You already have it. Enermax cases usually ship with the side fan blowing out, so check it and turn it around if necessary.

Most enermax cases also have very tiny holes where the fans mount which restrict airflow and most of 'em don't have a real front intake...just a little slot on the very bottom with a lot of front usb cabling blocking the slot.

Don't set one of these cases on a carpeted floor.

Post back the model number of your case and we can give a better answer. Enermax sells a lot of different cases.

Got it. Nice lookin' case.

First of all, you do have a front air inlet. That's good.

If you look at the pics (or your case) you can see the tiny holes where the fans mount. If it causes a problem, they can always be clipped out.

Looks like you're in pretty good shape.

My power up psu lasted for two years with no problems and finally lost two capacators this summer.

Looks like you did pretty good for 60 bucks.

Just remember that fans on the front and side should bring air into the case and fans on the back and top should exhaust air.

the air is supposed to flow from the bottom front and out the back ones which are higher cuz heat rises and out the blowhole on the top if you have one, and the fan on the side should be an intake cuz it blows right into the cpu fan and makes a big difference. if you notice the PSU fan/s is/are blowing out so that proves that it has to be that way. thats how i got it.

I kno this old guy who runs his own comp shop and swears that the change from AT to ATX is that the ps suks air into the case to flow past the cpu and exit out the top rear outtake fan in ATX cases.
Although ive felt around my 2 ATX cases and 1 seems to blow out and one seems to suck air in, so i dont kno who to believe.
Still you shouldnt mess around inside ps's, so do what skip said, it works ;)

giggles,

Your friend is likely correct if he has a manufactured system (hp mostly does this).

More than one cooling system can exist but the good ol' cool air in the front, warm air out the back is generally the way to go.

You will see rigs intaking air thru the power supply when there is no room for a conventional cooling solution. Generally, it's a bandaid approach and doesn't work too well.

Well this guy has been in the business for 20 years. He has a mom and pop shop and he doesnt touch hp's not even for repair. He does builds for ppl and repairs and sells cool stuff, and he always tells me that the ps sucks air in. He's crazy and i kno this but he keeps insisting that the ps is intake. the 2 ps's that i mentioned above i bought from him in cases, and 1 definetly is outtake and the other seems to be taking air in through the ps fan. Still it works fine, im getting 34Cidle and 44Cload last time i checked and thats with stock amd hs/f. Of course my system temp's like 25C so its cool in there.

I have 1 dilema though, on that top rear outtake fan the air that comes is always cold. I dont kno whats up w/ it but it always feels cold to the touch.

My exhaust air is cool to the touch too. Means that it's under 37°C/98.6°F (body temp)and feels cool on your skin. My case normally has about a 5-6°C temperature rise from the bottom to top; that would put the exhaust air at about 31°C/88°F.

My psu exhaust is just very slightly warm and without having my thermocouples at home, I'd quess that exhaust air from my psu is around 38-40°C.

This week when my central a/c died, case temps shot up 10°C and the exhaust air from the case and psu was quite warm to the touch.

What you feel at the exhaust fan is perfectly normal.

Thanks cuz i was worried that that fan wasnt doing anything. Then again i have the abit nf7 s and the 2 power cords that plug into the mobo have to be routed all the way around the hs and down in front of the exaust fan, its a really poor design that halfway blocks that fan. And get this they had to position the headers there so that there would be enough room between the agp slot and the pci slots so that a big gpu cooler wouldnt block the pci slot below it. this also means thta the ddr slots line up vertically right beside the hs and somewhat block air there too. My ram is always getting a fist full of hot air directly off my my hs and it is keeping this air from dispersing. And all for the stupid gpu coolers!
