Fan placement question

post #1 of 10
Thread Starter 
O.K I got this case last night http://www.newegg.com/Product/Produc...82E16811147059 the rest of the goodies are supposed to arrive to day. As you can see the case has a 120 slot at the front and low on the side. It also has an 80mm slot above the 120 on the side and should be pointing where the CPU should be, it also has a duct coming off of it. Then there is a spot for 120mm in the rear. My plan is for 120mm intake in the front, also intake in both side positions... one will blow directly on the GPU and the other on the CPU. If I do that will the 120mm exhaust plus PSU fan be enough exhaust? I have a PCI exhaust I can put in if needed. I also plan to use this HSF, hopefully it'll fit. http://www.newegg.com/Product/Produc...82E16835186019 . I also have a question about the duct coming off the 80mm fan. It looks like it can be lengthened and shortend to move it closer to the CPU. Is this really needed or will just the fan blowing on the CPU be good enough. Hope this is all clear as mud

Errm well you've linked to about 80 cases to start with, so we have no idea which case you mean..

But you're generally right. Low and front for the intakes, high and back for the extractors.

Side fan with duct might be useful for CPU fresh air. Give it a shot, let us know how it turns out? One this about 80mm fans though is they tend to be awful noisy. And the side fan might deter airflow a little, but that's notsomuch a problem provided it keep temps down.

Ahh yes that's got it.

I myself would stick to 3x 120's.. One front, one side, and one rear.. Personally though, as 80mm fans make too much noise for me. But yeah, 3 120's should be more than enough. Hell, i only use two.


Also depends what components you're running.. Go to User CP, fill out a system, give us an idea of what we're working with..

I second that.

Ok, added system info. It's not built yet, waiting for the rest of the goodies to show up today. So just the 1 x 120 exhaust is sufficient if I go with 2 X 120 intakes or even if I go with 2X 120 intake and the 80mm?

Yeah that'll be fine with the 1x120 exhaust.. Gotta remember your PSU will have a 120 exhaust fan in it as well, so it'll more than balance it all out.

Thought I'd post some results. I went with 2 x 120 intake (front and side) and since I had an 80mm, I also put it in the side as intake. 1 X 120 exhaust plus PSU. CPU temps have been holding 28* - 30*c . Noise isn't bad in my opinion, I'm going to try disconnecting the 80mm this weekend and compare noise and see if temps go up much. I haven't really checked temps under load yet. GPU temps are 43* idle and 59* under load of 3dmark06. My 3dmark score was 9100ish, don't remember exactly. Is that ok for this rig. I haven't OC'd any yet.

Those temps look alright to me my man! My CPU idles in the 40's, which is too much for me.

I can't see much difference being made by losing the 80mm fan, aside from a bit of noise that is..


And as for your 3DM06 score, seems alright.. I'm just shy of 12k with my sig rig.. What's your CPU run at?

CPU is at 2.5 (stock) currently.
