    75-80 is pretty damn good for a x2..... i've seen most usually sitting between 90-95... some as high as 105... (which imo is way to bloody hot..)

    i'm still waiting on a PSU... but i MAY try using a OCZ GamerXstream 600 watt and see if the sucker will even work at all ;)

    Kinda sucks i sold the HD4870 i had .... i was going to try a tri-crossfire setup...

    All the ATI card's I've had of late has been far hotter than all the nvidia's I've ever had -.-

    How can anyone have a card running at 90-100C...

    I'm using 55% via ccc.

    It started getting hot these 2 days so that definitely doesnt help.

    Hmm, Just remembered, I think I put the 4870x2 in the bottom slot of the Motherboard, that restricts allot of free space below the gpu. I'll put it in the top slot tonight I'm sure that will make a difference. using bottom slot makes it about 2-3 inches away from the PSU, which incidently blows right into the gpu fans.

    The airflow on the internal PSU fan should be intake ... the one exiting the case is usually exhaust.

    But if you have a case without a fan hole in the lower plate, you have to turn it over.. That was the case with my Antec 900 case.

    True Bro but I was referring to this posted above my post by nicnik.

    That fan isn't blowing into the GPU fans it is intake and drawing air from the GPU fans.

    seriously, that's really bad luck!

    I have mine running now, and I'm not sure if it's my psu that's not holding up. It could be. I'm using a moderately priced psu Hipower 800W, 20A x 3 on 12v rails. I want to make sure that it is the PSU that's not pumping enough juice into the 4870x2. Right now with the system overclocked at 3.6, rock stable tested fully and tested with my gtx 260 as well, I am getting little stutters in some games with the 4870x2 (crysis etc), and in some games I will get shadow corruption of some sort, the shadows will flash and blink sometimes. especially if game camera is moved, or after a reload of new area. Downclocking CPU back to stock will make the problems appear to disappear. However, I only found this out this morning and had only 5 minutes on the PC at stock settings so i cannot fully confirm that this is the case until later this evening.

    If it is for sure the PSU not good enough then that's fine. Any other way to test to be sure?

    GPU-Z shows the 4870x2 VDDC Current at 12.2 and under most games it hits 40A, and in crysis full load it reaches 50-51A.

    Hmmm if that PSU has 3 x 20Amp 12V power rails it might not be enough because you can only hook up 2 x 20Amp rails to the card. All I can suggest is make sure you are using a separate rail (set of PCI-E power plugs) for each plug on the 4870x2.

    it's 4 rails, misread the psu.

    using molex for 1 and 2 pci-e 6 pins for the 8 pin. so 3 seperate cables.

    It does have 6+2 well, but i tried it and it wouldnt boot into windows

    It could be the overclock that is causing it. although saying that I tested the same overclock a few days ago with the gtx 260 and it worked flawlessly. i do have to test more to be sure that running stock cpu + 4870x2 works fine with no stutters or shadow flickering; inconclusive with just 5 minutes testing.

    You need a separate cable for each plug otherwise you are only using one rail.

    So your hd4870x2 is working again?

    My combined PCI-ex rails are 36amps... but for sure, i should at least be able to install the ATI drivers without it BSODing under any case, even the windows supplied ATI driver. I just find it extremely strange that if i disable the primary adapter, the system won't BSOD, but then again when running like that, i'm only getting half the card working.

    I'm trying to get a more powerful PSU, but i was fairly sure that this OCZ GamerXStream 600watt would be able to muscle the load, considering it's more powerful then the PowerStream 600watt which only had 2 rails, running FAR more stuff.

    Maybe i'll hook up 2 500watt PSU's to a single rig and see what happens.

    I'm not sure about the OCZ 600. Firstly, it's not a certified psu for the 4870x2, but more importantly it may not be able to take the quad core overclocked over 3.8ghz, and especially if the 4870x2 is overclocked.

    power consumption of the 940 phenom and the 4870x2 is very high when u overclock them allot.

    thing is... i didn't have either of them overclocked.... .stock all the way around.. low power use.

    the hd4870 doesn't even have a chance to go into performance mode, can't get the drivers to install, i'm sure if it were it would have kicked the PSU's kill switch if it were a problem.
