100C might be concerning, depends on your case airflow and ambient temperature. The bigger issue is the crashing. Modern CPU's should throttle when they get hot, not crash. I would recommend running OCCT in CPU mode with the instruction set on SSE and AVX for an hour each. Repeat with the Memory mode, it also has an SSE and AVX option. Then do 3D Standard for an hour and VRAM for an hour. This should help you find which component is causing instability. PS, 218 watts under load is fairly high for a 13600K. Either your chip is overclocked or you are running an old BIOS version which uses too much voltage. This is known to damage 13th/14th gen chips. Answer from DZCreeper on reddit.com

r/overclocking on Reddit: CPU temp maxing out 2 seconds into OCCT Power Test

  • CPU: i7-6700k

  • GPU: Zotac gtx 1070

  • RAM: 16 GB (8x2) HyperX Savage 2666Mhz

  • Mobo: Gigabyte Z170x-Gaming 3

  • PSU: 650W Corsair CS Series

Hi, so I have a stable (I believe) OC of 4.5Ghz, I have tried the standard OCCT test with no failures, and have been messing around with the overclock for a week to make it as stable and efficient as I can, no problems during gaming at all, no usage or temp issue, voltage working as calculated.

I thought I would do the OCCT Power Test and the first time within seconds 33,000+ errors were detected at once followed by BSOD . The screenshot below is what I managed to take the second time without BSOD.

Any thoughts on why the test maxes out the CPU temp? I would say false reading but BSOD tells me otherwise.

Any help is appreciated, cheers.

Hi I'm getting 84 CPU (Ryzen 5 1600x 4.1 Ghz) and 78 GPU (RTX 2060 +135 on core, +1000 mem) on Power test in OCCT. Are this temps okay for this stress test ? I am getting below 70 while gaming no matter which game. Should I change my termal paste and pads on GPU ? ( My setup is 3 years old and didn't change them once )

r/OCCT on Reddit: Questions about temps in OCCT small/extreme
December 13, 2023 -

I just recently upgraded my CPU to a 5800X3D. My cooler setup is a pretty standard fan setup and a 240 Cooler Master AIO. I've been having normal temps so far (Idle around 50°, Gaming up until 70°) and I decided to do some stability testing to make sure everything's fine.

OCCT Large/Extreme completed with no errors and a maximum temperature of 69° after 1h. As soon as I start a test on the small dataset with the the same settings, I cross the 90° thermal limit I put in my settings, apparently up to 93°.

Is this to be expected? I know the thermal limit for the 5800X3D is supposed to be around 90°, but these temps seem a bit too crazy for my taste. Any anecdotal evidence or help you guys might have?

Describe your problem. List any error messages and symptoms. Be descriptive.

I was playing Deadlock on the recent patch and at some point, after about 5 minutes in game, my PC crashed to a blank screen. I still had sound, but my fan (I believe GPU fan) was on full blast and I had to manually restart the PC. After restarting, my second monitor would not be recognized. I fixed this by disabling and re-enabling my graphics driver in windows settings. Now I'm running some tests to find out what happened, and while running OCCT I noticed some high temps under the load from the test. I have screenshot here of the test while it was running. I ran it for a little over 15 minutes with no crashing or issues. What could be causing the crashes? And are these temps cause for concern?

List anything you've done in attempt to diagnose or fix the problem.

i9 10900k with nzxt x63 kraken. It's was prebuilt creator pc from nzxt. I only enabled xmp. Long story short I downloaded occt to try and figure out an error that's restarting my pc. When I run cpu test on occt my temp is only around 60 but like I said in title when I run the power test it gets almost to 100 and I just shut it off. Don't know much about this but this can't be right?

May 12, 2025 -

Newbie here in this area, just want to check out if the 7800x3d built with a Thermalright Peerless Assassin 120 SE ran "ok".

No OC'ing (AFAIK) is done on the CPU.

Idle temps are around 46-52 C, depending if I'm using the MSI center "quiet" fan profile or the stock (UEFI) one respectively.

I've ran the OCCT CPU test for some hour and noticed that it does not go above a thermal of 89 degrees C. I suppose this is some thernal safety in the CPU?

Meanwhile the power (wattage) seems to be 75-78W. Are these numbers to be expected? If not, should I check something else?

RAM is 2 CL36 sticks of GSkill trident Z Neo5 RGB at a speed of 6000.

r/buildapc on Reddit: 100C CPU temp in stress tests, should I be concerned?
January 26, 2024 -

I've had my PC for a little over a year (current build list) and performance has been pretty good, hasn't blown me away and I haven't done any OCing (in fact undervolted at one point), but it's been alright. A couple of weeks ago I decided to add a second fan to my CPU cooler (NZXT T120) just to help with cooling a bit and also reapply thermal paste. Shortly after I played the game The Finals for the first time and at some point I noticed it was COOKING my CPU (core temp reaching 100C) and at some point, my PC just shut off because I guess it got too hot. Other games I've played since then haven't given me issues (max temp I've seen is 85C) but they haven't been too intensive of games (ex: Farm Sim, TF2, and Golf It). Also, idle temps are completely normal, around 45C. I decided to run a stress test on OCCT to see if it was just a problem with The Finals or a larger issue. My knowledge of PCs is fairly surface-level, I know how to build them and that's about it, so I'm not sure how to interpret the results. I ran a 5-minute test and the whole time temps were about 100C, power draw was around 180W, P-core clock speed of around 5000Mhz, and E-core clock of around 3900Mhz. Once the test was finished temps immediately went down to around 55C. Are these results indicative of a problem? And if so, should I reapply thermal paste or try a new cooler? One thing I'm a little confused about is why the P-core clock speed showing 5000Mhz while my CPU has a base clock of 3500Mhz, does that mean it's OCed or am I just fundamentally misunderstanding what these speeds mean? Here are some pics of my PC in case it helps to see my flow (pretty sure my case flow is pretty standard):

r/OCCT on Reddit: Why does the CPU temp go from 40 to 80 celsius in 2-3 seconds?
March 3, 2025 -

