I'm trying to use SpeedFan to get some control over my radioator fans, as that was what Gigabyte recommended for my motherboard.
Anyways, I'm fiddling around, finding the correct fans and so on. Then I'm firing up Prime95 to test my fan curve. Once the test started, the fans went crazy, looking at HWiNFO, the CPU temps instantly goes up to 80 degrees. SpeedFan also reports these temps. It stays at around 80 and wont go down, until I stop the test and the temps instatntly plumits back down to 34.
Here is an image of the temps, when starting and stopping the stress test:
CPU: i7 4790k
MB: Gigabyte Z97X-Gaming 3
