SilverStone TJ09 Setup

[B737Capt]

I am building my new computer tonight inside a SilverStone TJ09 and wanted to ask a couple of questions:

1. I am installing a Corsair HX620W power supply. Should I install it so that the fan is on the bottom or top?

2. Installed a Noctus 120 Fan in the hard drive case. Should the airflow go up or down?

3. Installed 2 Noctus 120 Fans on the top of the case. I assume the best is for airflow to go out?

1. I would say install it so fan is facing upwards, but if there are vent holes on the bottom do it facing down.

2. Up

3. Up

3. Up

1. There are vent holes on the bottom for PS.

2. Up makes sense.

3. There are also vent holes on the bottom for the hard drive cage. There will be two hard drives in the top cage, the fan in the middle and two hard drives on the bottom cage. Still up?

I have a TJ09 setup, had it for a few months, and have tried several fan configurations.

1. Regarding the PSU, I placed my fan pointing up into the case. I don't like the idea of pulling dirt from the floor into the psu. Also, w/ the fan up it gives more air flow through the case, near my GPU. It's quieter too. You just have to be careful when working in the case so you don't drop anything into it. If you look at pics on this site, many people have it pointing up, even when they have vents on the bottom for the intake.

2. The placement depends on the placement of the HD's, and their "actual" temps. Measure the HD temps w/ software, switch fan directions, and select which one is best (lowest overall temps). However, there has been recent data suggesting that HD temps are not too important to the life of the HD, or HD failures!!!

3. I use the top 2 fan spots to do my final balancing of the case and cpu temps. You can, as I did, try several combinations here. Alot depends on which cooler you have on the cpu. W/ my 9700 NT, I have the top-front fan blowing in, and the top-back fan blowing out. This gave me the lowest CPU temps.

My entire case is ballanced to give a slight positive pressure to the case to keep dust out (slightly more air flow in than out). The video card fan keeps things moving nice.

Hope this helps.

For point #3 I have an Arctic Cooling Freezer Pro 7 if that makes any difference.

Thanks for your suggestions!

The only thing I could say/recommend, is if it has a fan that blows through the heat sink, point it toward the back fan so this back/rear fans pulls the heat out. After that, you can mess with the top fans (all out, all in, one fan in and one fan out, front versus back, etc.). The air flow dynamics of your setup will vary w/ the location of wires, ram, video card, etc. So once you get everything else set up, then test these positions.....test, test, test.

The top fans snap in and out really easy, so it's easy to test. Put the side panel back on during testing.

I really saw no more than 2 - 3 degrees cpu difference w/ various top fan settings. But, the affects on your GPU might be another matter!!

Oh, and another point on that positive pressure idea, there are alot of open grills on this case (back), so if you don't aim for pos. pressure, you can get weird air flow short circuits. You can see this w/ smoke testing (I used a cigarete) really easy.
