The setup : non oc i7 3770k with boxed cooler on gigabyte z77-D3H motherboard with F18 bios.
So the summer came with full power and my room temperature rose to 30 -31°C , so as expected the CPU t° with it. I realized that i haven't heard my CPU fan recently so i checked the temperatures under load and they were ~80°C. Back in the day i could clearly hear my stock fan when the CPU was under heavy load and now i only hear it when i start the my PC and fan goes nuts.
Using EasyTune6 from gigabyte i can see that the rpm never go above 2100 even though i clearly remember them to be around 3300 when i was messing around with oc 4 months ago. Tried disabling fan control in bios - the fan stays @2100-2200 rpm. Tried using the EasyTune6 smart fan control - i can reduce the rpm and stuff as usual , just for some reason the max is never above 2100 rpm and this is too low for the current heat in my room. Tried changing the fan control method from auto to voltage - this wasn't really working since i couldn't control it with ET6 so i swapped to PWM mode. I guess that is the mode it goes to by <auto> since i have the same results as when on <auto> - controllable but not above 2100rpm.
I can clearly hear that the fan can go faster than 2100, even saw it go over 3000rmp randomly when i was messing with the "voltage" fan control , even though i didn't really had control over that.
So yea , awaiting suggestions.

Simple solution : get an aftermarket cooler and overclock your 3770k .:p

Just get into bios and restore defaults and after that dissable fan control
This will solve your problem

I will try that and report back , but i don't see how changing memory times (as that's the only thing ever changed in the bios) will fix the problem. All the default settings for fan obviously didn't do anything since that was the reason to start looking into them as the fan wasn't rotating fast enough.

Loaded optimized defaults , disabled fan control -> nothing changed. After the initial spinoff the fan goes back to 2051-2045 rpm. Even if i don't let windows load and go back to back in bios and check the speeds there , its still the same result ;(
