GeForce GTX465 Temperatures

Benchmark tests are always nice, so long as you care about comparing one product to another. But when you're an overclocker, gamer, or merely a PC hardware enthusiast who likes to tweak things on occasion, there's no substitute for good information. Benchmark Reviews has a very popular guide written on Overclocking Video Cards, which gives detailed instruction on how to tweak a graphics cards for better performance. Of course, not every video card has overclocking head room. Some products run so hot that they can't suffer any higher temperatures than they already do. This is why we measure the operating temperature of the video card products we test.

To begin my testing, I use GPU-Z to measure the temperature at idle as reported by the GPU. Next I use FurMark's "Torture Test" to generate maximum thermal load and record GPU temperatures at high-power 3D mode. The ambient room temperature remained at a stable 20°C throughout testing, while the inner-case temperature hovered around 37°C.

FurMark does two things extremely well: drive the thermal output of any graphics processor higher than applications of video games realistically could, and it does so with consistency every time. Furmark works great for testing the stability of a GPU as the temperature rises to the highest possible output. The temperatures discussed below are absolute maximum values, and not representative of real-world performance.

ASUS GeForce GTX-465 Video Card Temperatures

NVIDIA-supplied product specifications state that the GeForce GTX-465 has a maximum GPU thermal threshold of 105°C. This is identical for the previous-generation GeForce GTX 285, as well as the GeForce GTX-470 and -480 that share the same GF100 graphics processor. In a room with 20°C ambient temperature, the ASUS GeForce GTX-465 produced 45°C at idle and 82°C under load. It wasn't until FurMark has raised the temperatures to an unnaturally high level that the fan began to become audible. Otherwise, operation remained silent during game play.

Comparison: GTX-470 & GTX-480

Housed in a mid-tower computer case with no additional cooling, the retail NVIDIA GeForce GTX-470 video card produced a luke-warm 40°C in idle 2D mode and increased to 88°C in sustained 100% mode using FurMark's torture test.

Zotac GeForce GTX 470 Video Card Temperatures

Compared to the NVIDIA GeForce GTX-480 retail kit, temperatures are extremely close. Let's not kid ourselves into thinking that the GTX 470 should be cooler-running simply because it's a lower model, because the difference in thermal management is clearly obvious from the beginning. The image below illustrates temperatures on the GTX-480 using FurMark to produce load:

ZOTAC GeForce GTX480 Video Card Temperatures

Most new graphics cards from NVIDIA and ATI will expel heated air out through exhaust vents, which does not increase the internal case temperature. Our test system is an open-air chassis that allows the video card to depend on its own cooling solution for proper thermal management. Most gamers and PC hardware enthusiasts who use an aftermarket computer case with intake and exhaust fans will usually create a directional airflow current and lower internal temperatures a few degrees below the measurements we've recorded. To demonstrate this, we've built a system to illustrate the...

Best-Case Scenario

Traditional tower-style computer cases position internal hardware so that heat is expelled out through the back of the unit. This is better than nothing, but there's a fundamental problem: heat rises. Using the transverse mount design on the SilverStone Raven-2 chassis, Benchmark Reviews re-tests the ASUS GeForce GTX-465 video card to determine the 'best-case' scenario.

Sitting idle at the Windows 7 desktop with a 20°C ambient room temperature, the GeForce GTX-465 rested at 42°C, which wasn't much less than a regular computer case. Pushed to abnormally high levels using the FurMark torture test, the GeForce GTX-465 operated at 78°C with a very quiet cooling fan. While the many BIOS revisions leading up to retail availability have obviously made a noticeable difference, the well-designed Raven-2 computer case with additional cooling features has help to make an even bigger difference.

Despite the 40nm process and improved BIOS programming, GF100 still runs warm unless you add internal case cooling to draw in cool air and exhaust heated air. This could impact overclocking projects inside poorly ventilated computer cases. So if you've already got a warm-blooded CPU in your computer system, take look at our Best CPU Cooler Performance series and find a heatsink that will lower your internal temperatures and prolong component lifetime. Lowering the internal case temperature could give you an added edge for GPU overclocking projects, and it will also help overall system stability.

