Possible GPU temp too low?

I got a Zalman VF-900cu GPU cooler for my BFG 6800GT OC AGP. Lowered idle temps from 62 to less than 50. But after a while, started getting artifacts, and windows XP lockups. On boot, would get multicolored and chopped up text, jagged horizontal pink lines. Would work fine after a reset. Got progressively worse, so decided to put the stock cooler back on. Working fine now, temps back around 60 (used AS5 with the stock cooler) with no artifacting or lockups.

Is it possible for a GPU to run too cool? Or maybe the little heatsink taped ram sinks used by the Zalman cooler are not cooling the ram as much as the stock heatsink/fan, which directly contacts the ram? 😕
 
I'd think it was more likely you didn't mount the Zalman HSF properly before I'd think that either the temps being too low or the ramsinks would be the problem.
