those are the CPU coretemps just for reference when I was trying to provoke the fan in hybrid mode. Can you explain the functionality/feature that is requiring me to hold down the power button for X amount of seconds before it can come back on after one of its shutdowns? Is that a PSU thing or the motherboard? Through all this behaviour do you suspect the PSU may have an issue? I'd rather it be that than go the motherboard / CPU route, laugh. Thanks for your insights.

Yes, I have indeed seen the fan spinning when it was in normal mode and the system was on. Currently I am in hybrid mode and it is not spinning (I was able to boot the machine successfully this morning and am writing this on it, but not stressing the system.) I'll kick off a compile and see if the fan spins up when it hits 500W. [update:] The compile has been going for 10 minutes, the CPU is pegged at 100% on all cores, I am at 4.2Ghz however instead of 4.5 (backed it down to stock to troubleshoot). Temps are at 55 roughly. The fan has *not* spun up on the PSU in hybrid mode interestingly. Now that I think back on it, I may never have seen the shutdown behaviour in hybrid mode, does that make any sense that it would happen in normal mode with the fan on all the time? [update2:] Compile completed but I got the full shutdown playing a game. This was in hybrid mode. However, in hybrid mode I can now bring the system back up by holding down the power button for 30 seconds and then powering up again. Ugh.

This PSU has a hybrid/normal switch on it where if it's on normal it's spinning all the time, if it's on hybrid it only spins up if you get to 500W draw or so. When the problem was occurring I had it on 'normal' which would have the fan spinning all the time. I'm currently on hybrid mode to see if that impacts the shutdown issue frequency. Do the AX860 era PSUs have a thermal shut down failsafe? I've seen other devices, like cable set top boxes that if they thermally shut down you can't restart them unless you physically disconnect the power cord just like I'm experiencing w/ the AX860. Maybe they have something like that in the AX860. Thanks -

Hello, I'm trying to troubleshoot some unpleasant behaviour on my four year old build (2016) I put together with the idea of longevity and stability at the time. i7-6700K oc 4.5Ghz (also happens at stock) 32GB Corsair DDR3*00 Asus z170 Sabertooth TUF moboCorsair AX860 850W modular power supply MSI NVIDIA RX2060 Video card Corsair i115 RGB AIO Cooler (20 degrees idle, 70 under load w/ all cores at 4.5Ghz) Samsung 970 m.2 NVMe SSD 2TBWindows 10 Pro x64 1909 Lately the system has been periodically (once every few days) shutting completely down (no hints in event viewer), both under load (compiling) and sometimes during a 3D card use transition. The odd thing is that when it shuts down like this, I cannot immediately bring it back up with the power button. Previously I was able to get back to functioning by holding the power button down for 15-30 seconds, releasing and powering up again. That doesn't seem to be working any more. Now I am having to pull the power cord from the PS and wait for an hour or so, plug it back in and fire up. Thankfully it works when I do this, I'm not sure what the exact rest time it needs is though. I haven't seen this sort of thing before, esp. the having to wait to get back on line (almost like some devices' thermal warning shutdowns). I've replaced the video card, the AIO Corsair 115i, re-installed Win10 x64 Pro and re-seated everything. I'm thinking initially it's the PS and am ready to RMA with Corsair as it's in warranty but wanted to see if anyone has seen this behaviour before. Thanks! Edit: The red/orange power LED is on on the motherboard during this time, there is also flickering light on the ethernet connection during the time I can't power up fully.

If you opt not to install the iCUE software, what speed do the pump and fans default to? Is it 'balanced' or 'quiet'? Do the pumps and fans crank up automatically without software control or do they run at a set speed? And are there other another other bench/testing/OC apps that can monitor their speed? Thanks -

Just to follow up and close this loop, I installed the new H115i RGB XT a few days ago and got the USB Link cord with it, now a micro USB connector btw. Temps dropped 30 degrees under load, and I'm able to set the pump and fans to extreme, balanced or quiet. Corsair also ok'ed the RMA for the non-functioning one. Thanks for the help in this thread.

My cores look to idle in the mid to high 20s when the CPU steps down to 800Mhz. On a cold boot and then just browsing around after start up I'm in the high 30s and then drop down when I'm not doing anything. They don't stay pegged up there. This is with core temp 1.15.1 monitoring. But you're right, hopefully the new AIO will go smooth. One other thing I thought this morning was maybe I accidentally used the wrong standoffs for the mounting and the plate isn't on as firm as it should be? Seems a stretch, since I do get these very low idle temps. So at least it appears to be doing what it's supposed to when farting around around, just not under load. Thanks for the help. [update] Corsair tech support just got back to me and suggested the pump/impeller might have gone south and wants to replace if its in warranty. I think their AIOs are 5 years, so I should be ok at 3/2016 purchase.

I should have listened to the review, that Amazon cable is a micro usb to 5 pin mobo header instead of what I needed for that model, a mini usb to 10 pin mobo cable. Ah well. Have the H115i RGB Pro XT arriving tomorrow.

Thanks for the note. I did just re-apply some Corsair paste last week and it didn't make a difference. Unfortunately. I'll try this cord from Amazon and see if its wired properly for iCUE, though one of the reviews seemed negative about it. https://www.amazon.com/gp/product/B072Q1MBSG/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 The voltages are stock, and I'm just using the Asus' performance preset which OCs it 12% to 4.5Ghz. You're correct that this hasn't been a big concern before (including compiling MAME twice daily), but recently I'd started to get complete/immediate system shut downs which I have been trying to troubleshoot since I got a new GPU around the same time.. and then I saw these wacky temps. I may end up with the newer CORSAIR iCUE H115i RGB PRO XT, 280mm Radiator, Dual 140mm PWM Fans, Software Control, Liquid CPU Cooler, CW-9060044-WW. How long should the AIOs last, am I hitting an age limit w/ this one from 2016? Thanks -

Corsair Hydro Series H115i Extreme Performance Liquid CPU Cooler Cooling CW-9060027-WW Hi, I've had this cooler on my oc'ed i7-6700K at 4.5Ghz since 2016 but only recently had occasion to stress test the system with OCTT 5.3 (troubleshooting AMD Radeon 5600XT issues). I was shocked to see my thermals jump to 100 degrees under load, (coretemp used to monitor). I never got a Corsair USB Link cable in the original package that I can recall so it's never been hooked up so I can't alter the pump speed. The Asus mobo (Sabertooth Z170 Mark 1) w_pump header connected to the AIO is saying the pump RPM is always around 1500rpm and never goes up, which probably explains the super heated readings under load. Is my H115i 'stuck' in quiet mode since it's never been connected via the USB Link cable to iCUE? Is this an issue with this generation of AIOs? Where can I get the USB Link cable? Thanks!
