^That had better be a joke. Those don't do a thing for cooling.

^ Eh agree. I have my fan speed at 85% and can barely hear it, I do have a lot of other fans making noise though.

The dead spot of the hub could be a consideration, you might try adjusting it so that that the gap between the cards is more aligned with near the end of the blades, but honestly I don't see that making a huge difference either. I don't know exactly what to tell you. frown.gif

Yea I don't see it helping much either. These cards get hot, and I don't think there is anything that can really be done about it short of more powerful, louder fans. (and TBH jacking up the fan profile would do the same thing much cheaper!)

In the summer temps can really shoot up even in good air cooling cases.

Also, you can get a 5.25 holding case for the HDDs and SSD, so you can free the front of the case for more air to come at the GPUs.

room temp stays at 75f, and I thought about moving the drives, but at this point I don't think it's worth the effort.

I'm going to try four 120s instead of 230 side fan. I suspect full blast will probably knock off a few degrees and having them turned down to appropriate sound level will make them as effective as the 230 tongue.gif

although the leds on the side will look cool...and that changes everything! laugher.gif

In addition to manipulate the fan (tagged to the HDD cage), let me suggest another 2 tricks to see if they will improve the thermal numbers of your two cards:-

1) From pic 1 below, it seems that the clearance between case and the rear wall is about 6''-8''. My experience says this is the bare minimum distance when no active ventilation is provided in that region to disperse the hot exhausted air accumulated.

You might try to provide a small fan (pic 2) to blow horizontally across that region to facilitate. When I had my 8800GTX SLI inside my HAF932, I used this trick to lower temp by 2-3C (or even more if the fan is positioned skillfully enough to provide additional 'draft'. This 'draft' factor is covered below.)

2) Read my thread below about providing a 'pull fan' for the graphics card. You can adapt the idea to fit your own situation. There are lots of variation here. Pic 3 is an example done by another member.

This method can lower the temp significantly. I have seen a 10C drop for both cards when someone constructed an enclosure (similar to the ATCS 840's but the fan aligns toward the slots directly) for his cards. My pull fan with shroud only lowers 4C though (but I am only using a 140mm slow spinning fan @1000rpm and my shroud is semi-open, thus pressure created is relatively weak compared to a fully enclosed shroud/duct).

My thread on external 'pull fan': http://www.overclock.net/air-cooling/1053718-thermal-management-outside-case-part-ii.html
