With a copper base, how does this less than $20 heatsink perform? Let's find out...

Note: We have since changed our temperature measuring from using the onboard sensor on the motherboard, to using the CompuNurse, an external temperature probe.  This probe is situated right next to the CPU slug, so it provides the most precise temperature reading as possible.

   Our installation was made on our AMD T-Bird test rig.  It consists of:

  • IWill KK266 Socket A Motherboard
  • AMD Thunderbird 800 (Arctic Silver)
  • Crucial PC133 128MB CL2 Sdram
  • EVGA GF2 MX 32MB AGP Video Card
  • Windows 98SE

For our tests, we recorded the temperature of the cpu at idle and at full load.  Full load consists of running Distributed.net's RC5 and MadOnion's 3D Mark 2001 Benchmark programs.

   ***Note: After thinking it over, we have removed the OCZ and FKP-32 temperature results our temperature checks.  They were originally recorded using the onboard temperature sensors, which is not at all accurate to my knowledge.  I originally left it there as a reference, but since some people were getting confused about it, I'm going to remove it from this review and here on after.  Thanks to a few people who sent in comments about it, I wasn't sure if I would have removed it without some reading some of these comments first.

Seems this unit does a bit better than its all copper cousin.  Now what I am wondering after these temperature readings, is whether or not the thermal grease between the copper layer and heatsink is what is holding it back.  Copper transfer heat a lot better than aluminum, but how much can the aluminum in this heatsink, take from the copper.  Seems that at lower clock speeds, the temperature runs a bit high.  It is however, very close to what the overclocked temperatures are at idle and full load.  If you compare the results, this quieter unit ranks almost as well as the big boys.

So overall, this budget cooler did cool the best out of the lot.  If I could pry the copper off, maybe I could try slapping on a layer of Arctic Silver grease.  Then again, this isn't how the heatsink was designed so I'm not even sure if that would cause any difference in the end.

If you're in the market for a cooler, but money is an issue, these units may suit you rather well.  Thanks to Cyber Cooler for sending us over a different unit, it's nice to see interesting ideas in the design of heatsinks every now and then.


  • Very affordable
  • Quiet fan
  • Copper base

  • Cons:

  • Copper and aluminum are attached with regular thermal paste
  • Fan speed is a bit low
