Today we are going to test the Evercool Transformer 4 Plus with the AMD Phenom II X6 1090T Black Edition CPU. The AMD PII X6 1090T Black Edition ships at 3.2ghz but can hit 4.0 GHz (and above) when paired with the right cooling system.
We like to try and mirror ‘realistic’ conditions when possible, so instead of the open bench concept, we are mounting the build inside the NZXT Phantom Chassis. Room ambient temperatures were maintained at a steady 22c throughout testing.
Processor: AMD PII X6 1090T Black Edition
Coolers: Evercool Tranformer 4 Plus, NZXT Havik 140, Noctua NH-C12P SE 14
Motherboard: MSI 990FXA-GD80
Thermal Paste: Evercool Thermal paste
Power Supply: Corsair HX 850W
Chassis: NZXT Phantom
Memory: 8GB Mushkin Enhanced Silverline Stiletto DDR3 1333mhz Cas 9-9-9-24- 1T
Graphics Card: Sapphire 6950 2 GB (1536 unified shaders)
There are several different applications available that will load a processor to the limit while running through a series of complicated calculations. For today’s testing we are going to use the latest version of Prime 95.
Prime95 is a popular freeware application that can be used to stress test the CPU.
After 15 minutes of Prime 95 running to heat up the CPU we recorded our temperatures. The performance of the Transformer 4 Plus is very good, beating both the NZXT Havik 140 by 2c and the Noctua NH-C12P SE 14 by 8c, with the PWM feature enabled. While running the fans in this mode, the noise level was very impressive. The dual fans only reached 1,490 RPM compared to 2,200 RPM when we run them at 100%. There was a considerable drop in fan noise using the PWM feature, yet there was only minimal increase in temperatures.
Next we overclocked the Phenom II X6 1090T to 4.0 GHz and retested the coolers. Once again the Evercool Transformer 4 held down top spot by edging out the NZXT Havik 140 by 2c and the Noctua cooler by 5c with the fans running at full speed. When we enabled the PWM feature in our bios the Transformer 4 Plus was still able to edge out the Noctua NH-C12P SE 14 by 1c, while providing a very quiet experience.
