Hello,

second build here, just finished it, and some problems occured. Breadboarded but couldn't use a display, everything was ok except cpu fan not spinning when in cpu_fan header. Got everything together, and as the title says - GPU and its fans worl, chassis fans work, HDD works, cpu fan works when inserted into a chassis fan header, PSU fan spins and it works ( supposably ).

Components :

Mobo : Asrock Z170 gaming K4
Processor : Intel i5 6600k
Heatsink : Zalman CNPS10X Optima Heatsink and Fan
GPU : Sapphire RX 480 8GB
RAM : 2 x Ballistix Sport BLS2C8G4D240FSA 16GB kit DDR4 PC4-19200 Unbuffered NON-ECC 1.2V, total 32GB
Case : Zalman Z9 neo
PSU : Seasonic G650 650W 80+ Gold

Already tried everything from the list, and also :

- tried a different PSU, same issue
- tried BIOS reset/CMOS
- tried w/o GPU, same issue
- ....

The only thing that is not brand new is the HDD from a different build, but that doesn't matter.

Maybe it is something silly, maybe I am just dumb, but please help, since I feel like I wasted a years savings on PROBLEMS only..

If you need any more info please ask away.

Ivan

Checked the CPU today, even cleaned with alcohol, couple of 'bent' pins, fixed them up, not nearly as bad as they can be, cleaned the socket as well, new paste.. meh, I will keep looking for suggestions, if thst fails, RMA it is :/
Can't wait to having the CPU cleaned AGAIN for RMA, like one time wasn't stressful enough :)
