MSI N460GTX Cyclone Temperatures

It's hard to know exactly when the first video card got overclocked, and by whom. What we do know is that it's hard to imagine a computer enthusiast or gamer today that doesn't overclock their hardware. Of course, not every video card has the head room. Some products run so hot that they can't suffer any higher temperatures than they generate straight from the factory. This is why we measure the operating temperature of the video card products we test.

To begin testing, I use GPU-Z to measure the temperature at idle as reported by the GPU. Next I use FurMark 1.8.2 to generate maximum thermal load and record GPU temperatures at high-power 3D mode. The ambient room temperature remained stable at a very high 29C throughout testing. I know this is much higher than the average American household, but we had a massive heat wave this summer and my testing is done in an upstairs room that doesn't get as much of the central A/C as I would like... Besides, I know some of you are not living in iceboxes and would be interested in how well the GTX 460 handles high ambient temps. I do have a ton of airflow into the video card section of my benchmarking case, with a 200mm side fan blowing directly inward, so that helps alleviate the high ambient temps.

The MSI N460GTX Cyclone 1GD5/OC video card recorded 33C in idle 2D mode, and increased to 60C after 20 minutes of stability testing in full 3D mode, at 1920x1200 resolution, and the maximum MSAA setting of 8X. With the fan set on Automatic, the speed rose from 40% at idle to 70% under full load. Before we talk about the temps under load, it's worth it to pay notice to the idle temperatures. I have never seen idle temps this low above ambient, but if you follow along into the next section on power consumption, I think you'll see the explanation.

60C is an excellent result for temperature stress testing, especially with such a powerful GPU, stock fan settings, a high ambient of 29C, and fan speeds controlled by the card. I'm used to seeing video card manufacturers keeping the fan speeds low and letting GPU temps get into higher temperature regions than this. I applaud MSI for keeping the fan speeds up and the temps low with their stock automatic fan settings. I rarely do my benchmarking tests with fans set on Automatic, preferring to give the GPU or CPU the best shot at surviving the day intact. With an integrated temperature controller in play though, I want to show how the manufacturer has programmed the system. This is one of the few video cards where I like the manufacturer's settings, right out of the box.

Load temps never got higher than 57C when running continuous gaming benchmarks with automatic fan speeds, so the cooling system definitely does the job, and there is a lot of temperature headroom left for the GPU. The noise at 100% speed was much lower than some other products I've tested recently that had squirrel cage blowers. For me, this type of fan noise is less irritating than what a radial fan produces, but I still prefer a design that pushes all the heated air out the back of the case. For normal usage patterns including gaming, I'd leave the fan settings on Auto. For benchmarking, it's worth it to put up with a little more noise, and drive the fan at 100%.

FurMark is an OpenGL benchmark that heavily stresses and overheats the graphics card with fur rendering. The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration. The benchmark also includes a GPU Burner mode (stability test). FurMark requires an OpenGL 2.0 compliant graphics card with lot of GPU power!

FurMark does do two things extremely well: drive the thermal output of any graphics processor higher than any other application or video game, and it does so with consistency every time. While FurMark is not a true benchmark tool for comparing different video cards, it still works well to compare one product against itself using different drivers or clock speeds, or testing the stability of a GPU, as it raises the temperatures higher than any program. But in the end, it's a rather limited tool.

In our next section, we discuss electrical power consumption and learn how well (or poorly) each video card will impact your utility bill...

The fins at the base of the heat-sink spiral in the opposite direction to the fan rotation?

Whoops.

That removes laminar air flow through air friction, and delivers better cooling performance.

# Good Heat TransferBruceBruce 2010-08-11 07:07
For good heat transfer, you basically want the air banging into the surface of the heatsink. Turbulence is good, impingement is even better.

Well, I guess I should have taken an engineering class :)

I consider myself now a little more educated from your remarks, thanks ;)

Mini-HDMI is there on the board because of space constraints. You can't put anything else next to 2 DVI's on a single slot bracket.

Favourite benchmarks so far! Uses an almost identical system to me and includes the GTX260 (my current card), great stuff for working out if I want to upgrade yet or not.

FWIW, the Porsche 911 has been water cooled for more than a decade, and the tighter temperature regulation afforded by water cooling led to major increases in power and efficiency (parts could be machined to tighter tolerances since the narrower temperature envelope limited expansion of the parts). Still, for the time, the air cooled 911 was pretty good.

Just think what the engineers could have done with heatpipes...LOL

Seriously, you don't want to get into a discussion of air cooled vs. watercooled Porsches, do you? That's just begging for an invasion of the body-snatchers! Don't you think the comment section has suffered enough lately?

Thanks for the review, very informative! I currently have 2 of these puppies in SLI. I'm curious how the Gainward 2GB version compares with the 1GB versions

# Excellent reviewDr_b_ 2010-08-18 18:53
excellent review. glad you added the older 200 series in for comparison, there doesn't seem to be a reason to keep using the old 285 that i have now. going to SLI two of these.

# It was a great card in its day...BruceBruce 2010-08-18 19:05
I'm sure you got lots of good use out of it, but time and progress marches on. One of the things I like about the GTX 460 cards is that there is a variety of implementations. The ASUS that was reviewd here is another example of a solid non-reference design (4 phase PWM, etc...).

# Question for a purchaseKaelin 2010-08-23 03:58
Thank you for your very interesting article. I must change my graphics card but i hesitate between the MSI N460GTX Cyclone 1GD5/OC and the Asus ENGTX460 DirectCU TOP/2DI/1GD5... I don't know which one to choose =( Which one do you advise ?

(Sorry for my english level)

# Tough Choice...Bruce Bruce 2010-08-23 07:44
They each have larger fans and bigger HSF assemblies that both improve cooling and reduce noise levels. ASUS rolled their own PC board design, and it looks like they increased the PWM from 3-phase to 4-phase. MSI stuck with the reference design. I can't tell where you are located, but you may want to consider the support services that are available in your location, as well as local warranty provisions.

# Asus or MSI...Kaelin 2010-08-23 10:03
Thank you for your reply
I am French so the support service is not a problem (usually)
to help me to decide I would like to know wich graphic card has the cooling system more efficient and wich one has the best resistance to a higher overclocking. And to finish wich one do you prefer ^^

Thanks in advance

# RE: Asus or MSI...sportwarrior 2010-08-24 16:56
I'm also interested in the questions above... it seems that the two cards are quite similar in performance capability, though, so ultimately I'm guessing it doesn't really matter which I would select (I live in SoCal, for what it's worth). I will say I like the look of the ASUS quite a but more than the MSI, but Amazon is making me wait a ridiculously long time to get my card and I NEED to build my new rig very very soon.

# French Pricing?BruceBruce 2010-08-24 18:47
What are the prices for each, locally? I don't want to say that the two cards are the same, because they are not. But.....they both do an admirable job supporting the GF104 chip, in slightly different ways. I like MSI Afterburner better than ASUS Smart Doctor, so that's how I would go... If the ASUS card supported the ASUS iTracker2 software, it might be a different story.

# The choice is madeKaelin 2010-08-24 23:39
In France, the price difference is about 1 euro for the Asus graphics card. Moreover the Asus ENGTX460 DirectCU TOP/2DI/1GD5 is guaranteed 3 years against 2 for the MSI, that's the reason for why I chose the Asus.

thank you for your help =)

I would have gone with the Asus version too if it had come out earlier as it is $35 cheaper here than the MSI cyclone, both with 3 yr warranty.
