Bottom Mounted PSU, fan facing Up or Down?Case is in carpet.

[litwicki24]

I will add to my case non reference card Evga Gtx 980 ACX with 2 fans. So question now. Which way of plug PSU will be better,with fan facing up or facing down? Which way should i go ,for better airflow and better GPU temperatures?Damn i am confused. !

the fan in the psu sucks air into it. If you have tower on carpet put the psu up. If not put it down. Risk of having psu up is dropping objects into it. If youre worried about the gpu heat have stronger fans at front of case and weaker 1s in back to reduce dust. You can take case to a shop and have them cut holes in the side panel with points to screw down intake fans.Plain and simple

There is enough room under the case to provide air to PSU?
I need to add some material between the carpet and the bottom of the case for improve room for airflow to the fan in my psu? ( like sheet of cardboard, a piece of wood, or book )
I must raise the case up a couple inches and put something under it? Or not? What you think about that?

Ok a piece of wood plank to elevate it and reduce chance of carpet fibers from getting in

OP go to your local hardware store and look in the dumpster for a clean piece of plywood or a couple of boards big enough for your case. Generally hardware stores will cut down sheets of plywood for customers and if a piece is too small to sell they toss it out. Setting your PC on carpet is a bad idea and you can solve the problem for free so why not.

I don't have a shaggy carpet or even low pile carpet.. Anyway 64k , can you give me some picture ? I want to see. what it should be like case with piece of plywood under ok?

So do you have a hard floor then?

You can cut down the piece of wood so that you probably won't be able to see it. As long as it's big enough to sit on the case stands. It's not just the air flow to your PSU that's the problem. PSUs have been known to go out with sparks. Why chance a burned spot on your carpet.

He's got an area rug. Only the OP can know for sure. He's going to have to put his hand down there and feel if airflow is going into his PSU.

 

[eidairaman1]

Gotta keep any type of rug/carpet away from bottom of case, plus over time fibers from rugs do get scattered. And front intake fans do pull fibers in.

What you mean "It's not just the air flow to your PSU that's the problem"?So i dont have enough room for airflow to the fan in my psu? There is not enough room under the case to provide air to PSU? Can you explain?

Do like rtwjunkie said and put your hand behind your case where the PSU exhausts air and see if there is any airflow and then lift the rear of the case a few inches off the rug and see if the airflow goes way up to determine how much sitting on the rug is constricting airflow if any. Until you do that we can only go around in circles with you trying to figure something out that will take a couple of seconds for you to find out for certain on your own.

[WildChild2]

elevate case off of carpet, get filters, and mount so PSU draws air in from bottom....need cool air to cool PSU...not warm case air...

 

[eidairaman1]

How about you take better pics of your case. No matter how you slice it carpet/area rugs are bad for cases with bottom psu intakes, it introduces fibers/hair/skin/dust into the fan of the psu thus creates more heat, doesnt allow for proper airflow, plus increases failure rate of psu and a fire hazard. Its like you putting a plastic bag over your head, or sticking your nose into the carpet. Elevate the case with a thick book if sitting on carpet/area rug. Or get some plywood or plank. We have expressed this already several times stop being a burrow and do it.

Last question. Can you look at that picture?:This is the way what i want to plug my psu on that case.

Is here enough room for airflow to the fan in my psu? There is enough room under the case to provide air to PSU?
I must raise the case up a couple inches and put something under it? Or not? What you think about that? Thx

Do the above and you will know. A reasonable person would do that. It would take you 1/10th the time it takes for you to make one post about something only you can answer with certainty. Look at all the time you are posting the same question and all the time members are spending trying to help you and you won't even put your hand behind your case and check for airflow from the PSU. That's not sensible so I'm done with this thread.

 

[eidairaman1]

Since it appears youre on a hard floor you'll need to clean often to keep the area around your case dust/hair free and clean the intake often or elevate the case off the floor, i set my tower up on my desk to reduce dust intake.

You have your answers now stop worrying and implement them.

I think take 2 blocks of wood up to an inch thick and as wide as the case And set one accross the back end, and one at the front end, and you will be fine.

my god this thread ... the fail ... the ignorance the ... plain old what in the fuck ... come on people this is not rocket science

 

[litwicki24]

Can i put under case something like that ( cardboard )?

 

[chuck216]

Best way is with the fan facing up drawing air from the inside of the case and out the back of it. Sure it uses the warm air from inside the case, but no chance of sucking carpet fibers, dust etc into the PSU and it also acts as a second exhaust for case ventilation, the more airflow you can get the better.
