from completed build My first Build $1000 CAD

Only have 2 slots for fans, i need to buy a splitter in order to have 3 fans working

Okay, this mobo is adequate but nothing to write home about. One - count it - ONE chassis fan and one CPU fan. I bought a cheap fan hub to compensate for the time being. This board rides the struggle bus above 2666 MHz on RAM. I have heard of a few people cracking 2999 but I have yet to sit down and finitely tweak to try and get there. I'm also not sure if this board is ideal for squeezing the last bits of OC juice out of your CPU. Lack of heatsinks, maybe? Look good in a black scheme though.

Motherboard Asus - PRIME B350M-A/CSM Micro ATX AM4 Motherboard. This and the ASRock were the two cheapest B350 Motherboards. I knew for longevity I would want to have the ability to overclock, so I focused on the B350. The ASUS seemed like a better, safer bet, and I grabbed it when it went on sale $20 off from retail. The combination of my case and the location of pins didn't agree sometimes, so cable management was ugly.
