Eumax B605-01 Nickel Plated Copper HSF Review


When you think of heatsinks you may have Thermaltake, Thermalright and Alpha in mind. However those heatsinks are sometimes too expensive for people who want a good price. Some people think you get what you pay for but what would the Eumax B605-01 HSF be like for only $8? Let’s take a look and find out.

The Eumax B605-01 HSF arrived in perfect condition in a brown box with Styrofoam bits to prevent any damage.  The presentation of the box is revealing with information on more products that Eumax has.  One interesting thing that caught my attention is that the Eumax B605-01 HSF is made out of copper.  However not only is it made out of copper, it is a nickel-plated copper based heatsink/fan solution.  Whether this actually plays a role on performance remains to be seen.  An interesting thing to note is the thermal conductivity between copper, aluminum and nickel.

Thermal Conductivity from efunda
Aluminum: 237 (W/m·K)
Copper: 410 (W/m·K)
Nickel: 90.7 (W/m·K)
**Higher values are better**

Included in the package were the heatsink/fan itself and thermal compound.  Arctic Silver 3 will be used as the thermal compound in testing.

The Eumax B605-01 looks and is very compact in size and fits in most motherboards with no problems.  As you can see, the cooler utilizes skived fins that allow the air to be effective throughout.  I liked the use of a 3-prong clip as it provides coolers to be stable on the motherboard.  The only problem I found was that the 3-prong clip's guide where the flathead screw driver goes wasn't very good.  There are high chances your screw driver will slip and hit possibly your motherboard.  Fortunately, I hit my carpet:)

The Eumax B605-01's fan rotates pulling 33.73 CFM's of airflow @ 3800 RPM's and reaches 32.3dBA of noise.  When I listened to the fan, I thought it sounded louder than 32.3dBA's.  It was relatively loud but was very bearable.  It was not loud as the Dynatron DC1206BM-L/610-P-CU we reviewed a few months back.

The bottom of the Eumax B605-01 was flat with little machine marks as you can see when light is reflected off the coolers base.


Testing will consist of what we usually do.  We will be testing the Eumax B605-01 on an AMD Athlon XP 1900+ after the Arctic Silver 3's 72-hour set in period is finished.  The ambient air temperature was 21-23c.  Idle temperatures were taken after 30 minutes of idle and load temperatures were taken from two sources.  One hour loops of UT 2003 and 5 minutes of Toast.  Temperatures were taken off Soltek Hardware Monitor Ver.2.04 on a Soltek SL-FRN2-L.  More information on our setup here.  A comparison between the Spire FalconRock II on our Soltek mainboard will be used.  These are two budget coolers. 


Spire FalconRock II Eumax B605-01
Idle: 35c Idle: 34c
Load (UT 2003): 44 Load (UT 2003): 44c
Load (Toast): 45 Load (Toast): 44c

As you can see the Eumax B605-01 did a pretty good job at cooling down the Athlon XP 1900+.  It beat out the Spire FalconRock on two of the three tests by a degree. 


The Eumax B605-01 HSF is a really good cooler.  The fast-spinning fan with a good base helped the cooler maintain a solid temperature throughout testing.  The only problems I had were that I disliked the 3-prong clip guide where the flathead screwdriver will go and also the fan I felt sounded louder than the specs say.  Other than that, this thing is $8 U.S. and that is a crazy price to go by.  If you are looking for a cooler that performs and is cheap in price, you can't really go wrong with the Eumax B605-01 Nickel-plated cooler. 

I rate the Eumax B605-01 HSF a...
