Thermal Throttling issues

peyton_a · January 8, 2019

Ok so in my pc is a I7 8700k overclocked to 5ghz with a evga gtx 1080 overclocked to 2050mhz with 16gb of corsair vengeance rgb ram and a sea sonic 620w power supply in the lian li o11 air rgb case. It currently has 10 fans (not counting the CPU cooler) and 5 are intake 5 exhaust. With the first weeks of the build being complete the CPU was running cool at 52c to 58c playing games like rocket league battlefield 1 battlefield 5 etc. I recently decided to see what my fps was in battlefield because for some reason the pc was dropping performing terribly in battlefield 5 and couldn't keep up with ultra settings, I opened cam to see what was going on and see what fps it was at to be surprised to see my CPU at 85 to 80c which surprised me because it never had cooling problems in the first 2 weeks of the build and the fans weren't all the way turned up but my fan curve in bios for all my fans is suppose to make them go 100 percent past 62c. So I rebooted checked the bios and the fan curve was the same thing it was suppose to be so I tested it again with the panels off and it was still running hot on the games it had performed fine on so I thought at first the cpu cooler maybe didn't have good contact with the CPU but I pressed the CPU cooler into it while the game was booted in game and found no difference, would appreciate it if someone could help. UPDATE: today I re launched battlefield 5 and the cpu percentage is way lower yesterday it was constantly at 90 percent to 100 percent when gaming right now the highest ive seen it spike is 70 percent but its averaging about 62 percent now and running 10c to 16c cooler. but its very confusing because I have the same programs open: battlefield 5, cam, origin, Nvidia settings, Spotify, ICUE, and discord

1.) stop messing with components while its on - your going to fry something (the odds are much much higher)

2.) replace the Thermal Paste

3.) Screw on AIO Monkey tight, not gorilla tight.

or

Drop the overclock and check temps.

EDIT - I said AIO, however you never mentioned what type of cooler

He probably has an AIO, The PC-O11 Dynamic/Air has a 155mm CPU Cooler height limit. There aren't much air coolers that fit in that height limit and performs well enough for an 8700k at 5GHz, considering he didn't have any thermal issues at the start.

it is a cryorig h7 quad lumi also I launched the game today and the one thing that ive noticed is way different is the cpu use percent yesterday it was at 90 percent to 100 percent full throttle during gaming now the highest ive seen it spike too is 70 percent and its running about 10-16c cooler

Sounds like you hit thermal equilibrium with your 160w TDP dissipation and the OC. Add a second fan to your cooler if you can. Im surprised that thing didn't tank at first OC. You were likely close to the thermal threshold all along and finally hit it, likely from your PC now being less efficient with airflow due to dust, etc since building it and tipped the scales. That would be my guess.

Add that second fan at a minimum to that cooler imho.

What are your temps during idle and regular gaming? HWMonitor is great as it keeps the min max threshold until you close it.
