I installed the arctic freezer 3 but now I get no signal and my gpu doesn't spin or anything. Pc in my sig. I get a red light on the motherboard. Any ideas? Could maybe buy a 12700k to test it?
 
What red light? Have you read you're motherboard manual to see what it means?

Is everything plugged in? CPU/GPU power expecially.
 
I’d try what @mickyflinn said and thus slacken the Freezer mount and see if it POSTs. Also, I would double-check the 8-pin EPS at the top and GPU power – easy to half-unseat while swapping coolers. Which red LED is lit (CPU/DRAM/VGA/BOOT)?
 
Fixed it. Me being a numtpty i put the back plate metal side down so was shorting out lol.
 
Although the cooler is loud and no rgb and the vram fan isnt spinning. I plugged it into a cpu header on the mobo.

Are you are using the all in one cable for the cooler?

If not have you plugged in all 3 of the cables, pump, fans, and VRM?

Have you plugged in the ARGB cable? (i know nothing about RGB, so that's all i got)
 
New problem...

Bought new arctic p12 pro fans to connect to my nzxt grid 3 fan controller but the fans don't spin. Pwm header, not sure why.
 
Up and running but temp's are worse than the arctic freezer 2 while running cinebench 23. I have remounted once and added more paste. How tight should you tighten the cooler?
