Zalman 9700 and AS5

i just went from a Zalman 8000 to a Zalman 9700 using arctic silver 5
my temps with the 8000 under idle were 38degrees
and under a stress prime it was at 60degrees

with the 9700, idle is at 28-29
and under stress prime right now just started about 6mins ago is at 36degrees
Celsius that is
well see after about 2 hrs what it is at

one question i do have about the 9700,, when i first turn the system on the fan on the heatsink turns for just a sec and doesnt turn at all during bootup,,, starts turning when i actually boot into windows,,,
in my sig shows my mobo and equipment,,, is there something in the bios i have to change
i just dont feel safe it not turning,,, especially if im not logged into windows, after a restart,, means fan isnt going to be turning,,, that cant be good

wow..huge difference in degrees. That's really good to know since I have a 9700 coming in the mail tomorrow. I'm getting around 58c under load right now with my x24400 with stock cooler...so..obviously I'd like temps lower.
As far as the fan not turning until in windows, what temps are you getting in the BIOS? If they are low, I wouldn't worry about it.

not real sure what temps are in bios,, havent looked yet
i just stopped the test for a little bit so i could mess around in windows but the hottest it got was 38 under full load with Orthos
so that is about 20 degrees drop,,, almost doesnt seem real to me, but im using the same program and everything as i was with the other heatsink.

Are you using the Zalman fanmate or connected directly to a mobo header?

If you're using the motherboard header, it may due to PC health settings or Quiet-n-Cool.

I wouldn't worry about it too much.... both the 9500 and 9700 are all copper and are designed well enough to disipate any heat coming off the cpu for a few seconds without airflow.

The 9700 is a stupidly good heatsink.

I had problems with overclocking my AM2 4200 (low power) to 2.8GHz due to the temp hitting 68C under load using the default heatsink (not the heatpipe version, a bog standard ally one comes with the low power x2's). Fitted the 9700 to it and I am now fully stable and running at 45C full load.

The only drawback is that the heatsink is massive.

Alot of motherboards will turn off fans to reduce noise when the CPU is below a specific temp. As long as the fan starts up again when the temp rises then I would not worry. Under full load it would take about 60-90s to raise the heatsink temp up to the "very warm" range.

ok thanks for the info
was just worried about it getting hot when booting up with no fan to it
answer to above question, i am hooked up to the fan mate

i just got my 9700 hooked up last night. In the bios, before I was getting 38c at bootup, but now I'm getting 25-26c! Also, running orthos for 2 hours, the hottest I was getting before under full load was 63c and now I got 47c!! GREAT cpu cooler...
Although getting it on my motherboard was a slightly tight fit. Not the fan's fault though. I could have planned it out a bit better. I cut my knuckles up a bit on the fins when trying to get the lever on the retention bracket.
Kinda funny because at first, I was upset because bar to hold the proc on the retention bracket was oriented the wrong direction for my mobo's retention bracket so I'm like WTF. Then when I RTFM, I read that you can turn the bar and twist it into place between the heatsinks and then will work. Ok good. But THEN, the bar wasn't long enough! I could hook one side of the bar on the retention bracket, but the otherside wasn't long enough to reach! Again WTF? But, the lever has one side that you fit into the slot on the bar and it actually swivels just a bit. Hard to push on it while swiveling it, so I had to use a screw driver to push down on the bar while putting the lever into place. THEN it worked...heh...
So, 2 pints of blood later, everything is much better.

Is the fan turned all the way up or all the way down when you are booting up? If it's turned all the way down, it may just be the way your mobo handles the fan control. On another note, you may be able to find something in your bios to disable motherboard fan control of the CPU fan speeds. I keep mine cranked all the way up all the time. Cooler the better and it doesn't make any more noise than my PSU fan makes and I game with headphones so the noise doesn't bother me anyway...

I'd love to see some pictures of the Zalman 9700 NT on an Asus board, since I am about to build one. Evidently, it fits fine and obviously performs great. Pictures anyone?

The NForce fan on my A8N-SLI Deluxe finally went south, so I decided to upgrade the cooling all around. I did the SLI Premium heatpipe swap (easy as hell and well worth it temp & noise wise). Also picked up a 9700 to cool it all.

On to the PC pr0n (click for modem-unfriendly pics)...

Sweet lineup to the exhaust fan:

In all it's glory:

What is the SLI Premium heatpipe swap?

Is this something you can order from Asus or where? Yours looks nice.

I have a Deluxe and wouldn't mind making this upgrade myself.

It's the passive cooler from the SLI Premium ($15.00!!!). It is 100% pin/component compatible with the Deluxe board. I'm working on a 'how to' guide; but if you've ever used needle-nose pliers before, it's a no-brainer. It cools a LOT better than the buzzy stock nForce fan cooler, too; I was surprised at that.

Now that is sweet. I have a Zalman passive on the way, but I think I like the Premium solution a little better.

Thanks for the heads-up. If you ever post that how-to, please let me know. If I do it, I will post here as well.

Thanks!

do you think the 9700 would be an upgrade from my TT big typhoon ?
