Ok, so this is my first system build. I've borrowed a 400w power supply from a friend and I'm on my way down to Frys to get a new power supply and cooling. Wondering what's my economical solution here to make this an OC'able PC. My friend got the H100 on his HAF X case but I'm not sure it'd fit on the HAF 932, also I'm guessing I could use a less hot running power supply, this thing runs really hot and isn't quiet at all. Also is air cooling going to be enough? What's the safe peramiters? I ran Prime 95 on my system with the auto overclock on my mobo which puts it around 3.5GHz and it was floating around 72-75 with the current crap stuff I was running. So if I'm gonna OC this thing I definately need to rework it.
Also forgot to mention, I'm using a old crappy mid tower currently, on my way to pick up my used HAF 932 now to help airflow and stop to look at cooling systems and better powersupply. Fast responses are welcome, I'll check from my too smart for me phone thanks!

Depending on how high of an overclock depends if you will need the H100. Generally on newer CPUs' air cooling is completely adequate. I'd recommend the NZXT havok 140 or the cooler master hyper 212+ both are affordable and have gotten excellent reviews. Just get a good 500w to 550w power supply and your system should be just fine.

- 400W is not enough for overclocking ur system, upgrade your PSU soon
- get good CPU Cooler after market

If your psu 80+ gold silent pro hmmm very good, and u can use it
