Normally the heat sink fan would run at full speed when I start the pc but only for few seconds and the sound is really audible at full speed then it would slow down and is silent from there on.
But now, when in use, even if I am just browsing or even when the pc is idle the fan randomly runs at full speed for few seconds then it goes silent, this keeps happening every 5/10 minutes and it's really annoying.
I used Open Hardware Monitor program to check the temperature and it shows the CPU's max temp is 50C and when in use the temp fluctuates around 36C - 42C, this I think is an acceptable temperature for the CPU.
I assembled this pc myself in 2012 and this is the configuration:
- Cooler Master CM690-II Advanced Mid Tower Cabinet
- Gigabyte GA-H77-DS3H Motherboard
- Intel 2.6 GHz LGA 1155 Dual Core G620 Processor
I would really appreciate if someone could help me troubleshoot this issue.
