Summary: It's extremely frustrating when you NEED to use a product, but nothing goes right. I had to fit this in a computer, with very tight space. This was the perfect VGA cooler for the job, low-profile, quiet, high performance. Unfortunately, there was no way the plastic thumbscrews were going to work. After a filing disaster, I decided to source my own hardware. I emailed Zalman asking for the thread size, zero response. So I got out the metric ruler.
Pros: Functions okay.
Cons: *Mounting hardware too big for my application. *Wires became unattached.
Summary: This Zalman requires extra active ventilation to cool decently. I have a Lian-Li PC-V1000 (which has hundreds of holes on the front and back, for ventilation) and the video card (8800GT) reaches 60C... idling. It recirculates the same hot air. Most stock cooler will expel hot air out of the back without the need for an additional fan.
Pros: - Looks good. Comes with nice little blue RAM heatsinks. - Comes with a dial to adjust speed.
Cons: - Doesn't cool well at all without outside ventilation. - Tightly packed fins make it easy for dust to kill air flow. - Isn't quiet on medium or higher fan speeds.