I have been running some stress tests and benchmarks in 3DMarks and there my cpu temp slowly climbs as the test goes on. And I have only ever got it to peak out at about 70 celcius even with their most performance heavy stress test for 20 minutes. However when I tested the CPU test in OCCT the temperature goes from about 40 celcius to about 80 in 2-3 seconds as soon as I start the test? How come and should it do this?

r/OCCT on Reddit: What exactly is the power test?
March 8, 2023 -

Hey everyone,

I have been using OCCT to check my temps under high stress. I recently got a new case with more fans, and also got a new CPU cooler (both the case and CPU cooler are from Be Quiet). While doing a stress test my CPU temps don't exceed 73 degrees celcius, but they mostly max on 71 degrees. Might be nice to tell that it's the I7-8700K with a Be Quiet Pure Rock 2.

I found an option to test my RAM, which I tried out. Then I found one for VRAM, which I also tried out. Both just for 1 minute, nothing special. Then I noticed a test for 'power', which I figured might test how much watt my pc was using or could be using. While also doing this test for a minute, I noticed my temps going all the way up to 97 degrees celcius at its max. This did worry me a bit, as my temps don't even get close to that while my PC is running intensive games or whatever.

As it might be relevant, my PSU is a CorsairVS650, which for my I7-8700K and GTX 1060 6GB would definitely be enough, never had any issues in a few years time. I would just like to know if this test should make me act, or if there's some logical reason why only this test manages to get my PC this hot.

Hi all folks, I am very new to OC, recently OC´ed my 17000k to 5.1ghz, I can run CPUZ stress test, Prime95, OCCT CPU test, and OCCT Linpack for long time with no problem, max temp 75. But when I try the PSU test, my cpu temp goes straigh to 90, and one degree more every second until reach 100 and crash.

Its this expected?

Hello, i've got some issue with my first new built pc, bought all the parts myself, and mounted them too, so my issue is as the title says, just changed the thermal paste of my cpu about 10minute before running a stability test on OCCT and the cpu temp explode, goes from 40 to a 100 in a second, i'm not finding any solution to this problem, this morning i got a blue screen saying "DTC_watchdog_violation" please help.

The specs :

Motherboard : Msi pro z790-p Wifi ddr5

CPU: i5 13600KF

GPU : Zotac rtx 3070 ti

Ram : DDR5 corsair vengeance 2x16

AOI : Cooler master liquid v2

SSD: WD black sn850x

Power : MSI A750GF 80goldplus

I don't know if it has to do with the Power Supply, but i really dont know what the issue with the pc, and if there is one or multiple issue, also i never figured out how to control the argb light on the pc it always turn red idk if it default color or a signal to an other issue.

PS : for the blue screen i had saying "DTC_watchdog_violation" i don't know if the new sound blasterx g6 i just bought could or may have cause the problem to occur but hey if anyone know i take it !

Thanks for your response

r/OCCT on Reddit: OCCT Power Test
January 18, 2021 -

Hello,

I've been having issues with my PC resetting while playing some games (Spellbreak, Rust) or streaming (HBOmax, Netflix). It does not crash during League of Legends or while watching YouTube). Some people have suggested a power supply issue (though I have a 700 w PSU). I ran the power test on OCCT. I'm not sure what it did but from looking at the temps/power/etc. it seems like it puts a lot more stress on the hardware than those games would. After the hour test, my computer never crashed and the test found no errors.

Would this rule out a power supply issue and probably an overheating issue?

I agree with the other posters! ^ It's very possible it's a cooler issue. Although your cooler is rated for 150w, your CPU has a TDP of 125w (at base clocks), it draws much more than 150w at boost speeds, and whilst stressing. In fact it can draw up to 251w (PL2). It's very possible the cooler just isn't adequate enough at high clocks/load. Which Noctua paste are you using? H1/H2 have optimum operating temps between 70-120c, so that paste is good enough. As @hotaru.hino and @dorsai suggested, check cooler is seated correctly. You will obviously have to re-paste. Noctua's instructions suggest best method is to put a pea sized blob in centre of CPU. 2-3mm in diameter. Then seat the cooler. If the cooler has 4 screws, then tighten them in a criss-cross pattern from one corner to the opposite diagonal. This will ensure as you tighten down, you get an even spread of paste.

Yeah I have an old GPU I can try if needs be. I'll see what happens when I remove the RTX from the system entirely and go from there. Haha to be honest, I decided to build this PC not because I needed anything in particular but because I fancied a bit of a project so now I have the means to fiddle with things I may well get obsessed with thermal paste soon too! Yeah, I will definitely get you posted! Thank you so much for your help so far, I've really appreciated having someone to throw ideas at me! No worries, glad to offer help. That's the best thing about TH forum. Everyone bouncing ideas around, learning lot of good stuff as we go along! Love it!
