6 – GTX 660 HAWK Burn-in Test
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:

Unigine Heaven has a lower score under Linux ONLY when using AA, it’s a known thing and they did not bother to fix it, so yeah, comparisons are useless, try without AA, with Tess: Extreme and they’re on the same level.
Thanks Licaon_Kter, I’ll do again the Heaven benchmark without AA. It’s time I release my new tests under linux and win….
I just tested with the following settings:
– 1920×1080 fullscreen
– no AA
– 16x aniso.
– shaders: high
– Tessellation: extreme
Windows: 50.7 FPS, Scores: 1278
Linux: 36.3 FPS, Scores: 915
– Tessellation: normal
Windows: 65.9 FPS, Scores: 1660
Linux: 49.3 FPS, Scores: 1243…
wtf?
On my plain GTX460/700/3600, tested with the same settings for Heaven 3.0:
-1920×1080 fullscreen
-no AA
-16x aniso.
-shaders: high
-tess: extreme
-Linux 310.14 / Windows 310.33 & 306.97
Linux: 23.4 / 589 / 12.1 / 59.3
WOGL: 23.4 / 588 / 11.9 / 61.2
WDX11: 24.6 / 619 / 12.5 / 66.6
That’s just ~5% difference…
Either you forgot to disable VSync (as it’s enabled by default on Linux) or there is something else at fault, like your DE/WM compositor, etc.
I tested with Heaven 2.1, maybe that could explain the difference. I’ll try with Heaven 3.0 as you did.
