Anyone install the Zalman 9500 on a K8NS 939 board?

I have a Gigabyte K8NS Ultra-939 nForce3 board with a 6800GT in the AGP slot. Was wondering if anyone can confirm that the Zalman 9500 will fit?

Thanks!
 
I will! I will take the time!

Thanks 🙂

Edit: ok, well it tells me that the coolers is socket 939 compatible, but I knew that. What I am looking for is someone who has put it on this specific mobo.

Edit: nm, I found it. Says it is compatible, but Newegg is out of stock. Waah. Thanks for the tip.
 
Before you buy, make sure it comes with a metal backplane (the metal plate that the cooler screws into). Apparently, Zalman isn't putting one in the kit anymore, and the Gigabyte (I have the same board) uses a plastic snap mount.

If you need to get a backplane, Thermalright, Swiftech and others sell them for a few bucks.
 
Do I absolutely need to pull the mobo and put the backing plate on? The cooler is only about 3 oz. heavier than the max spec for the socket.
 
I just installed a Zalman 9500 on an Epox 9NPA+SLI this weekend. I used the standard (plastic) backplate with no issue. Mine is running around 38c in Windows basically at idle. No overclocking yet, using Artic Silver 5. (The idle temps have dropped 2 degrees in the last 48 hours as the AS5 has begun to set.)

My concern with the new Z9500 is that the base of the heatsink is not flat. It has a curve to it. When I sat the heatsink on a flat surface, it rocks back and forth. I did some searching, and there are several others having the same issue. Even the Frostytech site noted the problem in their review. Not sure if all are like this or just a bad initial batch. I was somewhat hesitate to put on my $900 dollar AMD 4800x2, but went ahead.

If the base was flat, I think you could get into the low 30c's. I had purchased a XP-120 but it wouldn't work on my board. It touched the first RAM slot. I am ordering the SI-120 to see if it will work.
 
You could always lap the base I guess. But aside from that, your un-oc'd idle temp isn't making me all happy inside. My 4400+ idles at 42 deg. C o/c'd to 2.53 ghz, with a cheesy little $19 Thermaltake Venus. I'd hate to spend $79 to get 4 degrees off. Of course, I want to go for 2.64 ghz, so I will probably have to do something.
 
If your case has adequate ventilation and if your ambient temp does not exceed 25C, then you should expect to see an idle CPU temp around 30 to 33C with ANY decent CPU cooler. Some MBs will report an errorneous CPU temp.
 
My Zalman 9500 idles at 27c......load is between 37c--39c
My ambiemt temps year round are approx 70 degrees farenhiet or 22c......

You should see a huge drop in your idle temp....my idle temp with stock intel hsf was 46c.......and my load temp was 74c.

Good Luck!!
 
Cool 🙂. My ambient temp in the case atm is about 43 deg. C. The ambient temp in the room is obviously a lot lower. I think the airflow is probably decent, since it is a big case without a lot of obstructions, and four fans running (two 80mm front, one 120mm rear, one 120mm psu). I can still do better on the cable management, and definitely do need a better cooler.

Also, I have the textbook under-desk situation, where the heat builds up. I am thinking of drilling some big holes in the backboard to let the hot air up and out.
