6 – GTX 660 HAWK Burn-in Test

MSI GeForce GTX 660 HAWK - Burn-in test - MSI Kombustor

The aim of the burn-in is to reach the maximal GPU temperature and power consumption. The burn-in test allows to test the efficiency of the cooling system as well as the quality of the power circuitry. For this burn-in test, I used the furry test of MSI Kombustor 2.4.2.

The first thing to do before starting the burn-in test is to set the power target to the max. In the case of the GTX 660, the max power target is 114% TDP. To set the power target, just use MSI Afterburner.

At idle, the total power consumption of the system is 56W and the GTX 660 HAWK temperature are:
GPU: 27°C
VRM: 34°C
– Memory: 37°C

After around 10 minutes of stress test (furry donut, 1024×768), the total power consumption of the system was 266W and the temperatures:
GPU: 79°C
VRM: 95°C
– Memory: 85°C

A rough estimation of the power consumption of the HAWK is:
P = (266-56-20)*0.9 = 171W
where 20 is an estimation of the CPU power when the stress test is running and 0.9 is PSU efficiency factor.

The VRM is rather hot but still ok. The GPU took around +50°C which is normal with such burn-in test and the good news comes from the VGA cooler: still quiet even under heavy load!

The GTX 660 HAWK took around 10 minutes to reach the idle temperatures:
