Thank You Zalman!

[WobbleWobble]

I installed the Zalman CNPS-7000A Cu a couple days ago and I was playing around with my system last night. Nice and quiet I thought, but the temps were bit high. One day later, I open up my case and notice that my CPU fan was caught in some wires so it wasn't spinning! My diode temp was still below 70C, so I wasn't too suspicious.

And I was running this system, pretty much idle, but it had been on for over half a day.

No other fans were on in the system at the time except for the Panaflo L1A in my PSU.

My XP2500+ was overclocked to 2.1GHz at 1.775V at the time too.

Great HSF

I believe the Zalman 7000 can cool 120 watt heat dissapation eeeeassssaaaaaaaaaaaaaayyyyyyyyyyyyyyyy. That means your 2.4 @ 3.6 if you wanted to. All you have is a 2.1 xp. The zalman is overkill my friend, thats why its an amazing hsf.

I actually also did the same silly thing, except with a Zalman CNPS3000+ AlCu with a Thunderbird 1.2GHz. Socket temp was 70C, but the CPU still works flawlessly. You'd think I'd learn by now!

Better than silent boost?.... I may consider one for my K8.

 

[WobbleWobble]

Funny you mentioned the Silent Boost. The CNPS-7000A replaced my Silent Boost

I made the wrong choice the first time.

I knew you had a silent boost... thanks to you I bought one , and thanks to you I'll buy a Zalman
For my new K8 I'll go with the Zalman then. I still love my silent boost with ducting mod though

 

[WobbleWobble]

Hehe!

Now many thanks you to you maybe I'll buy a K8 soon

Let me know how the ducting mods go! I would like to know how effective ducting is.

They make very quiet psu's too. I just installed a 400w silent unit that is, in fact, virtually silent.

 

[Achtung]

Mine is on the way... can't wait!

Interesting. I just put in a thermalright 900 and a medium speed 92mm panaflo, and to be honest I'm disappointed in it's cooling. My AX-7 and 80mm panaflo actually did a better job (former peaks about 45 C and now near 50). I may have to give that Zalman a second look and ebay the 900.

Ducting mod lowered my temps 5C with the silent boost. It lets scape de cpu from taking 9700pro's hot air and makes it face the side intake fan... It was a nice purchase for 1,63?

 

[WobbleWobble]

Did you buy those Thermaltake Ducts or did you make your own?

 

[McArra]

Bought it (Thermaltake). In a shop here it just costs 1,63?... nice price I thought and bought it

Some pics:

I replaced Smart fan II with the stock Silent boost panaflo and achieve the exact same temps.

 

[WobbleWobble]

That looks pretty neat! What about putting 2 together and pushing the air out the rear exhaust?

 

[McArra]

If I wasn't to sell this machine I'd try it, but I'm selling it soon

As the previous owner of both an ax-7 and an slk900a, let me chime in with my 2 cents.

The 900a blows away the ax7. The ax7 is decent, dont get me wrong, but simply cannot dissapate heat even remotely as well as the 900a can.

I know it should do just that, but it doesn't seem to. I have an XP2600, not overclocked. My AX-7, with a variable speed YS-Tech 80mm fan on top (max of 48.7 CFM per the SVC site), kept about 45 degrees C or so after a few hours of SETI @ Home. The YS-Tech fan was not turned all the way up either, it was ~perhaps 2/3 of the way on the knob adjustment range, just about the point of it being audible. With the fan cranked, I could keep it right about 40 degrees or so, but that was too noisy to live with. Now, I have the 900, and a 92mm Panaflo (max 48 CFM also per the SVC data on their site). The Panaflo is running full speed - and I have to assume moving a lot more air than the 80mm from the old setup. I stay right around 50 degrees C now, after the same test - which is just looking at the temps after about an hour of running SETI and surfing the internet.

I've gone so far as to pull it off, reapply the Arctic Silver, and put it all back together. The temps, before and after, are from MBM5 inside a Sonata case.

I'm just not impressed with the 900... All I can think is - something must have changed in how it measures temps, my heatsink is busted (yeah right), the fan isn't running correctly (though the RPM wire readout has it right about max rated speed), or it's not installed the right way (possible, but I've done it twice now, and not too n00b at hardware anymore). I guess as long as it keeps under 60 or so, whatever... at least it's quieter than before, that YS-Tech fan was starting to get loud in the bearings.
