Arctic-Cooling Accelero X2

THE BAD:
Cooling performance not sufficient for X1900XTX. Blows air down onto the motherboard. On boards like the DFI LanParty NF4 UltraD that have a chipset directly beneath the exhaust, this is a huge problem.

SUMMARY:
I just got one of these cards a few days ago. I regret to report that it is not up to the task of cooling my Sapphire X1900XTX, even at stock clock speeds. Forget about any overclocking. After installing this cooler, the idle temps on my video card went up from 50C to 56C and my load temps went up from 90C to 98C. To make things worse, the idle temp on my chipset with the stock DFI cooler and fan went up from 42C to 50C, and the load temp on the chip set went up from 52C to 61C. Unfortunately, when the chipset gets this hot, that little fan on the chipset cooler starts spinning alot faster (default speed is around 4000rpm; at 61C, it was spinning at over 7000rpm). The sound that chipset cooler makes when spinning at over 7000rpm is pretty loud, negating the silent properties of the Accelero X2. This cooler may be ok for an X1900 or X1900 AIW, but I don't think it cools well enough for an X1900XT or X1900XTX.