# Little mistake...BETA911 2010-06-21 23:33
At Battleforge, how can a none DX11 card (9800GTX+) be in the charts when DX11 is tested? Same with the HD490.
Then, the HD5770 is not 256-bit but 128-bit!

Thanks for finding that typo - it's been fixed. I'll update the chart, too, since those products shouldn't be included. Even though the game allows them to benchmark with the same settings, they're not compliant and likely ignore the DX11 extensions.

# A Strange review pt1The Crouch 2010-06-22 11:50
I'm really sorry, but this review does not make much sense to me. Not compared to other reviews mind you, but in itself!

I count 5 clear wins for the 5850, 3 for the 465 and one wash (Resident evil 5). From the 465's point of view, thats a staggering 67% more wins for the 5850!!

When it comes to the value numbers you provide I count 5 wins for the 5850 and 4 for the 465 (RE5 is clearly a 465 win).

And by the way, I don't count the two parts of 3D vantage as separate tests.

So not only is the 5850 the faster card with over half the tests won, more importantly, it also offers the most bang for your buck! All according to your own figures!

At least to me, this would count as a clear win for the 5850, but that is hardly what I see in the summary.

Also worth mentioning i think: Having been on Newegg on a few occasions, $305 seemed a bit steep for a 5850, and for aspiring customers for a graphics card, I can tell a 5850 can be found for $285. Only $5 more expensive than the price for the 465 you are quoting, and with that small difference I think the value numbers throughout the test would look a bit different.

Based on NewEgg prices today, nearly every single Radeon HD 5850 is priced above $305 with an average price of $325 (I did the math). Conversely, several models of the GTX-465 sells for as little as $250, with an average price of $260. That makes the Radeon HD 5850 22~25% more expensive... but does it perform 22~25% better? No, it doesn't. It doesn't even perform better than the GTX-465 all of the time; only 'some' of the time... slightly more than half (as you point out). So should a card that costs $55-75 more than GTX-465 be considered the best value when it doesn't even offer a relative boost to performance? I don't think so.
You should also check your math on the cost per FPS, because the GTX-465 beats the Radeon 5850 in nearly all of them.

# Thank you !SiliconDoc 2010-06-27 17:10
I came here to see just how much red raging rooster ATI bias was here on the gtx465.
I thank you and congratulate you for your response to the commenter.
I sit here absolutely STUNNED. I can't believe that somebody didn't just "take it" and nearly agree with the ati fan fraud.
THANK YOU SO MUCH.
My faith in humanity has been renewed.
Believe me, I really, really appreciate it.
Sincerely sick of the rampant red bias,
SiliconDoc

# Is a 1~2 FPS lead really a win?Olin Coles 2010-06-22 17:54
Is a 1~2 FPS lead really a win? You might see it that way, but I don't. Especially when the Radeon HD 5850 costs $55 more.

About the VGA Power Comparison that you did, can you provide a sample calculation on how you came up with your data?

Did you just report the AC Power differnence between no graphic card in the system and with the Graphics card installed? Did you try to take into account the PSU efficiency?

From the power consumption section: "A baseline test is taken without a video card installed inside our test computer system, which is allowed to boot into Windows-7 and rest idle at the login screen before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for each specified test product."

Power supply efficiency is not taken into consideration for any of our reported results. Only the motherboard, processor, memory, SSD, and video card are drawing power. The math is simply idle/load result minus baseline.

# Weird...xtremesv 2010-06-22 18:04
Why do reviewers still benchmark FarCry 2? Is it a requirement recommended (imposed) by Nvidia?

And I don't get your pricing figures. I found a 5850 for $285 and another for $305 in Newegg... the ones you mention beyond $325 include special cooling designs.

hey do you know that i got my zotac gtx 465 at just 7250 which is $147.17(converted to USD) and the 5850 costs 14950 which is $303.48.At this price i can sli a gtx 465 and when you sli a gtx 465 against a 5850 clearly 465's the winner.I dunno why the prices aren't coming down for the 5850.
