Is it ok if CPU temp jumps around?

cpucpu-coolerfantemperaturewater-cooling

I had a Coolermaster Hyper 212 EVO and my CPU temp was around 36-45 idle so I bought a Corsair Hydro 105 because someone suggested it to me, and my temps have gone to 29-50.
My question is, is it normal for the temp to jump around so much when the computer is just idle? By idle I mean I don't have anything open, or just one browser. If it's jumping up and down ten-fifteen degrees does that mean I installed the fan wrong?

Best Answer

If the temperature is as low as 29c, it sounds like it was installed properly and is capable of cooling your CPU.

The higher than normal temp of 50c could be an indication that your radiator fans are not turning on quick enough. Is there a way to configure your radiator fans to turn on at a lower temp?

I would also see the results of testing with a high load on your CPU using a program like prime95. https://www.mersenne.org/download/
