INTRODUCTION


Heatsink fan technology has evolved tremendously in the past two years. First, we had the basic small aluminum heatsink coupled with a modest fan. Although they accomplished their job quite well, the advancement in CPU technology and the relevant increase in processor operating temperature with the new Athlon and Duron products warranted a design change. To overcome the increased thermal output of the processors, company's first move was to bulk up the heatsink and increase the surface area to improve the thermal efficiency. This proved to be adequate but the overclocking genre acted as a catalyst to really kick the heatsink engineering into action. People were overclocking their CPUs to the point that even the bulkier heatsinks were not cutting it. In marched the fans spinning at insane rates and pushing out incredible airflow numbers and equally impressive sound levels. Still, they proved not to be enough for the ever increasing overclocking rates and the heat values. The next step entailed leaving the existing screaming fans and instead improving the heatsink itself. Aluminum had reached it's thermal limit and another metal or alloy was needed. Copper seemed to be the most cost effective option, and out popped the latest craze, the all-copper and the copper-based heatsink. Copper heatsinks evolved to be the aircooler of choice in today's cooling market and still holds the crown. Today I will be testing 14 heatsinks in the full aluminum, copper-based and all-copper class of coolers and will be honestly displaying their faults and good points.


Enough of the BS, let's get it on!....

 

TEST SYSTEM


All HSF combos were tested on the same testbed, with the same room temperature (24 Degrees Celsius) and the same thermalpaste (Arctic Silver 3).


Here is the testbed..

Shuttle AK31 v2.0 (Provided by: Xtreme Tek Werks)
Duron 700 @ 800 (Pencil Unlocked)
Vcore 1.85 volts
512megs Crucial PC2700 DDR Ram (Provided by: Crucial Technology)
Western Digital 40Gb 7200rpm ATA-100 Hard Drive
ATI Radeon All-In-Wonder 8500 128meg (Provided by: ATI Technologies)
Samsung SW-232 32X CD-RW (Provided by Samsung)
Standard 1.44 meg Floppy
Windows XP Pro


All idle Temperatures were taken after an hour of idle time with only MbProbe running to take the temperature measurements. All Full-load
temperature's were taken after a full one hour of running prime95's torture test.


Testbed temperature was a climate controlled 24 degrees Celsius with all included case fans running during tests. For
information on the airflow for this case go HERE.

 

ROUNDUP LINEUP


Before anything gets started, this is a comparative roundup and results may differ with your system. All variables are constant except the cooler which in turn will show comparative temperature results.

 

Arctic Cooling Super Silent 2500


Manufacturer: Arctic Cooling
Donated by: Chillblast





Idle: 36 Degrees Celsius
Load: 40 Degrees Celsius


Being a very quiet cooler at a sound rating of 25dBa, this all aluminum cooler supports an 80mm fan that has an airflow of 31cfm through a 80mm to 60mm adapter. This cooler is not meant for cramped cases due to it's rather large size, but man, it's soo quiet. Now, if you are comparing temperature results, this cooler really hold's its own for a cooler that is 20dBa less than the rest. It has an easy to use full size clip that supports all 6 lugs on the CPU socket. Overall, a great cooler for stock conditions or a moderate overclock.

 

Dynatron DY1206BH-P625


Manufacturer: Dynatron Corporation
Donated by: Xtreme Tek Werkz





Idle: 31 Degrees Celsius
Load: 34 Degrees Celsius


Being the first of three Dynatron coolers that will be reviewed in this round up. It subscribes to what Dynatron is known for. Loud!! But with the high sound levels (45dBa) comes great cooling thanks to the all copper composition and the 6800rpm 38cfm delta. I'm not one for the loud coolers, but during the time that I loved them, this would be an awesome choice.

 

Dynatron DY1206BH-638


Manufacturer: Dynatron Corporation
Donated by: Xtreme Tek Werkz





Idle: 30 Degrees Celsius
Load: 32 Degrees Celsius


This big boy shares the same all-copper heatsink than the Dynatron above but has one major difference, the huge fan!! Man, this thing is big, and scary! Thank god for the fan guard, or this thing could really shed some light on your finger or should I say, the bone within it. At 7000rpm of 44cfm goodness, this baby screams for its bottle at a staggering 51dBa. But with all this power, you have a cooler that tied for the champion of this roundup. Tied with what cooler you say, well, that's to come, and it was a surprise too.

 

Dynatron DY1206BM-625


Manufacturer: Dynatron Corporation
Donated by: Xtreme Tek Werkz





Idle: 31 Degrees Celsius
Load: 33 Degrees Celsius


Bringing up the rear in the Dynatron line is the dense fin designed all-copper cooler. Including the black label 38cfm 45dba 6800rpm fan, this cooler also included some good results. Nothing breathtaking, but all in all, very good. One note with using this cooler, seeing the density of the fins, it gets clogged rather easily. So, if you are in a house containing numerous cats and/or dust, maybe this wouldn't be the cooler for you seeing that you would have to clean it every week to keep it running at full efficiency.
