Will Zalman CNPS8700 fit on Asus P7P55D Deluxe and Antec 300 case

Last response: in Overclocking

I've already got the case and in a hurry last night, I ordered a Zalman CNPS8700 HSF along w/an Asus P7P55D Deluxe. I've always been a Zalman fan and it seemed they had virtually nothing under the 450 gram weight limit that Zalman mentions compatibility with Socket 1156. This was one of the closest at 475 grams. (I'd hate to have to take and later reinstall a HSF each time I move my machine.)

Unfortunately, I realized that it (http://www.zalman.co.kr/eng/product/Product_Read.asp) might not fit due to the rather tall heat looking sinks near the CPU (http://www.bit-tech.net/hardware/motherboards/2009/09/09/asus-p7p55d-deluxe/2). Also, I'm not sure about the clearance now between the HSF and the 140 mm fan at the top of the case. The mobo manual says nothing about the clearances around the CPU socket.

Anyone use these two or three together? If they don't fit, can anyone suggest a good quality cooler that fits and is <=450 grams or not much over it?

Maybe I should've bought a CNPS 9300AT (http://www.zalman.co.kr/ENG/product/Product_Read.asp?idx=308) that Newegg doesn't carry but it's under the weight limit and looks like has more clearance? I would've needed to buy a kit to get it to work on Socket 1156.

The answer to your question is yes. The Zalman CNPS8700 is a low profile cpu heatsink that is only 66mm tall. It will fit inside an Antec 300 pc case and just about any other mid-tower case.

Here is a link to a technical review of the cpu heatsink:

Although the cpu heatsink can't compete with the 160mm tall, tower style, cpu heatsinks, it is a very good low profile unit.

I wasn't concerned about height, but most concerned about there not being enough clearance around the bottom to clear the large-looking heat sinks near the CPU socket along w/possibly blocking the 1st PCie x16 slot or running into RAM. Of secondary concern was the HSF running into the fins of the 140 mm fan at the top of the case.

Best solution

You mentioned the weight a couple of times, do you carry your desktop all the time ?
Don't have the Zalman, do have the board.
There's 115 mm between the rear heatsink and the first ram slot.
The PCIe slot won't be a problem,there's 70mm between it and the center of the socket, there may be a problem in the other direction as there is only 62mm from center of socket to top heatsink, that may interfere with the Zalmans lockdown lever.
Don't know how high that bump out on the Zalman is , but the heatsinks on the board are 31mm tall.

No, I don't, but still it's a pain. It's unknown whether the CPU cutout on the 300 will lineup w/the entire socket as well. I'd hate to remove the mobo too in order to remove the cooler.

Thanks for the measurements! I think I'm actually going to be fine based on http://www.zalman.co.kr/ENG/product/Product_Read.asp?id... . (Somehow my original link was bad).
