I only wanted to add that this case finally arrived at the end of its "airflow modding" road (my next case will be a bigger one). tongue.gif
The results are excellent for an air cooled highly overclocked mid-tower rig.
Yesterday I've even managed to increase the speed of the Accelero Xtreme fans (bottom video card only) from auto (21% idle) to 40%-75% idle-full (gaming) with the latest version of the Speedfan.

Long live our italian premium software. thumb.gif

http://www.almico.com/speedfan.php

All this wasn't possible before with the CCC because it only works when gaming (crossfire related),and not even with the MSI AB due to the settings I'm using (always) having the two video cards synchronized where my upper 6870 Hawk is running in auto fan-speed.
Now I'm getting 34°C idle and 50°C max intensive gaming (overclocked) for my second 6870 (the lower one, gpu2), about 10°C lower than before (when loaded gpu) and 2-3°C lower for my Hawk (gpu1) that reaches now 70°C only when playing Batman AC dx11 maxed in cf overclocked (980/1140).

I just picked up two XFX 6870's that do not have voltage control which really sucks, is anyone able to run their non referenced 6870's at a 1000 mhz or higher 24/7. I was really looking forward to running these things at 1050mhz under water mad.gif

Are you using Afterburner? You have to manually change the configurations in the config file to get it to allow you to change the voltage.

I have used afterburner for years and tried Trixx with these cards to see if I could increase the voltage. But unfortunately after doing some research I found out that XFX left the voltage controller off the cards and the only way to increase the voltage is via the pencil mod which I will not do. I upgraded from 2 XFX 5770's and I was running them at 995/1360 under water with a voltage increase of 1.312. I was only able to get these things up to 960/1200 which is very disappointing, the good thing is that the cards are animals at stock settings and overkill at 1080p. It just hurts having all this cooling and not be able to push the cards further.

Thanks and have a good weekend guys.

Just receive my gigabyte 6850 OC too biggrin.gif


But I have so many problem with it...

TF2 don't run correctly, the GPU usage is at 25% and barely get 60FPS, with huge drop... With the same setting, my 4850 512mb gddr3 was able to do 200fps...

BF3 randomly have huge FPS drop (go from steady 60 fps to 20-30fps), in these moment, my gpu usage and my cpu usage both get from 100% each to 60%...

That don't sound right at all. I would try and uninstall driver, run driver sweeper, run CCleaner, and reinstall first before looking into other possibilities.

I have my HD6850 OC'd to 1000/1250 while playing BF3 and it's around 60 fps a majority of the time with drops to 50 once in awhile. Over 70 during light situations.

I already pass driver sweeper and did a clean install of the newest driver. Might retry again with ccleaner over it.
Maybe even a complete reinstall of windows 7.

What setting are you playing BF3 at?
