my (stock)cooler goes from 1200-2900 rounds per minute.
When I really stress it, the TJ temperatures hit 70°C.
Checking out the CPU fan rpm in HW Monitor, I see the fan control reacting very presizely to my TJ temperatures.
(Putting aside how real or not real the temps are), the fancontrol always puts the maximum temperature of my two highest cores to 70°. Whenever I see it going to 71°C the fan increases by 50-100rpm, until it is 70°C again, then lowering the rpm slightly.
So basically I ran this Rendering test,
after 5 min
rpm 2300
tj. 70, 70, 69, 65
after 10 min
rpm 2400
tj. 70, 70, 59, 65
Later the fan stabilizes at 2500rpm to not exceed 70°C here. The maximum fan speed is 2900 rounds per min!!
It clearly indicates that my fancontrol thinks this is a safe value at maximum load and it pushes up the rpm to not exceed the temperature, but keeps it at that temperature to keep my fan as quiet as possible.
I am running at open case in these hot days, and my CPU fan needs to fresh air. When closed case my case runs at full speed 2900rpm at about 72,71, 69, 67 so just barely keeping them at 70. It is not coming enough fresh air in my case.
I can not tell the fan to accelerate further to sustain certain temperatures. It is that way either with Gigabyte's Smartfan activated or deactivated. I can not change this other than manually putting my fan to 100% but who does that?
I find it quite interesting because my system could regulate the temperatures a lot lower and my fan running a lot faster. But the board thinks that these temps should be sustained.
if i could i would set all of my fans at 100% all the time the noise doesnt really bother me at all... and hey the cooler it is the better right
Well, it depends on how you use your rig and what you use it for. If you use your rig for gaming with closed cans (headphones) than, no, noise may not be an issue for you. If you however use your rig for general use, gaming, and to store your 70GB of ripped CDs and purchased music as your audio centerpiece, well then, noise is going to be a consideration and you may not want all your fans spinning @ 2000rpm

It's not just about how fast the rig is, its about how good the rig sounds.
