I’d like to thank Junpei of Thermo-link for providing us with the unit for review.
Today we're taking a look at one of the many heatsinks offered by AVC, the Tundra 2.
The Tundra 2 is an all copper heatsink with a 70mm fan that blows 34 CFM of air.
The fan comes with a fan guard and is tailed with a 3 pin molex. To keep the heatsink attached to the motherboard
a single lug retention clip is used.
SPECIFICATIONS:
AMD Athlon 1.4GHz
AMD Athlon XP 2200 +
AMD All Duron
Fan Dimension 70 x 70 x 15 mm
Fan Speed 3800 rpm
Air Flow 34 CFM
Heatsink Material Copper
Heatsink Dimension 70 x 63.5 x 37 mm
Rated Voltage 12V DC
The base of the Tundra 2 is quite thin compared to some heatsinks i've reviewed. The thickness of the base is about 1/8th of inch. The finish though is nice and shiny with no scratches or nicks.
As for the clip, i would have liked to see the 3 lug kind. Instead this clip is a 2 piece deal with the fastener part held by the rest of clip. During installation the fastener actually came off from the rest of clip, and i had to fix it back into place. This clip is also unusally springy and is kind of weak.
Test System
AMD XP 2600+ 333 MHz (AIUHB)
Asus A7N8X Deluxe rev 2.0
Corsair PC2700 XMS 512 MEGS
Beantech igloo 7 aluminum case
Maxtor Diamond 9 30 gig harddrive.
To calculate the idle temperatures, I let the computer run 10 minutes before recording the temperature down. Next, using Sandra burn in wizard I allowed it to run 30 minutes. For comparison, i've included some results from some other heatsinks.
As you can see from the results above, the idle temperature was 55 degrees Celsius and full load was 64. Those numbers are quite high for a copper heatsink in my opinion. I even re-installed the heatsink 3 times to make sure it was installed correctly. The only explanation i can come to is the copper base is to thin to actually do any good.
