Summary0000933: SF detects spikes in GPU temperature
DescriptionSometimes while playing a flash movie (and only those) in full screen, SF detects "GPU Temperature" spikes, such as a jump from 50 deg C to 150 deg, and back in the the next sample. These spikes can not show actual temperature changes, changes of this magnitude take much longer (minutes, not seconds). The annoying thing is that temperatures like this trigger some SF alarm events that I defined (at around 90 deg, temps during gaming go up to 85 degs). The alarms drop the video out of full screen. Has anyone seen this, too?
Steps To ReproduceWatch a video on YouTube in full screen.
Additional InformationSee the screenshot. Sometimes the ambient temp shows a corresponding downward spike.

I am having problems with spikes, too. Fans speed up randomly, pretty annoying.

I have V4.33 and am using to monitor an ASUS P5B with E4300 OC to 300MH FSB (2.7GH). I am getting spikes in the CPU temp (starts at 47, spikes to 64, once to 80!). These appear to happen in one read cycle per the graph, but remain at the high. All core temps are normal (usually 40 and 35). Running SETI to drive CPUs to 100% with the stock hsf. Today I got very weird temp readings on the System (Mainboard?) of -1C with SpeedFan, +191C!! with ASUS Probe, and -65C with PC Wizard 2007. The CPU temps are consistent across all the monitoring software.

It sure looks like funny results from the Winbond W83627DHG monitoring on the board. When the CPU was at 80, I wasn't able to burn my fingers on any heat sinks on the board.

The AUX has always been at about 115C, but is probably not connected on the board.

I am getting spikes like this too.

Before Speedfan jumps the fans to 100%, could it check for 2 samples on huge deltas like >20% per sample.

That would quickly "hide" these spikes from ramping the fans to full blast.

For the record, since at least one year, I have no longer observed this.
Since then, these have changed: CPU, GPU, Speedfan, Flash player.
