I just found out that you can easily tune your fan speed by using (an up-to-date) motherboard utility like Asus AI Suite 3 to make your pc quieter. Unfortunately, I can't install it probably because my motherboard is too old to be supported:
At least Asus AI Suite II works:
Unfortunately, I does not seem to be possible to tune fan speed with Asus AI Suit II :( Is there another way to do so for my (old) motherboard?
Edit
I tried SpeedFan, however, it shows me that my CPU temp is too hot, even though I am sure the important temperature that matters is the CPU core temperature, which is alright. When I turn "Automatic fan speed" on, nothing happens, probably because of Temp1 (CPU Temp)?
