Zalman 7000a (silver/copper)
Cooler Master Aero 4
Vantec AeroFlow 2
Thermaltake 7+
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 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

SL6EF OC's GOOD

<A HREF="http://www.swiftnets.com/products/mcx478-V.asp" target="_new">Swiftech MCX-478</A> with a good fan will still beat most if not all of the P4 heatsinks on the market.

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 Aero 4+ looks cool but at its best only does <A HREF="http://www.coolermaster.com/index.php?LT=english&Langua... 4" target="_new">0.350 C/W</A>.

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.

<A HREF="http://www.thermaltake.com/coolers/spark/a1715.htm" target="_new">The Spark 7+</A> beats the Volcano 7+ so I will use the Spark here. At 6000 RPMs and 43dBA it had a thermal resistance of <A HREF="http://www.svc.com/thp4sp7xaed.html" target="_new">0.260 C/W</A>. That is better but it come with the price of noise.

To compare, if the Swiftech had a Sanyo Denki (Model 109P0912H201) it would only produce 36dBA of noise but would cool at 0.220 C/W.

The Spark would be at 23.14 degrees where the Swiftech would have 19.58 extra degrees. It would still cool 3.56 degrees better and would be 7dBA quieter.

What about the Thermalright Coolers?
Like the SP-94 or the SLK-948U w/ a good 92mm fan ?

Tom had never done a TR HSF review though, even when PC-Cooling.de is right in Germany

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.

<A HREF="http://www.1sweetpc.com/reviews/heatsink/slk948u/page3...." target="_new">http://www.1sweetpc.com/reviews/heatsink/slk948u/page3....;/A>

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.

That isn’t bad but the Swiftech with the <A HREF="http:// http://www.q-tech.hu/pdf/SanyoDenki/DC_fan/092mm/102205..." target="_new">Sanyo Denki</A> would do 0.220 C/W and it would be 12dBA quieter.

Just to be fair to the heatsink, I will assume that the ambient temp from the review at <A HREF="http:// http://www.cluboc.net/reviews/heatsinks/thermalright/sl..." target="_new"> http://www.cluboc.net/reviews/heatsinks/thermalright/sl...;/A> was the same as the ambient in the 1sweetPC review.

They used four different fans. Let’s see how it did with each of the fans.

Y.S Tech TMD 70mm – C/W = 0.330 (0.329670)

Cooler Master LED 80mm – C/W = Same as above - 0.330 (0.329670)

Papst 3412-NGL 92mm – C/W = 0.31746

Vantec Tornado 92mm – C/W = 0.25641


Again the Swiftech does better than it with all of these fans.

It is like I said before. It is hard to look at cooler reviews because they don’t give enough real information to help you make an intelligent choice of which is best.

:smile: I hope this helps.
