I am building a 600 dollar PC, and had a pretty strict budget. It came in right at 599 when I added in some artic silver thermal compound. However, the spare fans I thought I had, are actually in use. So, all i have is the one 120mm exhuast fan that comes with my case.
i'm trying to figure out with this build how many extra I may need. Also, what would be the best places to mount them If I do need more. I also don't plan on overclocking.
Also, this is my first full build. I've toyed with PCs for years, just always had a PC that i was upgrading, never built one from ground up.
I've been reading over the step by step guide just to get familiar with a few things, especially cpa/mobo/heatsink etc, as this i've never done.
I was seeign if anyone had any final pointers or suggestions for me. Type person I am, is I love researching and trying to find out every little detail about my current project, so I apologize for all the questions!
Overall you are in good shape with that build. That GAMMA case can fit up to six 120mm and one is included (rear exhaust). Maybe add fans to the front (intake) and side (exhaust) and see where you stand. You don't really have a build that will generate a lot of heat so I wouldn't worry too much there. If it were me, I would add a $30 CPU cooler and the front intake fan and monitor temps. I would also swap the memory out for some G.SKILL modules...
If the memory works and passes all tests, then it will be fine. The Crucial memory you listed are generic Crucial modules. Fine and all (assuming they pass tests), but the G.SKILL are more proven, have heat spreaders, and are the same price (before state taxes).
If the 120mm fans you are getting are silent, then get a minimum of two additionals. Five would be nice (two on top, two on side and one up front), but being silent is the key to filling up the case.
One intake fan in front, two exhaust on top, and one exhaust / intake on the side. You may want to play around with the top and side fans to see what configuration gets the better temps. Any config would be fine, but it can be optimized with a little time...
Which adapters? The Rosewill fans have a "3 Pin" power connector that typically will plug into your motherboard. Your board will have two, or maybe three, available ports which are most likely already taken with the CPU fan and rear case fan. The "3-pin to Molex" adapter will allow you to plug the fan into a more readily available connector on the power supply.
