Pros: Purchased for dying stock fan on a ATI X850. Much quieter while keeping the card nice and cool. Easy to follow instructions, for an uncomplicated process.

Cons: Would appreciate an in-package comparison of the performance of the included thermal grease relative to other brands. Stuff is cheap either way, so not by any means an issue.

Overall Review: Second Zalman fan purchased (different VG cards), for a twice satisfied customer. Dying stock fan on X850 was idling at 55C, hitting 85-95C+ (at which point I immediately shut down the computer). Card now idling at 44C with a peak of 65C running Doom 3 at highest settings (and in a case with admittedly poor airflow).
