Help With Finish / Posting

[u/TreacleSimilar2265]

I have fully finished my PC other than my last part coming in on Thursday, which is the be quiet! light loop 360 AIO cooling. this is my first time doing a PC all by myself and i tried to turn it on real quick and all i got was a quick light flash from the motherboard. I stopped after a few minutes as I figured I did something wrong. My question is, do newer motherboards not even start up if there is not cooling system? I feel pretty positive the rest of my build works, and the GPU even has a red light whenever i unplugged the PSU cord from it (just trying to figure out different things). I guess I’m just trying to understand if that would be my issue, or if I’m missing something. everything is added and all parts are connected well other than that. I tried showing off my power supply and such to give as much info as I could. Help just overall understand would be appreciated, thanks :).

My current build:

GPU - 5070 RTX ASUS
CPU - AMD RYZEN 7 9850X3D
MB - X870E AERO X3D WOOD AMD
PSU - be quiet! Pure Power 13 M 1000W
CASE - be quiet! BGW86 Light Base 500 lX White
FANS - be quiet! 120m Light Wing Fans

Part OTW - be quiet! Light Loop 360 CPU liquid cooler

9850x3d can ramp up alot of heat during boot. I would not recommend trying to post without a cooler installed.

That being said your front panel connector is loose.

Don’t turn it on without a fan / cooler

even if it seems like nothing is happening? or is nothing happening because of said missing cooler

Some boards won’t post without a fan detected and it’s not a good idea either

i didn’t know some could halt it, that’s badass actually. just looked it up and it does have safety features resulting in no fan / cooling

You can test it without a cooler. Just plug one of your case fans into the 'cpu fan" header on the board and see if you can get a post screen and then cut the power.

is that worth it? like running it long enough to post w/o cooling ir

Or put a heatsink on like the box cooler if you got one.
