Zalman 7000a (silver/copper)
Cooler Master Aero 4
Vantec AeroFlow 2
These are my options..
I got a 2.8E not o/c but would like to get it as cool as possible. Which one would offer the best cooling?
Thx in adv
I am on my way to pick up a Zalman 7000-alcu for $30 now to try it out. I have the aero 4 now which keeps temp like 49c but its loud. If the zalman keeps it under 50c and quieter then that would be good.
I had a zalman 7000cu and it is great (untill I killed the fan) now I invested in watercooling temps are better now but I must say the couple of degrees difference between a 30$ zalman and a 300$ watercooling setup aren't worth it when you don't overclock to the max so I can recommend the zalman but I don't know about the other coolers, the zalman is quiet as hell though and will probably be the most silent component in your system
I don't know why people overlook this HS or the Alpha PAL8942. Both have been around or so long but people must only want something new... New does not mean better.
Let us reason together shall we. I hope this will help you become more informed when you look for CPU coolers.
Heat Disipation is what it is all about. The Swiftech's heat disipation is not like most. With a simple <A HREF="http://shop.store.yahoo.com/inflowdirect/sun80quietca.h..." target="_new">$4 Sunon 25CFM 23dBA (Model KD1208PTB4) fan</A> it disipates at 0.307 C/W. (degrees C per Watt or Thermal Resistance) That is quiet and cool.
The lower the the score, the better it cools. It means that for every Watt it will only raise the temeperature X degrees. So if the score was 0.350 like what is listed above, the temperature above ambient would be 31.150 degres C at 89 watts. (<A HREF="http://support.intel.com/support/processors/pentium4/sb..." target="_new">See the Intel Thermal Managment specs for the 2.80E... It is 89 Watts.</A>)
The example I listed would be 27.327. That means 3.823 degrees cooler. Remember, that was the swiftech with a small low CFM fan.
Sorry for the delay, “Things to do and people to see.”
Anyway, I can't find a good reviews anywhere for this thing. Only one out of the six that I looked at had the ambient temperature given. To me, that is annoying when you are looking for objecive conclusions and the review has nothing but ending temperatures. I like seeing the before, after, the C/W, the processor (with or without an overclock... as long as it is sprcified) and the fan or fans used in the test.
Anyway, the one I found that had the before and after temps.
As you can see, they took a P4 2.4C which under normal circumstances is putting out 69.0 Watts. By overclocking it to 3.0GHz it would most likely be at 81.9 Watts.
That being said, now lets look at the before and after temps.
Ambient: 25.0 C
Load: 42.5 C
Peak/Max: 45.0 C
If you look at the <A HREF="http://www.1sweetpc.com/reviews/heatsink/slk948u/page2...." target="_new">picture here</A> you will see that the fan is most likely a <A HREF="http://www.thermaltake.com/accessories/dcfan/smartfan/a..." target="_new">Thermaltake Smart Fan-II</A>. The fan can give 75.7CFM at 4,800RPM and 48dBA. It is a great fan for an 80mm fan. I was happy to see that they used a real (normal) fan for the test. Unlike the beast that is "Stock,"
the Delta Electronics FFB0912EHE. It is 199 grams, has two axial fans (Dual sets of fan blades), and does 110.18CFM and 55dBA.
I will use the maximum figure, because it is the most that your CPU will throw at it so anything less would be at safer levels. In this example the C/W would be 0.244.
