YOYOTech Warbird SB2500-460 System Review

Temperature Performance

To measure temperatures we started the system and let it idle for 30 minutes. To test load temperatures we used Prime95 and loaded the CPU for 30 minutes.  We measured temperatures with Everest Ultimate and room temperature was maintained at 20c throughout the tests.

The Thermaltake Contac29 cooler does a reasonable job of handling the overclocked CPU in this system but the temperatures are a little on the high side for our liking, but they shouldn't have a huge affect on the longevity of the system. We think Yoyotech should contemplate a higher grade cooler for this system such as the Thermaltake Frio.  The graphics and hard drive temperatures are exactly what we would expect.

Acoustic Performance

We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.

Today to test the chassis we have taken it into our acoustics room environment and have set our Digital Sound Level Meter SL-824 one meter away from the case

As this can be a little confusing for people, here are various dBa ratings in with real world situations to help describe the various levels.

KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum

When idle, the Warbird is certainly audible but we could exactly describe it as loud.  Under load, though, the system noise becomes much more noticeable and this isn't surprising considering the temperatures reached by the CPU.  But if you're gaming with a headset or speakers, you won't notice the system at all – so this isn't a huge issue.
