Water Cooling running max and loud even at idle

[Tyrianes]

Hi people, i hope somebody can help.

Hi ppl,

Here is my issue: I've installed a new water cooling unit for my cpu. Well the installation was pretty difficult. When i start the pc, i get a cpu fan error and the cooler get very noisy (fans speeding up way too much for nothing). The cooler seems to work (im idle at 25c and max 41 while gaming). Ive connected the pump cable in a channel pin and the cooler cable in the cpu_fan pin. I just dont understand where is the problem 🙁.

Specs:

Watercooler: Lepa aquachanger 240 (Enermax)
CPU: Amd fx 8350 (not OC)
Mobo: Asus m5a97 r2.0
GPU: Gigabyte r9-290 windforce oc 4gb
Ram: 8gb adata

You should set a fan profile to link fan speed to cpu temp. You can set it either in bios or with AiSuite software from ASUS.

Hi Neutr1n0, thank you for your time.

I saw in my Bios that fan speed value was n/a while the chassis fan speed are running at 2600 rpm! When i putted the chassis fan speed to the silent profile, my pc became silent and the watercooler fans were running at a lesser speed. I think that my watercooler fans arents detected as cpu fans but as chassis fan and i really dont know why.

I'll bet that the stock supplied fan is a 3pin fan, not a 4pin pwm fan. If this is the case, you will probably not be able to control the fan through the cpu_fan header as most times that header is only controlled via pwm, not analog. The fix for this is very easy with Asus fan xpert. You need to do a few things.

First, put the pump wire on cpu_fan. Then put your fan on sys_fan1.

Second. Go into Asus fan xpert, and run through the wizard with the side panel off. Pick the cpu fan location at sys_fan1 and set your curve as wanted.

Alternatively, you can use SpeedFan. Once you figure out what fan is what, you can set fan curves for sys_fan1, but use the cpu temps not the default address temps, then set your curves as wanted.

All that's free, except for time.

Most expensive option is junk the 3pin fan and buy a 4pin pwm (@$10 to $20) and use that instead, hooked to cpu_fan header, which will give you cpu fan control.
