Arctic Cooling NV Silencer 5 - Page 4 of 5

  
BENCHMARKS
I ran the following three tests. The time duration was chosen after monitoring each test to see where the temperatures leveled off under load. The card's ambient temperatures are also reported. The machine was shut off for 10 minutes between each of the three main tests.

UPDATE: Ambient room temperature was 20°C and the ambient case temperatures were 25°C at idle and 28°C under load.

UPDATE: I had already removed the stock thermal compounds in my review of the BFG 6800 Ultra OC. At that time I then replaced with Arctic Silver 2 on the GPU core and Ceramique on the memory modules. So, the "stock" comparisons below are actually better than the original factory compounds.

I also tested at stock speeds of 425/1100 and overclocked speeds of 460/1250. However, there was no appreciable difference in temperatures. The Silencer NV 5 did an excellent job at keeping even a well overclocked GPU and memory at the same temperatures found at stock speeds.

  • Windows at idle for 10 minutes
     
  • RTHDRIBL v1.2 for 15 minutes
     
  • Far Cry v1.3 - Research Map - 1600x1200 - 4xAA/8xAF - looped 10 times (~6 minutes)

I recorded the temperatures with the NVIDIA Forceware Control Panel. I also used SpeedFan v4.20 (after making the necessary +10°C offset for my GPU core temp sensor reading) as a secondary measurement for comparison.

Tests were taken with my case side panel both on and off. I have four Vantec Stealth 80mm case fans (one topside blowhole, two rear exhaust and one side intake). Also, the fans were left running when the side panel was removed. Yes, I need a front intake, I know...and my wire management is in a state of transition. :)

Case

REMINDER: The 6800 Ultra stock cooling is actually quite good. So, I wasn't expecting the near 20°C drop in load temperatures that some have been reporting on the 6800 GT. The 6800 GT stock cooling is clearly not as good as 6800 Ultra's. Let's find out how much of an improvement the Arctic Cooling Silencer NV 5 can make over the already excellent 6800 Ultra stock cooling.
 

Case Opened Results

In the results above you can see that there's a nice 4°C drop for the GPU at idle in Windows. We see a bit more cooling occurring in RTHDRIBL and Far Cry. My goal is to always achieve < 70°C under load which I reached easily with the side panel off.

Case Closed Results

First of all, the results above clearly show that I need to improve the cooling within my case when closed. I've never been a stickler for case cooling but I'm leaning more that way now. This case cooling issue of mine has a nice side effect though. It really helps to demonstrate how well the Arctic Cooling Silencer NV 5 performs.

We're about the same idling in Windows. What's impressive is the 8°C and 11°C reduction in temperatures with RTHDRIBL and Far Cry respectively. Also worth noting is the 3°C reduction in ambient temperatures whereas the there was a slight increase with the side panel off.

SpeedFan provides it's own graphing over time for the temperature sensors that you select. I thought I'd include these results as well. It's always nice to be able to see the trend over time. Below is a screenshot of the entire window and then following are just the graph portions.

SpeedFan Temperature/Time Graph

Even though I didn't include overclocked results in the graphs above, I thought I'd include them here for reference.


SpeedFan Results - Idle - Default Clocks - 10 Minutes

= GPU = Ambient


SpeedFan Results - Idle - Overclocked - 10 Minutes

= GPU = Ambient


SpeedFan Results - RTHDRIBL - Default Clocks - 15 Minutes

= GPU = Ambient


SpeedFan Results - RTHDRIBL - Overclocked - 15 Minutes

= GPU = Ambient


SpeedFan Results - Far Cry - Default Clocks - Looped 10x

= GPU = Ambient


SpeedFan Results - Far Cry - Overclocked - Looped 10x

= GPU = Ambient

Everything above looks as expected except for Far Cry when overclocked. It seems that Far Cry was hitching a bit at those clock speeds.
