Zalman CNPS9500 AT

Acid8000 · 03-17-2006, 04:25 AM

I hope I don't sound like a Zalman rep. I've made a few posts about their products...hehe free publicity.

Anyway, does anyone have information about the upcoming Zalman CNPS9500 AT? This cooler recently got added to the Zalman site, and I'm interested in getting one. It would be better for me as it has a non-LED fan (I have a case window but dislike LEDs), and PWM control. I don't really intend upon getting another cooler as the 9500 series seems to be perfect for my case's current airflow and in terms of size. My case has a side fan directly in front and behind of where the cooler will be installed. Hopefully it won't cost more than the current LED model. Google searches haven't been too information laden, unfortunately.

At 1.1lbs I hope folks really screw down their motherboards tight. Going to warp it otherwise.

Case example of warpage...

These HSF manufacturers need to keep within spec, or they're going to ruin motherboards. Some cases there's a high clearance between the motherboard tray/area, which can result in a 1/2" warp of the board, and then SNAP!

Unless that guy had another heatsink installed before the stock Intel heatsink should not be doing that to the motherboard. Also heatsink manufactors are getting more clevor in how the heatsinks are supported, whether by backplates or using the motherboard try directly.

Thing is simple physics. Mass x area. The supports don't adequately support the mass with a small footprint (area of the supports). To adequately support the weight, they would have to use more motherboard surface to prevent warpage, which is at a preminum due to capacitor/regulator placement.

Unless the motherboard manufacturers use a heavier PCB material (or heavier bracing around the processor that distributes the weight evenly), being out of spec will cause that damage. Intel makes a recommendation no doubt from testing what the socket can hold itself, and no doubt m/b manufactuers meet that spec (at least credible ones) but little more due to expense.

Pushing out of spec designs causes more problems, which factor in the pocketbook down the line (try reselling a warped board for a good value, for example), let alone breakage.

I don't get it. Mass times Area gives you g*cm^2, and as far as I know that does nothing. Unless you mean Mass / Area, then you come into is the heatsink sideways or is it horizontal, how much torque does it produce horizontal. According to Zalman the heatsink weighs in at 530g, and the 2 waterblocks on my Xeon rig weigh in at 329g each dry. Granted with the motherboard not installed in the case the board has a lot of flex, but the retension brackets have been designed to hold that weight without ill effects.
