Zalman 7000/6000 HFS suggestion
« on: August 06, 2003, 12:48:08 AM »

I will be getting Intel 2.8 or 3.0gz proc. I need your suggestion on the HSF, which one is better: Zalman 7000Cu, or Thermaltake 11 :-?  Thermaltake is noisier, I would prefer quieter eaven if it costs more. I am looking for the temperature differences, if anyone owns the Zalman 7000 or 6000, or Thermaltake 11 (the "exhaser" edition) please post the temps and the processor speed.

The Zalman 7000 will be noisy too. I'm not a fan of the Radial coolers, having had a Tt Crystal Orb, which made a lot of noise. I had a Tt Volcano 7+ which was okay when in low, but a jet engine in medium or high. The temps on that comp were okay: around 30 idle, 43 load in low, it was a P4 2.8b (533 FSB) @ 3.2. I have 23 ambiant with airconditioning. I'm assuming the 11+ will be similar in noise and temps or possibly better.  

If you have good case airflow (i.e. a number of intake and exhaust fans) try the CNPS6500B-Cu. It's passive and quiet. PCtoys also makes a very similar product, which is cheaper. It's rated for P4s at 3.06, though I assume with decent case airflow it can handle OC'ed processors.

Your choice is HSF really depends on how much you want to overclock as all the coolers listed will handle the stock with ease. P4s run cool, and you probably could get a decent overclock on either, though I think you could push further with the Tt.

Well, when you assume.....
I did a little research instead of assuming, and here is what I found out:
The Zalman 7000cu is very quiet, only 41 dBA under load.  This is quieter than almost all coolers. Rise above ambient temp on a 27mm copper block producing 50W of heat is 14.1C whereas at 100W of heat  it is 27.7C
In comparison, the Thermalright SLK900 (probably the best air cooling avaliable right now) is a whopping 67.2 dBA with a Tornado fan on it, and has a 50W rise above ambient of 11.6C and 100W  of 20.5
If you use a quiet fan, like a Zalman 92x25 fan, it drops the noise down to 46.2 dB, (Still a good bit louder than the Zalman) and the temperature rises are 14.2 and 28.8 respectively.
So, in fact, if you're trying to go quiet, the Zalman OUTPERFORMS the SLK900u.  The Zalman is damned good, third out of maybe 50 on Frostytech's heatsink chart.
The only downsides I can see to the Zalman is that its 1) Expensive and 2) Heavy.  You have to be careful moving your case around with a heatsink that heavy on your processor, as a sudden drop or anything could rip the socket off the board.

As for the Thermaltake 11... well, the only 11 that Thermaltake makes is the Volcano 11, and thats AMD only.

I would go for thermalright heatsink but none of the stores have them, the only high end heatsinks they have is Zalman, Thermaltake, and Vantech Aeroflow. The oter choice is the watercooling, but that is too expensive or takes lots of effort to build it yourself.

I'd go for the zalman but be really careful moving your case, other than that I would go with a thermaltake spark7
