GPU Fan on full speed, sensors says 0 rpm

[Dakoka]

Hey guys,

 

Quick story

 

I just builded a brand new system for around 600 €, all the parts are brandnew except the GPU.

It´s a 1070 Zotac mini from ebay for like 150 € but the seller told me one of the fan (the left one) spins at full speed, I thought for myself this would be a Software problem or something that i could easily solve with MSI Afterburner.
Oh boy how could i be wrong. It´s like a jetengine.

 

On gpu-z and Afterburner the RPM sensors tell me 0 rpm but the fan still spins at full speed.
Even manually putting a fan profil in msi, it don't change anything.

 

I searched everywhere and didn't find anything that help.

 

Things I've done:
-DDU and fresh install of gpu drivers

-fresh install of windows + update

-renew the themal paste

-cleaned the gpu (was so filthy that the pcb where something was written was black)

 

Things I will do (planned)
-using a vga to 4pin pwm to see if the sensor in the fans is the problem

-perhabs using a different PSU

 

Toughts

-Bios on the gpu?
-Bios on motherboard (there are two new versions, but the installed is from 2‎019/11/27)

-if there is the sensors in the fan problem I will renew them

 

 

System:

If 1 of the 2 fans spins at 100%, i think it is more likely that the PWM cable on that fan is damaged, since i thing that both fans are connected to the same port by a splitter. It also may be that the fan pcb is a bit fried, it sound like a fan replacement is the solution..

This is happening to me, it is probably not the cable, most likely NVIDIA cannot reach the sensor located in your computer, it is a common issue especcialy with pre-built pcs
