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.
This unit comes with a 32CFM fan, which we did not replace. What we did was use the fan that came with it and then test it afterwards with a Delta 38CFM to even all the temperatures out with our other coolers.
Our trusty old test rig is as follows:
IWill KK266 Socket A Motherboard
AMD Thunderbird 800Mhz CPU
Crucial PC133 CL2 Ram, 128MB
The test will consist of an idle temperature check and a full load temperature check. The full load will be accomplished by using the RC5 program and running 3DMark 2001 for 30 minutes.
Here are some results:
AMD Tbird 800 Stock
AMD Tbird 800 @ 1003 (1.85V)
|Ambient Temp. = 27C
|ThermalTake Dragon Orb 3
|SVC Golden Gate 40
|>> Thermal Take Volcano 5 <<
|> Volcano 5 w/38CFM Delta <
This unit seems to perform better under higher temperatures. The overclock speeds yielded better results in the temperature comparison. The black cover on the top of the unit under the fan may have played a part in this unit's performance. It may be directing the air from the fan directly through the heatsink without it escaping from the top. Switching the fan to a Delta fan didn't offer that much more performance. From what I see, I think I'll take the quieter fan any day.
With this type of performance with a very nice price tag of only about $20, make sure you give this one a look. The lower noise level and equal performance with some other high performance units, this may be the best bang for the buck as of yet. For now, its a toss up between the SVC GG 40 and this unit for the Best Bang for the Buck award.
Thanks to Kenny at Thermal Take for sending us a test unit, these guys at TT know what it takes to make a heatsink. Give them a shot, you may be pleasantly surprised in what you find.
