CPU temps while stress testing
CPU temps while stress testing
Overclocked i7 8700k at 5ghz with 1.29 v, cooling it with a Corsair h100i v2. Temperatures are stable but during stress tests I observed fluctuations of about 16 degrees from 78°C to 62°C every few seconds. I expected them to stabilize around the max temperature, only changing slightly. Was my assumption correct and is this typical?
Ravensius shared their experience with an overclocked i7 8700k running at 5ghz and 1.29 v, cooled by a Corsair h100i v2. They observed temperature changes during stress tests, noting fluctuations of up to 16 degrees between 78°C and 62°C every few seconds. They questioned whether this behavior was normal and referenced a graph showing stable temperatures after about 10-15 minutes on a liquid cooler.
I have overclocked an i7 8700k to 5ghz at 1.29 v with a Corsair h100i v2 cooling solution. The temperatures are within acceptable ranges, but during stress testing I observed fluctuations of about 16 degrees from 78°C to 62°C every few seconds. Initially, I expected the temps to stabilize around the maximum and stay close, only varying slightly. Was my assumption correct? Is this behavior typical?
Here is the graph from the 15-minute stress test:

Colors indicate CPU usage, temperatures, and core frequency.
It appears the fluctuation is likely due to the test itself rather than cooling performance. After about 10-15 minutes on a liquid cooler, I recommend running Aida 64’s stability test and analyzing CPU FPU, cache, and other metrics.

overclocked i7 8700k at 5ghz with 1.29 v, cooling it via a Corsair h100i v2. temperatures stayed stable but during stress tests I observed fluctuations of about 16 degrees from 78 C to 62 C every few seconds. i thought it should stabilize around the max temp. is this normal?

colors indicate usage, temps in green, core frequency in orange.
the test appears to be just a stress run and not accurate readings. after about 10-15 minutes on a liquid cooler, i recommend running Aida64 stability tests and checking CPU FPU/cache performance.
something seems off and i need more details.
Ravensius shared their experience with an overclocked i7 8700k running at 5ghz and 1.29 v using a Corsair h100i v2 cooler. They reported stable temperatures overall but noticed significant fluctuations during stress tests, jumping by 16 degrees from 78°C to 62°C every few seconds. They questioned whether this behavior was normal or if they were mistaken about the expected temperature plateau. They attached a graph showing CPU usage over time and mentioned issues with Aida64 failing after short testing. They asked for more detailed specifications and confirmation on GPU, motherboard, and PSU compatibility.

Overclocked i7 8700k, 5ghz at 1.29 v, with a Corsair h100i v2 for cooling. Temperatures are stable but I observed fluctuations of about 16 degrees during stress tests—from 78°C to 62°C every few seconds. I expected them to stabilize around the maximum and stay close. Was my assumption correct? Is this typical?

It looks like the test itself is causing instability rather than just a normal variation. I should run Aida 64’s stability and stress tests, checking FPU and cache performance.
Aida64 stopped after a few seconds with a warning about hardware failure. Something seems seriously wrong—I need more details.

They questioned whether this behavior was normal or if they were mistaken about the expected temperature plateau.
They attached a graph showing CPU usage over 15 minutes of stress testing and noted the orange line represents core frequency. They suggested using Aida64 stability testing to analyze CPU performance under load, including FPU and cache stress, to get clearer insights.
Ravensius also mentioned hardware concerns: full specs for the GPU, motherboard, power supply unit, and all drives (including hard drives, SSDs, optical drives, and possibly a floppy drive).

Ravensius shared their experience with an overclocked i7 8700k running at 5ghz and 1.29 v using a Corsair h100i v2 cooler. They reported stable temperatures overall, but observed significant fluctuations during stress tests, jumping by as much as 16 degrees from 78°C to 62°C every few seconds. They questioned whether this behavior was normal or if they were mistaken about the expected temperature plateau.
They attached a graph showing CPU usage over 15 minutes of stress testing and noted that the readings appeared inconsistent. They suggested downloading Aida 64 for stability testing and advised running stress tests on the CPU, FPU, and cache.
Ravensius also mentioned hardware concerns: full specs were requested, including GPU, motherboard, power supply unit, and all drives (HDD, SSD, optical drive). They clarified that they were referring to physical components rather than storage media.
