Asus M4A78T-E mobo space worries with this current system build

I bought this combo deal from Newegg.

AMD Phenom II X4 945 Quad Core CPU + ASUS M4A78T-E AM3 AMD 790GX HDMI

ATX AMD Motherboard + CORSAIR XMS3 DHX 4GB DDR3 PC1600 RAM + SAMSUNG

Spinpoint F1 1TB HD - $400 (AR + 8 s/h)

First question is the stock HSF that comes with this CPU good enough

until I can afford a decent water cooling solution or should I upgrade

it, if I'm not able to replace it with in a couple months. I don't plan

on doing any OCing yet if I can help it, can I just turn up the fan to

keep the CPU cooler? Like will higher temps decrease the lifespan of my

CPU?

If I was to get a HSF, I would get this one from Noctua with an extra

fan for the push/pull config. My only concern with this fan or any

other fan that has the same configuration would be if it blocks my ram,

I've read one review saying that it mite or will. I would just like

some confirmation because there doesn't seem to be much HSF that would

fit, if it did. I need some confirmation on this would be of great help

if anyone knew someone with this same mobo + wide hsf + tall ram. If

you know any good HSF alternatives that would help a lot.

The case I currently have is the Thermaltake Xaser III V1000a, I'm a

little concerned on how hot my room gets with a ceiling fan at high and

window open. Does the room temperature greatly affect the air going

into the case, if so should I try to cool down my room? Sometimes my

room gets really hot for being so small and little airflow from the

outside. The ceiling fan stays at max speed but still doesn't cool down

my room enough.

I have an Allied 450w switching PSU, it's really old but worked out. I

just plan on using that for now is there any risk in using it after

it's aged a few years? I know I'll need more power once I get a GPU,

this is only temporary. I plan on getting the corsair 750w PSU, any

other suggestions is welcome. The reason I want 750 is so that I can do

crossfire in the future. They seem to be the most reliable PSU as far

as reviews go and stability. I was also recommended the OCZ

stealth-stream modular, but it seems the Corsair is better.

I've decided if I was to get a new case it would be the HAF 932. Should

I upgrade the Xaser III, I know it's older but it still seems to be

decent as far as air flow and room goes.

Last thing I'll get is a new GPU, right now I have a really old 7600

gt. Plays CSS/L2 and other high end games with lowest settings.

Please feel free to make suggestions, maybe I should sell that ram. I

would really like some Kingston Hyper X. Than my HSF spacing would be

free, think anyone would buy it.

 

yeah if your going to be overclocking then you will definitely need a better hsf.
Also yes your room temperature will affect temps of the components so you will need to cool your room down somehow.
It's also a good idea to get a corsair 700w as 450w is nowhere near enough to run a quad core cpu and radeon 4890
