1115790 2010-07-04 12:52:00 If you have (if it came with the plastic funnel thing, that goes over the CPU), did you remove this, or leave it there? There's a lot of forums, saying that the fan on the side should blow air in (so it blows air on the CPU, and the videocard - which probably wont work, since I've left this funnel thing on), and out.

But none of them really say, anything about whether to keep this plastic funnel thing on as well.

So:

1. Should you remove this plastic funnel thing, before putting a fan on the side of a case?

2. If you do remove it, then which way should the fan on the side be blowing ?? In or out?

3. If you leave this funnel thing on, would the fan blow out? Since as above, if its in, its not going to go far is it?

The case (not this one), has a fan on the front and back (the front is smaller than the back, and the side fan (which are 80mm)

1115791 2010-07-04 19:44:00 I don't have a side fan but do have a tunnel to the side to the CPU on one case I left the tunnel on. The other case is meant to have the tunnel but it was broken when I got the case second hand so didn't bother putting the tunnel on, this second case contains an old P4 3.0Ghz used as a backup server with 3 HDD's and runs quite warm so I put a front and back fan in as extra cooling gary67 (56)
1115792 2010-07-04 20:20:00 I have a fan on the front going in 2 on the side going in onr on the back going out and two on the top going out, all are 120mm and all run at 2000rpm apart from the back one nedkelly (9059)
1115793 2010-07-04 20:27:00 I have the funnel intact with no fan (as it's positioned directly above the CPU fan), and another vent which is positioned about 70mm below the vent with a fan sucking air in. somebody (208)
1115794 2010-07-04 21:49:00 Modern cases have proper air-flow management and blunt instruments like a funnel tunnel are not necessary now. DeSade (984)
1115795 2010-07-04 21:55:00 I generally find that it hampers rather then helps airflow, but it does depend a bit on the case and where the fans are positioned.

There is a spot for a fan in the side of my Antec Twelve Hundred, but I think anyone who actually put one there would be a bit mad, the airflow through that case is amazing and that would slow it right down.

1115796 2010-07-04 22:33:00 I recently got a new case for my gaming system.
I read a lot of forums & reviews re cooling first.
I now have a medium tower with a 120mm front intake fan & 120mm rear exhaust.
They are controlled with a auto 3 speed fan controller.
It is extremelly quiet & will only to 2nd speed on a hot day.

1115797 2010-07-04 23:07:00 Thanks for the info folks . Well the front fan is positioned where the hdds go .

And the back one is above the videocard (the slots for cards are on the bottom) . I cant actually remember what the model of the case is .

I think I'll remove the funnel then, and leave the fan there . And change the direction of the fan (make it blow in, instead of out) . Since most people its better (if the funnel isnt there) . So, it blows on the CPU/videocard . Soon find out when I get it going . I'll check the temps in the BIOS

There's not a lot in it . Just the ram, one videocard, firewire card, and its a 2 . 5 dual core .

1115798 2010-07-04 23:09:00 You mean make the rear fan blow in? Normally it would be the other way, cause it extracts the hot air off the motherboard and graphics card. If you were to do that, make sure all the fans are blowing the same way, the idea is to get a flow going (one way or another). The general idea is front to back, but I guess it could work the other way. Can't see it being as effective though, and the hard drives would get hotter. wratterus (105)
1115799 2010-07-04 23:30:00 No the side fan will be blowing in. The front will be in and the back out. I decided to remove the funnel, because I've looped the 24 pin, so its like this [ the bottom of that bracket is plugged into the mobo connector, the middle of that bracket, is resting on the side of the back fan (the top lies under the PSU fan), and if the funnel is attached it hits the top of the 24 pin connector (which has sleeving on it) Speedy Gonzales (78)
