Would not go with OCZ Fatali1ty.... Only 3 year warranty. In three years, you could be in the same situation as now. "Ah crap my PSU is old, no warranty on it. Should I risk using it with my new shiny PC or not?" and OCZ isn't a great PSU brand. Any of the below is a much better choice - at least 5 year warranty, better quality, more room for future builds.

XFX core Pro 550W http://www.newegg.ca/Product/Product...82E16817207013
Corsair CX600 V2 http://www.newegg.ca/Product/Product...82E16817139028
Corsair TX650 V2 http://www.newegg.ca/Product/Product...82E16817139020
XFX Core Pro 650W http://www.newegg.ca/Product/Product...82E16817207014
Seasonic S12II 620W http://www.newegg.ca/Product/Product...82E16817151096
Corsair HX650 http://www.newegg.ca/Product/Product...82E16817139012 <-- modular, 7-year warranty... talk about long term investment.

You can check for yourself if you can get any of those for cheaper from NCIX.

Good luck 😉

the warranty doesn't really matter to me, whether it last 5 days or 20 years. i just need a good psu, i think the ocz fatality should be good, since it is a company that is well known and also it is better then my old psu, it is modular, i did check the review on it. unless i can get a better one, i don't want to spend more then $50 on it(the ocz is $44.99 with rebate)
 
I wouldn't buy anything OCZ anymore, least of all their PSUs. They have consistently shown themselves to be a company that does not take quality and reliability very seriously across the product line. This is probably the worst possible thing in an PSU. Stick to one of the Seasonic derivatives for your PSU (Seasonic, Corsair, Antec, XFX, etc.)

Yeah the top fan should be an exhaust just like the rear fan.

Disagree for two reasons. First, you'll see much better CPU temps with the top fan being intake because the CPU has a direct supply of fresh air. Second, you'll have less dust buildup in the case because it'll then be closer to positive pressure.
 
The top fan brings in air, half the current goes straight out the back, and half of it is opposed to the rising heat and the front intake air. That's not positive air pressure, that's just keeping the hot air in. If you wanted more positive air pressure, you'd put the 120mm fan on the side.

that's is what i thought, the fans are so close together that, most of the air will just go out and also hot air rises, so i would just be blowing it back in
 
Will be fine.

Just to clear this up, half of Corsair PSUs are made by Channel Well Tech, including the CX series. But the CX are still very good "low-budget" PSUs

Not really, especially if you have a big tower cooler. I was skeptical at first as well, but I tried it with my P182 and saw a 10*C drop (I shit you not) in CPU temps with no appreciable change in any of the other components.

:hmm:

Thanks for the info. I've got my R3 set up in a pretty standard way - intake fans in the front and floor, exhaust fans on the top and back. And a side fan for the GPU. It's balanced in a way that I can't really say if it's positive or negative air pressure.

The two top fans I have are 140mm. Maybe I'll try removing the rear top fan, reversing the airflow of the front top fan, and then see what happens. That would leave me with 5 intake fans and 1 120mm exhaust ... LOL. I'm a bit sceptical.

Two exhaust if you count the PSU. 😉

The R3 is a bit different than the P182 and is probably better cooled even in a normal config, so I would be really impressed if you saw 10 degrees.

My hypothesis is that the difference is more pronounced in cases with fewer fans. I've only got my 3 Noctuas turning at 7V in my rig, so every little bit can make a big difference.
 
i have built the computer, it runs fine, its overclocked to 4.47 ghz, should i overclock the memory from 1333 to 1600 or 1866, or is that dangerous, i got the 200mm fan in the front of the case, i got the normal 120 at the back, i got 2 fans on the cpu cooler(hyper212+), should i get another 120mm or 180mm and put it on the side, for my gpus and i got the psu at the bottom of the case with the fan pointing down

* A computer case has so many leaks, positive or negative pressure doesn't have a chance to build.
* What does it matter if the dust in the air is blown in (aka "positive pressure") or is sucked in (aka "negative pressure")?
IF a case could be pressurized, where is the pressurizing air coming from?
Hint: The dusty air surrounding the case

Why do you think that? If intake CFM is more than exhaust CFM, air is going to move out of smaller openings to normalize the pressure. If intake CFM is smaller than exhaust CFM, air will move in through smaller openings. It doesn't matter how many and how large openings you have, it's just a matter of scale.

Because dust that's blown in gets stuck in fan filters, while dust that is sucked in doesn't.

I don't understand this

You can try overclocking the RAM if you want, it's not dangerous. You're not likely to see a benefit one way or the other though. As for the fans, what are your current temps? If they are OK, you might as well leave it as is.
