Case fan speeds?

[swek]

Using an ASUS motherboard here, with 2 AF120 LED as front intakes. How shld i configure my fan speeds for as silent as possible without damaging or thermal throttling my pc? Also I tried to manualy change the fan speeds and when the fan went under 600 rpm the speed on the BIOS went red. shld i be concerned?

 

Side question, is it possible to keep the brightness of the LED high while keeping fan speeds low? Cuz when i lowered the fan speeds i noticed the led brightness lowered as well. I kinda prefered the brighter LEDs which was why i bought these fans in the first place

 

oh and last question what are the optimal cpu, motherboard as well as HDD temps? I'm using 6500, Asus H170M-E D3 and HGST respectively

The red highlight is just a low speed warning on that fan header, there are settings that can change that setting inside the BIOS. As for controlling the fans and temps you can setup temperature based fan curves using AI suite or directly inside the BIOS.

 

For the LED's they will dim as speed lowers there isn't a way around that without modifications, as for temps for components at load the CPU should be <85C, HDD/SSD <60C for the most part. The motherboard can vary with the components on it.

hahaha sorry maybe i wasn't clear but i actually meant what speeds shld i set my fan at?

That's up to you, if you want better temps more RPM and noise basically. I would go as low as possible first if temps are good.

In the end case fans don't change component temps that much. You can be fine with running all your fans at slowest speeds. This will mean higher temps on components but not anything close to danger levels on normal well ventilated ATX case.

 

You can disregard any warning that shows rpm. Only temps matter if fans are working.

 

LEDs will dim when you lower fan speeds. Reason is that they are connected to same power cable. When you lower fan speed, you will do that by limiting power fan gets. Less power for fan, less power to LEDs. Solution would be getting fans that have own power connectors for fan and LEDs. Or get LED strips instead.

 

Optimal temps for CPU are t0-60C under load. You can go up to 75C easily under gaming or full load. Warning temps would be around 80C. Mobo temps are irrelevant. For two reasons. They are passively cooled by case and CPU cooler. And sensors might be bit off. You are looking at 60-70C under load there. HDD is also mostly passive cooled by intake fans in most cases. You are looking at temps close to 40-55C.
