Overclocking my e5400 and gts 250 e-green, cooling fan

Ive only managed to overclock my CPU to 240 MHz with a max speed of 3253 MHz , and on idle its about 28 - 32 C and on load about 50 - 60 C ( tested on OCCT for an hour)

My palit gts 250 e-green is much worse, i can only get a max clock of 695 MHz, shader of 1500 MHz and Memory clock of 920 Mhz, anything higher is unstable. On furmark i get a max temp of 76C after a while but never get over 70C while gaming and this is the fan running at 80 - 100%

I have a GreatWall 550SEL PSU (550 watts) with about 32 amps on the 12 volt rail ( not 100% SURE but, 550 minus 160 (3.3v and 5v combined) = 390, 390/12= 32)

my cpu is at 1.3 volts and my gfx is at 1.2 volts and i cant change it from bios.

i was wondering if i should buy two 120mm fans to keep my pc a little cooler and dump some heat out of the case.

i want to put one near my ram and cpu to keep them both cool and one near my HHD and gts 250 to keep them cool too.

also should i buy a 3rd one to suck air from inside the case and blow it out the back?

also should i get this cpu cooler too?

pc specs:

e5400 OC'd to 3.25Ghz
MSI G31M3 Mobo
GTS 250 palit e green (about the same performance as a 9800 gtx)
2 GB ddr2 ram (PC6400)
550 watt great wall power supply
Win XP pro SP3
19" LCD at 1440X900
playing games such as GTA4, Bioshock 2, Last Remnant, and more games when they come out.

With your graphic card, I'm just supposing it's a relatively 'bad' chip in the sense it can't reach stock GTS 250 speeds, but I wouldn't be too concerned because it is a green edition. A few fans may help... but with your CPU it doesn't seem to be a temperature issue.

Having better airflow would certainly help in your overclocking efforts. Of course, you may need more voltage to get more out of your CPU and GPU. While your BIOS may not allow you to raise your CPU voltage, you could use MSI afterburner to raise your GPU voltage. Of course, you do so at your own risk :D .

My two cents :

Get 2 more gigs or ram, get some good fans to keep your case heat free. and may be invest on a quad if you plan on going with gta iv (my i5 750 is at 60% loaded with this game)

Other than that, try to push the overclock higher by giving a few more vcore juice. But as said earlier, at your own risk

I just noticed that you are at 3.25 ghz at 1.3 volt which is not good. I had a e5200 going at 3.6 at 1.35

I used to own a e5400 and those chips are really weird. I oced mine to 3.7ghz with 1.35v but it ran hot!!!!!. I even lapped the CPU but the chip reached almost 56C.....this is a dual core we are talking about...my i7 920 @ 3.8 hit 52 with Intel burn test.
you should grab some better cpu cooling and see if that helps.....cooler master hyper 212+ was @ 20.00$ (microcenter)

Try going higher with you clock and when it doesn't boot, push the vcore a tittle and so on

i cant change the vcore, shitty mobo, so its on auto and i can only reach about 3.25, i could go higher but then some errors start to appear
