Hello all,

i bought the ATCS840, and i going to move my rig (signature) to it, what i want to know. i see that i have two option for installing the radiator on top:

1. install it on the current 2X230m fans.
2. use the bracket and install it it with 3X120mm fans.

my current setup is push>>pull, i going to do the same with the ATCS840, somebody know what will bring me the best performance ?

>>>air flow>>>
3X120 - RAD - 2X230
OR
3X120 - RAD - 2X120

or its doesn't mater, as the performance different are not critical.

thanks ahead

I have them in both locations in my 840. Are you watercooling your vid card? If you are it won't be a big deal for it to be on the top since there wont be much heat being dumped inside the case. If you are the mounting it in the front would give you better temps. One thing to be aware of is you might have to redrill holes in order for it to fit on the front HD cage. The bottom tank of your rad will hit the bottom of the case and the holes won't line up. Also it's a pain in the ass to change things in the 5.25 bays when you have a 360 rad on the cage.

230's don't have high enough pressure to work with a rad. You need to use fans made for radiators. Your Yates would be perfect.

He is right. I tried using the stock 230s and they did not work well. This is what I ended up doing:

Man, you'll be a lot happier with GT 15s than those Yate Loons. Other than that, it's coming along just fine.

The GTs are nice, but I think I have enough rad surface area to get away with the yate loons. I run them at half speed using a fan control, and my temps do not drop even if I crank them all the way to high.
